Tire Pressure on a 2860

New RV'r here.

Can anyone tell me the correct or recomended tire pressure to run on the front and rear dual tires on a 2007 Sunseeker 2860 with 225/75/16 size tires?

Thanks in advance for the help.

Jon

there should be a decal located within the camper telling you the recomended pressure unless it was removed . cupboard door ? cupboard side ?
some times in a cubby underneath ?

What do the tires sidewalls say? Personally since most MH's are loaded to about the maximum of the chassis I would run max on the sidewalls. Now, if you had done your due diligence and had scaled weight for each corner it would be easier to give you a better answer.

Our new 2300 is 65 psi for front and 80 psi for dual rears. But the key is to look at the sticker located on the frame of the drivers door and do what it says. And that assumes you look at the other sticker with max weigh info and do not exceed it.

This is without a doubt, the best answer.

Weigh all four corners - they will be different
inflate that axle's tires to highest the tire pressure on the tires inflation chart for the heaviest weight.

Rule of thumb:

All tires on an axle must be inflated to the same PSI based on the actual load on the most loaded wheel on that axle.

If no scale to determine the actual loads: the tire placard is USUALLY safe. Just might not be correct for how you loaded your camper. Placard inflation pressures normally include RIDE as well as "average," not maximum, loading (otherwise you would not need a placard - just a sign that says "read the tire").

Not to ignite a firestorm but I totally disagree. Here's why: The PSI's on the sidewalls of the tire are VERY generic for that tire. Remember that tire may go on a wide cross section of vehicles. You want to use the placard as it is specific to the vehicle & is in line with how the vehicle was engineered.

I think we are saying the same thing. Ride and usage (normal load) determine the placard weight. For example my GMC 2500 has 80 PSI E rated (80 PSI max) tires on all four wheels; yet the placard states 65 PSI front and 70 PSI rear. When hitched for towing I run 80 PSI rears and 70 PSI fronts due to the axle loads with the camper on.
