235/75R15 are the larger size offered on the s-series (non-ZR2) trucks. They will fit no problem, however, your speedometer and odometer will be reading incorrectly unless you have the PCM tuned to the new tire diameter.

My truck came with 235 70 15 and I stuck on 235 75 15 and the speedometer is right on the dot. Maybe the old tires made the speedometer run fast, or maybe there are higher powers at work.
