Tire Pressure Question

Good evening!  Have searched the forum to read up on correct tire pressure.  It seems like the best way to determine tire pressure is based on weight etc.

How about tire pressure for dummies?  For those of you with similar coaches, what tire pressure do you run?  Any recommendations on accurate easy to read tire pressure gauges?

Thanks, take care.

I recommend you search the forum, use the search window and enter a couple of related words.  Lots if discussions on tire pressures.

Otherwise, most of us will tell you to be sure the tires are great condition and age, weigh the coach and each axle, go to tire manufacturer and read the weight table to get the proper psi per tire.  Example, my front axle comes in at 13,000 lbs or 6,500 lbs per tire.  I go to the Michelin chart and see I need to be around 110 psi each tire.

I have bought several tire pressure gauges, both digital and dial and naturally none agree. There is a good article on RV Tire Safety about gauges and how to check them.  I like the gauge he recommends. about $12 from Amazon. Since it is very hard to get a checked against a calibrated gauge; he suggest to buy two or three and compare them then keep one as you master gauge.

Roy,

Good site to bookmark. I also have had tire gauges that did not agree. Had a HF tire gauge from China that was too long and damaged the valve core resulting in a leak. I had to use a metal valve cap to seal the leak until I could stop at the next town to buy replacements.

We just returned from a three week Thanksgiving trip California to Detroit and back. When we left, I went to a gas station and noticed all tires were down. Filled to 44 PSI and then discovered several days later that they were at 55 PSI cold. Service station gauges are not to be trusted.

As a rule of thumb if you don't know individual wheel weights look at the plate by the drivers seat and inflate to the recommended pressure for a fully laden coach (GVWR).  Ride may be a little hard but you won't be running under inflated which is the worse thing you can do.

As for tire gages have always used Milton brand both professionally and personally.  Worst thing is dropping them BTW.

I don't see which gauge you are seeing on Amazon.  This is the one I use.  Works well, matches my digital gauge and is with in a pound or two of my TPMS.  Less than $15.  Clips on the valve stem so you can inflate or deflate without holding it on the stem.

Here is the gauge I use.

Bought two and very close to my other digital gauge.

My rule for Tire Pressure For Dummies is from my Truck Tire Dealer. His recommendation after 40 years in the business is "run maximum pressure according to what's on the tire". Catastrophic blowouts are most often caused by low tire pressure not high pressure.

I personally run 100 psi at 70 degrees F in all tires. My coach is usually loaded to near capacity.
