Comparison
155/80 R13 vs 195/55 R15
Switching from 155/80 R13 to 195/55 R15 is a plus-2 upgrade that wraps a shorter sidewall around a larger 15-inch wheel. This tire combination shifts overall diameter slightly from OEM. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides.
Expect a slight but noticeable shift in indicated speed compared to the original tires. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.
Quick math: 195/55 R15 is 17.3 mm taller than 155/80 R13, shifting the speedometer by +2.99%.

At a true 100 km/h, your dashboard will read 103.0 km/h after switching to 195/55 R15 — a +2.99% 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 +8.6 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.
