Hi Anyone have an idea on this? My new tyre is going flat after 10 miles at highway speed. Yet same tyre will remain properly inflated for weeks not being ridden. Also does not go flat if bike is just ridden around town and leisurely rides any ideas?

Sounds like a valve issue.

Chiz,
Sound likely. Brush or spray soapy water on and around the valve, maybe flex it in the hole a bit. Dishwashing liquids like Dawn makes good soapy water. Otherwise, check the tire for a nail or staple somewhere, maybe with more soapy water if you do not see a problem.
Spray some around the bead also.

Yep, mine bubbles up when you push the valve, needs tightening

Well, tyre temperature, pressure and centrifugal force all increase with speed, take your pick.
I always get my valve stems changed with the tyres, which at the time was a couple of times a year, the picture below was taken two days after new tyres were fitted. It let go on the highway 2000kms from home late on a Friday afternoon miles from the nearest town.

It would hold air going slow but would deflect with centrifugal force (presumably) if I went too fast and deflate quickly. While unrelated to the valve issue, I notice when the tyre came off there was a build up of rubber around the bead seat that was much older than the current tyre, this often leads to recently fitted tyres not sealing properly.
The one time I recall experiencing your exact problem, it turned out to be a puncture that for some reason behaved in that odd way.

Like Balky said, do the bead also.
I just remembered, on the last rally one of the bikes had this exact issue after plugging a puncture.
The puncture was slightly elongated and the plug would seal for low speed, but was no good after a few bumps or higher speed and a mushroom shaped special rubber plug fixed it.
So, three checks, valve, bead, or puncture.

For a puncture at an angle, unfortunately, the rope plugs are all that will work, considered to be a (very) temporary low speed fix until you can patch the tire from the inside....however, if it's a straight in puncture, you're better off because those mushroom plugs are the best. Put the plug in via special tool, pull on the stem until the cap seats against the inside wall of the tire....and Bob's your uncle.
I love my Stop and Go tire plug kit. I go nowhere without it.

Have you had occasion to use it?
Several times, it works a treat.
I need (3) of the 16oz co2 cartridges to fill my front tire and (5) for my back tire.....(wear gloves)

Do you carry a compressor?
Not yet...I'm considering getting one.
Many years ago I had a problem running an air compressor to fill a tire and it ran down my battery.
The co2 cartridges have worked well so far.. here's a post from 2011 where I had multiple punctures at once.

Hey Dan, no, I have not had a bad experience with the Stop and Go 'schrooms. I used them only once, but I used 5 of them.
Exiting the freeway at night some dip shit contractor spilled a box of lath nails on the off ramp. In my well worn Mich. Pilot Power 2CT's I picked up 2 nails in my front tire and 3 in my rear tire. The nails were everywhere, I could not avoid them.
Stopping at a well lit strip mall parking lot I pulled the nails and reamed the holes with the rotary file and put the plugs in. I remember with the small holes, I had to work the insertion nozzle back and forth into the tire to get the proper depth so the caps inserted correctly.... I filled the tires with the 16oz CO2 cartridges, 3 front 4 rear. Trimmed off the plug tails and then cautiously rode 120+ miles home. No leaks. I did throw away the worn tires the next day.
Getting the nozzle tip past the tire tread and into the caucus was the key. Reaming the hole a bunch, made it easier. Some spit helped. I fully expect Klavdy to comment on this post in....3.....2.....
One thing I did notice, the mushroom plugs are soft. If you have a broken wire belt in the tire, or something sharp in the tire carcass, this could cut the soft stem of the 'schroom.
Cheers!
Since this post, I have used my kit 3 other times....all with great results.

