I did not upsize the fronts since they are staggered. Did the same on all my Porsches. Not noticeable handling issues, at least not to me. The biggest difference to me is the better hookup, less wheel slip.

 

OK thanks... I have been contemplating moving up to the 305 and leaving the fronts as is.

It would be best to stick with the 255 OEM width in front unless you go to a wider wheel. A 9" wide rim is not recommended for a 265 tire.

 

Just ordered Pilot Sport Cup 2 in stock size. Can't wait to try them out.

 

I decided I'm going to try the 305's (Pirelli P Zero's) instead of the stock 295's while I'm waiting for the fronts to wear out. They are also a little less expensive to my surprise. I'll then go with the PSS's for my next set.

 

OK, thanks..
Lawrence.

 

Which size? R or v6?

 

I meant rears in stock size, probably going with 265 fronts. It's an R.

 

My apologies, I misspoke. The 9" wheels are within spec for a 265 wide tire.

 

I'd like to try the PSS's based on the reviews but the dealer installed a brand new set of P Zero's on my CPO F-type right before I took delivery so I guess I'll have to wait awhile.

After waiting several months, my tire guy finally got in a pair of 305 PSSs (305/30-20). He ordered 6, got 2. After 10k miles not yet needing a change, but at least i'll have them available in a couple of months when I need to swap them out. They look massive. Might need to remove the spacers. (anyone have 15mm spacers with the 305s and lowered?) Per spec they have a 12.3" section width, but my 295s only measure a hair over 11.0" instead of the 11.9" as specified. Likely there is some deviation because the 295 is on the rim, but I don't see it varying that much.

 

Thank you sir for the update. Congrats on obtaining the new tires. Let me know if you have any issues, because I was considering ordering them earlier in the week when everyone said they would fit on stock wheels without an issue, but if you think they may not fit let me know when you try.

Thank you

 

Guaranteed to fit if you don't have the spacers AND a lowering kit. With either individually there won't be a problem. I'll get this sorted out the same way I first learned to race. Take it to 110% and then back off 9.5%. (I subsequently found much better ways to learn to be fast).I may just remove one of the rear springs to observe the full travel of the rear wheel/tire.Place your order now. You'll have lots of time to cancel it if need be.

 

awesome. thank you. Yeah no lowering here or spacers. Will order tomorrow. Hope not too long to come in..
