Bad tire wear on 2008 2wdrive suburban, tires are becoming choppy soon after purchase.

Sounds like it is either a tire that is low on pressure or you have a valve stem module that is bad. You can have the air pressure checked in all of the tires including the spare. If that does not fix the problem go by a place that fixes and sells tires. They should have a device that can tell which module is sending the low pressure signal. This should be done soon!!!! Because if it is a tire low on air pressure it causes it to run warm, wear faster, and could blow out easier!!! Tires should be checked every month for wear patterns, air pressure and any signs that it could fail!!! Remember your tires are what supports your life look after them!!!!!!

Usually a bad tire or wheel alignment due to worn ball joints , sway bar, or other steering components. Try rotating the tires and see if the roughness moves position. Also check for unusual wear on the tire and proper inflation.

Cars and trucks are supposed to have their tires rotated every 5,000 miles.
Doing this will only slow the wear on the outside of the tire. Whenever you turn a corner, the weight of the car and the forces of friction will cause the outside of the tries to wear off, the rubber is getting "scrubbed off".
Not rotating the tires will cause the outside of the front tires to wear out before any other part of any tire.
Then, there is the matter of worn "front end" parts.
The parts that wear most often and quickest are the tire rod ends. Next are the ball joints, and last are the shocks/struts.
When a car has about 100,000 miles, these parts begin to show their wear by causing bad tire wear.
Someone needs to check your car most carefully to see if any of these parts are causing your problem.
After all the worn parts are replaced, the last thing is the "front end alignment".
As you drive mile after mile, you occasionally hit bumps.
Although these bumps do not show up quickly, the bumps will, over time, cause the tires to become a little crooked, and about once every 3-6 years, the front end needs to be aligned, or have the tires straightened.
Be blessed.

have you looked at the tires- if they are wore down the wear bars-little bands of rubber that cross the grooves in tread will be exposed and the noise is your warning to get new tires soon

check the tires sometime if the tires are choppy they will make a lot of noise.if they are try swapping a rear tire to the front and see if the sound moves location.

{: ) Check for excessive wear on any of the tires on the vehicle and then verify that all the tires are the same size, brand, and same model. It is also important to check and make sure the tire pressure is properly adjusted per the sticker on the door. The following examples listed below could cause this condition:
1. 2 tires on the vehicle are Goodyear P245/75R16 and the other 2 tires are Firestone P245/75R16
2. 2 Tires on the vehicle are brand new and the other two tires have excessive wear.
3. 2 Tires on the vehicle are Goodyear Wrangler SRA 265/70R17 and 2 tires are Goodyear Wrangler HP 265/70R17 (Same brand/different models)
4. Aftermarket Wheels and Tires (NON-OEM 20 inch wheels and tires)
5. Tire pressure is not properly adjusted.

check your tires for cupping by looking for chopped or small flat spots ,steel belt wire sticking out, and rubbing your open hand along the tread.these vehicle are bad about wearing out the tie rod and pitman arms.also if your shocks are over 2 years they may be weak and need replaced.wish you the best.

Chevrolet has a common problem with integral hub and wheel bearings wearing due to exessive use or lack of lubrication, the balls or rollers and races become pitted ,scored or just plain damaged which will infact cause a loud humming or growling noise. I have had some humm at about the same speed but usually they will start to make noise at any speed. I would have to hear the noise to be sure cause there are many things to cause a humming noise like odd tire wear, bad idler pully bearings, e.t.c. the tires should be lifted checked for excessive play in the bearing. Take tire off depress brake piston in just enough secure brake rotor use stethoscope spin hub while listening. maybe he replaced wrong side seen that alot, seen tire noise mistaken for bad bearing to if struts or shocks are worn can cause tires to be choppy. I would recommend taken back 300 dollars is alot of money to not fix your problem.

It could be an out of balance tire
or it could be a bent wheel.
Rub your hand over the surface of the tire. If it's been out of balance, it will feel out of round and choppy.
When the tire is changed the installer can check the wheel to make sure it's not bent.
If it's been bouncing for a while it can wear out the shock prematurely as well
Start with the tire balance...it may need a new tire to solve the noise and vibrations.

If it's choppy the tire is bouncing up and down. Either the tire is not balanced correctly or something is wrong with the shock or spring.
