How wheel size changes the cost of Mercedes-Benz GLC tyres

The cheapest Mercedes-Benz GLC fitment to re-tyre is 235/60 R18 103V (X253) at about £551 for a mid-range fitted set; the dearest is 235/50 R20 104W XL with 255/45 R20 105W XL rears (X253) at about £785 — 1.4 times as much.

That is 2 inches of rim, about £117 more per set for each extra inch.

1 of the 5 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.

Choosing premium over mid-range brands moves the most expensive set from £785 to £999.

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.
