What is your actual tire size (not the 32")?

I have to double check but I think I have 235/85r16s which are 31.7" tall with 3.73s.
All for not though as I will be putting the MG conversion on the gas van and most likely using 285/75r17s (I think....whatever the metric equivalent to 34" is). In that case, I would regear my new axles to 4.56s.
