Chevrolet Silverado Tires, Payload Wear and Truck Service

Wear on both outer edges usually means the tire is running underinflated for the weight it carries. A Silverado with a loaded bed, a toolbox and a ladder rack squashes the tire more, so the shoulders do the work. Heat builds, tread wears unevenly, and the sidewall takes stress.

What we check:

1. The load in the bed on a typical day
2. The tire's load index and load range
3. The pressure you run versus what the load needs
4. Rotation history

LT tires often need higher pressure than the placard's P-metric number when loaded. We set it from the tire's load chart. See tire wear patterns.

Silverado configurations vary a lot. Base work trucks often ride on 17-inch wheels, while higher trims use 20- or 22-inch wheels, and off-road trims come with all-terrain tires on a raised suspension. The placard is the starting point.

Large wheels with low-profile tires ride sharply and bend more easily on potholes. We will point that out before you pick a look over a function.

Leveling kits and lifts change the steering geometry. Many level kits stay within factory adjustment range. Taller lifts may need aftermarket parts to bring camber back to spec. We print before and after numbers and tell you when stock parts are at their limit.

Bigger tires also affect speedometer accuracy and braking effort. If driver-assist cameras are fitted, a height change may affect them, and we note that on your estimate. See wheel alignment.

Heavy trucks work their brakes hard, especially when towing or running a loaded bed in traffic. We measure pads and rotors, check fluid condition, and photograph everything. See brake service.

On 4WD Silverados, the front differential, rear differential and transfer case each need fluid attention. Towing and heavy use shorten the interval. We check for leaks and confirm 4WD engages correctly.

Yes for routine maintenance. Depending on the year, a Silverado 1500 may have a turbo four-cylinder, a V8 or a light-duty diesel. Diesels need the correct oil specification and fuel filter service, and a fuel-water separator check is part of good diesel care.

Our diesel maintenance page covers what we handle on light-duty diesel trucks.

The Silverado 1500 has gone through several engine and transmission changes, and each era has a short list of items that owners and technicians bring up often. Use it to aim the inspection, not to judge a truck you have not seen.

Exhaust manifold bolts are another frequent find on older V8 trucks. A tick that is loudest on a cold start and fades as the engine warms often points there.

Safety campaigns are a separate question from wear. Enter your VIN at NHTSA's recall lookup (opens in a new tab) before you plan a repair.

Base it on hours and loads, not only miles. A contractor truck that idles at job sites and carries a full bed all week ages faster than its odometer suggests. The oil life monitor accounts for some of that, but it cannot see dust, payload or trailer weight.

Before you buy a used work truck, ask for these same records. A truck that followed this kind of rhythm is a safer bet than a low-mileage one with none. If you run several trucks, our fleet maintenance page explains how we plan visits around your crew.
