Yes, you can put spacers on just the back wheels. Wheel spacers are designed for functional and cosmetic. When the front wheels look good but the back wheels stick in a little too far, you can add wheel spacers to the rear to fill out the rear wheel arches. The rear track matches more closely to the front, which improves the appearance significantly. Just properly torque every wheel lug and they should be fine.
By moving the wheels and tires further from the suspension, wheel spacers create more backspacing which is good to prevent larger tires from rubbing against the inner fenders, shock absorbers, brake calipers, or other parts. It’s no different than running a rim with a lower offset. As long as you install the same size spacer to each side of the rear. There’s no problem running them only on the back wheels.
What Sizes of Wheel Spacers Are Safe?
For those people who add spacers on the back wheels only, choosing a proper set of wheel spacers is important. The safe size wheel spacer should keep the wheels and tires staying in the fender arches. This is because both front and rear fenders are important. They prevent the rolling mud or debris from hitting anyone or anything. Keeping the tires still covered by the fenders ensures safe driving.
If the wheel alignment was fine before, it will be fine after installing wheel spacers. They do not affect toe in, camber, or caster. That is to say, you do not need an alignment if you are just adding spacers. Properly spacing the tires out increases the track width. This not only adds more stability but also makes your car look cooler.
Will This Increase Tire Wear on The Back Wheels?
No, using wheel spacers of proper thickness will not cause any rubbing issues. By changing the position of the wheels, wheel spacers affect the backspacing and offset directly. If you intend to run wider tires, you’ll typically need wheel spacers to reduce the offset. This is effective to prevent the sidewalls of new tires from rubbing any suspension parts. The rear wheels properly rotate in the fenders, adding spacers on the back only will not increase tire wear.
When installed, wheel spacers become the important parts that connect the wheels and hub assembly. If you’re going to make sure any part of your car is safe, always stick to quality wheel spacers. Make sure you are investing in trusted brand spacers. Brand manufacturers always try to make their wheel spacers better in strength, toughness, and corrosion resistance. It is worry-free to use genuine brand wheel spacers.
