I just put these tires on my 89 N/A with some mods, approx 225hp.

I'll let you know in a few weeks how they handle on fast mtn. roads. And when it rains again, I'll go test them out for handling and traction.

On side of tire:
Treadwear: 500
Traction: AA
Temperature: A
Speed Rating: VR

America's Tire Store....drop off car, pick up an hour later. Ready to go !!

Those were the tires on my last supra. Great in the rain. Not amazing for launching though...

tell u right now. the lower the treadwear number the better the tire
