Fitment comparison
225/35 R19versus245/35 R19
Δ Ø +14.0 mmSpeedo +2.19%OEM-safe
245/35 R19 stands taller than 225/35 R19 — bigger rolling diameter, slightly more clearance, calmer cruise revs.
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.

Driver-perspective read-out of the 225/35 R19 → 245/35 R19 swap — steering, comfort, stance and dash behavior in plain enthusiast language.
Steering feel
+7.0 mm sidewallSofter, more relaxed turn-in
Taller sidewall flexes a touch more before loading the contact patch — calmer, comfort-tuned.
Ride firmness

Direct answer
Is 245/35 R19 OEM-safe?
Yes. Overall diameter changes by +2.19% versus 225/35 R19. OEM-safe. Speedometer, ABS, ESP and gearing remain inside the factory tolerance.
Direct answer
Will 245/35 R19 rub?
Borderline. Width changes by +20 mm and diameter by +14.0 mm. Borderline — check fender lip and inner strut clearance under load.
Direct answer
Does the speedometer change?
Yes — by +2.19%. Swapping 225/35 R19 for 245/35 R19 changes overall diameter, so at an indicated 100 km/h your true speed becomes 102.2 km/h. That's within the ±3% OEM tolerance — no recalibration needed.
Direct answer
Does lower sidewall affect comfort?
Yes — softer ride. Sidewall changes by +7.0 mm (35% → 35%). Ride softens and absorbs bumps better, with slightly less precise turn-in.

Cluster preview
Within toleranceSpeedometer impact
At a true 100 km/h, your dashboard will read 102.2 km/h after switching to 245/35 R19 — a +2.19% offset. Use the speedometer error calculator for any indicated speed, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by +7.0 mm. Small differences are absorbed by suspension travel, but anything beyond ±10 mm can affect headlight aim, fender clearance and bump-stop margin. See the plus-sizing guide before committing.
