Yeah I'd think you'd be ok. The sport wheels are 17mm further in than the base wheels with 245/40's and obviously no rubbing stock.

Inexpensive Summer tires in my desired size:
- Sumitomo HTR Z III = $600
- BFGoodrich g-Force Sport COMP-2 = $660
- Dunlop Direzza DZ102 = $750
- Hankook Ventus V12 = $800

Any thoughts on the above?

What about whatever they're calling the new Star Specs or a set of Azenis?

HTR over v12 any day. Cheaper and better performer. Not sure about the other 2. The HTR is a good summer but that's it. Its not a track, autox or drag tire so the other 2 might be better.

The V12 doesn't really do anything well. It's a "good enough" tire.

Ahhhhh... this is the feedback i'm looking for. Good to know the cheapest in my size are pretty decent.

dude save your money, you will chunk those tires if you drive it in any reasonable pace

No issues here, but I have 255/285 so more contact patch.

also running the bfgoodrich comp 2 sports. I did another review on them here awhile ago if you wish to read it. Just search for that tire. Had it at an autox track. Worked pretty darn well and a good amount of feedback. Youll certainly know when too much is too much. But you can take those corners pretty hard. A buddy of mine is running the same tires on his sport model. He likes them a lot too. They are a little softer in the ride and dont hop so much. I like that about them.

Contact patch is a function of the car's weight at each corner, not the tire size. When you change the dimensions of the tire, it changes the *shape* of the contact patch, but the magnitude of the contact patch (square inches of area) remains the same. A wider tire has a wider contact patch, but also a shorter one.

So a 155 tire and a 320 tire both 26" in diameter have the same contact patch in square inches? I don't think so.

Think so. the 320 will just have a really wide skinny contact patch and the 155 will have a long narrow contact patch. Now if you go down in PSI with the same weight you can increase the total size of the patch.

I drive the car to the limit of adhesion for HPDE. And you say the HTR tires will chunk up huh?
