Although mounting tyres on rims is fairly simple, if done improperly, it can make the vehicle unsafe to drive. When putting a tyre on a rim yourself, know how much air to put in the tyre and make sure it is balanced. If you have any concerns about doing it yourself, take the tyre and rim to an auto mechanic.
Oil the bead of the tyre. Any type of oil will do, but do not saturate the bead with oil. On a flat surface, fit the tyre onto the rim. Do this by positioning the tyre over the rim and push down on the tyre.
Use a tyre iron and rotate it around the wheel to ensure that the tyre is fitted evenly on the rim. To do this, push the tyre iron over the edge of the wheel and about 12mm (1/2 inch) into the tire. The tyre iron will be slightly in the wheel, and you will need to gently pry it out by pulling and manoeuvring it side to side toward you. This forces the bead of the tyre over the edge of the wheel. When you have done this completely around the wheel, you have attached the tyre to the rim. You will have to hold your hand on the tyre, while working with the iron, and push the tyre into place.
Take the tyre to a tyre shop and ask them to place it in a spin balance. This will ensure that it is balanced.
Inflate the tyre to the regulation air pressure standards. Use a pressure gauge to measure the pressure weight.
Refer to your owner's manual for the proper air pressure for the tyre.
