Hi Dave,
Thanks for the input. I'm running 4.10's now with a limited slip. I didn't think I needed to go higher. But then again....the reason I'm on here is hoping to hear from someone who has already done this. Up here in North Jersey, you don't see any of these.
I'm looking for anyone who is running 22.5's with Semi tires on their dually. I am looking at different wheels and tires and would appreiate any info from somebody already running them. Currently I'm looking at the Amerian Force wheels with Sumitomo ST908's.
