Nice tires. Run small!
Ride well. Great traction. Haven’t had a puncture yet. They run small. Same spec size 20x10-9 but quite a bit smaller. Both tires are mounted and at 5psi in pic. The old ones ran a little big but it’s pretty substantial. Would buy again, just larger size to compensate

Reviewed in the United States on April 12, 2019
Tires seem to be of very good quality. Installed these on my son's quad and they have amazing grip. I have $600 worth of ITP mudlites on mine and he was going thru the mud easier than I was. Think of them as ITP holeshots for a faction of the cost.

Reviewed in the United States on January 7, 2019
Couldn’t be any happier with this purchase! Tires were set to come in on either the 7-9th of January and came in on the 5th. Great tires already went Mudding and Thru the Dunes and nothing better then a great Grip while riding. I’ll definitely be buying another set once needed.
