245 vs 305 Tires
The numbers 245 and 305 refer to the width of the tire, measured in millimeters. The tire size 245 is 60 mm wider than the 305 tire size. The 245 tire is 245 millimeters wide, while the 305 tire is 305 millimeters wide. The choice of tire width depends on the type of vehicle, driving conditions, and personal preference.

The 305 tires can handle better than the 245 tires. The wider tire size (305) provides a larger contact patch with the road, which leads to improved traction and better steering ability. The larger contact patch also provides better weight transfer during cornering, which results in better balance and stability.
Additionally, the larger size of the 305 tires provides a more responsive and heavier steering feel, which is beneficial for performance vehicles. Overall, the improved traction, stability, and responsiveness provided by 305 tires make them handle better than 245 tires.
The effect of tire size on fuel economy can vary depending on the vehicle and terrain. Generally speaking, larger 305 tires will typically have a negative impact on fuel economy due to their increased rolling resistance. This is because the larger tire has more rubber and air within it, which causes more friction between it and the road surface.
On the other hand, smaller 245 tires usually provide better fuel efficiency since they require less energy to move. While this may sound like an obvious answer, several factors need to be considered when considering the impact of tire size on fuel economy.
These include vehicle weight, type of terrain being driven in (e.g., flat roads or hilly terrain), driving conditions (e.g., stop-and-go traffic or highway driving), and type of tire (e.g., all-season or winter). All these elements play a role in determining how much fuel a vehicle consumes when driving with either tire size.
Generally speaking, a tire with a smaller width, such as a 245 tire, would typically be more comfortable than a wider tire, like a 305 tire. This is because a wider tire has a larger contact patch with the road, which can result in more road noise and a harsher ride.
It is important to note that narrower tires often come with a higher sidewall ratio. A higher sidewall provides more surface area for the tire to absorb the impact of uneven road surfaces, which can help to mitigate any negative effects on the ride quality.
Wet & Snow
I’d like to share with you the secret behind 245 tires providing better grip in challenging weather conditions. It all comes down to their higher pressure per square inch rating. Unlike wider 305 tires, the narrower 245 tires have the ability to penetrate snow, slush, and rain more effectively.
While it’s true that a wider contact patch does give you better traction on dry roads, it becomes a hindrance when it comes to cutting through snow and reaching the ground. So, next time you’re facing inclement weather, consider switching to 245 tires for better traction.
The traction provided by a tire depends on several factors, including the tire’s compound, tread pattern, and tire pressure. Generally, a wider tire (such as a 305) will offer more grip in the dry than a narrower tire (such as a 245) because it has a larger contact patch with the road surface. However, other factors, such as the tire’s tread design, compound, and pressure, will also play a role in determining its traction.
It’s interesting to note that the difference in tire size between 245 and 305 can drastically affect your speedometer and odometer readings. The difference in tire size can cause a discrepancy of up to 6% when measuring your speedometer reading and up to 4% when reading your odometer.
This means that if you are driving at a certain speed with 245 tires, your speedometer could be reading slower than it should be with 305 tires. Similarly, the odometer could show that you’ve travelled fewer miles than you actually have.
In general, 245 tires are likely less expensive than 305 tires due to several factors. First, wider tires like 305 require more materials to manufacture, including more rubber and steel, increasing their production costs.
Additionally, wider tires are typically designed for higher-performance vehicles and may include additional features, such as specialized tread patterns and compounds, which can add to the cost. On the other hand, narrower 245 tires may be more commonly used on a wider range of vehicles and therefore have a larger market demand, which can help to keep prices lower.
The weight-carrying capacity of a tire is determined by its load index, which is indicated by a number on the sidewall of the tire. The load index represents the maximum weight a tire can safely carry at its maximum recommended pressure. So, whether a 305 tire can carry more weight than a 245 tire depends on the specific tire model and its load index.
Generally, wider tires tend to have a higher load index than narrower tires, but this is not always the case. It is important to check the load index of the specific tire you are considering and ensure that it is suitable for the weight of your vehicle.
