The car behaves just plain ugly - When I accelerate it goes left and when deccelerate it goes right. I can't imagine why they don't put big warning on them 'not suitable for sports cars'. I don't know if anybody else has similar experience with tires with assymetric thread. My observation is that S2k can't have tires with assymetric thread. Another $800 wasted. Alignment and everything checked.

 

This is generally a result of uneven tire pressures. Did you check and confirm the pressures? It would comical to think that you've just trashed a complete line of tires solely because you had inappropiate and uneven tire pressures.

Aftermarket rims? Proper lugnuts? Centering rings in place? Didn't put front rims on the rear and rear rims on the front?

 

 

I don't think the tread is your problem. Anything that xviper mentioned could cause what you're describing.

As for a warning as to not using them on a sports car, there IS one...

M+S.

 

This is a VERY good point. If you try to drive the car with M&S tires on dry roads like you would with high performance summer tires, you may be far exceeding the capabilities of such tires. Any number of peculiar driving characteristics can ensue.

 

But maybe he takes his S2000 through a lot of mud & snow

(Well, we do up here, but we have dedicated winter tires )

 

+99 on checking your tire pressure. Most tire shops forget to check the pressure after they put in 50psi to seat the beads.

 

i have those on another car. they tramline like crazy on the freeway, but even out after you put a couple thousand miles on em. good tires in the wet, but i wont buy again.

 

I've had these tires on my old Integra and now my s2000 I feel that they handle with decent predictability... the problem is that you can't get a 245 rear setup. Good for adverse conditions, bad for performance.

but it'll be spring soon and I can go back to my s02's.

 

According to Pirelli's website, the Assymetrico doesn't come in a M & S tire - only the P-Zero Nero. In either case, you are correct. They don't come in the proper size for our rear rims, assuming he's using the OEM rims.
