Kumho V70a vs Bridgestone Potenza RE 71RS — im Vergleich

“Need heat cycle advice I recently got a screaming deal on some Bridgestone Potenza RE-71RS for my daily driver. It usually doesn't see track time but I figured it would be fun to try it out for the cost. The tires were cheap because they had a 2021 production date. In the past to heat cycle a tire, I've just driven on the highway a couple of hours and let the tire sit for 24 hours. The hurdle is, It's winter and too cold to really make an impact. To add to that, I doubt I will have clean enough roads for that tire. My track does have winter lapping when it is clean and dry, but it still may be cold. Any suggestions on how to get a heat cycle on these tires in cold temperatures? Read more”

“Mileage-expectancy of Bridgestone Potenza RE-71Rs? (200-rated, I think?) Forgive me I'm getting the terminology wrong, but I just bought a super dynamite NA Miata that has had a TON of incredible suspension work (mostly Flyin' Miata stuff) and the stickiest tires I have ever experienced by FAR: Potenza RE-71Rs. (Forget full measurements but they're on 15 x 7.5" inch wheels, 6UL's by 949 Racing.) And I think their life is pretty much over. I love them but I don't want to track the car; I want to drive it two hours into the country every other weekend. I want to drive through the mountains with great . . . spiritedness . . . but I don't need track-focused tires. I'd much rather have something slightly less grippy in exchange for longer tread life. The previous owner (who I've stayed in touch with) recommenced I get "300-rated" tires instead of "200-rated" tires. I don't really know what that means or how many miles I can expect from such a tire. I'm contemplating getting the Continental Extreme Contacts, but I just don't know enough about tires to know what they're like or how much ACTUAL mileage I can get----I also dont' understand 200 vs. 300 tires. Please help?”
