You can install a tire on a rim yourself and save money. For safety reasons, however, it is crucial to have the appropriate tire for the rim. Tires and rims are clearly marked for size and the tire should be the same size as the rim, such as a inch tire on a inch rim. If the size of your tire does not match the rim, buy a new tire or rim, or take your tire and rim to an auto garage and consult a professional. Lubricate the beads of the tire with dish detergent and lay the tire on the rim.
The beads of the tire are the inside edges, around the hole. Always follow the vehicle maker or wheel maker torque specifications. Just remember that tighter is not necessarily better. While you should always adhere to the torque specifications listed by either the vehicle make or the wheel maker, the box below offers a broad guideline of torque values for common wheel Lug Nut sizes. Always tighten any wheel in the proper sequence pattern in order to evenly distribute the clamping load between the wheel and the hub.
The goal in using the proper tightening pattern is to avoid concentrated areas of clamping force. You want to evenly distribute the clamping load across the hub surface. Then move to a Lug Nut furthest away from that second Lug Nut, etc. Always move to the Lug Nut that is furthest away from the previous Lug Nut.
The same rule applies. Always move to the Lug Nut that is furthest away from the previously-tightened Lug Nut. Instead, tighten in at least two steps. For instance, if the specified torque value is ft. Then perform a second tightening to full value using ft. By tightening in multiple steps, you greatly reduce the chance of initiating excessive clamping force in isolated areas.
Taking this extra care is but another way of increasing your chances of achieving an optimum wheel-to-hub clamping load. Your email address will not be published. Home :. Gallery :. Click here to jump to that post.

The wheel system is newer than the latest MSCeditor. Set it on the machine and engage the hydraulic press that secures the rim in place from beneath by pressing the pedal associated with it. Most tire machines have two pedals: one to engage the press and another to rotate the rim. If you're unsure which pedal does which or if there is no pedal on your particular machine refer to the tire machine owner's manual or the manufacturer's website for guidance.
Slide the tire over the rim on an angle. Position the bottom edge of the tire lower than the top edge of the rim on one side, with the tire sitting at about a degree angle. The tire should be able to sit on its own without falling off the rim.
Swing the mounting arm down onto the edge of the rim. Position the mounting arm so it makes contact with the rim's outer edge in the same spot you've already angled the tire to get past. If you can't squeeze the mounting arm in at that spot, re-adjust the tire to give yourself room to get the mounting arm in.
Angle the tire so the lower bead is aimed at the mounting arm. With the mounting arm in place, you may need to adjust the tire slightly so that it comes into contact with the arm as the wheel and tire rotate. In most cases, this won't require an adjustment at this point, but look things over to ensure the proper angle.
Make sure the tire is positioned so that the arm presses the lip down past the rim's edge as it rotates. If the tire falls off the rim, it's not angled properly. Press the pedal to rotate the rim and tire.
As the two rotate, the mounting arm will force the bottom bead of the tire over the rim's top edge. Continue to rotate the two until they complete one full circle and the tire's bottom bead is entirely past the top lip of the rim.
The tire's top bead will be all that stops it from setting all the way onto the wheel. Reposition the mounting arm to guide the tire's upper lip onto the rim.
Just like before, press one side of the tire down with your hands until it dips beneath the upper lip of the rim, then lower the mounting arm down onto the rim's edge in the space you've created by hand.
The tire will once again sit at an angle once the mounting arm is lowered into place. Press the pedal to rotate the tire and rim again. As the wheel and tire rotate, the mounting arm will now force the tire's upper bead down over the lip of the rim. Once you complete one full circle, both the tire's upper and lower beads will be passed the rim's upper lip.
Inflate the tire with an air compressor. Connect the air compressor hose to the end of the valve stem you installed earlier, but make sure you get your hands and clothing completely clear of the tire before you turn the compressor on. Once you start the flow of air, the tire will rapidly inflate.
Once inflated to the proper air pressure, the tire is mounted. Method 2. Insert the valve stem if there isn't one present. Lubricate the valve stem with a bit of tire lubricant, then press it into the hole on the inner portion of the rim where the tire will later cover.
Next, take a pair of pliers and pull the valve stem outward from the hole. Lubricate the tire bead and rim.
