Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

16 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Car going into the shop on Friday and the dealer is out of PS in 285 sizes. (Told me all Porsche dealers are) and to go to Tirerack or similar. I found 285/35/18 and would like to replace my 265's in the back. Dealer said would work just fine and go for it. What do you think? Trying to order them tonight....

POST 3Original post

285 will fit on 18x10. 265 also fit on 18x10. You can get 285.

POST 4 / ORIGINAL POSTEROriginal post

rim size is 18x9.5, which acording to dealer will work just fine

POST 5Original post

should be fine. side wall might look bulgy though (just a looks thing)

POST 6Original post

9.5? What rim is it? Haven't heard of any of the rims being 9.5". The side of your rim should be stamped with the offset and rim size next to the valve. You might want to check it. FYI....the correct size tire (Porsche rec'd) for the rear is either 265/35/18 or 286/30/18 (not 35).

POST 7Original post

I put TOYO T-1S 285/35-18 on ththe rear, thinking that a .5" overall increase in diameter would not be that bad. WRONG. On top of the car looking like a dragster ( taller sidewall) the rear end was realy squirmy. I would do some tight S-turns and the rear end would be slow to catch up with the rest of the car. I even tried the tires at 51 psi, better but not good. The car was scary above 70 mph, do tthe rear not feeling planted. Dealer took the tires back and I have SO 2's on now; night and day difference. Just my account, PS tire may have a much stiffer sidewall, but the overall diameter is still increasing.

POST 8Original post

Just get the proper size in S02-As from tirerack. They are Porsche rated N3 and or the same tires that come on the Turbo S. Approx. same price as PS and you will be pleseantly surprised by the performance ans feel.

POST 9 / ORIGINAL POSTEROriginal post

The reason i say 9.5, is the previous owner had demolished the two right rims in a pot hole. Replacement rims were shown on the repair receipt as 18x9.5. I have 265/35 on the back now.... i will inquire regarding the 285/30 tire.. I am only in need of replacing the rears, as the fronts are still in good shape. I would of liked to try bridgestone or toya but no need for 4 at the moment...

POST 10Original post

Is it a Genuiine Porsche rim or aftermarket? Did you check the stamp on the wheel to verify?

POST 11 / ORIGINAL POSTEROriginal post

Believe it is Porsche, but am at work right now, and not with the car to check the rim....

POST 12Original post

Your backend will be slightly higher with the 285/35's. Don't know what is on the front but if stock, the back wheels will look larger.

POST 13Original post

On my old '99 I went from 265/35 to 285/30 with no problems at all (the factory did the same thing I think in '02). The 265's always looked too small, like they were stretched to fit. A side benefit is that it'll now look like the front as far as how the tire sticks out a little from the rim and give you some protection against curb rash.

POST 14Original post

I don't think it is recommended to mismatch tire especially on a C4. What is on the front?

POST 15 / ORIGINAL POSTEROriginal post

That is why i am sticking with the PS tire. That is what is on the front as well. But I just cant decide if just the rears or all four with SO2's. Trouble is, much of it is on back order for the ps...

POST 16Original post

Don't mix tires. If you really have to, make sure they are N marked.
