[Land-speed] Tire Valves

[Kirkwood]

Thanks, JT. . .  good idea. I also checked the Machinery's handbook and the
recommended engagement for hand tight is .161'' which is about 4-5 threads.
For high pressure they say ''longer thread engagement is used''  but give no
recommendation. Me thinks added thickness is a good idea.

Wall thickness concerns...add two bosses, 180 degrees apart on the inside of
rim, drill and tap one and balance the rim before adding the tire.
