Are Expensive Tyres Cheaper per Mile: Premium vs Budget Worked Out per Mile

On this page, are expensive tyres cheaper per mile is the case in point: Premium versus budget tyres is a cost-per-mile question, not a price question: the dearer tyre is cheaper to run if it lasts proportionally longer, and the cheap tyre is dearer to run if it wears out quickly. The formula is cost per mile = price ÷ expected mileage, applied at the same assumed mileage to both tyres so the comparison is like-for-like, and this page works it through with example prices and a table of three example prices against three example mileages. Every price and mileage here is an example used to show the working, and no tyre's real-world mileage is stated as fact — it depends on driving, alignment, pressure and load — so the honest comparison uses a mileage measured on the actual car.

On this page, are expensive tyres cheaper per mile is the case in point: The worked example makes the point: a £90 tyre over an assumed 30,000 miles costs 0.30 p per mile, while a £180 tyre over the same 30,000 miles costs 0.60 p per mile. If the dearer tyre lasts 40,000 miles instead of 30,000, its cost per mile falls to 0.45 p — still dearer per mile than the cheap tyre at the same mileage, but the gap narrows, and the extra grip, wet performance and quietness may be worth it. The sections below cover the formula, the table, the factors that move mileage, and how to measure your own wear rate so the comparison uses real figures.

The cost-per-mile formula for are expensive tyres cheaper per mile

For are expensive tyres cheaper per mile, the point is this: Cost per mile = tyre price ÷ expected mileage. For a single tyre, divide the price of one tyre by the miles it is expected to cover. For a set of four, the cost per mile is (4 × tyre price) ÷ expected mileage, which is four times the single-tyre figure. The result is usually expressed in pence or cents per mile: a tyre costing £130 over an assumed 30,000 miles gives £130 ÷ 30,000 = £0.0043, or 0.43 p per mile. The mileage in the formula is the uncertain half — it is an assumption or a measurement, never a guaranteed property of the tyre — so the worked example below states its assumptions plainly, and the section on measuring wear shows how to replace the assumption with a figure measured on the actual car.

are expensive tyres cheaper per mile: What cost per mile means

Taking are expensive tyres cheaper per mile as the case in point: Tyre cost per mile turns two numbers — the price and the mileage — into one number that can be compared across tyres, vehicles and budgets. The formula is cost per mile = tyre price ÷ expected mileage, and for a set of four tyres the total is (4 × price) ÷ mileage. A result of 0.5p per mile means each mile of driving wears away half a penny of tyre value, and the table below shows how that figure moves when the price or the mileage changes. The prices and mileages in this article are examples, labelled as such, because no tyre's real-world mileage can be stated as a fact: it depends on driving style, alignment, inflation pressure, load and the roads the car uses.

Worked example: £130 over 30,000 miles for are expensive tyres cheaper per mile

Taking are expensive tyres cheaper per mile as the case in point: Take a tyre priced at £130 as an example, with an assumed life of 30,000 miles. The cost per mile for one tyre is £130 ÷ 30,000 = £0.0043, which is 0.43 p per mile. A set of four costs £520 and lasts the same 30,000 miles, so the cost per mile for the set is £520 ÷ 30,000 = 1.73 p per mile. Over 10,000 miles of driving, the set costs 173.33 £ in tyre wear; over 12,000 miles a year it costs 208.00 £ a year. If the same tyre lasted 40,000 miles instead of 30,000, the cost per mile for the set would fall to 1.30 p; if it lasted only 20,000 miles, it would rise to 2.60 p. Both the price and the mileage are examples, labelled as such, and the mileage is the figure that matters most because it is the one that varies most between drivers.

Taking are expensive tyres cheaper per mile as the case in point: All prices and mileages are examples used to show the working. Read across for the mileage and down for the price.

Tyre price (example) 20,000 miles 30,000 miles 40,000 miles
£90 0.45 p per mile 0.30 p per mile 0.22 p per mile
£130 0.65 p per mile 0.43 p per mile 0.33 p per mile
£180 0.90 p per mile 0.60 p per mile 0.45 p per mile

On this page, are expensive tyres cheaper per mile is the case in point: The table shows the two directions of the formula at once: moving right along a row, the cost per mile falls as the mileage rises, and moving down a column it rises as the price rises. A £90 tyre over 20,000 miles costs 0.45 p per mile, while the same tyre over 40,000 miles costs 0.22 p — the same tyre, the same price, and a very different cost per mile, decided entirely by how long it lasts. That is why the mileage deserves more attention than the price: it is the bigger lever, and it is the one the driver can influence by the way the car is driven and maintained. Compare tyres at the same assumed mileage so the comparison is like-for-like, and use a measured wear rate where one is available.

