Wheel and Tire question

Hello everyone, I just had a quick question concerning wheels and tires. I just recently picked up a set of pro comp series 40 Vertigo wheels wrapped in a 33x12.50x18 nitto ridge grappler. 2 of the 4 tires have ridges on the tread, uneven wear, or even cupping. the previous truck that these were on was lifted not sure of height or how long lift was installed for, but I believe it possibly had some worn out suspension components and they are most likely due for a rebalance. My question is which of the two would cause a good shake in my steering wheel getting to about 40mph and higher? Everything is fine until then (except the noise for the uneven tread). I’m really hoping it’s just a balance issue and that the unevenness will wear out slowly but surely. Currently switch back over to my original wheels and tires and am just waiting to get this sorted out. Figured I’d ask the community to see if y’all had any input. Any help appreciated, thank you

 

Cupping is common and can cause a shimmy in the steering wheel at highway speed

A wheel balance issue would cause a vibration that can be felt everywhere. The floor, dash, seat, etc

 

Even if everything is perfect it is normal for front tires to wear out sooner on the edges. You'll get some cupping. When you turn corners all the weight of the front of the truck is on the outside edge of the tire on the outside of the curve and the inside of the other front tire. When you go to bigger tires, and tires with more aggressive treads the problem is worse. And worn shocks will make it worse.

If you rotate the tires often and put the cupped tires on the rear they will eventually wear down evenly. IF YOU ROTATE OFTEN. If you leave it too long the cupping will get bad enough that it is there for the rest of the life of the tire.

I'd put the cupped tires on the rear. They will still make noise, but it isn't as noticeable in the cab. They MAY eventually wear down enough to make the areas that are cupped even. If not perfect, they should wear so the noise isn't as bad. But if you wait too long the other tires on the front will start to cup.

I'd say there is a good chance you're going to have to just live with it until you buy new tires. But rotating often will help prevent this. Especially with aggressive off road tires. Guys with cars and street tires can get by with rarely if ever rotating.
