Ride quality on Pirelli PZero Runflats on 20" 795M wheel and tire package

Vancouver_M440 · 08-03-2022, 02:17 AM

Been scratching my head about winter tire setups because I can't decide between going with a cheap replica set of 18s with snows and keeping my black 791M as my summers, or using them as my winter wheels and getting a set of 20s as much summers. I saw BMW sells the 20" 795M as a wheel and tire package with Pirelli Pzeros and from what I can tell they are run flat. I am really liking the ride of the 19s and I am a little worried how much worse the 20s are. I haven't ever had good experience with run flats neither so far as ride quality. Any one using this combo and can comment on stock 19s vs the M performance 795M 20s?

Yeah I have 19's all season non runflats and I was looking at that set of 795m 20" but with the MPS4s tires. I have a hard time dropping that much money on a full set when I like how my 791m ride and look... maybe I just need summer tires :-)

Not sure if u have the 8" front and 8.5" rear wheels or the 8" all the way around. I have the staggered setup on PS4S and they are really good. I don't have bad roads here in Vancouver but there are the odd potholes. I suspect the forged nature of the OEM 20s will survive them ok. Just curious on the ride degradation. I had run flats once on a Merc and it was definitely harsh over sharp small bumps.

Yes I'm in the 8' all around jet black. Looking at 1$200 to get 8.5 rears rims and 1200 for tires all around... so i'm in for 2400$ for upgrading the 791's or 3.5k-5K for 795's with tires.

I just got the m340 so not ready to go drop that much just yet :-)
