Fitment comparison
165/65 R14versus155/80 R13
Δ Ø +8.1 mmSpeedo +1.42%OEM-safe
155/80 R13 stands taller than 165/65 R14 — bigger rolling diameter, slightly more clearance, calmer cruise revs.
155/80 R13 drops the rim from 14 to 13 inches versus 165/65 R14, trading wheel size for taller sidewall. This sizing approach keeps overall diameter very close to stock. Extra sidewall absorbs impacts more readily — a sensible bias for daily commuting and broken pavement.
The speedometer offset is mild and well inside what most cars can tolerate without recalibration. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakeTypical choice for a dedicated winter or off-road setup where extra sidewall pays off.

Direct answer
Is 155/80 R13 OEM-safe?
Yes. Overall diameter changes by +1.42% versus 165/65 R14. OEM-safe. Speedometer, ABS, ESP and gearing remain inside the factory tolerance.
Direct answer
Will 155/80 R13 rub?
Unlikely. Width changes by -10 mm and diameter by +8.1 mm. Very unlikely to rub with OEM wheel offset.
Direct answer
Does the speedometer change?
Yes — by +1.42%. Swapping 165/65 R14 for 155/80 R13 changes overall diameter, so at an indicated 100 km/h your true speed becomes 101.4 km/h. That's within the ±3% OEM tolerance — no recalibration needed.
Direct answer
Does lower sidewall affect comfort?
Yes — softer ride. Sidewall changes by +16.8 mm (65% → 80%). Ride softens and absorbs bumps better, with slightly less precise turn-in.

- 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

- More sidewall flex, softer steering feel
- Slightly delayed turn-in response
-1″ rim downsize
Wheel diameter- Cheaper winter / track tire sizing

Cluster preview
Within toleranceSpeedometer impact
At a true 100 km/h, your dashboard will read 101.4 km/h after switching to 155/80 R13 — a +1.42% 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 +4.1 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.
