Folks,
I am considering replacing the drop axle on my 5x8 CTT with a straight axle and running wheels to match my TV. The current drop axle (Dexter 3500 w/ brake flanges but no brakes) has an overhang (distance from center of spring perch to face of hub) of about 7.5". The new axle I am looking at (Dexter 3500 w/brakes) has a listed minimum overhang of 14", which seems excessive - it would put the inside of my tires about 8-9" away from the sides of the trailer.
I haven't been able to unearth an explanation of the minimum overhang requirement other than what Dexter gives: "Minimum Overhang dimensions are based on zero offset wheels and physical clearances; and are determined by suspension type, wheel and tire combination." Note that this response seems to indicate that a flat 14" minimum overhang requirement doesn't really mean anything if they don't know the wheel and tire types.
I asked Southwest Wheel the question, and they say only "Toyota rims are not approved for this axle. The center bore, offset, and capacity will cause problems."
I have done plenty of research and feel comfortable about the center bore (Toyota rims are lug centric, and I found lug nuts that fit the Toyota wheel but also fit the trailer hub studs). I can see offset being a problem if it resulted in an overhang *greater* that the allowable spec (it won't). Capacity isn't an issue at all (remember, 5x8 CTT).
So... does anyone want to tell me that there is a real reason for the minimum overhang and I will die a firey death if I just order the axle?'
'Thank you.
