I have an 08 rim and am currently on stock sized tires. Unfortunately one my my rears snagged a nail in a 'non-repairable' zone.. so I am forced to replace the rears and I want to go with the Michelin PSS.

I know people are upsizing to 245/275 and lowering the profile, but I am wondering if anyone is running the PSS on stock sizes. The reason I would stick with stock is 1) to retain my current set of fronts 2) prices for the stock sizes are cheaper.

Or am I missing out on the upsizing route? If so, can I run 275/35 with my stock fronts until they wear out? Is that 'too' staggered?

The correct upsize on stock rear wheels is 275/30/19, although when I had stock wheels I ran 285/30/19 in back with great success. As far as using the stock fronts (225/40/19) with up sized rears, read this thread:

I had 2 sets of them on stock. Size. A truly amazing tire. The best all around tire you can put on an ISF. I currently have AD)8Rs because I do a lot of track time. I am trading wet grip and refinement for ultimate dry grip. If you are not on the track the PSS is the BEST......period. Anything else is just cutting cost or adding tread wear and trading for grip.

My opinion is that the 245/275 combo is not the right diameter and looks odd. Even thought he difference in diameter is very mild I can tell and it bothers me. Just looks odd. To each is own, but this is why I maintained oem sizes until I could up size to the correct diameters and sizes 255/295 on appropriately size wheels with the correct widths to maintain the correct sidewall tension to maintain steering response and over all fell.

I will definitely agree with you Tammer. The only negative to this is that the OP is wanting to use the stock wheels, which for him would be 19 x 8.0/9.0. Now I know few have gone to the 245/285, and it works great. Added tread without sacrificing much of anything in terms of performance. I also believe that PSS does not come in 285/30, so that is a big detractor right there.

For the OP, for your stock wheels, I found that many owners have upsized to a 245/35 and 275/30 combo. While it's not exactly the same specs in terms of diameter, revs/mile, and the such to the stock tire setup, it is very well received in terms of an added driving feel. If you want the maximum 285/30 on a 9.0 wheel, I'd look at other brands, as Michelin doesn't have it in their PSS offering.

I did 245/255 PSS on my IS-F.

I have no complaints.

I am on 255F and 275R PSS with the 2012+ wheels. It works just fine except in the cold we've been having here in Atlanta. The front end chatters on sharp turns at parking lot speeds because the tire's grip is low when it is cold outside. Above 45F and they're all around fantastic.

Lance, not really a good idea to be driving on summer tires in the extreme cold:

No argument here. I was seriously thinking about a set of AS3s in stock sizes for the cold months on my original wheels.

The same as Jum3, I want to put PSS on 08 wheels and have some questions:

Option 1 - put OEM size, but I guess understeer still would be a problem - now I'm running on Potenza S001 OEM sizes and car understeers too much
Option 2 - go for 245/275 set - will PSS fit?? I know some guys here are running this setup, but not sure with PSS. Is PSS wider than equivalent tyre of different manufacturer? E.g. PS2 were wider than 050A of the same size. Plus 245 on 8J rim seams too much - how does tyre behave?
Option 3 - step up only to 235/40 and 265/35 - both wheels size goes up around 1% (8mm diameter), so I guess it should fit - anybody using this setup?

Option 2, with the 245/275 upsizing was introduced with the PSS in this forum. Ultimately, I went with this option..

The 25-30k miles users were getting out of these tires are significantly better than any of the other cars I was driving. So I just bit the cost of the extra fronts.

Thanks for quick answer!
How does front behave? It's pretty tight for 245 tyre, right? Not too much 'bubble'?
Did you track your car with this setup?
Any change to the geometry or standard?

^^^^I'm running RCF wheels (9s and 10s) on my ISF. 255/35/19 and 295/30/19. Backs needed fender rolling, but only because of the change in offset from the stock wheel. fronts only had a modest offset change, and there is plenty of room.

Below is before and after pics taken 7 years apart. Stock wheels and tires versus as described above.

RCF wheels look great on the ISF, and the bigger tire size makes the car look meaner

Guys, we're talking here about OEM IS-F wheels.

What about Option 3 - step up only to 235/40 and 265/35. Anybody using this setup?

Didn't even think about 265. Good idea
