What should the PSI be on a trailer tire?
What should the PSI be on a trailer tire?
Trailer tires usually do not have a recommended and maximum psi indication so I am curious if the tries on the camper are ST tires or regular passenger vehicle tires. On a regular trailer tire you would inflate it to the max psi indicated on the tire because trailer tires are built with a thicker sidewall to handle more vertical load.
What’s the maximum pressure for an extra load tire?
Extra Load tires of the same size will typically have the same load capacity at the same pressure as the Standard Load tire. However, they have added load capacity above certain pressures. Light and Standard Load tires have a maximum capacity pressure rating of 35-36 psi and Extra load tires have a maximum capacity pressure rating of 41-42 psi.
How big of a tire can I fill with 35 psi?
That is the size you will want to stick with. Any given size tire can have different load ranges. For example an ST175/80-13 load range B will have a capacity of 1,100 pounds at 35 psi. But a load range D in the same size, # AM10210, is rated for 1,610 pounds at 65 psi.
What should the pressure be on a SL tire?
The maximum allowed pressure listed on a tire’s sidewall can be higher however. Some tires list 44 psi and many higher speed tires will list 50-51 psi. This added pressure does nothing for load capacity. Pressures above 35-36 psi for SL tires and 41-42 psi for XL tires will not increase the load capacity of the tire.
How to determine the right air pressure to fill a trailer tire?
Check the camper frame and there should be a sticker or plate that lists what tire size should be on the trailer. It could also be in the owners literature. That is the size you will want to stick with. Any given size tire can have different load ranges. For example an ST175/80-13 load range B will have a capacity of 1,100 pounds at 35 psi.
What should fuel pressure be running down the road?
Normal fuel pressure should float about 14-15 PSI running down the pavement. It should never fall below 10 PSI at all. Here is a colorize fuel pressure gauge to give you a clue of the fuel pressure span you want.
How much gas does it take to tow a camper?
How much more will depend on the length of your trip as well as how many trips you plan to go on each year. A truck that normally gets 15 miles per gallon, but only gets 8 miles per gallon while towing will consume an additional 17.5 gallons of fuel for a 300-mile round-trip.
That is the size you will want to stick with. Any given size tire can have different load ranges. For example an ST175/80-13 load range B will have a capacity of 1,100 pounds at 35 psi. But a load range D in the same size, # AM10210, is rated for 1,610 pounds at 65 psi.
