Beyond OEM tolerance — speedometer and ABS need professional review.
Fitment comparison
155/70 R13versus175/70 R13
Δ Ø +28.0 mmSpeedo +5.12%Aggressive
175/70 R13 stands taller than 155/70 R13 — bigger rolling diameter, slightly more clearance, calmer cruise revs.
On the same 13-inch wheel, 175/70 R13 grows the section width by 20 mm versus 155/70 R13. This tire combination noticeably changes overall diameter compared to OEM.
The dashboard speed will be significantly off — plan on recalibration before daily use. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. A diameter change beyond 5% is aggressive enough to influence ABS, traction control and gearing; treat it as a serious modification.
TakeTreat as a serious modification — verify clearance, recalibrate the speedometer and reassess load capacity.

How this setup changes the car
Driver-perspective read-out of the 155/70 R13 → 175/70 R13 swap — steering, comfort, stance and dash behavior in plain enthusiast language.
Steering feel
+14.0 mm sidewallSofter, more relaxed turn-in
Taller sidewall flexes a touch more before loading the contact patch — calmer, comfort-tuned.
Ride firmness
70% → 70%Softer over potholes and joints
Bumps and expansion joints are absorbed better — a comfort win for daily driving.
Fender relationship
+20 mm widthWheel sits closer to the fender
Wider tire pushes the contact patch outboard — flusher stance, but verify fender lip clearance at full lock.
Speedometer behavior

Beyond ±5% — speedometer, gearing and ABS calibration all need a professional review.
Daily drivability

Direct answer
Is 175/70 R13 OEM-safe?
No. Overall diameter changes by +5.12% versus 155/70 R13. Not OEM-safe. Overall diameter strays beyond ±5% — recalibration and clearance review are required.
Direct answer
Will 175/70 R13 rub?
Possibly. Width changes by +20 mm and diameter by +28.0 mm. Possible rub at full lock or full suspension compression — verify fender lip and inner strut clearance before committing.
Direct answer
Does the speedometer change?
Yes — by +5.12%. Swapping 155/70 R13 for 175/70 R13 changes overall diameter, so at an indicated 100 km/h your true speed becomes 105.1 km/h. That's outside safe tolerance — recalibrate.
Direct answer
Does lower sidewall affect comfort?
Yes — softer ride. Sidewall changes by +14.0 mm (70% → 70%). Ride softens and absorbs bumps better, with slightly less precise turn-in.

Real-world consequences
Pros / consWider tire (+20 mm)
Section width- More dry grip and cornering bite
- Sharper steering response on initial turn-in
- Bigger contact patch under braking
- More road noise on coarse asphalt
- Worse aquaplaning resistance in standing water
- Higher rolling resistance, small MPG hit
- Possible fender or strut contact at full lock
Taller overall (+28.0 mm)
Rolling diameter- Higher ground clearance and approach angle
- Longer effective gearing — calmer highway revs
- Bigger contact patch lengthwise
- Speedometer reads low by ~5.1%
- Reduced fender, strut and bumpstop clearance
- Slower 0-60, more downshifts under load

Cluster preview
Excessive driftSpeedometer impact
At a true 100 km/h, your dashboard will read 105.1 km/h after switching to 175/70 R13 — a +5.12% 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 +14.0 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.
