steering vibration

[lriutta]

I have a 99 Silverado with over 200,000 miles. for about 75,000 miles the truck has vibrated like the tires out of balance. I have had the tires balanced every month and the problem is still there. It starts about 35-40 mph and the faster I go the worst it is. I live in the desert so it cant be snow or anything like that. I do have oversize tires on it and a 4" suspension lift on it also, but it is a 2 X4. My tires are not wearing even but I took the truck to the dealer for an alignment. I have no idea what is can be.

Check your wheel bearings.

Check your wheel bearings.

If there are any left after 75'000mls of shaking...

 

I have been working temporary in a tire shop. So I don't have sooo much experience.

But we had always had problems to balance oversize tires.

Sometimes it wasn't even possible.

 

I would try to borrow a regular set of wheels and tires and try it.

When the vibration is gone you may consider different tires. If not then there is something else wrong.
