What changes between 275/45R22 and 295/45R22
Switching from 275/45R22 to 295/45R22 changes overall diameter by +2.23%, a taller tire by 0.71 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 +0.78″ (275mm → 295mm), which affects contact patch and fender-well clearance. Sidewall height shifts by +0.36″: a taller sidewall softens ride quality and adds off-road bump protection, with some loss of steering crispness. Revs per mile moves by -14, which translates directly to speedometer error — at an indicated 65 mph, actual speed becomes 66.5 mph. Both sizes share the same 22″ rim, so no wheel change is required — this is a pure tire-only swap.
