What is the difference between...
What is the difference between the Goodyear Supercar's that are on my Z51 and the regular F1's that come on the standard suspension cars? Thanks.

The regular runflats have 10/32 tread depth to start with and a wear rating of 300. The Supercars have 9/32 to start with and are rated at 220 for wear. Both are speed rated to (Y) which means 186+, which is the highest speed rating available. Supercars are softer to stick better, but wear out faster because of this....a standard tradeoff of performance for treadwear.

.....but, considering how "BAD" the economy is supposed to be, I'm amazed at how many people I see who do seem to have $ falling out of everywhere!
