I run mine at 45--50 psi.

Thanks guys. I'm running the Matco wheel/brake assembly that came with the RV-7 kit and I've run into the clearance issue with the caliper. I've measured the clearance from 20 through to 65psi and plotted it. At 20 psi I have 0.032" at this worst case location, at 65psi I have 4 thou, and based on the shape of the curve I estimate contact at around 90 psi. I see some earlier posts regarding shimming things to improve the clearance, however it's not exactly clear what to shim. If I am to bother shimming say a 0.063" further out , in my mind that would require a 4.5" diameter disc to be fabricated between the brake rotor and the inner rim half, an 0.063" thicker shim that is currently in place against the inboard bearing, and a 0.063" thinner shim between the outer bearing and the axle nut. This would mean that I would not have to drill a new axle position, which I really do not want to do.
Or, I could just leave it at the current clearance and see how things go?
How are others achieving the desired clearance, and what should that target clearance be?

Great thread guys!
In a mid life crisis I've started my RV8 build. Lucky enough to have time, so empennage finished in 5 weeks.. fuselage kit will be here in 4 weeks time. I'm currently operating a 180hp Husky from a 570' strip with a wall at each end, so probably won't be taking the RV there (but I'll no doubt give it a go later!). Dropping from 26" wheels to standard Vans wheels was too much of a culture shock, so Ive ordered Grove one-piece gear, 6 inch wheels and plan on putting 600x6 tyres on, with James wheel pants for the RV10. My Husky guru, Tom Dietrich uses the same pants with 700 x 6 wheels on his Allison powered (450shp) hot rod, Pocket Rocket... take a look on youtube, they look great!. I'll let you know how I get on with them in a short while...

Good call Bruce!
I am certain you will be glad you made the swap. I have found after 10 years of "use and abuse" that the 380's way outperform the 500X5's on my (former) Rocket and my (current) RVX.
Steve Sampson introduced me to them while he was building his RV4 masterpiece "G-IKON" and I haven't even considered going back to the 500's since.*


*Side note: Landings on soft turf, mud and gravel are vastly improved by the 380's however, handling on pavement is also superior. BTW, I have found 30 PSI to work well on most surfaces.

you can get 6" wheels for a 1 1/4 axle from Grove... same as supercub version, then fit RV10 wheel pants.
