How wheel size changes the cost of Audi A6 tyres

The cheapest Audi A6 fitment to re-tyre is 225/55 R17 101W XL (C7) at about £493 for a mid-range fitted set; the dearest is 255/40 R20 101Y XL (C8) at about £729 — 1.5 times as much.

That is 3 inches of rim, about £79 more per set for each extra inch.

Choosing premium over mid-range brands moves the most expensive set from £729 to £901.

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.
