My new Carlisle ST145R12 Radial tires for the trailer arrived on Wednesday and had them mounted.
10-ply E-Load Rated @ 1,550lbs each = overkill.
To my dismay, the right one was hitting the frame and wheel well under regular load.
After a lot of research, it turns out that the Dexter suspension is not adjustable.
The stock 4.80 Bias tire was 20.60” diameter and the new one is 21.44”.
I didnt think 4/10” on each sidebwould make a difference but they didn’t leave much space.
My only hope was that the brackets had some slop in the bolt holes to let me push them back. I noticed the left bracket was slightly different than the right.
I jacked the trailer up and put another lift under the axle and loosened the 4 bolts and was able to slide the assembly 3/16” back and that was enough to get the frame to clear the tire and both sides now have the same clearance.
It is still really tight but I think the tire pivots slightly to the rear so that will help as the back has over an inch gap.
I will check it again under full losf and compression tomorrow.
