Vibration on 35s

[borkap]

I am new to having an offroad rig. I bought a jeep with 35's on it and when you drive it at highway speeds there is a vibration to it like the tires may be out of balance. Is this just the way it is or do I need to get them balanced? Its not terrible more annoying than anything and I want to make sure I'm not gonna damage or prematurely wear out anything.

What kind of tires, what kind of jeep etc

Also check universal joints or pinion bearing also had a wrangler thought was tire out on rear but was pinion bearing would only vibrate around 35 and above.

Its an 05 wrangler unlimited Rubicon. The tires are Goodyear wranglers I think and they are 35s.

How do I check to see if mine is out of whack?

 

[rockcreek84]

Do they have any cupping

 

[borkap]

No they look to be wearing normally.

it could be tires or something in driveline. double check drive shaft universals, yoke on rearend, and check balance on tires. if that is not it could also have driveshaft out of balance.

OK I thought I was pretty mechanicaly inclined but I have no idea what to look for when checking them.

 

[rockcreek84]

Check driveshaft for any movement at universals excessive movement means wore out. Check pinion same way should be no movement at all.

Its an Nth degree (AEV) 4.5 inch lift. Ill crawl under it and wiggle things around and see how it goes. Ill report my findings tomorrow.
