How wheel size changes the cost of Porsche Cayenne tyres
The cheapest Porsche Cayenne fitment to re-tyre is 255/55 R18 109Y XL (Cayenne 92A) at about £598 for a mid-range fitted set; the dearest is 285/35 R22 106Y XL with 315/30 R22 107Y XL rears (Cayenne E3) at about £949 — 1.6 times as much.
That is 4 inches of rim, about £88 more per set for each extra inch.
3 of the 6 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 £949 to £1,351.
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.
