On I-80 and I-55 California there's a modified chain control and it only requires for singles or tandem axle drive trucks one on each side on outside Tire if you have a single axle you have to chain all 4 tires the maximum chain controls as for on a twin-screw tractor and two on a twin-screw tractor for the minimum chain control also you need to single chains on your trailer in California in Oregon they have I believe it's a a set of three rollers and a set of shingles on a twin-screw tractor and two singles on the trailer and you have to have an extra chain with just in case you break one
S SORRY, Auto maximum chain control single axle Drive tractors are not allowed over I-80 or I-5 a minimum is 3 railers on both sides of a single axle tractor and 4 singles on the outsides of each drive axle on a twin-screw tractor minimum chain on a twin-screw is single chain on one axle only on each side
Heres a couple links: https://tripcheck.com/Pages/minimum-chain-requirements.asp# http://app.leg.wa.gov/WAC/default.aspx?cite=204-24-050 In Washington, if you have a 2-axle (one drive axle), 3 railers are required on the passes. If you have a 3 axle, you can have singles on all four outside tires.
Chains are good until maybe 30 at most. Whatever speed limit is imposed by the factory that made the chain is your limitation. It has nothing to do with secret non published higher no break speeds. There is none of that. Liquid tankers will get onery if you let it. You have to be very smooth and then even more smooth in ice. Unfortunately chains will start up a harmonic which will cause your liquid to jiggle if you go too fast. Anyone can pull a hill. But it's the getting down that will kill you if you let it. Chances are, if you are on chain, conditions are so bad you should park it. That is how I saw it.
There is an app created by OOIDA called "Winter Chain Laws". I believe they have it for Android and Apple. It has all the current regulations per state for the lower 48, and links to the actual state regulations. And if the states make any changes to their regs, it gets updated.
I guess if you got inspected, you could probably be in trouble. But generally, most trucks only carry 3 pairs of singles. If they're smart. You'd be surprised how many have NONE on their truck. Speed is whatever your feeling comfortable with. Most times conditions are right you'll be driving much faster then the 25 mph you posted. If it's that bad you can't do at least 25. Then the highway will probably be shut down anyways. Easy does it on the downhill side but 1 pair on A trailer axle is usually good enough. And all that'll be required. Most of the times you're only going to need just 1 set on the tractor and can probably get by with just one chain on the trailer. Unless your on snoqualmie where drivers seem to be the laziest. Or the 84 in oregon. They don't have chain controls so you'll encounter a lot of drivers make an attempt without chains. And will end up closing the freeway down. And if you get stopped on the uphill side. You're going to have a very tough time rolling again with just one set on the tractor. Donners you can get away with just one set of singles. They have chain control and don't usually require max chains. Even though the websight will usually say max chains. Last year, i chained up more then the previous 5 years combined. Got shut down in oregon 4 times because some semi jackknifed. If you don't have to. Stay out of oregon. they use pea gravel for traction instead of salt for snow melt. You'll be visiting the glass shop on a regular basis.
