Set of four = two front and two rear tyres at the median price for that exact size, load index and speed rating, plus fitting, balancing, valves and disposal. — means too few market offers to price it.

How wheel size changes the cost of BMW 7 Series tyres

The cheapest BMW 7 Series fitment to re-tyre is 245/50 R18 100Y run-flat (G11/G12) at about £857 for a mid-range fitted set; the dearest is 245/40 R20 99Y XL run-flat with 275/35 R20 102Y XL run-flat rears (G11/G12) at about £954 — 1.1 times as much.

That is 2 inches of rim, about £48 more per set for each extra inch.

2 of the 3 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.

3 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 £954 to £1,102.

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.
