What would you say the max speed full loaded 40 ft unit on a chassis can handle?

    I checked a yard full of chassis, i noticed they all almost have the same type of tires on it, narrow and with ribs on the arch of the tires. They don't look like they are rated for more than 60 mph loaded at 80,000 gross. I did not take a note of the tire type, just passing through the yard with another driver as I will start next week with my own truck. The guy i was with said that he's blown 2 tires already in the last 3 weeks going 65 and said to stay at 60 or less.

    Drive for prime and you will not have to worry about going over 60.

    Was the tires on the tractor or the trailer.. .

    Either way the only way your going to have blown tires is if the tire pressure was too low in the first place and the tire heated up to it's failure point and came apart or exploded.

    Or the tire has been Punchured by some type of object and has lost all its air pressure.

    What kind of weight are they putting in the cans?
    40,000 pounds or is more like 120,000 pounds.

    What kind of chassis are they?
    Tandem or Tri-axles.

    What are to tires rated for when it come to speed or weight rating?
    The tires could only rated to for only 55mph and 4000 pound per tire.
    (Note 500 pounds less for the inside tires)

    I would look and check out the tire on line and It's weight and speed rating.

    Ya could be driving around with a time bomb on your hands ready to blow at any time.

    Get yourself an air gauge and an air hose with a glad-hand attachment so that you are able to inflate or deflate as necessary.

    Yes you don't really have to worry as long as they are properly inflated. I regularly run 70 with pier chassis.

    Tires were on the chassis, it's a tandem axle chassis. I did not ask him if they were properly inflated. I'll ask him next time I see him. He probably just did the kick tire method instead of sticking it. The total truck/chassis weight was just under 80,000 lbs so that means 40,000 something loaded inside the cans. Once I get started I will of course check the tires online to see what I am running with. I will definitely invest in a glad hand air line to be able to adjust the pressure on the tires.

    **EDIT** I just spoke to him, those tires are bias ply tires not radial, I did reading on the difference on those 2, bias ply has stiffer sidewalls and is constructed differently, so it will build heat quicker than radials. Are you those who says they run 70 with containers, are your tires bias ply or radial?

    75 mph all the time with properly inflated 10.00/20's, used to run Denver to Goodland, Ks. and back, empty out, 79,900 back, sunflower seeds, typically 45,500 in the can, 75 mph was no problem, usually would stop twice to check them, if anything started to get hot, would back it down to 65 mph for awhile

    And some of the rubber on those chassis leaves a lot of reason to worry.