I agree Pat, it's a great system.
I also bought the larger diameter plugs to go with my kit( just in case) and yes, it's always under the seat.
I have the kit in the pictures below and used it 2 times and it works great .I have never had to replace the tire after it was fixed and used it all its
lifetime afterward .I post a pic of a tire on the fj that punctured when almost new.The nail was down in the threads so i was unsure if i could rely on the
repair,but it lasted the tire lifetime.
found a video of a almost similar kit on YT https://www.youtube.com/watch?v=M5_nK8V-nU0 (https://www.youtube.com/watch?v=M5_nK8V-nU0) but it has a different connector to the co2 patron .One thing i don't understand is why he uses 3 patrons to fill the
tire watching the video made me thinking :bomb: If i remember right i used only 1 when i filled my tire and
the pressure in the tire felt high.I used the kit 2 times and i have used 2 of the 3 co2 patrons that comes in the kit ..Maybe the pressuregauge that was used in the video is
wrong or the co2 still to cold to read the actual pressure.
Anyway it is a must to stop at nearest gas station to replace the co2 with air.
On another bike i had problems with a leak in the bead. After replacing the tire it still leaked in the bead .I then used the stuff that comes in aerosolcan
and it fixed the leak. Next time when the tire was worn out and replaced the same happened so used the fix a flat in aerosol can again and the leak stopped.
I think the reason for the leak in the bead was me not being careful enough when replacing the tire at home and made a scar in the rim
On my car that has puncture free tires i had a puncture!! :shok: yes sounds strange ,but it does puncture but the tire does not get flat just a little lower
sidewall and you can drive
with a speed of max 80 kmH to get to a place to patch or replace the tire.Or as the manual says to the Dealer =) I found a little nail that i pulled out and used a can fix a flat stuff and it worked great that is 3 years ago.

Rolf, rims often get rubber stuck to them where the bead sits, you need to thoroughly clean it with each tyre change or risk the bead not sealing properly, I use a wire brush in a drill.
I have always used a puncture kit the same as yours but the plugs Pat mentioned look interesting. A bit of research suggests carrying both is a good idea, they don't take up much room. Like you, I have long since stopped treating them as a temporary fix and leave them in there for the life of the tyre.
It's not a bad idea to check the glue and plugs occasionally, they both dry out over time and a fresh card of plugs and tube of glue are cheap.

Do!
I get a lot of punctures and the repairs don't always follow the script. Stick making a hole too big plug, multiple punctures (7 plugs and still leaking like a sieve from other holes) the valve stem I posted yesterday, botched repairs that haven't sealed properly etc.
However, the one single event that has given my compressor the most work over the years is helping other riders who
didn't have one, just CO2 canisters!
I've probably used my compressor a dozen times where canisters wouldn't have been enough.
I've also taken to letting my tyres down if I'm on unsealed roads for a few hundred km's or more, it handles better and the tyres are less likely to be damaged.
Noel
Yep, you're right...I'll get one. Today's mini compressor's seem to be small and efficient.

Noel Thanks for that tip i never payed so much attention to the surface the bead sits, next time i get my reading glasses on and use your technique ! :good2:
Also thanks for reminding to check the repairkit more thoroughly took a closer look and to my surprise i fond a flat emptied gluetube and when looking at the one co2 canister i have
left it had a hole in front :biggrin: i was thinking hmmmm then used a toothpick and it confirmed that it was definitive used why did i keep that in the repair set wallet :scratch_one-s_head:
so out i ride to fill the repair set with new stuff if it isn't cheaper to just buy another set

Old Rider,
As most body'n'fender guys will tell you, hands and fingers often work better than just eyeballs alone, for finding defects in smooth surfaces.
Running a hand around the rim at the bead is a good "second check" for dirt or dings.
Just out of curiosity, has any one else seen this from Ryan at Fort Nine?
https://www.youtube.com/watch?v=Qm6fTWaj3QE (https://www.youtube.com/watch?v=Qm6fTWaj3QE)
Interesting, thanks Gavin. I've never had a mushroom plug push into a tire or leak air.
If I had just one choice, the traditional red string plug is by far the most versatile...mushroom plugs do not work when the puncture is at an angle. Still, I carry both, it's no big deal.
Good PSA on checking your tire kit components. I have discovered that I have some new stuff I have to buy...
Thanks folks

Noel,
Maybe those valve stems will not fit, but metal valve stems come in a wide variety of shapes and sizes lately. If you know the hole size that you have in the rim, shop around. I prefer the metal valve stems which seal with a common O-ring, not using some special rubber gasket that you can not find.
I quit using the rubber valve stems, for all my vehicles.
I switched back to the traditional gummy sticks after several failures with the mushrooms. I like the quality of the mushroom kit, but it just kept leaking. I've never had a gummy stick fail.
I carry a Dynaplug compressor. It's small and more than sufficient.

