I've managed to locate a unicorn - 2014 CD with air suspension and only 22K miles, delivers to me next Wednesday!

I'm replacing my 2019 Chevy ZR2 so would like to upgrade the tires to something more mild off-road friendly. I've seen threads referencing running lifted steel suspension to run 265/65R18 tires successfully (including Joey Seely's builds).

I think a 65 aspect ratio is not going to fit stock, so is anyone running 265/60R18 tires like a Wrangled Duratrac, Bridgestone KO2, or my preference, Falken Wildpeak AT3W with air suspension?

If so, were any changes required to caster, or modification of the shock mounts or software reprogramming required?

So. 265/60R18's will fit with stock air suspension geometry. Specifically these are Falken Wildpeak AT3W (OEM fitment for 2020 G-wagen), on stock 18x8 wheels. This photo is at Normal height, no rubbing at full lock. Thanks @JCope for sharing tire sizes on your truck.

Hey, thanks for this thread. Exact same question but a Cayenne 958 without air suspension

Do you think it'll fit 265/60R18 will fit it the same way as on your air suspension 958?

Also looking to get Falken Wildpeak AT3W and that's the minimal size they have in chart for R18.

I'm also worried about snow and ice buildup with this height profile vs stock 55, seems like it can be a problem..

Thanks for advice!
