225 vs 245 Tires
The section width is the main difference between 245 and 225 tires. A 245 tire is 20mm wider than a 225 tire, which can affect a vehicle’s performance.
245 vs 225 Tires
| 245 Tire | 225 Tire |
|---|---|
| Lower Gas Mileage due to more rolling resistance and rotational mass | Better Gas Mileage due to less contact patch and rotational mass |
| More comfortable ride due to wider contact patch and taller sidewall | Less comfortable but more nimble due to narrower width |
| More aggressive, beefier aesthetic appeal | More aerodynamic, positive impact on vehicle aerodynamics |
| Improved stability and traction, especially off-road | Enhanced handling and quicker response on road |
| Potentially more road noise but dampens vibrations better | Quieter on smooth roads but more vibration felt from road irregularities |
| Endures impacts better but may cause more component wear due to weight | Exhibits even treadwear, potentially longer lifespan |
| Higher load capacity due to larger contact patch | Lower load capacity compared to wider tire |
| Better traction in mud or off-road conditions | Can cut through snow/ice more effectively due to narrower width |
Gas Mileage
With a slightly smaller contact patch and less rotational mass, 225 tires generally confer better fuel efficiency, an aspect crucial for daily commuters and long-distance travelers.
The larger 245 diameter and width might detract from fuel efficiency owing to increased rolling resistance and rotational mass. Larger tires with heavier weight give you less gas mileage.
Ride Comfort
The 245 wider tires generally offer a more comfortable ride than the 225 tires due to their wider contact patch and taller sidewall. However, the 225, being slightly narrower, would be more nimble.
Larger 245 tires give you better off-road performance than the 225 ones, but smaller tires are better for on-road performance.
Aesthetics
The 225 tires contribute positively to vehicle aerodynamics, whereas 245 tires can offer a more aggressive and aesthetic appeal but may hinder aerodynamic efficiency slightly. Those looking for a beefier look tend to prefer the 245.
Handling & Stability
The 225 tires typically offer enhanced handling and quicker response on paved roads due to their narrower width.
Conversely, 245 tires present improved stability and traction over uneven surfaces or gravel, particularly in off-road scenarios.
Noise & Vibration
The 225 tires may provide a quieter ride on smooth surfaces but might transmit more vibrations from road irregularities compared to the wider 245 tires.
Larger 245 tires, especially those with aggressive treads, might generate more road noise but could also dampen vibrations better due to increased air volume and sidewall height.
Durability & Wear
The 225 tires can potentially exhibit even wear and potentially longer tread life due to their shorter contact patch and lighter weight, putting less stress on components.
Larger 245 tires, while potentially enduring more impacts and absorbing more stress on sidewalls, might introduce more wear to vehicle components due to their added weight.
Load Capacity
The load capacity of a tire increases with tire width. As the 245 tire is wider than the 225, it has a larger contact patch, which can distribute the weight over a wider area. This means the 245 has a higher load capacity in most cases.
Adverse Conditions
The narrower 225 tires can sometimes navigate snow and ice more effectively by cutting through to the road surface compared to the wider 245 tires.
However, larger 245 width tires provide advantageous traction in specific off-road or muddy conditions, while 225 would not fare as well.
What Is The Difference Between A 225 And 245 Tire?
The main difference between 225 and 245 tires is their width. A 245 tire is about 20mm wider than a 225 tire.
This extra width allows for a larger contact area between the tire and the road, which helps distribute the weight of the car more evenly across all four corners.
As a result, the car has better handling and stability when taking corners.
How Much Wider Is A 245 Tire Than A 225?
The 245 tire is 20 millimeters wider than the 225 tires. This means that the width difference between these two tire sizes is approximately 0.8 inches (since 1 inch is equivalent to 25.4 millimeters).
It’s important to note that the difference in width can vary depending on the specific make and model of the tire.
How Much Taller Is A 245 Tire Than A 225?
The height difference between a 245 tire and a 225 tire depends on the specific aspect ratio of each tire. Let’s assume the tire sizes mentioned are in millimeters and share the same aspect ratio. Suppose the 245 and 225 tires have an aspect ratio of 45 (standard for performance and passenger car tires).
So, the sidewall height of the 245 tires would be 245 x 0.45 = 110.25 millimeters, and the 225 tires would have a sidewall height of 225 x 0.45 = 101.25 millimeters.
The difference between the two is 9 millimeters (110.25 – 101.25). However, since there are two sidewalls (one on top and one on the bottom), the total height difference between the two tires would be 18 millimeters.
In short, the 245 tire size is 18mm taller than the 225 tire size. It is important to note that the difference in height between two tires will vary depending on their aspect ratio and rim size.
Can I Replace 245 Tires With 225?
Yes, you can replace 245 tires with 225 tires if the overall diameter difference between the two tires is less than 3%, replacing one with the other should be fine.
The overall diameter of a 245/45r17 tire is 25.68 inches, whereas the 225/45r17 tire has an overall diameter of 24.97 inches.
Calculating the difference between these two tire sizes comes to approximately 0.71 inches or about 2.8%. Since this is less than the recommended 3% difference, using a 245/45r17 tire instead of a 225/45r17 is feasible.
What Does 245 Mean On A Tire?
The number 245 on a tire refers to the tire’s width in millimeters, measured from sidewall to sidewall. You can convert 245 mm to inches by dividing it by 25.4 mm/inch, resulting in 9.65 inches. Therefore, a 245 tire would have a width of approximately 9.65 inches.
