265/70R16 vs 265/75R16: What Changes
Common on first-gen Tacomas and 16-inch half-tons, this pairing keeps the same 265 tread width but swaps a 70-series sidewall for a taller 75-series. The result is a bit more diameter and clearance with no change in width, an easy way to gain height without worrying about extra rubbing on the outer fender.
Frequently Asked Questions
How much taller is 265/75R16 than 265/70R16?
About an inch of overall diameter, from the taller 75-series sidewall. That adds roughly half an inch of ground clearance.
Will keeping the same width make 265/75R16 an easy fit?
Usually. Because only the height changes, outer-fender clearance is unaffected; the main thing to watch is diameter clearance at full compression.
