2020 M550 20" wheels- are F/R same width?
Hey folks, looking to swap out the OEM Summers with non-runflat all-seasons on a 2020 M550 and would prefer a square setup.
OEM tires are 245/35-20 F / 275/30-20 R. I'm fairly certain that both front and rear 20" wheels are same size, but wanted to make sure. Ideally I'd like to run 245/35 all around, rotate when needed, and squeeze out some additional life out of the new A/S's. Side question, how does the AWD system not get fried from overuse- the OEM rolling diameters with this set up are a quarter inch off? front side wall = 245 x 0.35 = 85.75mm rear side wall = 275 x 0.30 = 82.5mm 2 x 85.75mm - 82.5mm = 0.256" |

My vote goes to the Michelin PS3ZP, in my opinion a new revelation in runflats, which performs truly like a performance tire and rides smooth and quiet. Love mine. New tire, though, may be hard to get.
