Small slice cuts deep

[andyoutandabout]

Remember having to fight to get a bike shop to patch a tire. He did it, didn't recommend it, wouldn't give me a receipt and said it was all on me if it went boom.
Only considered the patch as the tire was nearly new; less than 500 miles.
Anyway rode really careful for a bit and then, as you might expect, forgot all about it and enjoyed the summer.
Had no problems the entire life of the tire.
So it is possible to get a solid repair with today's wonderful tire technologies.
Maybe it all comes down to how much you care to rely on your luck.

It reminds me how attorneys have screwed us all.......

Someone had a patch/plug fail, sued, won, and now we all pay.......

Think "grass in the road" tactics

On our way home from the RPM rally we planned on stopping by the Alpine air strip to do a high speed stability test of our saddle bags but while we were parked in Angels camp I found this thin slice in my front tire and decided not to.

Similar one here, just thought I'd run over something sharp but it's just an odd way it's cut

That is very similar to the slice that was on my front tire.all three slices don't involve the edge of the water grooves. The one on my rear tire is inside the lowest surface of the tire but no marks around it. I'm leaning more to these being a defect. How deep does the slice on your tire go? I love how the sport demons handle but with yours included that makes three tires with slices I had one with a sidewall bubble and one that had severe sidewall Dry rot at 1200 miles and only two years from the date of manufacture. Between that and the average three thousand miles until they are completely bald makes these tires expensive. With three fj's with 16" wheels it's a bit depressing.

Maybe consider going to 17 inch wheels and use modern radials.

What about the Avon 3D storms?
They come in 17 and 16 sizes

[T Legg]

Your right  Fred .I have  the front forks and stock 17" fj front wheel but I need to do the rear wheel at the same time and I don't like all the problems with the brake caliper mounting.I need to start researching my options.  Andy I need to check again but I don't think Avon makes the rear tire in the right size.

I bought my brothers 70 Buick gs stage 1. He had changed the rear end. And the one he put in had higher gearing. Speedo went to 120. But the needle would keep going all the way around too park.  My other brother was a cop. And he clocked it @156mph. I was always worried about the tires on that car too.

When I was eighteen I had a  1970 Pontiac tempest with a ys400 motor. It started out with a little turbo 350 transmission which I blew up twice. then I put a turbo 400 tranny and blew up the rear end so I borrowed my brothers 4:11 positrac rear end with his m-50 rear tires.those tires were so wide that if I took a corner too hard I could watch strips of rubber flying off the tires from the fender wells cutting into them I ended up breaking the posi rear end while burning off my tires.It gave one hop and then cracked the pumpkin housing from the axel tube to the cover plate. I kept the tires and put a ten bolt rear end with 267 gears and put a four speed Muncie transmission in.with those gears you could drop it back into first gear at fifty miles an hour and burn the tires off.the speedometer was no longer accurate but there wasn't a day I didn't do well over one hundred with those gouged out tires. My wife made me park it when our second kid was born along with my street bikes. It is still sitting at my old place where my daughter lives now. The poor thing needs a little paint and upholstery and it's probably time to change those tires.

Hey Travis, in that case, there are 2 easy options - use the GSXR wheel with the GSXF caliper/mount that allows for a top mounting, or go for the YFZ 600 R (Thundercat) option which keeps the FJ caliper, torque arm and keeps the top mounting.

Two easy-peasy-lemon-squeezy ways to a 17" back wheel and good, modern-sized radial tyres

I haven't checked how deep it goes yet. Didn't want to hack into it while still using it 

Tyre code on wheel is
DOT   XE  KX     E478      4916

not happy with the date as it is dec 2016 manufactured and it was only bought March 2019

I figured slicing away the flap of rubber didn't really make the tire any worse than it was. I never trusted that tire over a hundred again but I did continue to ride it until I wore the back tire out. Here are pictures of what it looked like when I pulled it off,inside and outside. No signs of the slice from the inside.The code on my tire is DOT XE KX E478 3717. Forty weeks newer than yours. The new split I have on my rear tire is different. It started out at about 3/16" long. In the name of science I decided to ride it to Carson city and back.It wasnt a twisty ride but I took it up to about 115. The split seemed to widen a bit and grew in length to 5/16".It was still only leaking a small bubble every few seconds. I found the hole when I was readjusting the chain tensioners to realign my wheel that was off center. It had caused my chicken strips to be wavy. Once again in the name of science I rode it up and down the twisty road to virginia city three times without stopping ,about fifty miles in all of hard corners and got the tire very hot but never went over 85. When I rechecked the tire (I also checked it several times during the ride)I found no changes to the split. My chicken strips went back to a straight crisp line though. This rear tire split though much smaller than the one on the front seems to be a prelude to disaster . It will be interesting to see what it looks like on the inside. I know it goes all the way through.

I think both of your DOTs say it came from the same factory, but this info ahould be checked. I suggest you both write to Pirelli.
