I checked the air pressure in my tires today, normally do it once a month so I never come across any major surpriises, until today. I used my craftsmen air guage, and the first three tires read 32psi, normal. My last tire reads.... 16psi. I find this pretty much impossible, the tire appears just as the others, and feels just as bit as full as the others. At first I thought my digital gauge was starting to fail. Went back and checked the first three tires and all read 32, while the last consisently reads 16. I decided to fill up the tire in question 10 more psi and see how it went. The tire was starting to bulge a bit, and was rock hard, and read 26psi, supposdly. I firmly believe I have full 32psi pressure in the tire, but the valve stem is partially blocked, or somehow giving a bad reading. Has anyone here experienced such a thing? I am going to check it the next few days to see if it remains at 16, make sure there isen't a slow leak. Above all I don't want to fill it to a supposed 32, where if the reading is really 16psi off would be actually 48psi, and the tire is only rated for 44 max. Thanks for any experience you guys can lend.
