Put these on my front (Prarie 400 4x4) last summer before I started trail riding (replaced some worn Bridgestone's) and I have to say I'm very impressed with them so far. They are agressive but not too agressive (like mudders). I also love the colored logo stamp on the sidewall. I would have got them for the back but they don't make them that size (went with Carlisle instead as they were good price and only real choice for the size I could find). Anyone else have the Dirt Devil's? How are they holding up?

 

Put them on the front of a Honda 300 several years back. Really liked them, plus at the time they were very cheap. Like $38 a tire for the fronts cheap. That quad barely ever gets ridden, but the tire was getting good reviews on here when I decided on them over Bear Claws.

 

Any aftermarket tire is a improvement over the 2 ply crap from stock. Only Polaris seems to put decent 6ply tires on from the factory.
I have seen new grizzlys and foremans on the show room floor and the tires looked bald.
