Utility 53’ flatbed

I bought one new and had zero issues with it. Everything held up well. 2015. Sold it 2021, next owner was happy.

How much is a new one nowadays? - mine was $30,500 back then.

 

2020 mfg running since 05/21, alu and steel frame. The mileage is around 350k, I guess. Still has factory Michelins that I'm about to replace. Not a fan of the tiremax system - wrong indication plus have to inflate the tires every 7-10 days at 95 bars. Like they're programmed to behave this way.

 

wow
95 bar is 1377.5 psi
9.5 bar is 137.75 psi
It is no wonder your tires are slowly dropping to "normal and safe" pressures.
With all the connections in a tire inflation system being pushed to the limit or beyond I would think that it is normal for the system to drop to what would be "normal" operating pressures of 7.2 bar(105 psi) or less and the tire inflation system would maintain a standard pressure.

 

Oops,I messed with the numbers. The pressure drops to 90-95 psi, not 9 bars (which is super high, for sure) Was too tired when commented here. My bad! So the pressure drops to 90-95 psi every 7-10 days.

Nope, it's just a trailer after all.

 

Most tire inflation systems are adjustable and if you use the soapy water test on all the connections and fix any leaks then you can set it to the pressure you want and it should maintain it. Always check these systems after running for a while because they will adjust for hot Air.

 

I own a trailer with the tiremaxx system. I believe it’s what it’s called. Anyway it’s amazing and I love it. Want to add it to my Mac but I didn’t even look to see if it’s compatible with the axles yet.

 

To continue here with Hedrickson axles and Tiremaxx on Utility trailers. I learned more and the system is designed to be really good. It has a range when it inflates or deflates the tires. The only problem is that it looks like it's factory set up to 90 inflate / 110(115?) deflate. And you'd need a special gauge tool or drive to a dealer to adjust it. So my factory Michelins that I'm going to replace, have been perfectly worn after almost three years. However, I just don't feel confident that 90 psi cold or 110(115) psi max would be good for other brands tires. A dozen of tire shops I called don't do adjustments of such systems.
