Comparison
245/45 R17 vs 265/35 R19
Plus-sizing from 245/45 R17 to 265/35 R19 keeps overall diameter close to factory while opening room for a larger 19-inch wheel. This tire combination trims or stretches rolling diameter by a small margin. Less sidewall flex usually translates to crisper turn-in and a slightly stiffer ride over rough pavement.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeCommon upgrade for sportier handling and a tighter wheel-gap look on the same vehicle.
Quick math: 265/35 R19 is 15.8 mm taller than 245/45 R17, shifting the speedometer by +2.42%.
