Installing a tire yourself means removing the old one, mounting the new one onto the wheel, and reattaching it to your car
You can install a tire in your driveway with basic tools: a jack, a lug wrench, and a tire iron (or a multi-tool that includes one). The job takes 30 minutes to an hour if you have done it before, longer if this is your first time. The hardest part is usually breaking the bead — the seal between the tire and the wheel — which requires either a tire machine or a tire lever and some force.
Most people have a tire shop do this work because the shop has a tire machine that mounts and balances the tire in minutes, and because the shop can dispose of your old tire. But if you own the tools and want to do it yourself, the steps are straightforward and the main risk is damaging the wheel rim if you slip with the tire iron.
Key Takeaways
- You need a jack to lift the car, a lug wrench to remove the wheel bolts, and a tire iron or lever to break the bead and pry the tire off the rim.
- Breaking the bead — the seal between tire and wheel — is the hardest step and usually requires a tire machine or a tire lever and leverage.
- After mounting the new tire, you must have it balanced at a shop, because an unbalanced tire will vibrate and wear unevenly.
- Tightening the lug nuts in a star or cross pattern prevents the wheel from sitting crooked and ensures even pressure.
What you need before you start
Gather your tools on a flat, level surface away from traffic. You will need a car jack (the one that came with your car works, though a floor jack is easier to use), a lug wrench (the cross-shaped wrench that fits your car's lug nuts), and a tire iron or tire lever (a flat pry bar designed to separate the tire from the rim). You will also need the new tire itself, and ideally a tire machine to mount and balance it — most people rent one from an auto parts store or have a shop do this step.
If you are breaking the bead by hand, you will also need a tire lever (a flat metal bar, different from a tire iron) or a screwdriver, and something to protect the rim from scratches — a cloth or old towel works. Do not use a hammer or hit the tire with force; you will damage the rim.
Removing the old tire
Loosen the lug nuts by a quarter turn while the car is still on the ground. This breaks the initial resistance; if you wait until the wheel is in the air, the wheel will spin and you will not be able to turn the nuts. Use the lug wrench and turn counterclockwise.
Lift the car with the jack until the tire is about six inches off the ground. Place a jack stand under the car frame as a safety backup — never work under a car supported only by a jack. Remove the lug nuts completely and set them in a safe place where you will not lose them. Pull the wheel straight toward you to remove it.
Breaking the bead and removing the tire from the wheel
The bead is the rubber edge of the tire that sits against the wheel rim. It is sealed tight, and you must break this seal before you can pry the tire off. If you have access to a tire machine, this step takes seconds. If you are doing it by hand, you have two options: use a tire lever and leverage, or drive the car slowly over the edge of the tire to break the bead (risky and not recommended).
With a tire lever, place the flat end under the bead at the edge of the rim, protect the rim with a cloth, and pry upward. Work your way around the tire, breaking the bead all the way around. Once the bead is broken on both sides, use the tire iron to pry the tire off the rim. Start at one point and work your way around, lifting the tire edge over the rim lip. This takes patience and arm strength; do not rush or you will bend the rim.
Mounting the new tire onto the wheel
This is where a tire machine saves time and prevents mistakes. The machine stretches the tire onto the rim and seats the bead in seconds. If you are doing this by hand, you will need to position the tire over the rim, then use the tire iron to work the tire edge over the rim lip all the way around. This is difficult and risks damaging both the tire and the rim.
Once the tire is mounted, you must have it balanced — a machine spins the wheel and adds small weights to the rim to correct any heavy spots. An unbalanced tire will vibrate at highway speeds and wear unevenly. Most tire shops balance a tire for $15 to $30, and many include balancing when you buy a tire from them.
Reattaching the wheel to the car
Lift the car again and slide the wheel onto the lug bolts. Hand-tighten the lug nuts as much as you can, then lower the car to the ground. Once the car is resting on the tire, tighten the lug nuts in a star or cross pattern — if the nuts are at 12, 3, 6, and 9 o'clock, tighten 12, then 6, then 3, then 9. This ensures the wheel sits evenly and the pressure is balanced.
Tighten the nuts firmly with the lug wrench, but do not over-tighten; you should not need to strain. If you have a torque wrench, your car's manual will list the correct tightness in foot-pounds. After driving a few miles, stop and re-check the lug nuts — they sometimes loosen slightly as the tire settles.
When to have a shop do this instead
If you do not own a tire machine or tire lever, or if you are not comfortable working under a lifted car, a tire shop will install a tire for $15 to $45 depending on the shop and your location. The shop will also balance the tire, dispose of your old one, and check your other tires for wear. This is often worth the cost, especially if you are buying the tire from the shop anyway.
If you damage the wheel rim while removing the tire, a shop can assess whether it is safe to use or needs replacement. A bent rim can cause the tire to lose air or vibrate dangerously.
Frequently Asked Questions
Can I install a tire without a jack?
No — you need to lift the car to remove the wheel. A car jack is essential. Never work under a car supported only by a jack; always use a jack stand as backup.
What if I do not have a tire machine?
You can mount a tire by hand with a tire iron and patience, but it is difficult and risks damaging the rim. Most auto parts stores rent tire machines for $20 to $40 per day. Alternatively, have a shop mount and balance the tire for you.
Do I have to balance the tire after installing it?
Yes. An unbalanced tire vibrates at highway speeds, wears unevenly, and can damage your suspension. Balancing costs $15 to $30 and takes 15 minutes at a shop.
What if the lug nuts are stuck?
Spray them with penetrating oil (like WD-40) and wait 10 minutes. Use the lug wrench and explore steady pressure rather than sudden force. If they still will not budge, have a shop remove them — forcing a stuck nut can strip it or break the bolt.
How tight should the lug nuts be?
Tight enough that you cannot turn them by hand, but not so tight that you strain with the wrench. Your car's manual lists the exact tightness in foot-pounds if you have a torque wrench. After driving a few miles, re-check them because they sometimes loosen as the tire settles.
