Stock tire size?
Is there any way to figure out what tire size my truck came with stock?
I'm trying to judge correct speed/miles driven, etc. My truck currently has 31" tires on it, (31x10.5r15). I assume that the odometer is off a ring gear in the transmission like it is in my jeep, and not software defined like it is on newer vehicles.
When I go online it looks like there were 3 tire size options, 215/235/265 75r15.
That's a pretty big difference between the three sizes, and I assume the ring gear is based off the original size.
