225/60 R17 vs 235/65 R17
On the same 17-inch wheel, 235/65 R17 grows the section width by 10 mm versus 225/60 R17. This swap noticeably changes overall diameter compared to OEM. The dashboard speed will be significantly off — plan on recalibration before daily use. More sidewall typically improves comfort and curb protection, especially on city streets. The diameter gap exceeds 5%, which can affect speedometer accuracy, ABS calibration and final gearing — review with a professional first.
TakeRecommended only after a professional fitment check and speedometer recalibration.
Quick math: 235/65 R17 is 35.5 mm taller than 225/60 R17, shifting the speedometer by +5.06%.

Speedometer impact
At a true 100 km/h, your dashboard will read 105.1 km/h after switching to 235/65 R17 — a +5.06% offset. Use the speedometer error calculator to recheck for other indicated speeds, and the speedometer error guide for the full background.
Ground clearance change
The new tire's half-diameter changes ride height by +17.8 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.
