You will notice that your tire pressures are a fair bit higher than what you set them at initially. After a couple of laps around the track you come into the pits and you immediately check your tire pressure gauge. Imagine that you are about to go out on track, and you set your tire pressures to 40 PSI on all 4 tires. Your hot pressure reading will be higher than the cold pressure reading. The hot reading is when you have just come off the circuit and your tires are hot from friction caused by the track. The cold reading is when the tires have not been used yet. It means that your tires have a ‘cold’ pressure and a ‘hot’ pressure. Your tires will not have the same PSI or temperatures at the end of the session as when you started though, and this is important to remember. This window is the pressure and the temperature that will give your tires the right amount of grip. Tire pressures have an operating window in terms of temperatures and PSI. General Tire Pressure Basics Operating Window So, let’s go over the basics of tire pressure and how you can use it properly. You can use different tire pressures to change the amount of time it takes for your tires to heat up and even overheat. Tire pressures can change how much grip your car has and how long that grip lasts. Although these issues can be resolved by adjusting the chassis set up, often it’s as straightforward as running on the wrong tire pressures, so never neglect this seemingly small set up component. Usually they’re trying to find the perfect balance between oversteer and understeer. They then ‘pass’ this information to the road, making the car do what you want it to do.ĭrivers often change complicated settings on their set ups when they struggle with the car. So, they essentially must interpret what you as the driver are doing with steering and accelerating or braking. The primary reason why your tire pressures are so crucial is due to the fact that the tires are the only part of the vehicle that contacts the road. Always remember to refer to your tire manufacturer’s guidelines to ensure you are using the right tire pressures. These will give you better grip and will also be able to handle the higher pressures. Testing To Find Your Preferred Pressures (Especially For Racing)įor this article we are going to assume you are on track with performance tires.How The Type Of Car Affects Tire Pressures.This could be a problem if the boat (including outboard, batteries, fuel and gear) plus the trailer weighs 2,400 pounds. If you are in the habit of airing those trailer tires to just 35 pounds (your truck tires take 35 pounds, after all) the combined tire capacity drops to just 2,200 pounds. If the tire pressure is reduced to 40 psi, the individual tire-load rating drops to 1,190 pounds (2,380 pounds combined), or 110 pounds less than the trailer capacity. At 50 psi, each tire is rated to carry 1,360 pounds, or a combined 2,720 pounds for the pair of tires. A single-axle boat trailer with a 2,490-pound GVWR (trailer plus cargo) rolls on ST175/80R13C tires with a max trailer tire PSI of 50 pounds. Underinflated and thus overloaded tires are the leading cause of trailer-tire failure the tires overheat and fall apart. If you roll out of the driveway towing your boat with less than the max psi in the trailer tires, you have effectively reduced the load capacity of the entire trailer. The load capacity of the trailer was determined with that specific tire pressure as a factor. Tire pressure determines the load the tire can safely carry. Maintaining that trailer tire PSI is critically important to towing safety. In fact, the correct tire pressure for your boat trailer is almost always the maximum-rated pressure for that tire, which is molded right on the sidewall. Shutterstockīoat-trailer tires require a lot of air pressure - in most cases, between 50 and 65 psi. The cost, due to accelerated wear, of improperly inflated trailer tires pales in comparison to putting the lives of other motorists, your passengers and yourself at risk.
