What Tires come stock?
6 S55s) Some are R rated and some ZR rated. Different brands as well, could someone help me as the reasoning for this as well as the differences betwween the R and ZR. The sales man told me the ZR are rated for faster speeds but the R rated that are on the car that I selected ride better, is he giveing me a line? Should I push for the tiers to be switched and get the ZR on the car that I am getting? I have alawys had ZR rated tires on my past cars. I thank anyone for any help as the paper work will be finished today and will be delivered tomorrow.




You need to look at the entire designation to fet your answer. A 265 45 R18 Y101 tire is Y rated with a load handling index of 101.
If the dealer has both ask to drive cars with both types on see if either gives a better ride or handling ?
Sorry all I know is that Z tyres are rated for over 150mph,
WR are rated to 169 mph, ZR seems to be the new rating to replace Z "Speed Category "ZR" For vehicles with a speed capability over 240 Km/h "
