I have a 2013 Eyra, dual axle trailer. I check tire pressure before every trip and like to run between 42-44psi. My issue is I cannot get my tires to take air easily. Why is this? My previous boat was a 1998 Jaguar with dual axle trailer and the tires would take air no matter what the source. Air compressor, convenience store air pump, etc. My Eyra tires will only take air on a compressor with tank pressure around 100psi and if I hold my mouth right and cross my fingers. Usually, I hook to valve stem and get nothing. Nothing in, nothing out. It is never a easy, fast task. Very frustrating. The tires will never (thus far) take air from a convenience store air delivery system ($0.75 for 3-4 minutes). Am I the only one? What am I doing wrong?Thanks in advance.BassCatSC

A couple of possible issues. I have shooter wheels. The valve stems are right in the middle, in a cut-out, which makes them a bit hard to get to. I use a dual-piston Slime pump (roughly 3.0 CFM) and it has screw-on connectors. Never had a problem with that.Otherwise, you can always replace the valve stems to see if that is the issue. Not much else to go wrong.BTW the center-line stems is a good idea. Somebody had thrown a big piece of rip-rap on the ramp several years ago, and when I backed down, a tire hit it, flipped it over, and ripped the valve stem off. Since I have always avoided the two edge ramp lanes.2008 Pantera Classic2014 Mercury Pro XS 200

change out valve stems. the valve needle must be too deep in the stem for whatever reason.

Backin up tire caught the edge of the wood . It flipped caught the stem . Stem cracked. Had enough time to get pulled out. Though changed tire at ramp.2013 PANTERA 2MERCURY 200 PRO XSMINNKOTA 80LB FORTREX25 fury

my son, about 10 at the time, was going to back the boat off the trailer. I backed down and stopped and he was looking over the side of the boat and asked “what is that all about?” LOTS of bubbles. Pulled it out, found the problem, put the spare on and we went fishing. Didnt like valve stems on the outer edge of the rim after that experience…2008 Pantera Classic2014 Mercury Pro XS 200

Take the boat to the tire store and tell them your issue. They have valve cores they can change out in the matter of seconds to accommodate the pressure and length. Or you can buy a tool and do it yourself. Very easy and no down time.Valve CoresRegardless of the valve type, the valve core is the fundamental sealing device and should be snugly screwed into the valve core chamber. Valve cores come in short and long lengths, with the short length being preferred for high performance applications.Both nickel-plated and brass valve cores are available. The nickel-plated valve cores must be used in the aluminum valve stems of tire pressure monitoring sensors because using a standard brass valve core in an aluminum tire pressure sensor valve stem will experience galvanic corrosion and the brass valve core will eventually seize in the valves aluminum barrel.All valve cores feature a seal attached to a movable, spring-loaded pin that allows pressurized air to pass when inflating a tire, as well as air to escape when the pin is depressed to unseat the seal. While valve cores themselves can accept a working pressure of 300 psi, it is important to protect them from grit, sand and moisture. Grit and sand might prevent valve cores from sealing completely, and moisture can freeze in cold temperatures and defeat the seal.https://www.tirerack.com/tires/tiretech … techid=208 Pro-Tec Productswww.protecproducts.com
