Can anyone tell me what the width of a mounted Michelin PR4 rear tire is? I'm looking at the 160/60-17 and 180/55-17 series. I'd like to try a set of these tires.
My Continental RA/2 170/60-17 measures 7" (178mm) wide and clears the chain by about 1/4". Michelin doesn't seem to make a 170 series PR4.

I am also interested in the width as I was planning a set of pr4's for my 17" rear swap.
Perhaps the width of the 180 tire and what width rim it is mounted on would be better? It changes a little bit if you're on a 5.0 or a 5.5 rim....
Good point. I''ve got a 5.5" wide rim.
I have not used one as of yet.
I believe that I saw a few that have been installed on members bikes at the Central Rally. Dan McCoy (giantkiller) comes to mind as having PR4's installed. No complaints of being too wide that I heard.

Since this subject has popped up a few times, maybe we can get the actual measured width of many tire brands and models. This will help others considering changing tire brands and or model to know if they need to get a 170 or a 180 wide tire. We have the first contribution a 170 wide Continental Road Attack. I will contribute my tire width today.

The Dennis Kirk site looks good for getting size info but they don't have it on all tires. I was hoping to see what the Dunlop Q2/3 width was. The Q2 in 180 wide rubbed the chain, by the time I replaced it the chain had removed about 1/8" to 3/16" off the edge. The 170 rear cleared the chain.
The Continental Motion (code for good price but mediocre mileage) 180/55-17 on a 5.5" wheel measured 7", same as the Conti RA/2 in a 170. The 180 wide PR3 is almost 1/2" wider putting the edge almost 1/4" closer to the chain. I don't have that much room, so now I know I need the 170 wide when I am ready to try them out.

Right: I looked for quite a while for the PR4 width but no luck. I did see some forum postings indicating the that the PR4 is narrower than the PR3 but no actual measurement. I have a 180 PR3 on 2008 R6 5.5 inch wheel (and 2008 R1 swingarm) with no clearance issues.

I can't tell you the exact width, but I put 170/60 x17 pr4's on my 4 1/2 rim and it fits in standard swing arm with about 1/2 inch to spare on either side of the tyre.
Sorry, I'm currently out of town so I can not measure my 180/55-17 PR-4 tire on my 5.5" rim.
Stay tuned, I'm sure others will chime in.....
I'm smokin 5 racks of ribs right now at my moms.6 hrs have 3 mor hrs. But will try and measure 180 pr4 on5.5 when I get home tonight.

First you break them, now you are smoking them... What won't you do? :shok:
180-55-17 PR 3 on 5.5 rim at 40psi measures 183mm (182.60 mm) max width. As best I can measure with a caliper. Rear wheel is centered in the swing arm and I have 5mm (5.24mm) clearance between tire edge and my chain rivet head. No sign of any tire wear or side wall "milling".
That's all I can conturibute on the subject.

My 180/55-17 Conti-Motion measures 6-15/16 inches mounted on a 5.5" wheel. At 40psi
The Michelin Pilot-Road 2 180/55-17 that I took off measures 7-1/8 inches unmounted.
I used a straightedge on either side, and measured between them

Michelin doesn't seem to make a 170 series PR4.

They make a 170/60-17 in the GT tire.

This is quite a timely subject as I have been thinking about this as I'm due for new tyres soon. With only around 5-7mm chain clearance with the current 180/55 tyre mounted, it would be bit late to bring home a nice shiny new Pirelli Angel for example and find it rubs the chain. In that case it would be worth just dropping back to a 170, don't lose that much width.

Ray, a Pirelli Angel 180 wil NOT worry your chain. I've run both the Angel and PR4 180's with no clearance problems. My PR4 has about 5-6mm chain clearance, about the same as the Angel.
Regards, Pete. :good2:
I have two PR 4's. One on a 5.5" FZ1 wheel and one on a 5.5" GTS wheel Both measure 6 "15/16ths. The variance between the two is less than 1/16th. Both have been manufactured within the last calendar year.
Pirelli Angel GT, 180-55-17, mounted on 5.5" wheel is a whisker under 7 1/4" wide.

That sounds like the tire I want. What series? 180? 170?
Thanks
The I'm running pr4 180. Excellent tire. Pr4 180 is slightly narrower than the pr3 180

Mark, the 180 will fit. At 7" wide you will have about 1/4" clearance on the chain. So you run either a 170 or a 180.
Thanks, I want the widest Michelin PR4 tire that I can fit, so if the 180 is 7" , that's the one I'm going to get. 7-1/4" appears to be the widest tire that would fit on my set up and would leave me with barely 1/8" clearance.
Pr4 180 is just under 7"
Sorry, I am using a 180/55/17 on both.

Thanks ! 180 is the one then. Now I need to ware out this set of Conti's. Love the RA2's, but no tread in the center of the rear tire makes it hard to tell when it's done... then one day the cords start showing through.
Thanks Pete and Derek, good to know
A 170/60 pr3 fitted to a 4 1/2 inch rim is about 165mm or 6 1/2 inches wide. Plenty of room left.

I loved them too, but over 4 consecutive sets of them I'm sure I've thrown away 10's of 1000's of miles worth of tread by replacing them before trips for just the reason you mention, no idea how much life is left and not wanting to run out of tyre mid trip.
This time round I have a set of Z8's and next I'll try the PR4's. By all accounts the Michelins perform as well as the others but last way longer.

For further PR4 application reference, I run a 160/60-17 on a 5" wide rim. It measures 6 -5/16" at 41 psi. I have about 1/2" clearance between the chain and the tire.

Seems like you could run a 170 wide tire...

Hi Mark,
Yes I have run a 170 Avon in the past and it was fine. I think the 160 looks fine and turns a bit quicker with the narrower tire. I run a penske raised to its max with forks raised about 3/8" above the triple.

No worries then, as long as you are happy with your set up. After all, that is what we are all trying to do with our bikes. Make them fit us like a deer skin glove.
