It is NEVER correct by factory..going smaller is quite strange to ask. |
Smaller = less rotating mass to accelerate, but the 4.80/12's are actually pretty close to the same size as 155R13's. You can change gearing on a OEM vehicle to account for tire size changes.
Once again, I was figuring on using something like this on a small vehicle, like an NEV or something similar.
