WHEN YOU SAY WHEEL, DO YOU MEAN THE TIRE?
Yes and no. The "wheel" consists of two parts - tire and rim. When we say "wheel repair" we refer to both rim and tire issues.
SHOULD I REPAIR OR REPLACE A WHEEL?
The price to replace one alloy wheel on a vehicle in 2018 is typically between $600 to $1000. This is because wheels for the majority of vehicles are now primarily made of aircraft grade aluminum instead of steel. Additionally, instead of a plastic hubcap for aesthetics the face of the wheel is a painted, polished, chromed, or machine finished. At Complete Wheel Repair we aim to provide quality work and a cost effective solution for wheel repairs in lieu of purchasing a brand new rim.
WHY AM I CONSTANTLY LOSING AIR IN ONE OF MY WHEELS?
While tire air pressure fluctuates to a degree in relation to outside temperature, you shouldn't be losing air regularly.
If you are constantly losing air or have a slow leak here's some potential causes:
- hole in tire
- insufficient seal between bead of tire and rim
- insufficient seal between valve stem and rim
- bent rim due to large potholes
- cracked rim due to large potholes
What is Road Force® Balance?
Road Force® measurement is a procedure developed by Hunter Engineering Company to determine the amount of radial force variation of a wheel and tire assembly. It works by test driving the wheel using a load roller that applies up to 1,250 lbs of force on the tire as it rotates to simulate the weight of a vehicle. It measures the wheel and tire assembly pushback on the roller as it rotates. The tire is then rotated on the rim to a specified location to match the high spots of the tire to the low spots of the rim. This allows the assembly to rotate with uniform pressure, eliminating potential vibration and irregular tire wear. This precision balancing method is often desirable for high performance vehicles or anyone who prioritizes the best ride quality in their vehicle. We offer this premium service in addition to traditional balancing. Give us a call for more information or to request this service.
Why am I experiencing vibration when I drive?
Vibration issues can be caused by a number of factors and can be difficult to diagnose. Most commonly vibration issues are caused by the wheel and tire assembly. Reasons for vibration can include:
- Tire and wheel are out of balance
- Tire has uneven treadwear due to misalignment or other suspension issues
- Bent rim
- Blister in tire
- Damaged suspension components or misalignment
- Bent hub
Most vibrations are only felt at a specific speed or speed range (ie: 55-60mph). This can be caused by a bent rim that is within specification overall but is over the limit for a specific harmonic. When measuring wheels we verify the first, second, and third, harmonics of the rotation are within specifications as well as the total indicated reading. The first harmonic determines if the barrel of the wheel has an egg shape. The second harmonic determines if the barrel has an oval shape. The third harmonic determines if the barrel has a triangle shape. Using our Hunter GSP9700 we are able to take these measurements during our straightening process to ensure that when we are finished straightening a bent rim it meets factory specifications.
Why are lighter rims and tires better than heavier ones?
A lighter rim and tire combination can increase performance of your vehicle and improve overall ride quality due to a principle called "unsprung mass". The mass of the vehicle body and other components supported by the suspension is the "sprung mass" while "unsprung mass" includes wheel axles, wheel bearings, wheel hubs, tires, and a portion of the weight of driveshafts, springs, shock absorbers and suspension links. When the amount of unsprung mass is reduced, the amount of force put into the shock absorber is lowered. This puts less force into the chassis of the vehicle improving the overall ride quality.
Why does my tire have a blister on the sidewall?
Blisters on the sidewall of a tire are caused by driving on the tire with not enough air pressure. Although not as common, it can also be caused by pinching the tire for extended periods of time against a curb. A blister is a sepearation of the layers of the sidewall, which air can enter, forming a blister that can be seen on the outside of the tire. In this scenario, the tire cannot be repaired and must be replaced immediately to avoid a potential tire blowout and road hazard.
