Normally I try to keep my drives and tandems evenly balanced. While driving in Wyoming during high winds I put extra weight on the tandems. What about on ice? Extra weight on the drives? Anybody adjust your weight distribution according to conditions?
If the road is iced over for a dozen miles: I tend to drive 45MPH-, and 30MPH- in mountains (when chains are not required).
Nearly jack-knifed 3+ times last week on I-90 in Montana/Idaho/Washington!
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".

Driving style aside, is there any advantage to adjusting the weight on the drives/tandems?

Trailer seems to handle better when evenly balanced

Always try to have the Drives slightly heavier than the tandems. When the tandems are heavier than the drives they can be a lot tougher to control. Think of it like this, you're going on a downgrade on a slippery road and you're at an angle on a curve. Well, all that weight on the trailer makes it easier to jackknife because the trailer is heavier than the drives so they can easily "get in front of you". I hope you can picture that.
What you could do to help with the wind is slide your tandems back. When the tandems are forward the rear end of the trailer tends to "whip" a lot, by sliding your tandems back you help reduce this whipping effect.

I can see that in slippery conditions having more weight on the drive would be better. Makes sense. Interesting point about the whipping effect. I hadn't considered the articulated nature of the beast. Thanks!
OK. Would you prefer more weight on the drives in dry conditions also?

You're welcome! You're the one person I helped this month!
Anyhow, you're a good guy and we haven't heard any news from you in a while. How have you been?
Been averaging 2800 miles a week. Having a good dispatcher is the key. 3 months out and I haven't had a 34 hour reset yet. He is the retread master.
