The answer to this question is not so straightforward. It all depends on where you are and the terrain you are driving on. For example, if you are in a desert, it is best to fill the tires with as much air as possible to avoid punctures. But if you are driving in an area with snow or ice, it is best to keep the tires half-filled with air because they will have better traction and control.
Should I inflate trailer tires to max PSI?
It’s really important not to overload trailer tires. Overloading tires can cause premature wear and increase the risk of tire failure. The “Max. Load” information stamped on the sidewall indicates a tire’s load capacity when it’s inflated to the maximum PSI.[1]
What pressure should I inflate my RV tires to?
The tire pressure on an average 16″ RV tire can be anything between 35-80 PSI or 280-550 kPa.[2]
Should you fill tires to max load PSI?
What happens if you inflate your tires to the max PSI? Your tires’ max PSI almost always exceeds the recommended pressure. It isn’t advisable to fill your tire to this pressure for everyday driving. At max PSI, your car does not handle as well, braking is impaired, and you could risk dangerous blowouts.[3]
How much air do I put in my travel trailer tires?
Thankfully, the answer is simple (except when it’s not). You go by the sticker in your RV (or motorhome, car, or truck). The pressure listed on the sidewall of the tire is the “max cold pressure,” not a recommendation for inflation. It’s the most air pressure that should ever be in that tire.[4]
Is 80 psi too high for trailer tires?
Helpful Expert Reply: Trailer tires should be inflated when they are cold and should be inflated to the max psi rating on the sidewall. In your case you would want to run 80 psi. If you don’t inflate them to the max psi figure you will lose weight capacity and potentially cause the tires to overheat and fail.[5]
Is 90 psi too high for trailer tires?
The 90 psi rating is actually normal for that size tire. For example, the Taskmaster 4.80-12 Bias Trailer Tire # TTWSF48012C has a Load Range of C which means 990 lbs at 90 psi.[6]
What should my tire pressure be when towing a travel trailer?
at 40 for general driving and 50 for heavy towing (51 is max). Rides a little more firm in general, but helps with mileage. When towing you have enough weight on the tires to mash them down flat so they wear even. With a load and lower pressure they generate heat and wear the outside much faster.[7]
What is the recommended tire pressure for 65 psi max?
Under Pressure In other words, if a tire reads “Max Load single: 3650 lbs at 65 psi cold” then 65 psi is the minimum cold-air inflation pressure necessary to carry the maximum load figure.[8]
How do I inflate my RV tires?
Adding air to the outside tire is easy – you just remove the stem cap, attach the air hose and chuck to the valve stem, fill the tire while checking the pressure, then replace the stem cap. Inflating the inside tire is when it gets fun.[9]
Why do dealers overinflate tires?
Tires are overinflated during the shipping process, so as to help prevent the flat spot from forming in the tire as it sits for days on in during the shipping process. It is supposed to be part of the delivery check process that the service department deflates the tires to the proper pressure.[10]
What is the 4 psi rule?
Ideally, they should be about 4psi above the cold pressure. If the pressure is more than 4psi above the cold pressure, you should add more air. That is because there is too much friction, which builds up more heat than desirable. Conversely, if they are less than 4psi above cold pressure, the cold pressure is too high.[11]
Is it better to over inflate or Underinflate tires?
Under-inflated tires are just as dangerous and costly. Like over-inflated tires, under-inflated tires also cause blowouts. When a tire is under-inflated, more of the tire’s surface area touches the road. This increases friction, which increases heat and leads to advanced wear.[12]
