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

The cheapest Mercedes-Benz CLA fitment to re-tyre is 225/45 R17 91W (C117) at about £396 for a mid-range fitted set; the dearest is 225/40 R19 93Y XL (C118) at about £612 — 1.5 times as much.

That is 2 inches of rim, about £108 more per set for each extra inch.

Choosing premium over mid-range brands moves the most expensive set from £612 to £782.

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.
