buy the right tool for the job. i have the 4s on my E46 M3 and they are great...but only for warm weather use. i wouldnt trust the summer compound under cold conditions...its not worth the risk. under lower temps that rubber will turn rock hard and provide poor traction. def to A/S if you need an all-year tire.
These should help in your decision. Seems pretty clear not to get them cold. Not just for the possibility of lowered performance while driving, but actual safety in normal temp ranges after cold temperature exposure.
I have an unconventional view on that.
The public feel secure in the passive safety envisioned in driving a truck, perhaps only true when others loose control or if one is prone to distracted driving.
I believe active safety is more important.
Trucks are a terrible conveyance for accident avoidance, longer braking distance, much slower response to demands in direction change.
The lower center of gravity of the e60 chassis is conducive to keeping the shiny side up regardless of scenarios
I would rather ride a Bus than have my control inputs attenuated by a Truck.
