My 435 came with run-flats and I hated them. I'm a moderate driver, age 71, and have manual transmission and RWD configuration.
The Pirelli run-flats only lasted a bit over 20K miles. Terrible!
So I installed a set of conventional tires. Now I need to consider the flat tire scenario.
I'm looking for a donut solution ("space saver spare"). I would only carry the spare when traveling out of the metro (Denver) area. I have a suitable scissors jack, but I am looking for a used BMW donut wheel which could be mounted in my 4-series coupe. Does anybody know which other BMW models have: 1) the same bolt pattern, and 2) a similar donut tire diameter?
Has anyone else engineered this solution to eliminating their run-flats?
Thanks.
