175/70 R13versus165/70 R14
Δ Ø +11.4 mmSpeedo +1.98%OEM-safe
165/70 R14 stands taller than 175/70 R13 — bigger rolling diameter, slightly more clearance, calmer cruise revs.
Switching from 175/70 R13 to 165/70 R14 is a plus-1 upgrade that wraps a shorter sidewall around a larger 14-inch wheel. This sizing approach shifts overall diameter slightly from OEM. The narrower section trims rolling resistance and tends to cut through snow more effectively.
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.
TakeCommon upgrade for sportier handling and a tighter wheel-gap look on the same vehicle.

Direct answer
Is 165/70 R14 OEM-safe?
Yes. Overall diameter changes by +1.98% versus 175/70 R13. OEM-safe. Speedometer, ABS, ESP and gearing remain inside the factory tolerance.
Direct answer
Will 165/70 R14 rub?
Borderline. Width changes by -10 mm and diameter by +11.4 mm. Borderline — check fender lip and inner strut clearance under load.
Direct answer
Does the speedometer change?
Yes — by +1.98%. Swapping 175/70 R13 for 165/70 R14 changes overall diameter, so at an indicated 100 km/h your true speed becomes 102.0 km/h. That's within the ±3% OEM tolerance — no recalibration needed.
Direct answer
Does lower sidewall affect comfort?
Yes — firmer ride. Sidewall changes by -7.0 mm (70% → 70%). Ride becomes firmer and steering sharper, but potholes and expansion joints hit harder and wheel damage risk rises.

Real-world consequences
Pros / consNarrower tire (-10 mm)
Section width- Better aquaplaning resistance
- Lower rolling resistance and slightly better MPG
- Quieter ride, less tramlining
- Lighter unsprung mass on the corner
- Less dry grip at the limit
- Smaller contact patch under hard braking
- Stance can look tucked or undersized
Taller overall (+11.4 mm)
Rolling diameter- Higher ground clearance and approach angle
- Longer effective gearing — calmer highway revs
- Bigger contact patch lengthwise
- Speedometer reads low by ~2.0%
- Reduced fender, strut and bumpstop clearance
- Slower 0-60, more downshifts under load
+1″ rim upsize
Wheel diameter- OEM+ look, fills the arch better
- Sharper response with matching low-profile rubber
- Bigger brake clearance for upgrades
- Heavier wheel, more unsprung mass
- Harsher ride, more wheel-damage risk
- Tire and wheel cost both go up

Within toleranceSpeedometer impact
At a true 100 km/h, your dashboard will read 102.0 km/h after switching to 165/70 R14 — a +1.98% offset. Use the speedometer error calculator for any indicated speed, 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.
