Rhino-Rack Spare Tire Bike Rack, 2 Bike Carrier

This item has a width of 24 inches. Most likely it will be too small for a 33" tire.

If the camera is in the middle of the tire, the frame itself will not block it. When the bike support bar is folded down (i.e. not in use), it comes close to the middle of the tire, so you should see it in the camera view. In any case, when you have bikes loaded, they will probably block the camera too.

i cant say for sure if the frame itself would be wide enough to sit down on the tire like it should. the strap that's on it may not be long enough either. i had mine mounted to a 32" tire and if i remember correctly the strap just was long enough to go around the tire with maybe a couple of inches left to pull on to tighten it.

this will not fit your tire size
