OK, I got a second set of OEM Double Spoke 2's, made a snow set of the 4 7.5's, and a street/track set of the 8.5's (well, trying to).
The new wheels came with some Continental Sport Contacts in 245/45/17 which are practically new. My old 8.5's has Kumho Ecxta MX's in 245/40/17 and they are down to the point where there is almost no tread left. They were in the rear of the car for 5 track events and 12,000 miles. The Kumhos are way wider than the Continentals. The Kumhos are not on the wheels right now, the continentals are. I test fitted a continentals on the front of the car with the 8.5's, it BARELY misses the strut inside, seems to miss the fender lip OK (i hope).
My problem is that I was planning on using up the Kumho's in the front on my first track day of the season, as I can't afford new tires now. But I don't think they will fit! I wanted to finish them off by wearing out the shoulders. I wore through the shoulders on the old 225 Kumho's down to the wires, thus the need for front tires.
I also have the 225/45/17 Continentals that came with the new set of wheels, but I was wanting more grip up front even with the Kumho's, so using these Conti's up front would defeat the purpose i think.
Would I gain anything by using the 225/45/17's Conti's on the 8.5" wheel in the front? Or should I use the 245's in the front? and use the old kumhos in the rear and hope I don't blow a tire on the 4 hour drive to the track?
Any help/opinions appreciated!
