Trailer Tire/Wheel Combo for a Karavan Snowmobile Trailer with 8 Inch Wheels and Hydraulic Brakes

Question:

Can you tell me if this rim will fit my 2004 Karavan 18foot Snowmobile trailer with dual axles and hydraulic drum brakes. I have tried Dexstar 8inch rims and they will not fit around the brake drum. The OEM rims have a smooth inner surface where as the Dexstar has a ridge that narrows the rim just enough to not fit. Karavan has provided me with drawings of the axle and drum assemblies. The rim/tire they offer is only painted with a C tire and I would prefer galvanized with a D. Any help is appreciated.

There are currently no brake assemblies that are going to fit an 8 inch wheel because of the exact problem you have encountered: the hubs are too large to fit. The smallest we can go is for 10 inch wheels. You might be able to go to a 205/65-10 tire which would be about 2 inches taller than the 215/60-8 tire and wheel # AM3H325 that you have referenced. You would need at least 1 inch of clearance above the existing tire for the larger size.

If you have the space on the trailer for the taller size then you can use tire and wheel combo # AM3H440. It comes with a galvanized wheel and its rated for 1330 pounds at 70 psi. It is a D load range and it will take drum # 8-271-7UC3 for 2,000 pound axles (measures 7x1-3/4 inches) or # T1540500CB042 for 2,200 pound axles (measures 8-1/2x2-1/4 inches).
