Summit 6 lug vision wheels and tire size

[SwitchbladeII]

When I built my 36 Chevy street rod I wanted the biggest tire that I could fit in the rear. I ended up building a fixture out of wood and cardboard. You can buy a fancy one but for a one shot deal it was not worth it to me. I got the specs on different tires, section width, tread width and diameter. I then set my high tech tool and rotated in the wheel well. I cut the card board to match the profiles and secured the wood arm to the drum to set diameter. A few things to mind in mind is to check inside due to fact that body lean in a corner will bring tire closer than in a static position also weight in the bed, hitting bump, pothole or while steering wheel is max left or right. With all that said there is more clearance on truck than in most cars.
