235/35 R19 vs 265/35 R19
265/35 R19 is a wider variation of 235/35 R19 on the same 19-inch rim, adding 30 mm of tread footprint. This tire combination noticeably changes overall diameter compared to OEM. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance.
Indicated speed will drift far enough that recalibration is worth considering. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeUseful when extra dry grip and stance matter more than a small fuel-economy hit.
Quick math: 265/35 R19 is 21.0 mm taller than 235/35 R19, shifting the speedometer by +3.25%.
