What the defaults give
A $600 set with a 50,000 mile tread life costs $0.012 a mile.
At 12,000 miles a year that is $144 a year, and the set lasts about 50 months.
The formula
Cost per mile = set price ÷ tread life in miles
Annual cost = cost per mile × annual miles
Months of life = tread life ÷ annual miles × 12
Price is for a fitted set of four. If you are quoted per tyre, multiply by four first, and include fitting, balancing, valves and disposal if the shop charges them separately.
Worked examples
$600 / 50,000 mi → $0.012/mi, $144 a year
$800 / 60,000 mi → $0.013/mi, $160 a year
$400 / 40,000 mi → $0.010/mi, $120 a year
$1,200 / 70,000 mi → $0.017/mi, $206 a year
$600 / 50,000 mi at 20,000 mi a year → $240 a year, 30 months
$600 / 30,000 mi → $0.020/mi, $240 a year
Cheap tyres are not always cheaper
The interesting comparison is cost per mile, not sticker price. A $400 set that lasts 25,000 miles costs $0.016 a mile; a $700 set that lasts 60,000 costs $0.0117, so the dearer set is cheaper to run by about a third. The same logic applies to a set that wears unevenly because the alignment is out — a $600 set destroyed in 20,000 miles has cost three cents a mile.
Tread life ratings are a manufacturer claim tested on a controlled course, not a promise for your driving. Heavy acceleration, cornering hard, running under-inflated, and hot climates all shorten real life. Rotating every 6,000 to 8,000 miles and checking pressures monthly is what makes the rated number achievable.
What the cost per mile leaves out
It excludes fuel economy, which changes with rolling resistance by a few percent between tyre models, and it excludes the safety difference in wet braking, which is not a line item but is the reason the cheapest set is rarely the best value. It also excludes the cost of a second set if you run winters, where the annual figure should be split across both.
Replace tyres when tread reaches 2/32 inch, or earlier in wet climates where aquaplaning risk rises sharply below 4/32. Age matters too: rubber hardens, so a set with plenty of tread but six years on it should be inspected for cracking even if the mileage looks fine.
Frequently Asked Questions
How much do tyres cost per mile?
About 1.2 cents a mile for a $600 set rated at 50,000 miles. Divide the set price by the tread life to get the figure.
How long will a set of tyres last?
At 12,000 miles a year, a 50,000 mile set lasts roughly 50 months. Higher annual mileage shortens that in years, though the per-mile cost stays the same.
What is the annual tyre cost at 12,000 miles?
$144 at 1.2 cents a mile. At 20,000 miles a year the same set costs $240 a year and needs replacing in 30 months.
Are cheaper tyres better value?
Often not. A $400 set lasting 25,000 miles costs 1.6 cents a mile, while a $700 set lasting 60,000 costs 1.17 cents, so the dearer set is cheaper to run.
When should tyres be replaced?
At 2/32 inch of tread as a legal minimum, and sooner in wet climates. Rubber also ages, so inspect a six-year-old set for cracking even if tread remains.
