- Bumper support what? The bumper does not support the tire. The tailgate combined with the rubber bumpers support the tire.
- With a 35 hanging off with a spacer, on the stock mount, and I assume it is not making contact with the rubber bumpers, you are asking for trouble with the tailgate and spare mount.
- You need a new bumper with a spare tire carrier.
