Comparison
225/35 R19 vs 245/35 R19
245/35 R19 is a wider variation of 225/35 R19 on the same 19-inch rim, adding 20 mm of tread footprint. This tire combination 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. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. 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: 245/35 R19 is 14.0 mm taller than 225/35 R19, shifting the speedometer by +2.19%.
