Hey there,

I recently purchased a 2019 M240i Xdrive Coupe with the M performance edition. the factory p zero rft and low sidewall are pretty bad in the shitty city I live in with all the potholes, etc.

I'm wanting to switch out the rft's for a set of Michelin PS4S that ofcourse is not RFT, But I'm also wanting to bump the sidewall up a little if possible.

I would like to keep the factory 19" wheels if possible but will get a set of 18" as a last resort.

Factory staggered tire sizes are
225/35R19 Front
245/30R19 Rear

I'm wanting to go to something like
225/40R19 Front
245 or 255/35R19 Rear

Does anyone know if this will work or not? it's about a 1" increase in overall diameter, puts my speedo out about 2.9 mph at 60 mph which i am ok with.

any advice would be greatly appreciated,
Thanks!
