Someone please tell me proper tires size for 18.8.5 & 9.5
Front: My AMG catalog shows a 225/40 was used with an 18x8.5 front (with a 25 offset). Brabus shows the same tire but the wheel offset was 30, and Carlsson used the same tire with a 35 offset.
Odd how the offsets are all over the place, but the catalogs are in agreement on the tire sizes. However, tire brands will matter. In double checking the Continental Tire catalog, the rolling circumferences of those tire sizes for a ContiSport Contact 2 would be a match. Ditto for Michelin PS2's. They wouldn't match on a Dunlop Direzza.
255.35.18fr./ 275.35.18 rear
photos(and explaination) in my post "What You Need To Know When You Buy a Used CLK"
Check it out. I have tried different sizes over the years and this is it.
This info is from EXPERIENCE. NOT a catalog.
BTY: offsets on my wheels are 33f/35r. But these vary depending on the Rim itself and how(and wether) it was made to fit this particular vehicle.
If your goal is to fill the wheelwells, it's 255, and 275.
