Greetings - I currently use a Matrx Elite DEEP 16x16 on my beater chair. I just got a set of knobby tires that rub on the bottom corners of the backrest... not so much that it greatly interferes but enough that it will destroy the backrest after not too long. I *think* the reason for the rubbing is due to the depth of the backrest - pretty sure the standard depth would be out of the way of the tires. I use this chair strictly for things like camping and other off-road (freewheel-required) adventures, mostly as a means to get from point A to point B and then transfer or sit still. It's generally not a comfortable ride in general so it doesn't have to be perfect. All that is to say that going with something not as deep and/or slightly wider (I don't think I can go down to the 12" high though) would probably be sufficient. I also need/want to stick with the Matrx so that I don't have to mess with replacing the mounting brackets and can switch back to my current 16x16 DEEP backrest when I'm running my regular tires.
Anyone have any thoughts and/or possibly something for sale that would fit?
Thanks,
