The Cheapest Tire Is Rarely the Lowest Cost: Buying by Cost per Mile
Divide a tire's price by the miles it actually delivers and the picture flips: a $165 tire that runs 55,000 miles costs $3.00 per 1,000 miles, while a $120 tire that runs 30,000 costs $4.00. The "cheaper" tire is 33% more expensive to operate.
The only number that hits the P&L
Sticker price is paid once. Miles are what you sell. Cost per mile = price ÷ tread life, and it's how every serious fleet buys rubber.
A worked example
| Tire A | Tire B | |
|---|---|---|
| Price | $120 | $165 |
| Tread life | 30,000 mi | 55,000 mi |
| Cost / 1,000 mi | $4.00 | $3.00 |
Tire B costs $45 more at the counter and 25% less every mile after that. Across 18 tire positions running 100,000 miles a year, that difference is about $1,800 per year — from one line-item decision.

Where tread life numbers come from
Your own scrap records beat everything: miles-at-removal is the gold standard. No records yet? Start from the manufacturer's mileage warranty and your dealer's experience with the line, then refine.
Don't forget the fuel side
Underinflated and worn-out tires raise rolling resistance, and fuel dwarfs tire spend on most trucks. Tire pressure discipline is fuel money — see how temperature moves your PSI. Ready to price a program? Request fleet pricing.
