However the proper cold pressure is determined by the vehicle manufacturer after they determine what load the tire actually carries based upon vehicle design.
Rv tire pressure calculator.
See our current load and inflation tables.
Calculate the new tire pressure needed when changing tire sizes to match the vehicle s original tire load capacity.
Goodyear rv tires including st tires goodyear truck tires including 17 5 tires bridgestone truck tires.
Checking tire pressure should be part of the service of every rv.
All rvs have a plate somewhere that will tell you what the manufacturer recommends for maximum tire inflation pressure.
Too much weight can cause stress on your rv s suspension system brake failure shock absorber damage handling and steering problems irregular tire wear and possible tire failure.
The pressure molded onto the tire sidewall is the highest pressure the tire is rated for at a maximum load as determined by the tire manufacturer.
Firestone truck tiredata book.
And pressure on sidewall rv tires 10 wheel diameter 16 for rv use only michelin displays tire loads per axle end in the load and inflation tables as we recommend weighing each axle end separately and using the heaviest end weight to determine the axle s cold inflation tire pres sure.
Tire pressure should be based on the load being carried by the tire.
The recommended pressure on the tires is 110 psi but all the tires on rv are at 90 psi.
Changing tire sizes typically brings a change in tire load rating which may require the new tire s air pressure to be altered to acheive the original tire s load capacity.
For example the winnebago supplied sticker on our travato lists 80 psi cold for the rear tires.
Tire pressure is what enables your rv tire to support loads.
The rv s manufacturer looks at the weight of your rv and specs a tire in that load range then takes an inflation table that shows what the tire pressure should be for that tire at that load.
Dot code lookup.
What pressure should be used.
For control of your rv it is critical the tire pressures.
That s what they put on the sticker.
The important question of course.
Generally speaking when you see a tire pressure listed anywhere sidewall door jamb inflation table the pressure refers to a cold pressure.
Should i leave them at 90 psi.
To select the right load and inflation table for your commercial tires locate your tire size then match your tire s sidewall markings to the table with the same sidewall markings.
Overloading your tires can have serious consequences for passengers and your rv.
They take into account that the tire will heat up and the pressure will increase.
I just recently bought a diesel pusher.
