My P-Zero fronts are just about done at 50,000. The rears are better.
Like the OP, I am going to buy new tires soon. They will be summer tires. The Pirellis have been satisfactory, wet and dry, but a bit noisy.
There are Firestones for a lot less money. Any comments on these or other less expensive summer tires?
I am running the stock sizes. On my Z28, I had the Firestone WIDE OVAL Indy 500 summer tire. I had no problem at all with them. They were smooth riding and quiet and wore very well. I'm just curious about the new version of the Indy's but they're so new that there's no reviews yet on Tire Rack. And it is a better looking tire than the older Wide Oval Indy.
