I have a set of Rickson wheels coming for my 1950 3/4 Ton pickup and they'll soon get wrapped with 8R19.5 tires. I know it's common to inflate to 100psi when they are used on commercial trucks, but since my truck is considerably lighter, what pressure should I inflate to? Are there advantages (traction, comfort etc...) to going with a lower air pressure? | | | | | Joined: Feb 2004 Posts: 29,752 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,752 | That one will feel like you're riding around on solid rubber tires if you go that high on the pressure! As long as you're not approaching the maximum load weight on the tires, you can reduce the pressure quite a bit. I'd suggest starting out about 60-65 PSI and see how the ride feels. As long as you don't drop the pressure enough to make the sidewalls flex excessively and build up enough heat to make the plies start to delaminate, reducing the pressure only drops the maximum weight rating of the tire. Watch out for uneven tread wear which would show up as more wear on the outer edges if the pressure gets too low.
