Bristol350z Posted August 14, 2011 Share Posted August 14, 2011 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!

Bristol350z Posted August 14, 2011 Author Share Posted August 14, 2011 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. Quote Link to comment Share on other sites More sharing options...
Lexx Posted August 14, 2011 Share Posted August 14, 2011 Tip of the day - go see what speed rating yor current tyres are Quote Link to comment Share on other sites More sharing options...
Bristol350z Posted August 14, 2011 Author Share Posted August 14, 2011 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. Quote Link to comment Share on other sites More sharing options...
Ekona Posted August 14, 2011 Share Posted August 14, 2011 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, 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 Quote Link to comment Share on other sites More sharing options...
