Mercedes SL-Class tyre options at Tyres.co.uk include Michelin Pilot Sport 5 and Pirelli P Zero 255/40 R18 99Y XL for the 2008 SL 280, SL 350, and SL 500 with factory 18-inch square fitment. This exceeds the original 95W requirement; confirm the registration, as other wheel options may be staggered or run-flat.
The Mercedes SL-Class tyre information placard can be found on the driver's side B-pillar, and is visible when the door is open. The tyre pressure table is found inside the fuel filler flap, and the full size, load index and speed ratings are moulded on each sidewall of the tyres. Please confirm the fitted wheel option, as SL-Class specifications can vary.
It is not typical for all four tyres to be replaced on Mercedes SL-Class models; replacement is done in pairs per axle, and factory staggered front and rear sizes should be retained. Earlier generations of the SL-Class are rear-wheel drive, but it is necessary for the R232 SL 55 and SL 63 4MATIC+ to have an approved matching tyre combination on all axles. When replacing two tyres, the new tyres are to be fitted to the rear axle.
