Triaxle: Upgrade to E Rated Tires?

[RichT]

I would stay away from the elec/hydro like the plague. I have 2 customers with them and hate towing them. Very expensive, not very smooth, and 2 systems to maintain. I would put surge disc brakes on a trailer over them or even some of the new electric drums that are approved for fresh water. Not sure if the last option will work for you seeing your local.

Interesting viewpoint. The offshore forum guys, many with triaxles that tow long distance, almost unanimously recommend EOH brakes. Surge brakes, if you ignore the clunking, is OK on level roads. Downhill is another matter and backing down the ramp with just the truck brakes stopping nearly 20K lbs is not much fun.

why not surge on 1 or 2 axles, and electric on the remaining 1 or 2, seeing as you are planning on messing with them anyway.

you might even consider going to tandem heavy duty axles instead of your current tridem if you realy want to dig into it.

I think mobile homes and lowboys use 14.5" rims, so size isn't a problem

Mixing break types is not desired. Surge brakes rely on the trailer trying to push the truck. If you put electric brakes on one axle and keep surge on the rest the electric axle will brake then not allow the surge axle to push as much. As a result it will overuse the electric axle and not use the surge axle enough and in the end probably take longer to stop.
