Comparison
195/65 R15 vs 215/65 R15
On the same 15-inch wheel, 215/65 R15 grows the section width by 20 mm versus 195/65 R15. This wheel and tire pairing moves rolling diameter well outside the usual OEM tolerance. Indicated speed will drift far enough that recalibration is worth considering. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance. The 3–5% diameter gap puts this in caution territory: doable on many cars, but verify clearance and consider recalibration.
TakeUseful when extra dry grip and stance matter more than a small fuel-economy hit.
Quick math: 215/65 R15 is 26.0 mm taller than 195/65 R15, shifting the speedometer by +4.10%.

Speedometer impact
At a true 100 km/h, your dashboard will read 104.1 km/h after switching to 215/65 R15 — a +4.10% 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 +13.0 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.
