I'm going from the original 15x19.5 R4 tires and wheels that came on my B3350HSD to 8.3 x 24 R1. I'm having the wheels made, but since most companies are closed due to Covid-19 I'm having a difficult time getting the right bolt circle and center bore. Yes I could measure the existing wheels myself, but I would rather someone knew the numbers already so I don't make a mistake sending to the wheel company. Any help?
