Comparison
165/70 R14 vs 175/70 R13
Switching from 165/70 R14 to 175/70 R13 steps down to a 13-inch wheel — a familiar move for winter and dedicated all-terrain sets. This wheel and tire pairing shifts overall diameter slightly from OEM. The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. More tread on the ground tends to improve dry grip and stance, with a small fuel-economy and clearance tradeoff. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.
TakePractical direction for winter wheels, chains, or rougher pavement where cushioning matters.
Quick math: 175/70 R13 is 11.4 mm shorter than 165/70 R14, shifting the speedometer by -1.94%.

Speedometer impact
At a true 100 km/h, your dashboard will read 98.1 km/h after switching to 175/70 R13 — a -1.94% 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 -5.7 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.
