I'm trying to figure out what the factory tire size for a 1977 Dodge D100 pickup is.
I'd also like to know what the OE rim width is.
Right now, the truck is sitting on a mix of G78-15 and H78-15 tires. Not sure which, if either, is the correct size.
Different tire websites give me different results for modern conversions. (205/75R15, 235/75R15, 225/70R15... )
This truck is a pretty low-end light-duty example. 225 slant six engine, 3-speed manual on the column, 2WD. VIN indicates GVWR "under 6000 lbs", but the data tag on the truck says GVW is 6100 lbs (???).
The truck doesn't run and is sitting on flat tires. I need to get it roll-able so it can be loaded onto a trailer. The quickest way to do that might be to put the wheels from my 1999 Ford Ranger on it. Same bolt pattern and stud size. However, the center hole on the Ranger wheels is 1.1mm smaller than the Dodge wheels, according to wheel-size.com. The center hole of the Ranger wheels fit fairly snug around the Ranger hub. I'm not sure if the Dodge wheel's center hole fits tightly around the dodge hub, or if there is a bit of a gap. If there's a gap, the Ranger wheels might fit the Dodge.
Does anyone know if there's clearance between the hub and the center hole in the wheel on these old half-ton dodges?
The truck resides about an hour away from me, so I'm trying to figure this stuff out in advance so I don't have to make a trip just to take measurements, or waste a bunch of time removing the wheels from my Ranger and hauling them out there only to find they won't fit.
Thanks!
