Seeing new tires on your truck is more than a visual upgrade—it changes stance, ride height, and how the truck fills its wheel wells. This guide walks you through the practical steps of mounting, fitting, and evaluating new tires, from measuring clearance to checking pressure, so you know exactly what to look for and how to do it safely.
Ingredients
- 1 set of new tires (correct size for your truck, e.g., 265/70R17)
- 1 floor jack (3-ton capacity or higher)
- 2 jack stands (rated for your truck’s weight)
- 1 lug wrench or impact wrench
- 1 torque wrench (ft-lb)
- 1 tire pressure gauge
- 1 tape measure or ruler
- 1 spray bottle with soapy water (for leak check)
- 1 wheel chock (for opposite wheels)
- Optional: 1 set of lug nuts (if old ones are worn)
Instructions
- Park your truck on a flat, level surface and engage the parking brake. Place a wheel chock behind the rear wheels (if lifting the front) or in front of the front wheels (if lifting the rear).
- Loosen the lug nuts on the wheel you’re replacing by turning them counterclockwise about half a turn, while the wheel is still on the ground. Do not remove them completely yet.
- Position the floor jack under the truck’s designated jacking point (refer to your owner’s manual—usually on the frame near the wheel). Jack the truck up until the tire is about 2 inches (5 cm) off the ground.
- Place a jack stand under the frame or axle near the jack point, and lower the truck onto the stand. Ensure it’s secure before proceeding. Never work under a truck supported only by a jack.
- Remove the loosened lug nuts completely, then pull the old tire straight off the hub. If it’s stuck, gently tap the tire sidewall with a rubber mallet—do not use a metal hammer on the wheel.
- Clean the hub surface with a wire brush to remove rust or debris. This ensures a flat mounting surface.
- Mount the new tire onto the hub, aligning the wheel holes with the studs. Push it on until it sits flush against the hub.
- Hand-thread the lug nuts onto the studs, turning them clockwise. Tighten them in a star pattern (crisscross) until they are snug, but not fully torqued.
- Lower the truck back to the ground so the tire is just touching the pavement (but the truck’s weight is still on the jack). Using a torque wrench, tighten the lug nuts to your truck’s recommended torque (typically 80–100 ft-lb for light trucks; check your owner’s manual). Use the same star pattern.
- Once all lug nuts are torqued, lower the truck completely and remove the jack and stand.
- Check the tire pressure with a gauge. The correct pressure is printed on the driver’s side door jamb sticker (not the tire sidewall). Inflate to that cold pressure, usually 35–40 psi (240–280 kPa) for light trucks.
- Spray the tire bead (where the tire meets the rim) and the valve stem with soapy water. Look for bubbles, which indicate a leak. If none appear, you’re good.
- Repeat steps 2–12 for each wheel you’re replacing.
Tips
- Check clearance: Before driving, turn your steering wheel full left and right to ensure the new tires don’t rub against the fenders, suspension arms, or brake lines. If they do, you may need wheel spacers or a lift kit—do not drive with rubbing tires.
- Torque matters: Over-tightening lug nuts can warp the rotor or break studs; under-tightening can cause the wheel to come off. Always use a torque wrench, and re-torque after 50–100 miles (80–160 km) as the wheel settles.
- Match tire size: If you’re upsizing, keep the overall diameter within 3% of the original to avoid speedometer errors and ABS issues. Check your owner’s manual or a tire size calculator.
- Spare tire: If your spare is older or a different size, note that it may affect handling if used. Ideally, rotate all five tires, including the spare, to ensure even wear.
Serving Suggestions
Once your new tires are on, take the truck for a short test drive (5–10 miles) at varying speeds. Listen for unusual noise, feel for vibrations in the steering wheel, and check for any pulling to one side. After the drive, re-check the lug nut torque and tire pressure—this is your “taste test” to confirm everything is seated correctly.
Variations
- Larger tires (e.g., 33-inch or 35-inch): May require a leveling kit or suspension lift to avoid rubbing. Expect a slight decrease in fuel economy and a rougher ride.
- All-terrain vs. mud-terrain: All-terrain tires are quieter and better for highway; mud-terrain tires are more aggressive for off-road but noisy on pavement.
- Winter tires: If you live in snowy areas, consider a dedicated set of winter tires mounted on separate rims for easy seasonal swaps.
Storage and Reheating
If you’re storing your old tires, clean them and keep them in a cool, dry place away from direct sunlight and ozone sources (like electric motors). Stack them flat or stand them upright—do not hang them for long periods. Tires stored properly can last 6–10 years, but if they show cracks or bulges, replace them. For the new tires, they don’t need “reheating,” but do check pressure monthly, as tires lose about 1 psi per month naturally.
Frequently Asked Questions
How do I know the right tire size for my truck? Look at the sticker on the driver’s side door jamb. It lists the original tire size and recommended pressure. If you want to change size, use a tire size calculator to keep the diameter within 3% of original.
Can I replace only two tires instead of all four? It’s best to replace all four if possible, especially on 4WD or AWD trucks, because different tread depths can damage the drivetrain. If you must replace only two, put the new ones on the rear axle to maintain stability.
How often should I rotate my new tires? Every 5,000–8,000 miles (8,000–13,000 km) or as recommended in your owner’s manual. Rotation ensures even wear and extends tire life.
Why does my truck vibrate after new tires? It could be an unbalanced tire, a bent rim, or improper lug nut torque. Go back to the shop (or re-check your work) and have the tires balanced and the torque verified.
Do new tires need a break-in period? Yes, drive moderately for the first 100–200 miles (160–320 km) to remove the mold release agent on the tread. Avoid hard acceleration, braking, and high speeds during this period.
Can I use a different tire brand than the original? Absolutely, as long as the size and load rating match. Different brands have different tread patterns and compounds, but any quality tire that fits will work.
