Short post to share my experience installing 4 winter tires today on my M3 at my local garage.
Tires: Michelin Pilot Alpin 5 235/40 R19 96W XL
I kept my original 19" wheels
Ordered the M3 lift pods here:
The only issue today was with the pods. They are a bit thick, so their 4 arm lift could not fit underneath the pod, especially up front. They could not remove the support from the lift and could not lower it enough to slide the support under the pod. We thought we could lay the pod on the arm of the lift, but even that proved impossible, we could not slide the arm, it was touching the pod. Not much was missing, but it could not be done. So we moved the car to a flat lift (just 2 flat plates flush with the garage floor) and we could lift the M3 with the 4 pods in place.
The rest went smoothly. The guy made me aware that the torque needed to tighten the nuts was higher than usual, 180 N-m, i believe this is around 130 ft-lb.
So might be a good thing to check the lift your garage is using if you want that job done.
