Comparison
205/65 R15 vs 215/65 R15
On the same 15-inch wheel, 215/65 R15 grows the section width by 10 mm versus 205/65 R15. This tire combination shifts overall diameter slightly from OEM. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance.
The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. 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: 215/65 R15 is 13.0 mm taller than 205/65 R15, shifting the speedometer by +2.01%.

Speedometer impact
At a true 100 km/h, your dashboard will read 102.0 km/h after switching to 215/65 R15 — a +2.01% 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 +6.5 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.
