Fitment comparison
265/35 R22versus315/30 R22
Δ Ø +3.5 mmSpeedo +0.47%OEM-safe
315/30 R22 stands taller than 265/35 R22 — bigger rolling diameter, slightly more clearance, calmer cruise revs.
Stepping from 265/35 R22 to 315/30 R22 keeps the 22-inch wheel but widens the section by 50 mm. This alternative fitment barely shifts the rolling circumference.
Speedometer error is effectively zero, so ABS and traction control read the road as they did from the factory. Expect a more planted steering feel, at the cost of some of the cushioning a taller sidewall provides. Extra width broadens the footprint for more grip, but check inner liner and strut clearance before fitting. 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.

Fender Clearance
Likely rubs
Significantly wider/taller — rubbing risk on liners or fender lip is real.
Speedometer Impact
+0.47%
At a true 100 km/h the dash reads 100.5 km/h — negligible.
Daily Driving
Livable
Daily use is fine; expect a slightly different ride and cruise rev count.

How this setup changes the car
Driver-perspective read-out of the 265/35 R22 → 315/30 R22 swap — steering, comfort, stance and dash behavior in plain enthusiast language.
Steering feel
+1.8 mm sidewallSteering response stays familiar
Sidewall delta is small; the wheel will feel like the OEM setup at the rim.
Ride firmness

Wider tire pushes the contact patch outboard — flusher stance, but verify fender lip clearance at full lock.
Speedometer behavior
+0.47%OEM-safe speedometer reading
Inside the factory ±3% tolerance — ABS, ESP and cruise control behave as designed.
Daily drivability

Direct answer
Is 315/30 R22 OEM-safe?
Yes. Overall diameter changes by +0.47% versus 265/35 R22. OEM-safe. Speedometer, ABS, ESP and gearing remain inside the factory tolerance.
Direct answer
Will 315/30 R22 rub?
Possibly. Width changes by +50 mm and diameter by +3.5 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 +0.47%. Swapping 265/35 R22 for 315/30 R22 changes overall diameter, so at an indicated 100 km/h your true speed becomes 100.5 km/h. That's within the ±3% OEM tolerance — no recalibration needed.
Direct answer
Does lower sidewall affect comfort?
Barely. Sidewall changes by +1.8 mm (35% → 30%). Comfort is essentially unchanged.

Real-world consequences
Pros / consWider tire (+50 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

Lower profile (-5% aspect)
Sidewall- Sharper turn-in and less sidewall roll
- More planted on smooth tarmac
- Bigger brake / caliper visual real estate
- Harsher ride over expansion joints and potholes
- Higher wheel-damage risk on impacts
- Less curb protection for the rim lip
- More sensitive to correct tire pressure

Cluster preview
Within toleranceSpeedometer impact
At a true 100 km/h, your dashboard will read 100.5 km/h after switching to 315/30 R22 — a +0.47% 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 +1.8 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.
