When should you replace your tires? Age, tread, damage, and cost guide
You should replace your tires when they become unsafe—at 3/32" of tread depth, at six years of age (regardless of tread), if they show visible damage, or if they’re no longer performing safely.
Unsafe tread depth: Replace tires at 3/32" of remaining tread. Tread that low reduces wet traction and stopping distance. Learn how to check tread depth.
Tire age: Replace at 6 years of age. For your safety, Discount Tire will not service tires 10 years or older. Learn about tire aging.
Irregular treadwear: Cupping, feathering, inside/outside wear, or flat spots signal alignment, inflation, or rotation issues that may require replacement. See wear patterns. Many stores now offer wheel alignment.
Bulges or bubbles: Sidewall bulges/bubbles can lead to failure and cannot be repaired. Replace immediately.
Cracking or dry rot: UV exposure, temperature swings, and long periods of sitting can dry out rubber. Dry rot cannot be repaired. What dry rot looks like.
Reduced safety or performance: Longer stops, poor wet grip, shaky handling, or excess vibration—even with “okay-looking” tread—are reasons to replace. Get a free tire inspection.
You’re not satisfied: Noise, ride harshness, or early wear? Review the brand’s satisfaction policy and our return policy.
How long tires last (and which types wear faster)
All tires wear out, but some are built for longevity while others trade life for performance or capability.
Seasonal sets: If you swap summer and winter tires, still follow the 6‑year age guideline—even with proper off-season storage.

Cost to replace tires
Prices vary by size, type, and brand. As a broad estimate, many complete sets land around $600–$700, with a wide range above and below.

Replacing two tires vs. four
AWD/4WD: Replace all four to protect your drivetrain.
FWD/RWD: If replacing two, mount the new pair on the rear axle for stability. Details: Replacing two tires.
Best practice: A full set of four delivers the safest, most consistent performance.
TPMS and alignment with new tires
TPMS service: We inspect sensors and batteries, and can install new sensors (including retrofit kits for older vehicles). Learn about TPMS and correct air pressure.
Alignment: You may or may not need one with new tires. If your old set shows uneven wear or you’re upsizing wheels/tires, it’s smart to align. Many locations now offer wheel alignment. See stores with alignment: Find alignment locations.

Should you buy Tire Protection Certificates?
Tire Protection Certificates are optional coverage you can add at purchase. They’re a good fit if you:
- Drive in areas with potholes, construction, or debris
- Have low-profile, performance, larger-diameter, or higher-cost tires
- Rely on one vehicle for long commutes or family travel
- Want predictable costs if a tire is damaged beyond repair
If you mainly drive short distances on well‑maintained roads with a low risk of hazards, you may choose to skip it. Ask your store for current pricing and terms so you can weigh cost vs. peace of mind.
Services offered: Tire and wheel installation, free air checks, free rotations, free flat repair, free inspections, TPMS services, tire balancing, road-force balancing (where available), and wheel alignment at select stores. Many areas also offer mobile installation.
