It was time to replace the tires on my 52' 3100. I wanted to keep the truck original but have the advantages of new radial tires. After sandblasting, repainting, and mounting the new tires I found that the wheels are leaking in the area where the two separate pieces touch (these are two piece wheels, 15 x 5.5), or near where the rivets are. My question is has anyone had any luck sealing these wheels so that I can use tubeless tires. Original wheels are hard to find in good condition so I really don't know what to try next. Any advice is appreciated, thanks
