Default Tire Pressure

I am installing the tires on my RV-7A and cannot find the proper air pressure for the main and nose tires

Default Tire pressures

Have had good luck with 45 mains & 40 nose. Some run less on the nose to reduce shimmy but risk flats due to tire to rim slip &/or tube scuffing.

Timely post Bob! I'm doing some taxi test and am having some shimmy issues. Looks like I need to boost the tire pressure!

I run 35 all around in my 9a. So far so good with over 100 hours in the original tires at this time.

No such thing as "proper" tire pressure. Some prefer more, some prefer less. In general, I prefer as little pressure as practical. In my experience, excess pressure just wears out the center tread faster. I look for the pressure that gives the most even tire wear. IMO, 40 is on the high side in an RV. But you don't want so little that you risk rolling the tire off the rim. There's a wide margin of usable PSI.

Just because its "experimental" doesn't mean there aren't recommended or "proper" tire pressures. Sure you can choose to run whatever you like but folks smarter than me have already figured most of this stuff out so I go with it.

Articles/FAQ from desser

Link to "Standard tire pressure chart".

The majority are running tires way too soft.

Listen to Walt, read the chart. 500x5 6 ply = 50 psi unloaded
