We are going to be loading 3 bikes on the back rack, 1 24" kids BMX and 2 28" adult mountain bikes. It looks like the main grunt of the weight is kept to the frame side of the bumper via the brackets and pins, has this been your observation BigT? It says it can hold 250 lbs plus the tire, so I am wondering if I can still leave the tire on with the 75lbs (guesstimated) of bikes and be ok. There has been a lot of talk about removing the spare regardless.
