Tires wear with every mile, so they belong in the cost per mile just like fuel. Owners who skip them see a good margin on paper, then face a large bill all at once.
Do the math by position
Steer tires usually cost more and are replaced sooner than drive and trailer tires. Price each position, divide by the miles you expect from it, and add them up for a tire cost per mile.
Make them last
- Check pressure regularly; underinflation is a leading cause of early wear and blowouts.
- Watch alignment; uneven wear on steer tires is a warning sign.
- Inspect tread and sidewalls on every pre-trip.
- Consider retreads for drive and trailer positions where they make sense.
Set the money aside
Multiply the tire cost per mile by the miles each week and move that amount to a maintenance fund.
