I bought a set of ITP Holeshot XCT 23x7x10 (Front) tires and have had nothing but trouble with them. I took them to my local shop for mounting. The ATV now vibrates like crazy. It's tough to keep it under control because the from wheels are out of balance.
Once I hit about 15 miles per hour, I can see the front right tire bouncing up and down! The left tire is not quite so bad.

What is the possibility that these name brand tires are out of spec? I put my old tires back on the things work great.

I hope Rockymountain ATV will take them back...

 

Try turning it 180 degrees on the rim, and see what happens. The tire and the rim may each be imbalanced, and together they are adding to each other. Turned, they might cancell each other out.

I have found ITP to be very helpful. I had a defective tire once, called them, and they shipped me a new one and it was here the next day! Give ITP a call if Rocky Mountain can't help you.......
