I picked up another big bolt, a 57 GMC F350 LCF. The front rims are 9.00x22.5 and the rear rims are 9.00x20 but it came with 3 matching 22.5 for the back. I'd like to go all tubeless but haven't had any luck tracking down the one rim. Have tried a couple junkyards but anytime I find a 6 lug budd 22.5 it's much wider. The 3 wheels I have now are 7.5" outer lip to outer lip so I assume 6.75 wide rims, I'll verify tomorrow. I'm in Phoenix, what would be the best places to try and find a rim? Also is anyone running 10.00X22.5 mud tires and if so what brand?
