EZE Tow surge brakes eating up the tires
A few days ago go at a stop, a coach pulled in beside us that had a dolly with the tires almost void of all the tread. A neighbor from the other side came over wanting to know about dolly vs flat tow(which I do) since he hadn't set his coach up yet.
We looked over the tires & dolly and every thing seemed fine. He had been somewhere where a guy told him he didn't really need the brakes anyway so they had been removed. Wouldn't have been my choice as a solution.
On top of that he started digging in the back of the toad and came out with another set of tires & wheels that had all the tread gone. That was his first set of tires.
The cause of the tire problem I came up with is all theory, but it makes sense.
The guy said his car was 3000#. Lets say he had another 1000# of weight in the car. Yes, he was using the car as a trailer, the rear was loaded to the roof. All that weight would be on the rear tires. As he pulled the dolly, lets say there was 1000# of weight on the dolly and 3000# of weight on the rear toad tires. Anytime the surge brakes applied pressure to the dolly wheels with 1000# of weight on them, the surge brake cylinder was getting 4000# of weight of the entire toad pressing against it. I can imagine this 4000# load could easily apply too much pressure to the brakes that only had 1000# of actual weight on the tires. It didn't appear that the tires had actually skidded on the pavement, but just had so much drag from the brakes that they just wore away very fast.
I really think it was because he used the toad as a trailer and had it so heavily loaded in the back end.
Something to think about for all those that use tow dollies and want to throw all the extra stuff in the toad to take along.
