I've seen this topic covered a lot on here but I think my question is slightly different. I like fat tires (like everyone else does) but I'm unwilling to sacrifice any performance for it. In your opinion what is the best size tire for performance on a 15x7 wheel? All other things being equal I would lean towards the wider tire until the point where it impedes performance. I do also want to make sure that I have a tall enough sidewall that the tire looks right. I currently have two centerline wheels (I'm guessing 15x7) in the front with 235 60 15 tires and two fake centerline wheels (i'm guessing 15x9/9.5) in the back running 275 60 15 tires. The rear non-legit wheels are pretty beat up. One of the rims is losing air pretty dramatically and it is a hassle and probably unsafe inflating the tire every morning that I want to drive the car. I bought a set of pretty nice z28 wheels that are 15x7. I will likely have the rear wheels widened in the future but I still have a few months of driving before I put car away for the winter so I need to buy tires now. If it matters, I'm running 430hp/450 torque small block with a 4 speed transmission, factory suspension thus far. I do not see any evidence that the car was raised or lowered. Here are pictures of my new wheels and what I have now.
