What pressure should my tires REALLY be at?

I am a newbie pulling a Rockwood 8310SS, with a dry weight of 7200 LBS. The tires state a MAX PSI of 50. I was concerned about inflating to 50, especially when the TT is loaded, as the fear of a blowout at 100kph (60 mph) freaks me out. The tires do look a little low and the gauge indicates they are at 44-46 LBS each. Should I bring them to 50 before I hit the road? What is right?

Thanks

top up to max PSI on tire, so 50 psi cold

Agreed!
There is more than enough built in allowance for air expansion.

Hello, I used my stock tires for a year than upgraded to some Goodyear. There are many horror stories on here with blowouts etc. Just make sure you keep an eye on pressure and more so the loading. Tow level as to not put strain on the back axle towing high.

Hope to make it out west in a couple summers and enjoy your part of Canada.

Definitely inflate your rear tires on your tow vehicle to the Max pressure, cold, as indicated by the information on the side of the tire. This also pertains to your trailer tires, Max pressure, cold, regardless of how loaded it is. Especially if they are not load range "E". I would also bump the front tires of the tow vehicle up 10 Lbs over usual.

The primary reason for blowouts on tow vehicles and trailers is LOW pressure, not high pressure. When a tire is under-inflated their is more "rolling resistance" between the tire tread and pavement and this increases the tire temperature which then leads to tread separation or side wall failure and a blow out. So MAX pressure when towing.

Another thing, when you replace your tow vehicles and trailer tires, always buy "E" load tires. These are ten ply tires and will provide extra protection against blowouts and pots holes. I just returned from a 5K mile trip back and forth across the US. Have load range "E" tires on both my PU and 35 ft. 5th Wheel. Before we left I inflated the rear tires on the truck and all 4 tires on the trailer to 80lbs. We hit some of the worse roads I have ever encountered back East with huge pot holes, many of which could not be avoided. I was sure, on several occasions, that the truck or trailer tires where going to definitely blow as hard as we hit the pot holes. Never had one single tires issue during the entire trip. Load range "E" tires are definitely worth the additional safety and the little extra price for the piece of mind they provide.

I maintain 110psi in my Goodyear 614's, which is the maximum sidewall pressure cold. When traveling, my TPMS will show an increase up to at times 128 psi. How much over the maximum sidewall pressure cold before getting concerned?
