I have 59 firetruck that I plan to convert from steel 10 lug original steel wheels to 10 lug aluminum wheels. Some of the members may remember seeing my truck before on this site. I know that the lug studs need to be longer since the aluminum wheels are thicker than the original steel wheels. My thinking is that the front studs have to be changed to longer studs and the rears could be used as is if I use a steel inter wheel and use longer studs for the outer. If anyone has made this swap let me know if my thinking is correct. Any other comments about this swap is welcome. thanks Geary
