I have 265/35/18 & 295/35/18 Bf Goodrich KDW's on 18/9 & 18/10 FR 500's. Since I can no longer rotate my tires, and they also cost so much, I have been trying to make sure I check my tire pressure often. My question is how much pressure is the correct amount to run on a street car so I can get a long life out of them. I love the way the rims and tires set my car off, but unless your rich they take alot of the fun factor away because I can no longer afford to do burnouts whenever I feel like it. The trade off is that now I can take corners alot more aggressive since these tires stick a hundred times better than the crappy 245/45/17's I had on the stockers.
