This is for track and around town. I have seen D Group (advanced) track drivers with 255/40/19 front and 285/40/19 rear. I have not seen any wider than 245 front and 275 rear for 20" rims. Anyone else have input on this?

Also, any thoughts on additional negative camber on my Cayman S without PASM . Toe in? Adjust the shocks. Anything to stop the everyday driver, understeer, that is engineered into the setup of my stock 718 S?

I have bad corner wear on my Pilot Sport 4S tires. I just had to replace the fronts with only two days at Laguna Seca and two days at Sonoma. No, I am not the smoothest driver on the planet but I would guess I am in the middle of B group drivers in that respect. Essentially, I am an average intermediate HPDE driver.

I contacted Michelin about my 4S tire wear and they said "4S tires are not recommended for track use." TireRack doesn't recommend them for track use either. Michelin rep said, “Extreme corner wear is a problem with these tires when used for autocross or other high performance driving, including track days."

I talked to a few guys at Sonoma this weekend who were running 4S tires and they all kind of copped to the same dirty little secret; that they wear out extremely fast.

Do you want a street tire for the track? Or a track tire for the street?

If you plan to do a fair number of track days, it might be worth considering a dedicated set of track wheels, either in 18" or 19", where the tires themselves tend to be less expensive.

I have Cup2s mounted on the OE Carerra S 20" wheels
245/35 front
285/35 rear

They are not ideal fitment especially the fronts but they worked well before my 18" track wheels were delivered.

I think 245 or 255 on an 8.5" wide rim is fine. I have 245 Cup 2 N1s on 8.5" and they are great.

I'd say 285 is at the limit on a 10" rim but I have seen some people mount 295 Cup 2s but they probably don't work as well as with a 11" rim.

Will 295 tires fit on Carrera Sport Wheels?

They’ll fit quite nicely as a matter of fact. Did our OP’s 'GT4' 295-30-20 rears but substituted an upgrade to the GT4’s with 255-35-20 in front. OE 982/718 Carrera S wheels with Michelin Pilot Super Sport 4Ss. Curious that specifications supplied by Michelin indicate identical OA diameters...

Did the 255-35-20 and 295-30-20 combination on most recent fitment.

Very pleased.

I have the 20" Carrera wheels and have put on 245/275 tires they fit perfect and have NO issues at all. They fit even better than the 235/265 the sidewalls are straighter

I’ve also done this, added benefit is that the Speedo is nigh bang on accurate...

Any issues develop since your post? looking to do the exact same setup.

Sorry for the long delay, I have had not issues at all, I plan on lowering the car shortly and will update when I finish that
