kerry Posted September 5, 2011 Report Share Posted September 5, 2011 My book tells me 30 lbs for tire pressure. I tend to keep my tires at 34 lbs because visually 30 lbs looks to low especially the nose wheel. My tires are old but treads are in good shape. I'm wondering if the age of the tire has anything to do with them looking low at 30 lbs. Cessna owners tell me their suprised that mooney only take 30 lbs of tire pressure. Any input out there.

stevesm20b Posted September 6, 2011 Report Share Posted September 6, 2011 I have a M-20B and just installed a new set of tires and tubes. I didn't notice any difference between the old and new tires inflated to the same pressure. My old tires still had tread left on them but one of the tires went flat. Then stem on one of the tubes cracked and broke off. Fortunately it happened while it was parked in the hanger and not when I was flying. So, I replace all the tires and tubes just to be on the safe side. My book says 24 to 30lbs. I keep mine at 30lbs, only because the airplane is easier to push in and out of the hanger inflated to 30lbs compared to 24lbs. Mooneys have a pretty stiff gear, and I have noticed when the tire pressure is on the low side, the ride is not as bumpy when taxing. That may be why you don't run as much air in the tires on a Mooney compared to a Cessna. Quote Link to comment Share on other sites More sharing options...
rbridges Posted September 6, 2011 Report Share Posted September 6, 2011 I put more air in the tires, and I noticed that I rolled a lot longer on the runway after landing. I've always thought the same thing that they looked low even with 30lbs. Quote Link to comment Share on other sites More sharing options...
Piloto Posted September 6, 2011 Report Share Posted September 6, 2011 The most significant difference when you put more pressure on the tires is when you have to push the plane by hand, specially on dirt or grass. It makes it much easier. But too much pressure makes the plane prone to bounce on touch down. Also to skid when brakes are applied on the roll out.

danb35 Posted September 6, 2011 Report Share Posted September 6, 2011 Not all Mooneys have (or require) tire pressure markings on the exterior--I think that started only with the J models. Quote Link to comment Share on other sites More sharing options...

rdav Posted September 10, 2011 Report Share Posted September 10, 2011 I inflate both the mains and the nose to 30 lbs in my M20C, but it always seems that the nose wheel looks a little flatter than the mains. Does anyone else notice this, or is my imagination playing tricks on me? Has anyone seen a noticeable change in the way the tires look as the aircraft is loaded to forward vs aft C of G? With full tanks and no passengers, my CG sits at 44.6 inches, which is near the middle of the limits. Quote Link to comment Share on other sites More sharing options...

carusoam Posted September 10, 2011 Report Share Posted September 10, 2011 Phil, Your C looks much newer lately! How's your instrument panel working? Best regards, -a- Keeping in line with the thread.... My C always parked in the exact same space, so a low spot formed in the pavement under the front wheel, making it look even lower.

PTK Posted March 20, 2012 Report Share Posted March 20, 2012 What is the tire pressure J owners are using for Flight Custom IIIs? I understand it is different than book. Any chance of problems putting the gear down with higher pressure? Quote Link to comment Share on other sites More sharing options...

Immelman Posted March 20, 2012 Report Share Posted March 20, 2012 Regarding nose gear pressure: The older Mooneys came with 4-ply tires. The inflation spec is 30psi. Sometime in the M20F they changed over to a 6-ply nosewheel tire. The spec'd inflation went up with that change (to somewhere in the mid 40s). So vintage mooney drivers, take a look at your nose tire: If you're running a 6 ply tire (which technically may not comply with the type certificate), you'll probably need a higher pressure to have the tire properly inflated. 1 Quote Link to comment Share on other sites More sharing options...
DaV8or Posted March 20, 2012 Report Share Posted March 20, 2012 Can't you just go by whatever it says on the tire? Quote Link to comment Share on other sites More sharing options...
