Comparison
265/35 R22 vs 275/40 R22
Stepping from 265/35 R22 to 275/40 R22 keeps the 22-inch wheel but widens the section by 10 mm. This wheel and tire pairing moves rolling diameter well outside the usual OEM tolerance. Extra sidewall absorbs impacts more readily — a sensible bias for daily commuting and broken pavement.
Indicated speed will drift far enough that recalibration is worth considering. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakeReasonable performance-leaning swap as long as fender and suspension clearance check out.
Quick math: 275/40 R22 is 34.5 mm taller than 265/35 R22, shifting the speedometer by +4.64%.

Speedometer impact
At a true 100 km/h, your dashboard will read 104.6 km/h after switching to 275/40 R22 — a +4.64% 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 +17.3 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.
