New to MB - question about tires
We recently bought a 2019 E450 and were surprised to learn at delivery that it had run flat tires. I guess I asked the wrong question in confirming that the tires are all-season! At any rate, hoping for some help and advice from the forum.
If I switch to regular (non-RF) tires, can the spare be a donut or would MB only support a full spare?
if donut works, would it fit in the compartment under the floor of the trunk?
if I stick with run flat tires I am considering getting a full sized spare for long trips - can an all-season tire be used as a spare with run flat snow tires or do you effectively need two spares - an all-season RF and a snow RF?
Finally, if I get snow tires, is it really better to have dedicated wheels or fine to switch between all-season and snows on MB OEM wheels?
Thanks in advance!
