Rear tires are almost dead.. sizing?
So my rears are almost done, fronts are 40-50%. I'm thinking of getting wider tires in the rear.. would it be a bad idea to go 285/35/18? or should I go 275/35/18? Thanks.

285/35/19s are to tall, for the rear its going to be either a 285/30/19 @25.8" tall or the 275/35/19 at 26.6" tall. A 285/35/19 is almost 27" tall...I am running a 255/45/19 front and 285/30/19 rear (M3 GTS sizes) and love the look.
Also you didn't mention what wheel you are running. Is it the 220s or the 359s? Dave

Run 275-40's on the rear. If you like to look ahead, I would spring for the 285-30 rear, and when your fronts are done, go for the 255-35.
However, if you have PS2's, it may be hard to source them as they have been replaced by the PSS.

Hmm. I was going to go with 255's int he future my only concern was with regard to the differential of running 245s front and 285s rear until the fronts wear out. Also would it be a bad idea to combo PSS in the rear with the PS2's in the front until they wear out?

For street use, the difference between 285 and 245 will be miniscule. Again, pushing at an autocross or track is when you will really begin to see the differences.

Is the 285 too wide for a wheel with a 9.5" width?

You can run a 285-35-18 tire just fine on a 9.5" wide wheel. The minimum required width based on the tire specifications is 9.5" wide wheel. I made a mistake in my first post, I thought you had 19's so I told you to use 285-30 tires. Please disregard my mistake, for your 18's you will need to run 285-35-18 and 255-40-18 (for your future fronts).

Every tire is different. If there is a tire you have in mind, let me know and I will get the specs for you. However PSC is not a normal conventional street tire.

So a good rule of thumb is a 285 street tire will fit on a 9.5" wheel and r-comps all bets are off? Thanks.

sorry to hijack the thread but I was also looking at putting wider tires for my rears maybe a 285-35-18? The problem is I am running 12mm spacers in the rear with the oem 219 wheels (18"). Anyone know if they will fit?

But yes, you can pretty much say most if not all street tires that are 285-30-18 will fit a 18x9.5" wheel.

You cannot run 285-30-18 tires on your stock 18's with a 12mm spacer. It will not fit without very slight rubbing, however this is greatly dependent on the type of tire you use and what the alignment settings are.

I plan on running PSS with all factory alignment settings. Think it will work?
