Is 175/70 R13 a safe replacement for 165/70 R13?

Within ±3% diameter — generally considered a safe replacement from a speedometer-error standpoint, provided wheel offset, rim width and clearance also match your vehicle.

What else should I check before changing tire size?

Beyond diameter and speedometer error, verify wheel offset (ET), rim width, hub bore, load index, brake and suspension clearance, and your vehicle's manufacturer specification. Local regulations may also limit how far you can deviate from OEM.

Fitment comparison

165/70 R13versus175/70 R13

Δ Ø +14.0 mmSpeedo +2.49%OEM-safe

175/70 R13 stands taller than 165/70 R13 — bigger rolling diameter, slightly more clearance, calmer cruise revs.

Stepping from 165/70 R13 to 175/70 R13 keeps the 13-inch wheel but widens the section by 10 mm. This alternative fitment trims or stretches rolling diameter by a small margin. The speedometer offset is small but measurable; worth keeping in mind if you watch the dash closely. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance. Overall the swap sits inside the safe ±3% diameter window, so ABS, traction control and gearing behave normally.

TakeReasonable performance-leaning swap as long as fender and suspension clearance check out.

Direct answer

Is 175/70 R13 OEM-safe?

Yes. Overall diameter changes by +2.49% versus 165/70 R13. OEM-safe. Speedometer, ABS, ESP and gearing remain inside the factory tolerance.

Direct answer

Will 175/70 R13 rub?

Borderline. Width changes by +10 mm and diameter by +14.0 mm. Borderline — check fender lip and inner strut clearance under load.

Direct answer

Does the speedometer change?

Yes — by +2.49%. Swapping 165/70 R13 for 175/70 R13 changes overall diameter, so at an indicated 100 km/h your true speed becomes 102.5 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 +7.0 mm (70% → 70%). Ride softens and absorbs bumps better, with slightly less precise turn-in.
