How to Mount & Balance Tires
Balanced tires provide a smooth ride and help protect your tire from uneven tread wear. As new vehicles become lighter it's becoming increasingly important to keep your tires balanced. Heavier cars helped smooth out the ride and mask vibrations. You should let an expert mount and balance your tires, but you can do the job yourself if you have the expertise.
Things You'll Need
-Tire stem removal tool
-Bead breaker or rubber mallet
-Dishwashing soap or Murphy's Oil
1 Let the air out of the tire using a tire stem removal tool.
2 Break the bead on the old tire with a bead breaker. If you don't have a bead breaker you can use a rubber mallet. Do not hit the rim with the mallet.
3 Once the beads are loose, lubricate the old tire with dishwashing soap or Murphy's Oil. Use a large flathead screwdriver to pry the beads up over the rim. Let the opposite side of the tire slip under the lip on the rim as you pry the other side over the rim.
4 Lubricate the new tire and put it on the same way you took the old one off. If you're using tubeless tires, replace the valve stem before putting on the new tire (take the old one out, then pull the new one through from the inside). Using tubeless tires will make it a bit harder to inflate. The proper way is to use a valve stem core tool, unscrew the core and inflate the tire. There should be enough volume flowing through the stem to blow the tires out and seal up the beads. Using a tube is easier. Insert the tube inside and inflate it. Then deflate it and inflate it again.
5 Place the wheel on the balancer, making sure the wheel is centered. Spin the wheel and allow it to come to a natual stop.
6 With chalk mark the highest point on the wheel. Cut off a piece of weight and tape it to this part of the wheel. Turn the wheel so the mark is at the 3 o'clock position, then release the tire. If the chalk line points to 6 o'clock weight needs to be remove. If the mark points to 12 o'clock, weight needs to be added. Repeat this step until the tire is balanced.
7 Attach the wheel weights with the adhesive side first.
8 Mount the wheel back onto the car.
