I have a rear tyre: 170-17-55 is it the right size, i thought 180-17-55 was the right size, on the manual i didnt see any reference to this . Thanks | ||

They are the stock rims that were on the bike when i bought it, it's a 2002 X1, but i have a pair of PM for when tyres wear out. | ||

If you have the service manual for your '02 it should be listed under "Tire Specifications, General". I have a '99 and the '99/00 manual says cast stock rims take a 170/60/ ZR17 rear. I have a 180 on mine and it clears. | ||

with pm wheels you can run a 190 depending on brand I did with no issues on my S1 | ||

Depends how you want it to handle. The CORRECT size for castalloy wheels is 170. The CORRECT size for PM wheels is 180. You can go one-up on either wheel...but then you pinch the tire, taking a round profile and making it peaky. Your right/left transitions will no longer be as smooth, and your on-center handling (i.e. highway cruising) will be dodgy because you'll be "falling" off the pointy center section more easily than if you had a correct size tire on there, with the resulting correct curved profile. | ||

Only thing I would add to Ratbuell's post is that you also have to be mindful of sidewall ratio. Stock is 170 55, I have a 190 50 on a set of PMs, 190 55 would have too high of a profile. | ||

Thanks for the info, i'll be changing the wheels son, as i have a país of PM rims and i'll go for a softer compondrá tyres, the bridgestone but 21 sport touring are way to hard dure they last a lot but dont have the grip of a metzeler m7 | ||

IIRC, the PM rear wheels are 5.5 inches wide while the cast rear wheels are 5 inches wide, which is the reason for the difference in recommended tire sizes. | ||

Get michelin PR4's. You can thank me later. They're awesome tires, I got 9800 miles out of my PR2 (earlier generation) on my S2's rear. Just put on a PR4. Hard center, sticky shoulders, excellent wet siping, beautiful transitional behavior. My S2 actually got a PR4-GT in a 160 - slightly beveled rain sipes for more even wear / no feathering, and heavy duty sidewalls for sport-touring. Put a little over 1k miles on it blasting through WV last weekend - pure bliss, no chicken strips, on a fully-loaded (camping gear and all) 20 year old motorcycle. | ||

Where i live there is hardly any rain, and full of twisties, with good and bad tarmac, i hadmichelin before, but is moré a flat tyre, not as round as metzeler, from my experience with the Ulysses i had. |
