I was not told or read anything about this tire for my Corvette Grand Sport being a run flat tire. I found out from the dealer a few days after having the tires installed when I returned to have to lug nuts checked for exact tightness. The tire is very noisy and a hard ride.

Excellent tire. The compound is sticky and aggressive while still offering good traction in cold weather. The tires appear to be well made with a very still XL-rated sidewall. Handling is extremely precise and predictable with perfectly controlled behavior when approaching the limits of cornering grip. The tires are very comfortable and pretty quiet for a performance A/S tire. While I cannot comment on tread life or highway stability just yet, no doubt those will meet expectations as well.

Bought these tires for my "New to Me" 2012 Lexus LS460. Ride improved greatly. These tires are also very quiet. While my car isn't a sports car, it does have a top speed of 150+, so I needed a "Z" speed rating. While it doesn't like to be pushed, the grip does feel more stable. Over all highly impressed with these tires.

The safest tire in the market. I wish you sell 15's and17's for my Smart Fortwo car. All 4 of my other cars use Michelins.

These tires are outstanding. From road feel to traction and handling they have exceeded my expectations. For street tires I don't think you can do better. The 40F limit of temp is something to consider if you are driving in the mountains.

quiet, smooth ride in my roadster. The handling is excellent although I don't tend to push the limits of driving.

First set, replaced pilot sport 4 summer tires. Better mileage warranty, wet grip & ride in my opinion.

These are great tires: quiet, great traction and responsiveness, very good tread life and durability. Allows me to drive with confidence in rain or snow.

245/45R pilot 4 on 2008 sky immediately noticed quieter and smother ride then Good year. Car easy to break rear traction mostly due to light rear end, will see what happens w/pilotswhen rods dry up and clean up.

For an all season tire, it is good on a dry, cool, onramp for lateral g-force, but traction loss is inevitable during medium parking lot to road acceleration in warm weather (30°C).
