Okay I have a stock 87 brat, with no lift. I am looking at the 6 lug conversion abit and was wondering, what size tires would fit on a stock ride brat?

I was kind of looking at the 205x50x15s. That gives me a .5% speedo change and the diamater of the tire is about .1" smaller then stock.

But if I can/should go larger with the stock ride height, please let me know whats the biggest useable, this will be for a street brat, little offroad.

Brain and fingers mismatch- 205x50x13 to 205x50x15

Using the miata tire calculator, I get a ~ 9% difference using 205/50-13 tires.
