Need feedback on wheel and tire combo - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My Dad and I are building a 67 step side. It has 2 1/2" drop spindles with disc on the front and a 4 link 9 inch disc brake in the back. The rear is 55" WSM - WSM. We plan to run Coy C5 20x10 (5x4.5) with 3.5" BS mounted to 295/45R20. The fronts will be 20x8.5 (5x5) with 5.25" BS mounted to 255/40R20. The best we can measure is 73.5"from fender lip to lip. Your feedback will be most welcomed to advise us of any interference or better recommendations.

Just out of curiosity, why are you running 5" bolt circle front & 4 1/2" bolt circle rear? Typo?

Use this to be accurate in your measurements.

I assume you have mini-tubbed the bedsides?
I like a 295/40-20 better.
Those stepside fenders are really tiny.

Your rear wheels will have 7.5" on the front side of each wheel.
(7.5" x 2 = 15" total)
Rearend 55" + 15" = 70" total width

73.5 - 70 =3.5" total
3.5" divided by 2 = 1.75" clearance to the fender lip.

You may have to run a 1" spacer to bring the wheels out a little.
Just my opinion on your numbers,...

Suspect - we have a 9 inch that has a 5x4.5 bolt pattern.

Thank you for the feed back. Does anyone have pics with coy wheels on their rides with tire sizes and drops?