are expensive tyres cheaper per mile: What decides how long a tyre lasts

For are expensive tyres cheaper per mile, the point is this: Mileage is the uncertain half of the formula, and it is moved by several factors that are worth knowing before any comparison is made. Driving style matters most: hard acceleration, heavy braking and fast cornering wear the tread faster than smooth driving. Alignment matters next: a car that scrubs its tyres through a corner wears one edge of the tread and shortens the tyre's life. Inflation pressure matters too: under-inflation wears the shoulders and overheats the tyre, while over-inflation wears the centre. Load, road surface and temperature all play a part, and the tyre's own construction and compound set the starting point. Because so many factors move the mileage, the honest way to use the formula is with a mileage you have measured yourself — from the tread depth and the miles driven — rather than a figure quoted for the tyre.

How to measure your own tyre mileage for are expensive tyres cheaper per mile

The way to get a real mileage figure is to measure tread wear over a known distance. Record the tread depth with a gauge when the tyres are fitted and the odometer reading at the same time. After several thousand miles, measure again: the wear rate is the depth lost divided by the miles driven, and the remaining life is the depth left above the legal minimum divided by that wear rate. The legal minimum is 1.6 mm in the UK and 2/32 inch in the USA — jurisdiction-specific figures that change, so check the current limit where the car is used. That measured wear rate is the honest input to the cost-per-mile formula, and it is far more useful than any mileage quoted for the tyre, because it reflects the actual car, the actual driving and the actual roads. That is the point this page works through for are expensive tyres cheaper per mile.

are expensive tyres cheaper per mile: Common mistakes with cost per mile

On this page, are expensive tyres cheaper per mile is the case in point: Mistakes in cost-per-mile calculations are usually about the inputs. The first is using the purchase price without the fitting cost, which understates the true cost — include fitting, balancing and any disposal charge if they are part of what was paid. The second is using a mileage figure quoted for the tyre as if it were measured on the car; real mileage depends on driving, alignment, pressure and load, so a measured wear rate is the honest input. The third is comparing two tyres at different mileages, which rigs the comparison — hold the mileage the same for both and let the price do the talking. The fourth is forgetting the set: a car needs four tyres, so the cost per mile for the set is four times the single-tyre figure. And the fifth is treating the result as the whole running cost, when fuel, insurance and servicing are usually larger lines.

Frequently asked questions

Are expensive tyres cheaper per mile?

Taking are expensive tyres cheaper per mile as the case in point: They can be, if they last proportionally longer. A tyre that costs twice as much and lasts twice as long costs the same per mile, and one that lasts more than twice as long costs less per mile. Work the formula out at the same assumed mileage for both tyres — the table above shows how — and judge the extra grip, wet performance and quietness alongside the per-mile figure.

Are budget tyres false economy?

On this page, are expensive tyres cheaper per mile is the case in point: Not always. A budget tyre that lasts well can be the cheapest per mile, and a premium tyre that wears quickly can be the dearest. The price on the shelf does not answer the question; the price divided by the mileage does. Use a measured wear rate where one is available, and compare like-for-like at the same assumed mileage.

What should I compare besides cost per mile?

Taking are expensive tyres cheaper per mile as the case in point: Grip in the wet, braking distance, noise, comfort and handling all matter, and none of them shows up in the cost-per-mile figure. A tyre that is cheapest per mile but poor in the wet is not the right choice. Use cost per mile for the value comparison and the tyre's performance for the safety comparison.

How can I make my tyres last longer?

Keep pressures at the placard figure, checked cold; have the alignment checked when the tyres show uneven wear; drive smoothly instead of accelerating hard and braking late; avoid overloading the car; and rotate the tyres if the manufacturer recommends it. Each of these extends the mileage in the formula, which cuts the cost per mile directly. That is the point this page works through for are expensive tyres cheaper per mile.

What is the legal minimum tread depth?

For are expensive tyres cheaper per mile, the point is this: In the UK the legal minimum tread depth is 1.6 mm across the central three-quarters of the tread, and in the USA it is 2/32 inch. Both are jurisdiction-specific limits and they change, so check the current figure where the car is used. Most drivers replace tyres before the legal minimum, because wet grip falls off well before the tread is bare.
