The 5 on 5-1/2 bolt pattern is very rare nowadays. We only have that bolt pattern available in 15 inch wheels # TA37RR.

The most common bolt patterns now for 10 inch wheels will either be a 4 on 4 inch or a 5 on 4-1/2. To use either of these wheels you would have to change the hubs on your trailer. To select the correct hubs I would need to know the inner and outer bearing numbers stamped into the sides of the bearings.

The other option is to replace the axle with a new one. This would have to be done only if there are no hubs that use the bearings required by your spindles.
