good idea, Im on first name terms with the Tyre bloke now. (I think hes gettting a bit annoyed with me, )

 

hey, this guy could end up being your new best friend soon

of course, you really only want to swap tires long enough to test. you wouldn't want the treads to be backwards if it gets wet out

 

different tires, and especially different pressures will cause this. Because You are running two types of tires in the rear, overinflate one by about 2 pounds and see if it helps or makes it worse. If it makes it worse go back to 32 and inflate the other by two pounds. Through trial and error you will get it to work. But next time, purchase matching tires.

 

i had this same problem...

1: different tread pattern
2: different tread thickness (one worn more than the other)
3: tire pressure

the driving tires (the rear for the S2000) need to be exact. that means you might need to buy 2 new tires for the rear to fix this problem.

 

money is on the different tires...
