This also applies to the spare tire (if available), even if it is never used. Multiple factors including time, temperature, loading conditions and improper inflation, affect how fast a tire ages. WARNING SIGNS THAT YOUR VEHICLE WILL NEED TIRE REPLACEMENT:. You can see three or more tread wear indicators around the tire. The tire cord or fabric is showing through the rubber.
The tire tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric. Bulge or cracks on tire sidewall.
Uneven tire wear. Flat spots on tire. Center of tire is worn.
The tire has a puncture, cut, or other damage that can’t be repaired correctly. Tires age when stored normally mounted on a parked vehicle.
Park a vehicle that will be stored for at least a month in a cool, dry, clean area away from direct sunlight to slow aging. The area should be free of grease, gasoline, or other substances that can deteriorate rubber. This also applies to unmounted tires. Parking for an extended period can also cause flat spots that may result in vibrations while driving. When storing a vehicle for more than a month, remove the tires or raise the vehicle to reduce the weight from the tires.
Tire rotation is the practice of moving your vehicle’s wheels and tires from one position to another to help promote even tire wear. Even tire wear will help with the life of your vehicle’s tires. It is important to rotate your tires at the intervals recommended by your.
It is recommended that a trained professional rotate your ties and torque to required specifications to help them keep working properly and as designed. It’s important to rotate your tires according to the correct tire-rotation pattern. Doing so can prolong the life of your GMC tires and can reduce the risk of sudden tire failure. Front tires encounter different tasks than the rear tires.
And a front-wheel-drive vehicle’s tires perform different tasks than those on a rear-wheel-drive vehicle. See the Maintenance Schedule section in your for additional information about your specific vehicle. Proper wheel alignment is key to the life of your tires. If your vehicle is misaligned, it can cause your tires to wear unevenly, and you may experience handling problems such as pulling or abnormal vibration.
Tires and wheels are aligned and balanced at the factory to help provide best overall performance. Adjustments to wheel alignment and tire balancing are not necessary on a regular basis.
Consider a wheel alignment check if there is unusual tire wear or if your GMC vehicle is significantly pulling to one side or the other. A tire that is out of balance often affects ride quality and can shorten the life of tires, bearings, shocks, and other suspension components.
If the vehicle is vibrating when driving on a smooth road, the tires and wheels may need to be rebalanced. Camber is the tilting of the wheels from the vertical when viewed from the front of the vehicle. When the wheels tilt outward at the top, the camber is positive. When the wheels tilt inward at the top, the camber is negative.
The amount of tilt is measured in degrees from the vertical. Camber settings influence the directional control and the tire wear. HOW DOES CAMBER AFFECT WHEEL ALIGNMENT?. Too much positive camber will result in premature tire wear on the outside of the tire and cause excessive wear on the suspension parts. Too much negative camber will result in premature tire wear on the inside of the tire and cause excessive wear on the suspension parts.
Unequal side-to-side camber of 1 degree or more will cause the vehicle to pull or lead to the side with the most positive camber. Caster is the tilting of the uppermost point of the steering axis either forward or backward, when viewed from the side of the vehicle. A backward tilt is positive and a forward tilt is negative. Caster influences directional control of the steering but does not affect tire wear. Caster is affected by the vehicle height, therefore it is important to keep the body at its designed height. Overloading the vehicle or a weak or sagging rear spring will affect caster.
When the rear of the vehicle is lower than its designated trim height, the front suspension moves to a more positive caster. If the rear of the vehicle is higher than its designated trim height, the front suspension moves to a less positive caster. HOW DOES CASTER AFFECT WHEEL ALIGNMENT?. With too little positive caster, steering may be touchy at high speeds and wheel returnability may be diminished when coming out of a turn. If one wheel has more positive caster than the other, that wheel will pull toward the center of the vehicle. This condition will cause the vehicle to pull or lead to the side with the least amount of positive caster. Always visit a Certified Service expert technician if you experience any of these situations.
Check your for more information about wheel alignment and tire balance on your specific vehicle. Check your GMC tires at least once a month when the tires are cold, meaning the vehicle has not been driven for at least 3 hours or no more than 1 mile. The Tire Information Label located on the inside of your vehicle’s door frame has the recommended cold tire pressure for your GMC vehicle. Use a quality gauge.
Don’t try to eyeball it - radial tires may appear fine even when they’re underinflated. Look for objects that can get wedged in the tread—they’ll work themselves even further into the tire and cause air loss. To make sure you’re covered, every check of your tires should include a check of your spare (if available), as well. HOW DO YOU KNOW THAT AIR PRESSURE IS LOW OR WHETHER YOUR GMC TPMS HAS MALFUNCTIONED? If the Tire Pressure Monitor light illuminates and stays solid with a Check Tire Pressure, Low Tire Pressure, or Add Air To Tire message, then check and adjust all tire air pressures to the recommended levels.
Next, drive the vehicle to turn the light off. If the Tire Pressure Monitor light appears as a blinking yellow lamp for more than one minute and stays solid, then diagnostic service is needed. If your TPMS is not functioning properly, it cannot detect or signal a low-tire condition. Tire Type The letter 'P' at the beginning of the 'Tire Size' tells us the tire is a P-Metric tire, referring to tires intended for Passenger vehicles. The letters 'LT,' would indicate it was designed for light trucks.
Tire Width Tire width is measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P185/60 R14 tire, the width is 185 millimeters. Aspect Ratio The ratio of the height to width.
For example, in a P185/60 R14 tire, the 60 means the height is equal to 60% of the tire's width. The bigger the aspect ratio, the taller the tire's sidewall.
Construction The letter 'R' in a tire size stands for Radial, which means the layers run radially across the tire. Wheel Diameter The size of the wheel the tire is intended to fit. A size P185/60 R14 tire is made for a 14' diameter wheel. TIRE PLY MATERIAL The type of cord and number of plies in the sidewall and under the tread. UNIFORM TIRE QUALITY GRADING (UTQG) A tire information system that provides consumers with ratings for a tire’s traction (from AA to C) and for temperature (from A to C). Tread wear is normally rated from 60 to 620.
Ratings are determined by tire manufacturers using government-prescribed test procedures and are molded into the sidewall of the tire. MAXIMUM COLD INFLATION LOAD LIMIT This information tells the maximum load that can be carried and the maximum pressure needed to support that load. Find more information on tire pressure and inflation 6. TIRE PERFORMANCE CRITERIA SPECIFICATION (TPC SPEC) Most OE tires designed to GM’s specific tire performance criteria have a TPC spec code molded onto the sidewall. GM’s TPC specs meet or exceed all federal safety guidelines. See participating U.S.
