Stock F1 EMT's are at 11k miles, I might get a few more thousand out of them (although they are at the wear bars). I have rotated 3 times so far, and attribute this to the above average wear I have attained from these tires (this includes about 200 minutes of track time at VIR).
After reading the how to widen your stock wheels thread:
And then looking at the pics that Wildwhl, and Dreamin posted
I am seriously considering going with the Goodyear F1 GS-D3's, in a 245/45YR18 Front / 245/40YR18 Rear configuration. I love the way the 275's look, and would be willing to give up a little bit of rear turnin stiffness (based on using the stock rim @ 8.5" with a 275, let me know if I'm offbase here). I also love the very agressive tread pattern on the GS-D3's. It just looks so serious, for lack of a better word.
I know this will introduce some overstear into the car's neutral handling.
I found a tire calculator that put the front tires at 26.68" diameter vs. a 26.66 rear diameter, so it looks good from that perspective.
My main concerns comes from the change in hadnling, and the basic inability to rotate the tires in this config. The front to back is not compatible, due to size, and the right left would also not be compatible due to the tread direction.
1) Does anyone have any advice or experience with this type of application (perhaps covertte owners can chime in, as this would be close to their config). Will I chew through tires on the V if I don't rotate them?
2) Should I consider a non direction tread tire, so I can swap right to left, or will this give me little to no added tire life benefit?
3) How much will this upset the car's handling? I can live with a bit of overstear, as long as it is predictable, and doesn't trash the car's overall handling
4) Will going to 275's in the rear help or hurt the wheel hop issue?
5) Is this a bad idea?
6) Would I need any alignment changes if I went this way?
I've never had a high-po car before so tire shopping for one is new to me (is it obvious )
Thanks in advance,
