How wheel size changes the cost of Mercedes-Benz SL tyres
The cheapest Mercedes-Benz SL fitment to re-tyre is 255/40 R18 99Y XL (R230) at about £708 for a mid-range fitted set; the dearest is 275/35 R21 103Y XL with 305/30 R21 104Y XL rears (R232) at about £1,094 — 1.5 times as much.
That is 3 inches of rim, about £129 more per set for each extra inch.
8 of the 9 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 £1,094 to £1,109.
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.
