What is the offset? Zero or close to zero is required as I understand it.
I've looked at mine wonder if I could go to 14 inch wheels. I think there is a part of the shell / wheel well forward of the wheel on the starboard side that will be too close. That could be trimmed off however. The other issue is the aging of the torsion
axle. Even if there is enough clearance for the tire now, that does not guarantee they will be in the future.
Part of my looking at this was reading many prior posts on the subject. The info seemed to be mixed however.
