Wheels I got have 2 good tires for the rear still, Potenzas, looking to change the 2 to run in the front, what would be good size and not have to worry about any rubbing issues. 235/40/18 or what do you guys think? The potenzas will go on the back , 245/40/18, dont want to buy 4 new right now so just lookin for up front.

I'd go 235/40R18 per Miata calculator, to keep your speedo close to speed

Put stock size, I'm guessing 205/65/r15 and then put aftermarket, 235/40r18. 15's spin 791 rpm and the 18's spin 794 rpm so you will be close to exact speed. Be careful using 2 different sizes as your ABS "may" sense that 2 wheels are moving faster or slower and could set off abs or low tire light. That would be "if" you have abs

lemme know which tire you get, I work at a Firestone and we sell bridestone, firestone, and fuzion performance tires and I could ship if you wanted
