OEM Safe
Borderline
Noticeable drift from OEM — drivable, but recalibration is wise.

Δ Ø +20.3 mmSpeedo +3.53%Borderline
195/55 R15 stands taller than 175/70 R13 — bigger rolling diameter, slightly more clearance, calmer cruise revs.
195/55 R15 is a plus-2 alternative to 175/70 R13 — the bigger wheel shows through a thinner sidewall. This alternative fitment swings rolling diameter far enough to feel on the road. Less sidewall flex usually translates to crisper turn-in and a slightly stiffer ride over rough pavement.
The speedometer error is noticeable and may warrant a recalibration if you rely on indicated speed. Diameter delta falls in the cautious 3–5% range, where speedometer recalibration and a careful clearance check are worth doing.
TakeA solid pick for drivers chasing a more aggressive stance without abandoning OEM rolling diameter.

How this setup changes the car
Driver-perspective read-out of the 175/70 R13 → 195/55 R15 swap — steering, comfort, stance and dash behavior in plain enthusiast language.
Steering feel
-15.3 mm sidewallSharper steering response
Shorter sidewall transmits inputs faster — quicker turn-in, more confident on-center feel.
Ride firmness

Expect more chatter on broken tarmac and a sharper pothole strike — keep an eye on wheel damage risk.
Fender relationship

Wider tire pushes the contact patch outboard — flusher stance, but verify fender lip clearance at full lock.
Speedometer behavior

Direct answer
Is 195/55 R15 OEM-safe?
Borderline. Overall diameter changes by +3.53% versus 175/70 R13. Borderline. Drivable, but speedometer drift becomes noticeable and ABS calibration is affected.
Direct answer
Will 195/55 R15 rub?
Possibly. Width changes by +20 mm and diameter by +20.3 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 +3.53%. Swapping 175/70 R13 for 195/55 R15 changes overall diameter, so at an indicated 100 km/h your true speed becomes 103.5 km/h. That's noticeable drift but usually safe.
Direct answer
Does lower sidewall affect comfort?
Yes — firmer ride. Sidewall changes by -15.3 mm (70% → 55%). Ride becomes firmer and steering sharper, but potholes and expansion joints hit harder and wheel damage risk rises.

Cluster preview
BorderlineSpeedometer impact
At a true 100 km/h, your dashboard will read 103.5 km/h after switching to 195/55 R15 — a +3.53% 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 +10.1 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.
