It's time to change over to the summer tires. I bought a set of new W213 10-spoke wheels. They are what I could get for a sensible price, but are 7.5" wide rather than the 8.0" originals. They are also 40mm offset rather than the 48mm of the originals - OK for the original tire size and will move about 2mm outboard.
The question is, how long should the wheel bolts be. My originals are ~35mm thread length. I'm ready to order a set of 43mm long ones. I can't find out for sure if the W213 are 43mm or 45mm long. Moreover, I don't know if there is a danger of interference with too long a bolt on the W212 with W213 wheels. Hedging my bets with the 43mm instead of 45mm.
As for bolt length, it is easy.
Install the bolt on the rim/wheel ( not on the car yet ) and see how long does the bolt thread protrude out ?
The wheel bolt spare length or protrusion must be : Disc Rotor thickness ( in green ) + thread depth of the HUB (in pink ) and add 5mm more. You are gold.
Too long a bolt for rear tire is dangerous, as there are parking brake mechanism hidden inside the rotor disc.
