Steer tire wear

Uneven tire wear is usually caused by improper alignment, overinflation, underinflation or a worn out suspension.

§393.75 Tires.
(b) Any tire on the front wheels of a bus, truck, or truck tractor shall have a tread groove pattern depth of at least 4⁄32 of an inch when measured at any point on a major tread groove. The measurements shall not be made where tie bars, humps, or fillets are located.

You are in Violation of Safety Regulations regarding Steer Tire Tread Thickness.
Do not drive....Replace ASAP

 

You Dont need to if it still meets the tread depth greater than 4⁄32 inches, But personally....I would just to keep my truck in top shape. Two new Steers is always better than one.

 

I just had that happen to my steer a few weeks ago.

Other tire was half worn and ok but I replaced both to keep them equal to prevent steering pulling or causing uneven wear to the new tire due to different tire height.

 

We are dealing with the same issues of flat spots showing up on the outside rib of steer tires on ALL our LT's after 6-12 months of driving (we have 6 LT's). We thought we had finally figured it out but the issue is popping up again.

What the hell is going on with these trucks?

 

Is it worn like that all the way around or just in one spot? Does the wear correspond to the position of the weights? Are the weights in the center of the rim like they are supposed to be, or close to the inside edge?

 

I just had an almost identical problem with a truck I bought last April. It was wearing deeply in one spot on the outside edge. When we pulled the wheel off we found the weights were near the edge of the rim right where the wear was occurring. Weights on aluminum rims have to be attached along the center line of the rim, not near the inside or outside edge.

I bought a new tire and a set of Centramatics. No problems so far. The new tire has been on for a month.
