225/40 R19 vs 235/35 R19
On the same 19-inch wheel, 235/35 R19 grows the section width by 10 mm versus 225/40 R19. This alternative fitment moves rolling diameter a touch off the original spec.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeReasonable performance-leaning swap as long as fender and suspension clearance check out.
Quick math: 235/35 R19 is 15.5 mm shorter than 225/40 R19, shifting the speedometer by -2.34%.
