Michelin Super Sport (RCF Spec) - Sidewall softness gripe
#16
So I'm looking to purchase tires, specifically the MPS4S and I wanted to go a little bigger. 265/35 in the front and 285/35 in the rear, and I was a little surprised by the tire shops response. They said if you are going to keep the car, don't change the tire setup it will ruin the car. If you plan to sell it, then you can play with it. How would it ruin the car? Especially that small of a change. I know I will lose a little gas mileage, probably nothing noticeable. But is the car really that tuned to that EXACT tire spec. At the end of the day, for me it's more rubber on the ground for better traction.

ooooooh okay. I remember reading about how the measurements come into play. Maybe that's what he was referring too. Surprised he didn't tell me that, or at least understand why I'm trying to do. What are you running Rolla?

I am running stock setup with stock MPSS tires. Still have about 5/32 left on the rear and 6/32 on the front. I will replace these most likely next spring/summer with MPS4S (2019)

Definitely stock numbers. I think the stock width is quite good. I am also picky about response and length of gear ratios. Larger circumference means, taller gearing and more rubber usually adds more weight per corner. I really like the 20 spoke hand polished design, which is why the real reason I picked TVD/Carbon so I would be sticking with the stock setup, Just not happy with the sidewalls at low engine speeds when the steering is ratio'ed much slower. That results in sidewall flex, which I dislike strongly. I am sure the MPS4S or XL rated MPSS will fix it.

Yea, I totally will do one. I still have some tread left all around, but I'm slipping like crazy. It makes driving hard to enjoy when you give it some gas, let alone romp on it and the traction control kicks. I'm at about 21,500 miles on first set of tires. Which I think is pretty good for the MPSS.
