And it's a relatively easy process, however it isn't one that should be taken lightly. You'll be getting some serious life out of your new tires and wheels package, which means those short few minutes of installation mean everything in the long run.
At Tire Rack, we're always happy to recommend an installer but one of the benefits of purchasing rims and tires at the same time is that they come shipped as one unit. Tires are mounted on wheels, which eliminates half the battle.
Start by placing each rim & tires next to their final resting spot on your vehicle. This eliminates confusion at the beginning, and helps keep you organized throughout the process. (NOTE: If you're only replacing two of your tires, those two tires should always be installed on the rear axle.) If you're installing directional tires, make sure the arrow is pointing in the right direction. And if you're installing asymmetric tires, make sure all branding on the sidewall faces outward. Finally, if you're installing tires that are both, look for the "side facing outwards" note on the sidewall and place according to the directional arrows.
And so, you're ready to begin installation.
Step 1: Test fit each wheel.
Step 2: Use a four-way wrench or socket to remove existing lug nuts. Never power tools.
Step 3: Check the fit of each wheel on the hub itself.
Step 4: Remove the wheel from the hub and check the fit of each lug nut or bolt.
Step 5: Temporarily install the wheel to verify brake clearance.
Step 6: With your vehicle in neutral, check for unnecessary contact points.
Step 7: Set wheel lug torque according to your vehicle's specifications.
Of course, those are just the primary points. You'll want to read "How to Install Your Wheel & Tire Package" for detailed instructions pertaining to each step.
