Going "Prime"time

I have a question is there really a diffrence on the super singl axels vs the douuble

 

Yeah 1 has 1 tire and the other has 2 tires. LOL The super singles are not as good in snow. Also if you blow a tire you are stranded unless you chain the axel up. Be very cautious if you do this. Depending on your load you may put to much weight on the opposite tire. Dont try this on the drives.

 

Well, I'll disagree. I think wide singles are just as good in the snow, although as you start approaching minimum tread I think they get a bit more slippery than duals. I ran through a number of situations last winter that had the guys with duals sitting beside the road STUCK, that I just ran on through on my singles. Upslope to a loading dock on fresh snow over packed snow, empty trailer: The guys with duals had to chain-up to get in - I just backed right in, no jewelry.

I heard an interview with a fella who had the opportunity to run comparisons on Michelin's test track - same GVW, same equipment... just different tire sets. The wide singles would break loose in a controlled manner, but duals would break loose unpredictably. Curved track, smooth concrete flooded with water. After running wide singles for the last year and a half, I can say they are just as safe, perform just as well in winter and you get the superior fuel economy (assuming you actually do have a low rolling resistance tire) that wide singles provide.

Blown tires. If you maintain your tires properly - and by that I definitely mean never running on low air, make sure anything that gets picked up in them is removed and avoid road hazards, you shouldn't have a problem with blowouts. OTOH, its illegal to limp down the road on a blown or flat dual tire. That'll get you 30 CSA points, put out of service and a cheery visit with safety. Either way you wait just as long for road service with duals or singles.

 

Aperently the DOT has a different view on running with a flat. You can do so (I looked it up in the reg's). It is recomended that you go no faster than 45 MPH. Prime might have a company rule that you can't, more than likely because of running supersingles. I even had a azchp escort me to a truck stop, because he said it was much safer to get it off the freeway and get it fixed than do the repair on the side of the freeway.

 

Ah, really? Not trying to be a jerk, but if that's your idea of what the bears are looking for, I think you need to do a little refresher...

392.7 Equipment Inspection and Use

No commercial vehicle shall be driven unless the driver is satisfied that the following parts and accessories are in good working order, nor shall any driver fail to use or make use of such parts when and as needed.

snip... glossing over other minor stuff like brakes...

Tires.

Just a wild guess, but I'm kinda leaning towards "flat" isn't part of the definition of "good working order." Also, the CVSA Out of Service Criteria mentions for steer tires specifically and all other tires in general...

Tire has noticeable (e.g. can be heard or felt) leak, or has fifty (50)
percent or less of the maximum inflation pressure marked on the tire​

sidewall. (393.75(a)(3))


That's what they go by when inspecting your truck - and its "Out of Service Criteria." My guess is "flat" is mostly likely 50% or less of the maximum inflation pressure! LOL!

Also, 393.75 (a) specifically states...

No motor vehicle shall be operated on any tire that... (3) is flat or has an audible leak...

Sorry pal... the AZ CHP cut you some slack. You can't run a flat at any speed. Its not Prime, its the LAW!

 

Well I can see you have much more experience that me. I only have 20+ years of otr and you ? What If we go by you we only get flats at the end of the day so that you can find them when you do your inspection. NOT. That is just 1 of probably 25 or more times I did this. I have gone thrue scales with a flat. I just got on the CB and as I entered the scale I told them of my intentions and that there was a repair shop at the next exit and I was giving the green light. Maybe you should go tell all the DOT scales your story. Like I have said in the past newbies just beware of info on here that is from newbies to newbies. They will get you killed.

 

Ip are you looking at the little book for the regs you get at the truck stop or that Prime give you, if so get the big book from keller. It goes into detail as the little green book is just the basics.
