Speed rating?

[Bristol350z]

I need to buy new tyres all round for my JDM 350z. Ive got 18inch rays GT alloys and know that i need 225/45 R18 tyres, But theres different speed ratings and i was wondering if anyone knew which speed rating i should use?! Any help would be great! Cheers.

How fast you planning on going?

Well as fast as the law lets me . I was looking on black circles website and thats when i noticed theve got different speed settings so wondered what i needed! Im looking to sell the car soon anyway, But the tyres definitly need changing while i still own it.

Tip of the day - go see what speed rating yor current tyres are

Good tip! . I just went and checked and ive got bridgestone potenza tyres on at the moment which are 91W, So guess il stick with that rating! Cheers.

Only at the front, the rears need 245/45/18. Putting the same size all round is a recipe for chronic oversteer and seriously not recommended

Well that was lucky, as i was literally just about to pay for some online! You may of just saved my life .

My fronts are 91W, and i just checked my rears and there 96W, does this matter?

Dont get Potenza 040's! Miles better tyres out there.
