RESULT · TIRE COST PER MILE

Tire cost per mile result
Steer (2 tires)	1.00 cents/mi
Drive (8 tires)	1.60 cents/mi
Trailer (8 tires)	1.60 cents/mi
Total tire cost per mile	4.20 cents/mi
Per 100,000 miles	$4,200

Show the math

Cost per position = tires x (new price + retread price x retreads)
Miles per position = new miles + retread miles x retreads
Cost per mile = cost / miles; total = sum of positions

Tires cost you about 4.20 cents/mi. That belongs in your floor rate, and we negotiate above it at 5% of gross.

Start dispatch

This tire cost per mile calculator returns your tire cost per mile for steer, drive and trailer positions and the total for the truck, including retreads.

Tires are one of the larger running costs for a truck after fuel, and they are easy to underprice because the bill comes all at once. Turning that bill into cents per mile puts it where it belongs: in your cost per mile and your floor rate.

How it works

For each position:

Cost = number of tires x (new tire price + retread price x retreads per casing)
Miles = miles per new tire + miles per retread x retreads per casing
Cost per mile = cost / miles

The total is the sum of the three positions, shown in cents per mile and per 100,000 miles. Prices and mileages in the calculator are EXAMPLE values. Use your invoices and your own records.

A worked example

Using the EXAMPLE defaults for a tractor and trailer:

Steer: 2 tires at $600, 120,000 miles, no retreads: $1,200 / 120,000 = 1.0 cent per mile
Drive: 8 tires at $550, 250,000 miles, plus one retread each at $250 for 150,000 miles: $6,400 / 400,000 = 1.6 cents per mile
Trailer: 8 tires at $450, 200,000 miles, plus one retread at $250 for 150,000 miles: $5,600 / 350,000 = 1.6 cents per mile
Total: about 4.2 cents per mile, or about $4,200 per 100,000 miles

A box truck or straight truck has fewer tires, so the numbers will be lower; enter your own counts.

What tires cost

Prices vary by size, brand, position and tread type. Our guide on how much semi truck tires cost covers typical price ranges and what changes them. Mounting, balancing, valve stems and disposal fees add to the bill, so include them in the price per tire.

Getting the most miles

Inflation. Check pressure regularly with a calibrated gauge, cold. Underinflation is one of the biggest causes of early wear and failures.
Alignment. Misalignment wears steer and drive tires quickly and unevenly.
Matched duals. Keep dual pairs close in size and tread depth.
Speed and driving. Hard braking, fast cornering and high speed all wear tread.
Casing care. A damaged casing cannot be retreaded, which raises the cost per mile.

Track tread depth as tires wear; our guide to commercial truck tire tread depth covers how to measure and what wear patterns mean.

Using the result

Tire cost per mile is one line in your cost per mile. Put it in the trucking cost per mile calculator with fuel, maintenance and fixed costs to see your full floor rate, then compare loads against it with the rate per mile calculator.

Keeping tire records

The calculator is only as good as the miles per tire you enter. Keep a simple record for each tire: position, brand and size, date and odometer when it went on, tread depth readings over time, and the date and odometer when it came off and why. After a set or two, you will know what your tires actually deliver on your lanes, which beats any advertised mileage.

Box trucks and straight trucks

A box truck or straight truck has fewer positions: usually two steer tires and four or more drive tires, with no trailer. Enter zero trailer tires and adjust the counts. Local work with many stops and tight turns can wear tires faster than highway miles, so your miles per tire may be lower than a tractor's on the highway.

Road service costs

A tire failure on the road costs more than the tire: the service call, the time and sometimes a missed delivery. Running tires to the very limit can look cheap per mile and end up expensive. Many owners replace a little early and treat the unused tread as the price of avoiding a roadside call.

Planning tire replacement

Tire replacement is easier to plan than to react to. When a position gets close to its replacement point, book the shop and plan the load before so the truck finishes near the tire shop you trust. A planned tire stop costs far less than a roadside tire call.

Where we fit

We dispatch 26 ft box trucks and larger across 11 equipment types. We find and negotiate loads, you say yes, counter or no, and the broker sends the rate confirmation to you to sign. How this works for one truck is on our owner-operators page.

Questions

How do I calculate tire cost per mile?

For each position, add the cost of the tires, including mounting and any retreads, and divide by the total miles they will run. Then add the positions together. Steer, drive and trailer tires wear at different rates and cost different amounts, so working them out separately gives a more accurate total.

How long do semi truck tires last?

It varies with position, tire, load, speed, roads, alignment and inflation. Steer tires often wear out sooner than drive and trailer tires, and many fleets pull them earlier for safety. Use your own records: note the odometer when a tire goes on and when it comes off, and use those miles in the calculator.

Are retreads worth it?

Retreads can cut tire cost per mile on drive and trailer positions, because a good casing gets more miles for less than a new tire costs. They depend on sound casings and a reputable retreader. Many owners do not run retreads on the steer axle. The calculator shows the cost per mile with and without them.

What raises tire cost per mile?

Low inflation, poor alignment, overloading, high speed, aggressive braking and rough routes all wear tires faster. So do mismatched duals and damaged casings that cannot be retreaded. Checking pressure and alignment regularly is one of the cheapest ways to lower your tire cost per mile.
