What are the best tire compounds and pressures for wet and dry traction?
Tire compounds and pressures are crucial factors that affect the traction, handling, and performance of your vehicle. Depending on the weather and road conditions, you may need to adjust your tire settings to optimize your grip and stability. In this article, we'll explain how tire compounds and pressures work, and what are the best choices for wet and dry traction.
Tire compounds are the materials that make up the tread and sidewall of your tire. They determine how soft or hard your tire is, and how well it adapts to different surfaces and temperatures. Generally, softer compounds provide more traction, but wear out faster and overheat more easily. Harder compounds last longer, but have less grip and flexibility. Tire manufacturers offer different grades of compounds, such as summer, winter, or all-season tires, to suit various driving conditions and preferences.
Tire pressures are the amount of air inside your tire, measured in pounds per square inch (psi). They affect how much contact area your tire has with the road, and how much it deforms under load. Generally, lower pressures increase traction, but reduce fuel efficiency and handling. Higher pressures decrease traction, but improve fuel efficiency and handling. Tire manufacturers recommend optimal pressures for their products, based on the vehicle weight, load, and speed. However, you may need to adjust your pressures depending on the weather and road conditions.

The tire pressure should be set per your vehicle manufacture recommendation. This can be found on the inside of your drivers door jam sticker or in your owners manual. This will provide the optimal tire tracking and fuel mileage for your tires. Increasing tire pressure will not only wear out your tires sooner, but also may change the handling of your vehicle. Raising the air pressure within the maximum psi, located on the sidewall of the tire, is recommended when hauling extra weight such as a heavy load in a truck/van or hauling a trailer. Lowering the air pressure should never be done unless when operating on loose soil conditions such as in sand. The only application I ever used this scenario was in the military in the desert.
Wet traction is the ability of your tire to grip the road when it is wet or slippery. Wet traction depends on several factors, such as the tire compound, pressure, tread pattern, and depth. Generally, softer compounds and lower pressures improve wet traction, as they allow more flexibility and contact area for your tire. However, you also need a good tread pattern and depth, to channel water away from your tire and prevent hydroplaning. Hydroplaning occurs when your tire loses contact with the road and skids on a layer of water. You can check your tread depth by inserting a penny into the tread groove. If you can see the top of Lincoln's head, your tread is too worn and you need to replace your tire.
Dry traction is the ability of your tire to grip the road when it is dry or smooth. Dry traction depends on similar factors as wet traction, but with some differences. Generally, harder compounds and higher pressures improve dry traction, as they reduce the rolling resistance and heat generation of your tire. However, you also need a balanced contact area and pressure distribution for your tire, to prevent uneven wear and loss of grip. You can check your tire pressure by using a gauge or a sensor. You should check your pressure regularly, especially when the temperature changes, as hot or cold air can affect the pressure inside your tire.
When selecting the best tire compounds and pressures for wet and dry traction, there is no single solution that works for all vehicles, driving styles, and preferences. However, some general guidelines can help you make an informed decision. For wet traction, a softer compound, lower pressure, and deeper tread are recommended. On the other hand, for dry traction, a harder compound, higher pressure, and shallower tread are suggested. For mixed conditions, an all-season compound with a moderate pressure and balanced tread may be suitable. Finally, for extreme conditions like snow, ice, or mud, a specialized compound with a specific pressure and dedicated tread should be chosen.
Adjusting your tire compounds and pressures for wet and dry traction is not difficult, but it does require some knowledge and tools. You can either do it yourself or consult a professional mechanic or tire specialist. To ensure optimal performance, it's important to check your tire condition and pressure regularly, and compare them with the manufacturer's recommendations. Choose your tire compound and pressure based on the weather and road conditions, as well as your driving needs and goals. A gauge or sensor is needed to measure tire pressure, while a pump or valve is used to inflate or deflate the tire. Additionally, use a penny or tread depth gauge to measure tread depth, and a tire rotation or replacement service to maintain tread wear. Finally, test your tire performance on a safe and controlled road or track, making adjustments as needed.

Do your own research when buying tires. Tirerack.com is a good source for customer ratings and professional testing. Also, choose a tire for your driving conditions. For example: I use a good all season tire from April until end of October. Then I install a high rated snow tire for from October it I. April since I do drive into the mountains several times I the winter and we live on a hill in my neighborhood.
