Fitment Guide
The overall diameter of 235/65r17 tires is 1.8% larger than 225/65r17 tires. So 235/65r17 can directly replace 225/65r17 without the need for lifting or levelling kits to prevent rubbing at complete turn.
Gas Mileage
The slightly narrower 225/65r17 tires have a smaller contact patch and lower rolling resistance than 235/65r17, making them more fuel-efficient.
Over time, the modest improvement in MPG with the 225/65r17 can add up to measurable fuel savings.
Ground Clearance
With a 1.8% larger diameter, the 235/65r17 tire size provides 0.26 inch (6.5mm) more ground clearance than the 225/65r17 size.
This added clearance is useful for light off-roading, clearing obstacles, and preventing bottom scrapes.
However, the larger 235/65r17 diameter causes a slightly lower speedometer reading by 1.8% compared to the 225/65r17 at any given actual speed.
Ride Comfort
The taller sidewall of 235/65r17 tires flexes more to absorb impacts, potentially providing a smoother ride over uneven surfaces than 225/65r17 tires. However, both offer comfortable on-road performance.
Speedometer Difference
At an actual vehicle speed of 20 mph, the speedometer reads 20.36 mph with 235/65r17 tires equipped versus 20 mph with 225/65r17 tires.
This 0.36 mph difference is due to the 1.8% larger diameter of the 235/65r17 tire.
Aesthetics
The visual difference between 225/65r17 and 235/65r17 tires is subtle. The 235/65r17 will have a slightly taller sidewall, giving a modestly “stretched” look compared to the 225/65r17. This fits some vehicle aesthetics better than an ultra-low-profile appearance.
Handling & Stability
The shorter sidewall and narrower tread of the 225/65r17 tire provide crisper steering response and handling precision compared to the 235/65r17. However, both deliver responsive, stable handling for normal driving conditions.
Noise & Vibration
With a shorter and stiffer sidewall, the 225/65r17 transmits more road noise and vibration into the cabin versus the 235/65r17.
The extra cushioning from the taller 235/65r17 sidewall helps dampen noise and vibration for a slightly smoother, quieter ride.
Durability & Wear
The narrower 225/65r17 tire exhibits slightly more even treadwear across its width versus the wider 235/65r17 tire. Its more minor contact patch can marginally improve tread life over time.
But both tire sizes deliver good durability and wear when properly maintained.
Adverse Conditions
The narrower 225/65r17 tire cuts through to the pavement more effectively thanks to its smaller footprint and tread blocks than the wider 235/65r17 tire for snow and ice traction.
However, the wider 235/65r17 performs better in muddy or loose soil conditions.
