uneven tire wear
 

My trike has a single tie rod. The right front is wearing noticeably faster than the left front. i do tend to have the right brake adjusted to stop with more force because it has the parking brake lever and has to hold the bike on hills, the left. brake is the ebike cut off brake and does not have the parking lever. I'm pretty lightweight (140lb), don't ride
very fast - anything from 10mph without motor to a max of maybe 14mph with motor). i'm not in a hurry, lol. Tires are Big Ben Plus. The wear is dead center on the tread, but there's a noticeable difference in tread between the 2 tires. i've never adjusted toe-in, i assumed
it was set initially. Does it sound like that is the issue? The wear seems to be in the last month or two. If it is toe-in, can you point me to a stupid persons how-to somewhere?

If nothing else, you can swap the tires from one side to the other. Remember to keep the direction of rotation the same as it was before you swapped them.
