The amount of pressure in your tires can have a significant effect on the fuel efficiency of your vehicle. This is because the more air in the tire, the less resistance there is to rolling.
It is important to keep your tires properly inflated at all times. This will also help to extend their lifespan, as well as improve safety and reduce wear on suspension components.
Tire pressure should be checked periodically with a tire gauge and adjusted when necessary.
What tire pressure should I run on my travel trailer?
Our recommendation for all tires on multi-axle trailers: The pressure associated with a maximum load of 85 PSI or less should be inflated no less than the PSI indicated as follows: Option One: Per the minimum tire requirement stated on the vehicle’s Certification Label.[1]
How much psi should a trailer tire have?
What psi Should Trailer Tires be Inflated To Trailer tires should always be inflated to the maximum air pressure indicated on the tire. The tire on tire and wheel combo #AM30620 for example should be at 90 psi.[2]
Should trailer tires be inflated to max psi?
When it comes to trailer tires you always want to have them inflated to their max psi when cold. Not only do you get the full capacity at the max psi, you also will generate less heat in the tire since there won’t be as much flex in the sidewall, you’ll get better wear and better fuel mileage.[3]
Where do you find the proper PSI for a trailer?
Trailer tires can look fully inflated and be below the safe air pressure. Find the maximum tire pressure by looking at your tire sidewall. Look for the small notation “Max. Load” followed by a PSI number (80 in the example below).[4]
Is 65 PSI too much for trailer tires?
If your trailer placard and/or your load weight requires 65 psi then you cannot run faster than 65 mph on load range D tires without increasing the risk of tire failure. You could buy load range E tires and run them at 75 psi if you wanted to do this.[5]
Should I increase tire pressure when towing?
For towing, tires should be inflated to the max cold pressure listed on the sidewall of the tire. Even if you’re only towing half the weight your vehicle/tires are able to handle, half the max cold PSI DOES NOT support half of that maximum load, there’s a steep drop off of load carrying capability compared to pressure.[6]
Why do trailer tires wear out so fast?
That said, rapid or significantly uneven trailer tire wear can be caused by: Riding with the wrong tire pressure. Exceeding your tires’ load capacity. Trailer misalignment or bent wheels from hitting curbs, potholes or debris.[7]
Is 90 psi too high for trailer tires?
This is the psi rating that the manufacturer has tested and approved to be safe with the weight rating that is listed on the tire. The psi will actually increase some during travel due to heat build up but the manufacturer has already accounted for this. The 90 psi rating is actually normal for that size tire.[8]
Is 80 psi too high for tires?
The 80 psi is required if the tire is operating at rated load. You most likely have a load range E tire.[9]
How much air do you put in a 10 ply tire?
All load range “C” tires (the old “6-ply” rating) can be inflated to 50 psi, “D” (8-ply) to 65 psi and “E” (10-ply) to 80 psi.[10]
Do you need to balance travel trailer tires?
The answer is yes, you should. Although you may meet RVers and travel trailer owners who disagree, balancing your travel trailer tires is actually necessary for improved performance, tire longevity, and safety factors. Passenger vehicle tires need to be balanced for ride stability and comfort, as well as for function.[11]
Does tire pressure affect trailer sway?
Check the tire pressure. Under-inflated tires reduce the load-carrying capacity of your vehicle or trailer which can cause sway.[12]
