ewacowboy Posted August 28, 2016 Report Share Posted August 28, 2016 Tired of reaching between the wheels to check my air pressure on the rear duals. Anyone have any suggestions on a valve extension for the inner tires that won't fail in a few thousand miles?? The rims are solid aluminum and the center caps are one piece bolted on with the lug nuts.

Alie&Jim's Carrilite Posted August 28, 2016 Report Share Posted August 28, 2016 Do you currently have "Semi" style all metal valve stems? I say semi style to separate what a HDT 22.5 or 24.5 rim size type uses vs what a 19.5 may use. Our valve stems are all metal, no rubber anywhere except the O-ring that seals the hole in the rim. I have seen valve stems that are brass with the rubber grommet that seals the hole. These will leak with any side force applied to them.

ewacowboy Posted August 28, 2016 Author Report Share Posted August 28, 2016 Yes, they're all metal 22.5s. Just wondering if anyone has used the straight extenders vs the braided extenders that tend to flop all over the place. Any experiences are appreciated!

Pat & Pete Posted August 28, 2016 Report Share Posted August 28, 2016 Not on a Freightliner , but on our Monaco : 6 years ago I had a similar problem , as one of the braided extenders that had been on the rig for who knows how long took a walk to a wheel owned by someone else , not by my choice . Anyway , I ordered a new set of braided extenders as a replacement and installed one in the 'open' location . Real dumb of me to think that those braided extenders would last . I'm still waiting for any of them to fail in any form . Sure I have to top off the pressures occasionally , but , from what I've read , that has to be done with any combination of valves and/or extenders . And , those braided extenders have never flopped around at all , let alone all over the place . Goes around , comes around . Link to comment Share on other sites More sharing options...
CrazyCooter Posted August 29, 2016 Report Share Posted August 29, 2016 These guys have a pretty good selection of extended stems. http://www.shinyrv.com/store/c26/Dually_Valve_Stems_.html 1999 Peterbilt 385 C12 430/1650 13spd 2006 Dodge 3500 DRW 4x4 2010 Hitchhiker Champagne 36 LKRSB Link to comment Share on other sites More sharing options...
Grassy Posted August 29, 2016 Report Share Posted August 29, 2016 I use the straight extenders. I had one fail over the winter storage last winter. From the look of it, it was probably original to the truck when purchased new. I replaced my tires, etc this spring and put new extenders on. 6K miles so far and no issue. Will add TMPS units when we head south. . Arctic Fox 29-5T . Beagle co-pilots - Faffy and Lulu Link to comment Share on other sites More sharing options...
SuiteSuccess Posted September 1, 2016 Report Share Posted September 1, 2016 Any valve extenders need rubber or wire supports otherwise they can vibrate and leak or fracture. The link above for shiny RV sells the supports. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.
