can I run 255/75r17 tires instead of 265/70r17
Yes as long as you replace all 4, they just won't be as wide.
what john said plus the diameter of the wheel will be slightly bigger and will affect the speedometer.. basically u will be traveling faster than what the speedo says..
Great calculator for this here: https://www.tacomaworld.com/tirecalc?tires=265-70r16-265-70r17
