Found a nice set of 17" artillery wheels for a good price. My 38 has 16" wheels, which means new tires and tubes if I decide to buy the wheels. Add in sandblast and paint,mount and balance - you get the picture!! My question is on tires. I can probably get close to factory diameter with both radial and bias ply, but considering the artillery wheels are very narrow, which do you think would work the best?
