Spare Tire mount on rear bumper, yes/no??

[Danielflading]

I bought a spare tire mount for my rear bumper, but with all of the discussions about cracked welds and broken rear bumpers I am now wondering if I should put the spare tire in the truck or TT instead of haging it on the rear and having potential problems with the bumper failing.

Has anyone had a bumper fail due to a spare tire being mounted on it?
225x75x15 is my tire size.

thanks.

your post is what got me thinking about not using it, I don't want a cracked weld, but then again I will never have a bike mount installed so hopefully only a spare tire will not cause any damage.

I had removed the bike rack some time ago and everything was ok. I removed the bike rack because the bikes rubbed against the rear window frame doing some damage and the rack itself began to fall apart. There was no damage to the bumper at that point. This cracked weld happened when only the tire rack was attached to the bumper.

the physics involved with a bike rack, extending away from the trailer, are different than a spare tire tucked right against the trailer. the bike setup resembles a fulcrum that with the bikes bouncing, held out from the mounting point, will cause a bumper to fail way before a spare tire.

are you talking about a spare tire for your trailer or TV?

I am talking about a spare tire for my TT, i bought the clamp on style holder that uses "U" bolts to attach to the square bumper.

Thanks for the response.

considering how many TTs have a bumper mounted spare, i think you'll be fine but be sure to keep an eye on the welds.
i have my spare on the rear bumper.

i only relate my experience , the choice is yours but I was one of those who said that the bumper can hold bikes and tires as long as it is secured firmly. I have retracted that statement and now believe the bumper is merely a sewer hose holder. nuff said.

What surprises me is that my TT does not have a spare tire or a tire holder. It is a dealer model with elec brakes w/ breakaway, LP bottles, etc. I am thinking the previous owner must had either removed the spare and carrier or it was delivered from FR without the option. You would think that all TT would have a spare included as standard......

nope, most TT manufacturers list a spare tire as an option.
