Out of round tires

When I brought my new rancher home and ran it around from where I unloaded it to the garage in front I felt the tire bump on each revolution. I thought it was probably a flat spot from sitting that would eventually round out. It's been in a heated garage for a couple of months with almost no riding but each time I take it out the thump is still there. Today I jacked it up so the rear tires were off the ground by ¼ inch or so and when I rotate them there is a spot on the tire about 8 to 12 inches long that rubs the floor, the rest of the tire clears by about ¼ of an inch so it appears there is a bulge in the tire instead of a flat spot. This makes for one heck of a rough ride on anything over 10 miles an hour. Have any of you ever experienced this with a new rig and stock tires?

 

This can happen if they are over inflated. Whats your tire pressure? I'd check there first.

Right now they are 3.6 lbs. Not sure when I brought it home, seems like they were a little under that.

Is the inside bead of the tire seated properly? I have seen this on bike tires before.

Also, check that it isn't the rim that is not round. Look at the bead lip while turning the tire.

Lastly, watch the hub and make sure that is not untrue. Or the rim not seated out correctly on the hub.

If the tire, rim or hub is truely out of round take it back to the dealer and explain the issue.

 

Still on warranty??? If so, take it back and demand new tires.

 

Thanks. I checked the outside of the rim and the outside bead but didn't think about looking at the inside. I'll ceck that out tomarrow and yes it's still on warranty. Good advise,I think I'll take it to the dealer Monday.

StanD, Dealer is probably open till at least 2 on saturdays, then you wouldn't have to rush if your in a pinch for time monday.

 

I think there was another post like this a while back. Quite possible that Maxxis has a bad batch that just needs to get replaced.....

 

Happens when the units are strapped down in the crate for shipping

Really noticeable in the rear

Remove one rear tire and bolt it back on 1/4 turn from where it was

The out of roundness will be less noticeable and when the quad is rode this summer in warmer weather the bumps will go away to where the tires will regain their natural molded shape
