How much are semi truck tires? Prices, retreads and cost per mile

Tires are one of the largest running costs on a truck after fuel. The sticker price of one tire tells only part of the story. What a tire really costs depends on how many miles it delivers, whether its casing can be retreaded, and what it does to fuel economy. This guide covers what drives the price and how to compare tires on what they actually cost you.

What goes into a tire bill

Tap each part of the bill to see what it covers.

Price by position

• Steer tires carry the front of the truck and need precise handling. Premium steer tires are often among the most expensive tires on the truck, and most owners keep new tires, not retreads, on the steer axle.
• Drive tires have deeper tread for traction and often cost as much as or more than steer tires. They are often retreaded. Our guide to the best drive tires for a semi truck covers what to look for.
• Trailer tires are usually the least expensive per tire, but there are many of them. Retreads are common here.

Price by brand tier

Commercial tires are often grouped into premium lines from the major makers, mid-tier lines and budget lines, often imported. Premium tires usually cost more but often deliver more miles, better fuel economy and stronger casings for retreading. Budget tires cost less up front and can make sense for some uses, such as trailers that see light duty, but may cost more per mile if they wear faster or cannot be retreaded.

Size and type

Tire size changes price. Common sizes such as 295/75R22.5 and 11R22.5 are widely available and competitively priced. Wide-base singles cost more each but replace two dual tires. Low-profile and specialty sizes can cost more and be harder to find on the road. Our guide to semi truck tire size explains the common sizes and how to read them.

New vs retread

A retread puts new tread on a used casing. It typically costs much less than a new premium tire and can deliver many miles when done on a sound casing by a reputable retreader. Retreads are widely used on drive and trailer positions by fleets of every size. The key is casing quality: a premium casing designed for retreading can be retreaded more than once, which spreads its original cost over many more miles.

The full set

A standard tractor-trailer runs 18 tires: 2 steer, 8 drive and 8 trailer. Replacing all of them at once is rare. Positions wear at different rates and are replaced as needed. Budgeting by position, with retreads on drive and trailer tires, gives a far more realistic yearly tire cost than multiplying one price by 18. Our guide to semi truck tires covers positions and the federal tread rules.

Weight and wide-base savings

Tires and wheels are heavy. Wide-base singles and aluminum wheels can save weight, which can be worth money in payload for trucks that haul heavy freight. Our guide on how much a semi truck weighs shows how the empty weight adds up.

Judging tires on cost per mile

The fairest comparison is cost per mile:

Cost per mile = (tire price + retread costs - casing credit) / total miles from new tread plus retreads

A tire that costs 30 percent more but lasts 50 percent longer is the cheaper tire. A tire that can be retreaded twice can beat a cheaper tire that is scrapped after one tread. The tire cost per mile calculator does the math for steer, drive and trailer positions, including retreads.

Ways to lower tire costs

• Keep pressures right. Underinflation is the leading cause of early wear and failures.
• Watch alignment. Misalignment wears tires fast.
• Match duals in size and tread depth.
• Retread good casings on drive and trailer positions.
• Plan replacements before tires reach the limit, so you buy at a shop instead of on the roadside.
• Keep records by tire and position to see which lines perform best on your truck.

Price quotes: what to ask

• Is the price per tire mounted, or tire only?
• Are valve stems, balancing and disposal included?
• What is the casing credit, and what condition must the casing be in?
• What warranty comes with the tire, and what voids it?
• What does emergency road service cost in the areas you run?

An EXAMPLE yearly tire budget

Here is an EXAMPLE yearly tire budget for one tractor-trailer running about 110,000 miles. Every figure is a placeholder; replace them with your quotes and records.

• Steer tires: 2 new tires a year at a premium price, replaced well before the legal limit.
• Drive tires: 8 tires lasting more than a year, with one retread on each good casing.
• Trailer tires: 8 tires, mostly retreads, replaced as they wear or are damaged.
• Repairs and road service: a few punctures repaired at a shop, plus one roadside call.

Add these up and divide by 110,000 miles, and the result is a tire cost per mile you can put into your rates. Track the real numbers for a year and your budget becomes much more accurate than any rule of thumb.

Where to buy truck tires

• Commercial tire dealers offer the widest choice, mounting, retreading and road service, often with fleet pricing.
• Truck stop tire shops are convenient on the road, especially for emergencies, but prices can be higher.
• National account programs from tire makers and large dealer networks give small fleets access to set pricing and road service.
• Online sellers may offer lower prices on tires, but mounting, balancing and disposal still need a shop.

When cheaper tires make sense

Budget tires can be a reasonable choice in some cases:

• Trailers that sit a lot or run short distances.
• Trucks you plan to sell soon, where future retreads do not matter to you.
• Positions where tires are often damaged by job site conditions before they wear out.

For steer tires and long haul drive tires, most owners find premium tires deliver the lowest cost per mile once miles, fuel and retreads are counted.

Tire costs and fuel

Tires affect fuel economy through rolling resistance. Low rolling resistance tires, including those verified under the EPA SmartWay program, can save fuel over a year. On a long haul truck burning thousands of gallons, a small improvement in fuel economy can be worth more than the difference in tire prices. When comparing tires, include fuel in your thinking, not just tread life.

The cost of a roadside tire call

A tire failure on the road costs more than the tire. There is the call-out fee, after-hours labor, the tire itself at roadside prices, the time lost, and possibly a missed appointment. Planning tire replacements, keeping pressures right and checking tires at every stop are the best ways to avoid that bill.

Tire prices and inflation

Truck tire prices change with raw material costs, freight costs and demand. Prices you paid a year ago may not hold. Get fresh quotes when planning a replacement, and update your cost per mile when prices change.

Tire warranties and what they mean for cost

Commercial tire warranties usually cover defects in materials and workmanship, often prorated by the remaining tread. They rarely cover road hazards, underinflation damage, misapplication or wear from mechanical problems such as poor alignment. When comparing prices, read what each warranty actually covers and what it requires, such as proof of regular pressure checks. A warranty you can never use adds no value.

Casing value

A good casing has value even when its tread is worn out, because it can be retreaded. Many dealers give a credit for casings in good condition, or retread your own casings for a lower price than a new tire. That makes casing care part of tire cost: avoiding underinflation, impact damage and running tires down too far keeps casings retreadable. Damaged casings have no retread value and become scrap.

Asking for a quote that compares fairly

When asking two dealers for prices, give both the same details: tire size, load range, position, quantity, whether you want new or retread, and whether mounting, balancing, valve stems and disposal should be included. Ask both for the casing credit and warranty terms. That way you compare the full cost, not just the tire price.
