2006 Chevy Colorado Spare Tire Use for 6 on 5-1/2 Inch Trailer Idler Hub Assembly


Will these hubs fit a 2006 chevy Colorado wheel. I have an offroad trailer that I pulled with my jeep. I sold the jeep and want to pull it with my Colorado but I need matching hubs so I dont have to carry an extra spare tire. I know its a 3500 lb axle but I have to check bearing diameter. I just wanted to make sure the wheels will fit over the hubs. thank you.

I looked up the information on your 2006 Chevrolet Colorado Wheel, and the bolt pattern is a match and your pilot hole will fit over the outer bearing hub bore. As you mentioned, you will want to check your bearing diameter to ensure you have the right hub and confirm the axle capacity as well. The bearings that come with this hub are inner bearing # L68149 (1.378" inner diameter) and outer bearing # L44649 (1.063" inner diameter). I've attached a picture to help.

However, you will want to take a few things into consideration:

Your wheels are not intended for trailer use and trailer hubs are not designed or tested for use with car or truck wheels. So, there is more to it than simply if the wheel will bolt onto the hub that you should be aware of.

The offset of your wheel is 35mm positive, which means the tire and wheel will sit 35mm closer to the inside of the wheel well or trailer frame than a standard trailer tire and wheel. Vehicle tires are often wider than trailer tires, so you will have to make sure you have clearance on your trailer for that between the wheel and wheel wells or frame. You will also want to account for 4 inches of vertical suspension travel between tires and wheel wells if equipped.

Another thing to consider is vehicle tires are not as strong as trailer tires. The sidewall of a trailer tire is much stronger than a vehicle tire because of its function, however light truck tires are made in a similar manner and can be used on trailers even though that isn't ideal. You will want to make sure that the load rating of your spare tire is high enough for the trailer load you will be carrying.
