Comparison
225/40 R19 vs 275/35 R19
On the same 19-inch wheel, 275/35 R19 grows the section width by 50 mm versus 225/40 R19. This tire combination shifts overall diameter slightly from OEM. 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.
TakeUseful when extra dry grip and stance matter more than a small fuel-economy hit.
Quick math: 275/35 R19 is 12.5 mm taller than 225/40 R19, shifting the speedometer by +1.89%.