I carry this in the glove box on my car. I will also bring it on longer motorcycle trips. It's not super quick, but it does the job. And if necessary, it fits in a pocket

My new Toyota doesn't come with a spare... doesn't even come with a jack or lug wrench. Just a bottle of "emergency puncture repair" basically Slime and an air compressor. Had a nail and a flat at the other day. Went to pop the spare on and low and behold. There is no spare. Since the emergency puncture repair hooks into the air pump it is costly to replace. Around $75-100, which is a lot more than a plug kit. So now there is a plug kit in the back. I'm even think about just getting a jack and spare out of an older Toyota and toss them in the trunk well.
The sealant expires after a few years annnnddddddd you are also recommended to keep the vehicle under 50MPH, just like a normal donut tire anyways. Cheaper for the manufacturer = more of a PITA for the consumer.
Buddy at work had a blow out in a rental car in the middle of nowhere a couple years ago. No problem - put the spare on and call it in at the hotel. Nope. Can of slime and a compressor ... and a long wait for a service truck!
My car that is a 2010 model came without spare tire or jack not even a fix a flat can .it is delivered with runflat tires if i get a puncture i get a message
in dash telling me that there is low tirepressure and says drive straight to nearest dealer keep speed below 80 km/h .I had one puncture and since it was a
small nail i just filled tire with
fix a flat and it has been good for 3 years
I use to change the summer/winter wheels myself and had to buy an adapter to put on my jack. without it the plastic jackingpoints get damaged :nea:
I'm surprised that someone would sell a car without a jack in Norway. As Old Rider says, we all have to change our wheels twice a year and I believe most people still do this job themselves. I know I do, and I'll keep doing it for as long as I'm able to.
My wife and I were recently thinking about buying another new car but the main criteria was that it had to have a full size spare wheel. We like doing road trips on our holidays and because we live in Australia where vast distances can be traveled in the middle of nowhere with no phone coverage, a space saver spare or repair kit just wouldn't cut the mustard. That narrowed the field by a huge margin and can't understand why the manufacturers don't give some countries that option, it's definitely a deal breaker.

Very true Tony, Australia is unique in that regard.

I will go out on a limb here...... :sarcastic:
I don't believe it has much to do about keeping the cost of the vehicle down. :nea: My thoughts are..... fuel mileage. With a couple of States and the Federal Government mandating specific MPG minimums. It is all about weight. Dropping 20-40 pounds of weight by eliminating the spare tire, jack and tire iron helps to get better gas mileage.
Fred
I'm with you Fred, but it's all about emissions - use less fuel, make less emissions. And lts not geared to real life driving. It's all geared to getting the best figures in Govt mandated approval/ratings tests - hence why these auto stop/start systems are turning up on every new car now. They're a pain in the proverbial when driving, but help to get better emissions test numbers in the lab approval trials !!
That could be Fred but I don't think the 20-30 lbs makes that much difference for minimum MPG especially since it is getting around 60 MPG as it sits. I would gladly take a useable spare and sacrifice a MPG or two.

annnndddddd the tire shop will charge you to remove the shit from the inside of your tire before they can repair it... Audi has had this setup since mid 2000's and it sucks. It has always worked for me however. Tubeless bicycle tires have a similar stuff you run in the tires to repair on the fly if you do get a smaller puncture... nice technology.
I think folks like us that might replace their tire rather than call roadside assistance don't really drive the market. At least the goo/pump method is something pretty much anybody could attempt without threat of damage or injury... and it does appear to work pretty well.
I do think it's funny that, for the Audi models I own anyway, the goo and pump are housed in a big foam piece molded to fit in the spare tire well already designed into the cars... It would be easy to just junk that setup and put a donut spare in there.
Dumbing down of cars is one of the great tragedies of our lifetimes IMHO... who even teaches their kids to check tire pressures anymore? The robot will take care of us...

Same on the Toyota. It's a big hunk of hard foam molded to the inside of the spare tire well.
