Difference between stock tire sizes.
My '94 came originally with 225/75-15 tires, I know that 31x10.5-15s where an option. Was there any difference in gearing between these two tire options or was just a different speedometer calibration? Thanks!

I took a look at the place card. It reads G254 on the axle code. According to this site, that means 8" with 4.556 gears. It also shows that being the ratio for the 31" option tires. Now I'm even more confused...

Which means that whoever has put new tires on it over the years just put on OEM standard. They usually ask (because it is an option), or you have to request it.

Alright, thanks man! Hopefully this winter I can sell my other truck (Ford Ranger) and get something going on the 4Runner (engine, lift, tires, etc.)...

the vin tag on the inside of the door jamb also states the stock tire size... mine said 225/75 r15 which is equals roughly 28" tires. so i have 4.30s
its to the right of the GAWR and has front tire size above the rear tire size, which are obviously the same lol.

axle code isn't 100% either, the only way to truly tell is to jack a wheel up and spin it 720 degrees (open diff) and count the number of driveshaft revolutions
