Tire pressure

Couldn’t tell you one way or the other if it works, but it is a HDT use product.

Did you use the green slime? If it is that stuff, they say that it is self sealing also if you would ever pick up a nail. My only concern was that it would be WAY out of balance once the rig sits for a little bit. As the slime would gather at the bottom of the tire. It would smooth out eventually.

After 60 replies, did anybody ever answer the original question that I asked?

That is a very interesting way to get the proper inflation. It makes some sense to me, an engineer but I have never heard that calculation before. Just a question...what instrument do you use or is available to measure the weight on the mounted tire?

Maximum rated load capacity is at maximum rated pressure, both written on sides of tires as required by government regulations.

Why not start there and by comparing to trailer axle weight?

Thehobe1=They are scales. Available at most large truck stops for a fee.

I think hobe1 was making fun of the

Weigh your tires

comment--you don't actually weigh your tires; you weigh the camper.

Which can be done at any Cat scale like you mentioned.

F350ms, your question was answered many times on every page. But this topic, like a lot of others, usually takes in other facets of information. I, for one, think topics like this are great. Let's see; we discussed proper inflation, wheel removal, balancing, and lifting. What's the problem?

One thing that has not been mentioned is make sure when you get temp changes that you check the pressure before you go. I have pulled in a CG in the 60s and left in the 90s. Your pressure will change from that temp fluctuation. Again always cold PSI. Tires not in the sun and less then a mile driven on.

Since CAT scales came up. I just found their smartphone app, of course after my 4th trip to the scales in less then 2 weeks.

It appears with the app you can streamline your weighing, including an automatic re-weigh feature that checks to see if your re-weigh qualifies.

Should save multiple trips into the counter.

Look up www.weighmytruck.com or on the apple store search "CAT scale" or "weigh my truck"

Now that I am home for a day, this is what the Goodyear dealer used and I ended up purchasing a case of.

Port, what weights are you getting? I’ve got about 36~3700 on each wheel for my 36RSSB3, total weight with pin is ~18.3k. Per the inflation table that was provided, I should be running about 100psi in my 17.5 tires; that seems really low.

Does this weigh give the weight on each tire position or just the total weight?

those trailer people are a little toucheeeeee

Cat scales weighs the axle's: so you get more than total weight but less than each corner.

If you pull in with a toad you'd get: front axle, rear axle, and toad weight.

Hobe, the CAT scale in New Braunfels, TX has a wide apron on each side. To weigh my individual wheels, I pulled into the apron leaving one side on the scale and each wheel on individual plates.

CAT Scales at the truck stops. The 5psi is per GY Tech Support when using the inflation/weight charts.

Yes offset when going onto the scale. Tell the attendant inside your intentions before entering the scales.

Use the heaviest weight per axle to determine psi for that axle. All per GY Tech Support!

On my 36SB3 I up sized to GY "H" "17.5" tires. I used the inflation tables and ran 105psi for thousands of miles with perfect tread wear.
