I just got my new tires I ordered yesterday and I was just wondering what kind of tires/sizes you have on your Z's. What kind of tires have you tried before and how well did they preform?

My new tires (rear only) are Yokohama S.Drive (255/35R/18 Y).

Also while we are on the topic, I am going to be getting new rims and what width of a rim do I want (in inches) for 255 tires?

as for the rim size you need if you read the spec from the tire manufacturer
they will give you a minimum and maximum safe rim width for the tire size you have selected. If you think that in the future you may want to go with a wider tire then pick a rim width near or the at the maximum recomended width.

you're 255's should fit a 9-10" wide wheel
