Just ordered 1 1/4 axle kit, mcp break kit and a couple other parts. I can't use 16/7.5/8 tires because it will increase my ride height .I want to use 7-8" wide rims. I don't want to chance my 15/6.5/8 turf masters on 8 -8" rims. I'm wondering if BMi,s Douglas 7-8" rims have any bead lock on them like the ec ones.??????hold the tire on good? I run tubes but 5psi left-10-15 psi right.I'm new to all this cart stuff. I'm having a hard time finding them on Itp . I got the tires on factory 7-8 and the 15 seems to be the lowest I can drop the rear end.any help would be appreciated.
