Tire Pressures

OK.....so I put in what the tag inside the trailer recommended but geez....the ride was stiff and hard. Granted, the trailer was NOT loaded down but is there a happy medium????

Welcome to the forum!

The only way to know you have the optimum tire pressure is to get your rig weighed... at least by each axle although four corner weights are better... and then use the tire mfgr's pressure chart to determine the pressures you need.

When I picked up my new 40DP I had the same experience. I knew I needed to get it weighed but hadn't yet done it when we took off on our maiden voyage from Sacramento to Phoenix. I had the tires inflated to 110 # since that was listed on the placard in the coach. The ride was so harsh that I was afraid I had made a mistake in my purchase.

Once I got the coach weighed, I could reduce the pressures to 90# and it made all the difference in the world.

Good luck

Going by weights and charts is a good start but you can also use a more direct measure.

What tire pressure does is to keep the tire from flexing under load causing heat that stresses the tire. Monitoring the temperature of the tires with an IR thermometer when you stop for a break is a good way to minimize tire problems. If the tire runs hot (usually above 120F or so depending upon conditions) then it needs air. If it runs cool, then you might be able to get away with reducing the pressure in the tire.

Some TT tire makers specify that the tire be run at the maximum pressure. Only by contacting the manufacturer or reading the manuals will you know for sure.
