My kids have a Honda TRX 90 and the rear tires need to be replaced. What do you guys suggest for a good trail riding tire for this machine?

 

A freind of mine put on Turf Tamers on some wider aftermarket rims. This make it wider so the kid wouldn't tip it over so easily!

When I had to decide on new tires, I just went with the same ones as stock. They preform well in a variety of condition, and do especially well on technical terrain. My kids use to ride with me everywhere I went on my 4wd, and the tires were a huge help (when they got hung up, we would just pick the little quad up and carry it).
