How to use this calculator
Enter the details for each tire option you are considering. Start with the price per tire, the number of tires on your vehicle (18 is the default for a standard semi), and the expected tread life in miles. If the tire can be retreaded, check the retread box and enter the retread cost and expected retread life.
The calculator instantly computes the cost per mile for each option, including a blended cost per mile that averages original and retread life cycles together. The cheapest option per mile is highlighted so you can see the best value at a glance. You only need to fill in the options you want to compare.
Why cost per mile matters more than sticker price
Sticker price is the most misleading metric when buying truck tires. A cheaper tire that wears out faster will cost you more in the long run because you replace it sooner and pay for mounting, balancing, and downtime more frequently. Cost per mile normalizes the comparison by accounting for how long each tire actually lasts.
For a truck running 120,000 miles per year, even a $0.01 difference in tire cost per mile adds up to $1,200 annually. Across a fleet of 20 trucks, that is $24,000 per year. Small per mile differences become significant operating expenses at scale, which is why fleet managers and owner operators who track this number consistently spend less on tires over time.
New vs. retread tire economics
Retreading is the process of applying new tread rubber to a worn tire casing. A quality retread costs roughly 30% to 50% of a new tire price while delivering 70% to 85% of the original tread life. This makes retreads one of the most effective ways to lower your tire cost per mile, especially on drive and trailer positions.
The blended cost per mile in this calculator combines the original tire life and the retread life into a single number. For example, a $450 tire lasting 100,000 miles followed by a $200 retread lasting 80,000 miles gives a blended cost of ($450 + $200) x 18 tires / (100,000 + 80,000) miles = $0.065 per mile. Without the retread, the same tire costs $0.081 per mile. That retread cycle saves roughly 20% on tire costs.
Tire maintenance tips to maximize tread life
Proper inflation is the foundation of tire longevity. Check pressure at every fuel stop when tires are cool. Both overinflation and underinflation cause uneven wear patterns that shorten tread life. Use a calibrated gauge and follow the tire manufacturer specifications for your load weight.
Alignment and suspension condition directly affect how evenly your tires wear. Misaligned axles cause scrubbing that can cut tire life in half. Have alignment checked every 50,000 miles or whenever you notice uneven wear. Rotating tires between positions (where applicable) also helps distribute wear more evenly and extends the overall set life.
Frequently asked questions
What is a good cost per mile for truck tires?
Commercial truck tires typically range from $0.03 to $0.06 per mile depending on position, brand, and retread usage. Steer tires tend to cost more per mile due to premium pricing, while drive and trailer positions can be lower when retreads are part of the equation.
How much can retreading save on tire costs?
Retreading can reduce your blended tire cost per mile by 20% to 35%. A retread typically costs $150 to $250 versus $400 to $600 for a new drive tire, while delivering a substantial portion of the original tread life.
How many miles should commercial truck tires last?
Steer tires typically last 100,000 to 150,000 miles. Drive tires last 80,000 to 120,000 miles. Trailer tires can go 100,000 to 150,000 miles. Actual results depend on tire quality, inflation habits, load weights, and road conditions.
Should I buy premium tires or budget tires?
Let cost per mile decide. Premium tires often last significantly longer and offer better fuel efficiency, which can make them cheaper overall. A tire that costs 30% more upfront but lasts 50% longer is the better deal. Use this calculator to compare your actual options.
