Best tire to run on 15" rims

[todd lorber]

Could someone here please help me out with actual tire measurements? I plan on putting 195 60 15's on the front of my roadster and either 205 60 15's or 205 55 15's on the rear. The tire size calculators on line show diameter of a 205 60 15 at 24.7" but the ones on my Z, which only have a couple thousand miles on them, measure out just below 24" in diameter. I know that 3/8" radius difference doesn't sound like much, but I will be cutting/recontouring my rear fenders and I wanted to be as precise as possible.

Any help on actual measurements will be greatly appreciated.

You can’t compare static measurements and actual on a car , if you want to compare you need to look at both n same condition

Even a spare set of 205 60 15's that I have that are mounted on rims but not on a car, measure very close to 24" in diameter. Not the 24.7" that the calculator shows.

I have 195-60/15, and 205-60/15 on my car, with panasports, and I can put my fingers between the rear tire, and fenderwell. I'm not sure the offset, but those sizes seem fairly common. I can get the actual numbers off the rims, if you need them. I'm sure there are people running even wider tires/wheels, with no issue. Pat
