Cobra Trailer Spare Tire mount failure

I have that option, I put a plate on the inside of the trailer to help carry the load. The real problem with the initial installment is the bolts are too short and it is a real tussle to get the wheel off the bolts because as soon as one or two are loose the tire shifts against the remaining bolt and this can cause the threads to be damaged. Additionally, it is almost impossible to get the flat tire back on the bolts because of weight and short bolts. BUT, better than having the tire break off the original mount and fall on the nose of the glider.
