I've got 16X8 Wheel Vintique Chrome Chevy Rallies with
LT 245 x 75R 16 Michelin Truck Radials on my 51 half ton panel
All the way around.
The back was lowered a couple of inches but still clears the wheel wells
(56 Olds Rear end)
The front is stock suspension but power discs, power steering, and GIANT
stabilizer bar (CPP)
No clearance issues, but certainly fills up the space under there!
