A wheel is the entire piece. It is made up of a hub, spokes, and a rim. The rim is the outer-most portion of the wheel.
The wheel hub is the mounting assembly for the wheel. The wheel hub function is to keep the wheel spinning freely and keep it attached to the vehicle.
Wheel offset is the distance between the centerline of the wheel and the mounting surface. The mounting surface can be even with the centerline, protrude forward, or recessed backward from the centerline.
The rim is the outermost part of the wheel. It is made up of the barrel, bead, and flanges.
TPMS stands for tire pressure monitoring system. It is an electronic system in your tire that monitors the pressure in your tires. It activates a warning light on your dashboard to let you know if your tires are over or underinflated.
A staggered fitment means that the wheels on the back of the car are not the same size as the wheels on the front of the car. With staggered wheels, the wheels and tires are wider on the rear axle than the front axle. Staggered fitments are not possible on front wheel drive vehicles.
UCSAUTOPARTS proprietary fitment system guarantees a perfect fit. First the overall wheel and tire diameter are verified to be within 3% of OEM. Then bolt pattern and offset are verified. If you have upgraded the brakes or suspension on your vehicle, let our Customer Service team know before you buy your wheels. If your off road vehicle has been lifted, be sure to note the lift in inches.
As you change the size of the wheel you must change the size of the tire to maintain the overall diameter. You’ll get a slight decrease in fuel economy and acceleration. The trade-off is better handling and greater visual appeal. Off road vehicles will have increased stability on the trail.
Technically, the rim definition refers to just the outer portion of a wheel. You can’t replace the rim without replacing the entire wheel. Replace wheels when they are damaged or when you want to change the look or performance of your vehicle.
Changing car wheels can increase your car’s performance and give your ride a new look. Change your car wheels to a staggered fitment for a more aggressive stance or upsize to increase performance.
