Fitment Guide
The overall diameter of 235/45R17 tires is only 1.4% larger than 225/45R17 tires. This is well within the 3% limit for direct replacement without any modifications.
So 235/45R17 can directly replace 225/45R17 tires without any clearance issues or need for lifting kits.
Gas Mileage
The 225/45R17 tires offer marginally better fuel efficiency with a slightly smaller contact patch than the 235/45R17.
The wider 235 tires have more rolling resistance, resulting in reduced mpg. However, the difference is minor – only about one mpg.
Ground Clearance
The diameter of 235/45R17 tires is 0.35 inches larger, providing slightly more ground clearance.
This can help prevent scrapes and damage when driving over obstacles or rough terrain. However, the difference is small at just over 1/3rd of an inch.
Ride Comfort
With almost identical diameters, both 225/45R17 and 235/45R17 provide nearly equal ride quality and comfort over smooth roads.
However, the wider 235 may absorb more road impacts, providing a slightly smoother ride over uneven surfaces. But any differences would be modest at most.
Aesthetics
Visually, the wider 235 tires fill out the wheel wells more than the narrower 225 tires, providing a more muscular, aggressive look.
For some vehicles, this wider stance enhances the overall styling. However, aesthetics are subjective to personal taste.
Handling & Stability
The 225/45R17, with its smaller contact patch, offers quicker steering response and sharper handling.
The wider 235 tires trade off some responsiveness for more stability and traction. However, both deliver responsive and stable handling for normal driving conditions.
Noise & Vibration
These two tire sizes have nearly identical diameters and sidewall heights, so noise and vibration levels are very similar.
Both absorb and dampen vibrations effectively to provide a smooth, quiet ride for passengers. Any differences would be negligible.
Durability & Wear
With more rubber meeting the road, the wider 235/45R17 tires can withstand more wear over time before needing replacement.
And with equivalent load ratings, both have similar durability regarding sidewall strength and puncture resistance. Even treadwear should be comparable.
Adverse Conditions
Performance in rain, snow, and light off-road conditions is similar between both tire sizes. The marginally higher ground clearance of the 235 offers a slight advantage, while the 225’s more minor contact patch provides a quicker response. But overall traction and capability are comparable.
Speedometer Difference
The 235/45R17 size causes a 0.28 mph higher speedometer reading than the 225/45R17 at an actual speed of 20 mph. This minor discrepancy has a negligible impact on driving.
Can I use 235/45r17 instead of 225/45r17?
Yes, you can replace 225/45R17 tires with 235/45R17 tires. The overall diameter difference between the two sizes is only 0.35 inches (9mm), which is a 1.4% difference.
This is well under the 3% limit recommended for direct replacement without any modifications or clearance issues.
Additionally, when replacing tires, you must match or exceed your original tires’ load rating. As long as the 235/45R17 tires you select have the appropriate load rating for your vehicle, they can directly replace the 225/45R17 size.
