Tire Size 215/55r17 vs 225/55r17


The main difference between tire sizes 215/55R17 and 225/55R17 lies in their width. The 225/55R17 tire is wider by 0.39 inches (10mm), providing a potentially increased contact patch with the road. This could enhance grip, stability, and braking performance.

225/55r17 vs 215/55r17

This comparison table will help you understand the differences between the two sizes.

Fitment Guide

The 225/55r17 width is 1.6% broader than the 215/55r17. This minor size difference falls well within the 3% limit for direct replacement without modifications.

Both widths should properly fit the same vehicles without clearance or fitment problems. Owners can safely transition between these sizes if needed.

Gas Mileage

The narrower 215/55r17 tire has a smaller contact patch, which reduces rolling resistance compared to the 225/55r17.

This can translate into slightly better fuel efficiency, making the 215 widths advantageous for commuters focused on eking out every mile per gallon.

Ground Clearance

With identical diameters, ground clearance is unaffected going between these sizes. Ride height remains identical. Vehicle owners need not modify or lift their suspension to achieve adequate clearance.

Ride Comfort

The 225/55r17’s wider tread face cushions impacts slightly better. But both widths utilize the same 55 aspect ratio sidewall, so differences are subtle. Either width provides comfortable ride quality for a low-profile 17” tire.

Speedometer Difference

Despite having little difference in overall diameter, the 225’s higher revolutions per mile cause a 0.33 mph increase in speedometer reading when travelling at an actual 20 mph. This negligible difference has essentially no impact on real-world driving.


Visually differentiating the two widths is difficult unless viewed side-by-side. The 225 appears subtly broader whereas the 215 seems just a touch more stretched. Subjectively, the wider 225 suits sportier coupes better while the 215 has a classier look.

Handling & Stability

The 215’s narrower tread face provides sharper turn-in response and handling precision. But the more expansive 225 offers incrementally better cornering grip and stability at the limit. For most drivers, any handling differences are imperceptible. Both deliver responsive, agile handling.

Noise & Vibration

Identical diameters and aspect ratios mean noise and vibration levels are nearly equal. Both transmit some road impacts through their short sidewalls.

The 225 dampens roughness slightly better courtesy of its broader tread face. Overall NVH levels are low for both.

Durability & Wear

With more rubber meeting the road, the 225 wears slightly faster on the outer shoulders. But tread life difference is negligible at best. Owners can expect comparable durability and longevity from either width.

Adverse Conditions

Performance in rain, snow and light off-roading is comparable. The narrower 215 cuts through powder and slush efficiently.

Yet the 225’s extra width enhances snow and mud traction. Both widths work well across varying conditions.

How Much Taller Is A 225 Tire Than A 215?
