67 chevy stock size tire drop? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

looking for photos of 67 or 68 chevys with stock 235/75/15 size tires on them that are dropped. triing to figure out what drop to go with. from measuring mine i think i can go 4/6, but not sure if the front will clear the fender. already have 2.5 drop spindles on my new frame. but need to get some springs. post what drop you have with it please to help out. thanks!

any pics with stock size(or the same diam-different size rims) with 4.5/6 drop or 3.5/5 just curious if they will clear the fenders or not.

I have 235/75/15 on bags, but this is probably no help.

any chance you know the measurements to the fender lip from the ground how it sits? awesome truck btw. eventually i want to go air, but this is a fix as i go truck. still want to drive it.

Not exactly what you are looking for, but close. Those should be 235/75/15's. The drop is a 2.5" spindle + 1" springs in the front. Back is bags with a target of 5.5" drop. In this picture the rear might not be set for 5.5 - maybe closer to 6"?

I'm not thinking that a 235-75 is the correct equivalent for the OEM 7.75x15 that would have been on the majority of these 1/2-ton trucks. The upgrade tire size would be an 8.00 or 8.15. Of course, those were bias-ply tires and that was what we had. Here's a link to a chart that tells about converting from bias ply to radial. It starts with letter sizes...like A78, for example. I know that G-78-15 was a tire size on the later models...and that converts to a 215-75R15.
