Look at Eastern Marine the 10 x 2 1/4 are on sale for $26.00. It take about 1/2 hour per backer plate to install. While off another 1/2 hour to clean and pack the bearings, most dealer will do that they will just pack them dirty in 5 mins. If the bearings are packed right you need new seals about $5.00 from a supply house or $15.00 from a shop.
Tires and balancing depending on what you buy.
The important thing is to jack up the trailer when completed and rock the wheel while holding at the top and bottom. You should feel a slight movement. No movement they are TOO TIGHT and you will burn a bearing.
