Check to see if Oregon's legal weight isn't 12,000 lbs.? It doesn't matter what your tires are rated for if the state limit is lower, you have to go by the lowest weight limit..
Never mind . . . I just got the same question again and it was the 600 lbs per inch of tread with 6 inch tread width that was the determining factor . . . duh!

I mean 10 inch tire tread width . Double DUH!
That's why you gotta read those question very carefully...Brett designed the program to make you have to pay very close attention to the details...because guess what...that's attention to detail will come in very handy on the road.. glad you were able to figure it out..
There's a lot to know about that stuff, eh? I'm really glad you're doing the Weight & Balance portion of our High Road Training Program. Most people skip that section and the Logbook section because they aren't covered on the CDL permit exam. But they're going to be in a world of hurt when they get out there running solo someday and realize nobody ever really taught them:
- The Bridge Law
- How to find Length and Weight restrictions by state
- How to calculate fuel burn-off
- How to calculate weight distribution of your fuel based upon fuel tank location relative to your steer and drive axles
- How to get your axle weights legal
- How moving the trailer tandems affects weight distribution
- How moving the 5th wheel affects weight distribution
- How to calculate the number of holes to slide the trailer tandems based on axle weights and the distance between the holes
- How to determine the maximum legal length and axle weights for a group of states you're travelling through
- How to properly load cargo for balanced axle weights
- The "leverage effect" of loading cargo behind the trailer tandems
- How to use tire width and maximum tire load to calculate the maximum legal weight for any given axle
...and a whole bunch more. You obviously won't remember the formulas by heart but you will understand all of the various calculations and considerations that are involved in getting your wheelbase and axle weights legal from coast to coast. Then it's easy to look them up when you need em.
I can't tell you how many people I've talked to over the years that were turned loose to run solo and never learned even 10% of this stuff. They get out there and realize they need a lot of help. They can't get their axle weights legal, they don't know how to load cargo properly, and they have no idea what the "kingpin to trailer tandem length" has to do with anything.
Stick with it! You're going to be sooooo glad you took the time to learn that stuff. You'll need it every day of your life out there.
A CDL is required to drive any of the following vehicles:
A written or electronic record of a driver's duty status which must be maintained at all times. The driver records the amount of time spent driving, on-duty not driving, in the sleeper berth, or off duty. The enforcement of the Hours Of Service Rules (HOS) are based upon the entries put in a driver's logbook.
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

When a violation by either a driver or company is confirmed, an out-of-service order removes either the driver or the vehicle from the roadway until the violation is corrected.
Thanks for the feed back, both of you. I hate feeling dumb, especially on tests . . . but it is worth it to get a handle on all of this stuff . . . this really is a very thorough instruction/testing module . . . worth the time to go through all of it . . . I've seen several people say they did real well on the actual test because they completed this training . . . thanks again for making this resource available AND free!

I am in the "Weight & Balance" section of the CDL quizzes and I have been "Halted" twice for missing the same question - but I didn't miss it. The question is about front axel weight in Oregon on tires rated at 6,150 lbs. Now 2 x 6,150 is 12,300 as far as I can tell but the "correct" answer according to the dialogue (in the section that shows what you got wrong) is 12,000 - not the 12,300 that I have marked both times. What's up with that? Just thought I'd point that out.
