For a B78-13 trailer tire, the closest match we will have will be a 185/80-13 like the part # AM1ST79 which is our only option in this size. I attached a review video for this tire for you to check out as well. This is a bias ply tire with a capacity of 1,710 lbs at 65 psi.

If the total weight of your pop up camper is 3,300 lbs then you would need a wheel/tire combo that at least has the capacity of 1,650 lbs. The closest tire we have to that capacity in your size is the part #AM10210 which has a 1,610 lbs at 65 psi…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…
