35 psi in the mains of my RV-6 seems to work well for me.

I run 40 in the mains, 45 in the nose. No shimmy, no issues (no worries?)

I have the Beringer tubeless nose wheel and Dresser recaps on the mains.
I adjust pressure to 50 in the nose and 36 in the mains. From experience, they loose about 5psi each in 60 days. I readjust pressures every 60 days.

Reviving this old thread...

There are so many different recommendations on this forum. I asked Vans, and they recommend 25 PSI on the mains and 30-35 PSI on the nose, but say to decide what works best for yourself. It's interesting that their recommendations are much lower than what most folks report using.

Those are our recommended operating pressures, but you'll end up deciding what works best for you, just like all the other guys.

Subject: RV-7A recommended tire pressures

I?m looking for recommended tire pressures for the Vans RV-7A. I see initial pressures of 25 psi on the mains and 30-35 psi on the nosewheel in Section 10 of the build manual, but it?s unclear if these are the recommended operating pressures. Vans Airforce has extensive discussion on the topic and people seem to operate anywhere from 25 to 50 psi.

Thank you,

David Harris

God, that seems low to me, at least for the mains. 25 PSI? Mine look positively flat to my eye when they're that low

I run 38-40 PSI, no issues.

Default 7A Tire pressure

Always 45 psi on nose and main tires. Shimmy has not been a problem.

I put air in the tires on my RV-6 till it looks just about right.

IF I put a tire pressure gauge on the tire after it looks just about right, the tire pressure will read 35 psi.

lowering the P from 40 to 30psi killed the shimmy on my -6
