I replace my Corvette and Z06 tires with non run flats, I use the same size Michelin 4s, to me a softer ride with better handling

 

I will definitely go non-RF like I did with my previous ATS. It will be between the Michelin Pilot Sport All Season and Continental Extreme Contact DWS. I generally go Michelin, but kinda want to try the Conti's to see what they are like. I don't need summer tires for my driving habits.

 

My 2025 CT5V has Michelin Pilot Sport All Seasons, had the dealer put them on as part of the deal. Ride and noise are great..

 

After just two months and a little over 1100 miles of ownership, my only big complaint (not enough to dampen my delight with the car) is the road noise from the tires. Hopefully it will lessen with more miles. I don’t know the biggest factor causing the noise: run flats, 20” wheels, or Michelin pilot sport A/S – likely, a combination of all, but I will be replacing the run flats later. I don't have complaints about the ride comfort. It pains me to spend over $1000 to replace perfectly usable new tires. We’re going to take a 2,000 mile road trip later this month, so I’ll see how that goes.

Here’s what Tire Rack’s tool recommended based on my criteria (I'll do more research when closer to making the change):

Great information - Thanks!

 

I went with Continental Extreme Contact DWS, the difference is great. Better ride, handling, less noise.

 

Ended up replacing RF's with the Continental Extreme Contact DWS - love the difference. 100% agree with T's C6.
