Overall I'm happy with these tires (especially at such a low price) but if the car is parked for a few days or even sometimes just overnight they will develop flat spots until they get a chance to warm up. While this was very common back in the days of bias ply tires it's pretty uncommon for a modern radial. Not sure I'd buy them again.

Great service ..!! great tires ..!! delivered fast ..!! put 2000miles after installed and no problems .. BMW 528I .. handling was awesome..!! thanks guys .. :)

Tires came earlier than expected, so not showing any significant signs of wear. Happy with my purchase.

Great Tire for the money.

Great tires!

Great tire for the rear of an GL1800 Gold Wing F6B.

It has been a very good tire for me and i have recommend someone to y'all. Thank y'all for a great product

The Kumho PA31 replaced some Toyo Extensa HP tires on a Corolla FX16 GT-S set-up for autocross. These are strickly street tires as I run 200 treadwear tires when racing. The Kumho's are WAY better than the Toyo's. The Kumho's stick much better, the Toyo's were always a little greasy at turn-in. The Kumho's seem stiffer with the same air pressure. They inspire more confidence is turns. Ride quality for both is similar. The Kumho's are also better in the wet too! The Toyo's were made in Malaysia. The Kumho's in Vietnam. Both sets were purchased from SimpleTire along with tires for other cars. Always have top notch service from SimpleTire.

Bought these Kumho's to replace Toyo Extensa HP's. They are on an '87 Corolla FX16. The Kumho's were sticky right away. They was no greasy feel like the Toyo's (which never went away). The sidewall tread has a curve which is more conducive to handling, which I like. I was surprised how well these tires handled. I'm quite pleased! I typically run 200 treadwear tires on this car. However, it is parked outside and I need something that is resistant to freezing temperatures. The car is not a daily driver, but is prepped for autocross so it doesn't get a lot of street miles.
