How wheel size changes the cost of BMW 3 Series tyres

The cheapest BMW 3 Series fitment to re-tyre is 205/60 R16 92V run-flat (F30/F31) at about £601 for a mid-range fitted set; the dearest is 225/45 R18 95Y XL run-flat with 255/40 R18 99Y XL run-flat rears (G20/G21) at about £806 — 1.3 times as much.

That is 2 inches of rim, about £102 more per set for each extra inch.

4 of the 7 fitments are staggered (different front and rear sizes). Staggered tyres cannot be rotated between axles, so the driven axle usually wears out first and pairs are replaced separately.

7 fitments use run-flat tyres, which cost more to buy and to fit.

Choosing premium over mid-range brands moves the most expensive set from £806 to £875.

How often you pay depends on wear as well as price: car tyre cost explains how 73 Auto turns these prices into a yearly figure for a specific car.

Limitations

Factory sizes are from 73 Auto's fitment reference; rows from the editorial compilation are medium confidence and not individually verified against a manufacturer document. A car may have been fitted with other wheels since new: check the size on the tyre itself.
