What changes between 235/60R20 and 295/50R20
Switching from 235/60R20 to 295/50R20 changes overall diameter by +1.65%, a taller tire by 0.51 inches. This lands inside the ±3% fitment safe zone, so most vehicles will accept the swap without rubbing, speedometer recalibration, or ABS/TPMS complications. Section width moves by +2.36″ (235mm → 295mm), which affects contact patch and fender-well clearance. Sidewall height shifts by +0.26″: a taller sidewall softens ride quality and adds off-road bump protection, with some loss of steering crispness. Revs per mile moves by -10, which translates directly to speedometer error — at an indicated 65 mph, actual speed becomes 66.1 mph. Both sizes share the same 20″ rim, so no wheel change is required — this is a pure tire-only swap.
