The bearing part # L44649 has an inner diameter of 1.063 and is typically used in 3,500 lb axle hubs and the # L44643 has an inner diameter of 1 inch and is typically used on 2,000 lb axle hubs.

If you can get me more info on your trailer like axle capacity and wheel bolt pattern I can help you pick out the components you are looking for.

@PatZ Can you let me know the axle capacity of your trailer? I wasn't able to find that and that's the info I need. I am pretty sure you have 3,500 lb axles which would be 2-3/8 inch in diameter but you'd need to verify this. If this is true the correct bearing kit would be the part # BK2-100.

The tires that were on it, P215, are actually tires meant for passenger cars so replacing them with tires meant for a trailer is a good idea. As for the size, a ST225/75R15 tire with load range of E such as the Karrier #AM10303 would be fine, though…
