I'll check the tire size on my 174BH baja tonight when I get home from work if that will help. As far as the step issue goes, those are pretty easy to replace for under $100. I have a friend that did an axle flip and replaced his steps without issue. The stock stabilizers on a baja are almost too short and I have to carry around wood anyways. I had one site where I had over a foot stacked under one of the stabs.
