After having really good luck with a set of General's Altimax HP on my Pontiac Grand Prix, I decided to try their GMAX AS3's on my Pontiac G8 GT. I cant tell you how disappointed I am with this tire. NOISE! I have full exhaust from the manifolds back and while crusing down the highway at 70-75 the tires were as loud as the exhaust note. Treadware was disgusting.(Now in the interest of full disclosure I only rotated the tires twice in 18k miles) I think the warranty on the tire was 40k? and all I got was a shade over 18k. I just replaced them with a set of Michelin Pilot Sport A/S Plus' and when I looked the tires over after they have been dismounted, you can see the belts had shifted which explained the noise and the pulling to one side. I will say however that the tires had excellent wet traction/handling and better than average dry traction/handling. Overall im very disappointed in my experience with these tires and I guess the cliche you get what you pay for rings true here.
