bolts for steel wheels vs aloy wheels

[carv6441]

Hi everyone, just in the process of putting on my winter tyres (on steel wheels) and replacing the summer tyres (on aloy wheels). Very confused, and getting different answers, on if I should be using different bolts on the steel wheels? at the moment I have the original SAAB bolts part no. 92152366

thanks in advance for your help.

I believe this is just if you have had steel wheels on all the time...It seems that there is a way that road grime can build up to a point where is will stress out your bolts, and they should be replaced...

If you have the newer wheel bolts with the loose cone shaped washer, then you are fine. Just be sure to clean the hub surface thoroughly with each winter/summer tire & wheel change to remove the corrosion mentioned in the TSB that Al referenced.

If you have the old style bolts with a cone shaped collar machined integral with the head or shank, then you need to buy the new bolts. The new bolts are to be used with both the steel and aluminum wheels.

I had the same question last week, but figured that the bolts on my 2003 Wagon were the latest and safe to use on my steelie winters.

Enjoy the season.

BMW bolts also work and are extremely resistant to corrosion. Febi also makes replicas or they may be the OEM supplier, not sure which.
