How do you thump your tires?

HI DR, "zero outside", ha, haven't thought of that in a while ( it's like 97 on the east coast now) That's a good question. At zero, I'd think the tire may be a little low, so I'd check it once the tire warmed up some.

 

I put this right up there with truckers that claim to be ex Navy Seals.

I check air pressure with an accurate gauge at least once a week and thump tires at least once a day, more frequently in hot weather. My method of thumping is to wear leather gloves and slap each tire, holding my hand to the tire after the slap to feel the vibration. I'm no ex Navy Seal, but using this slap method I've been able to detect more than a few tires that needed air. If I suspect a low tire I break out the gauge for a better reading and if it is low bring out the 50' air hose.

 

I ask that because I would load in Dallas and deliver in Cheyenne and it was way too cold to check the tires....lol!​

 

I'll vouch for the cat-eye devices. Makes checking tires WAY easier. Well worth the $100/axle. Also makes it way easier to top off, which is a major god-send in say... a blizzard.

 

^^^^^THIS^^^^^^

Enough said.

 

I punch the sidewalls with a gloved fist. If you have a nicer newer trailer with matching tires they will all thump the same. Old crumby trailer with 4 different tires it's a little harder to tell. I use a gauge if one is giving me an ambiguous thump.

 

It is easy to figure PSI with a thumper. First you need to strike the tire at a 45 degree angle and at a rate of 50 pounds of pressure. Then you figure recoil of the thumper pressure and add 18 then divide this by 2 and add 20 and that is the PSI of the tire. However, if you want the old fashion way just get a tire gauge!

 

And as someone that runs out of Phoenix with the most extreme temperature conditions, that leaves when it's 105 to 110 ( in the shade ), and drives all through the mountains and regularly goes to SLC & Denver, my tires are tortured.
100 psi all the way around, your always good.

 

Wrong wrong wrong !!! If you're gonna try to spread info on the interwebz you better AT LEAST get it right!!!! Everyone knows you MULTIPLY by 2!!! Divide?!!! Sheesh. Blasphemous

 

Next time you get fuel check the tires with a gauge and if need be look for an air hose near by.But many places now charge to use their air like a dollar for so many minutes.Here both Loves and Pilot charges.
