Tires OEM Mazda or VITOUR

Go for the Vitour P1. Just out a set on my MR2 this weekend. Wow so much grip

I'm running them on my C7Z (315/345s on 18s). Only one event on them so far (next one is tomorrow) and can confirm they are stupid fast. I was running Conti ECFs previously and about 70% of my first event on the P1s was trying to find the limit and learn the tire.

Tires make more difference than anything. I too bought at used Mazda 3, and thought: "Oooh, this is dodgy in the rain . . ."

Then I got better tires (summers and winters) and realized: "Ohhh, I just had terrible tires."
