315/70/R17 Spare Too Heavy for Gate?

Still trying to get my spare mounted. I have 315/70/R17s on my stock Willys wheels. I read in the owners manual that the rear gate is rated up to 86 pounds (if I recall, somewhere in that neighborhood. I'm looking at the Teraflex HD hinged tire carrier but that's turning out to be a pretty penny. Not really looking to go with a bumper tire carrier either... I think it looks to bulky.

Basically, am I good to mount this tire on a stock tailgate or should I invest in something a little more stout? Any other suggestions out there or any other ideas?

Thanks in advance!

-Joel

I think you are on the bubble on whether or not the stock carrier will support the weight of your spare tire. Driving habits will play a big part on whether it can support the weight or not too. Off road driving may shorten the life of the stock tire carrier. It is important to ensure your tire bump stops are up against the spare tire to minimize any road vibrations. And periodically inspect the tire carrier for fractures and check the tailgate for popped rivets. You will read stories about how the stock carrier has held up fine and then there are the horror stories where the entire wheel came off the back of the Jeep.

I personally run the TF HD tire carrier and wheel mount with my 315/70/17 wheel setup. I say run it on the stock carrier for awhile but be prepared to upgrade if needed. The weight of a 315/70/17 set will vary depending on tire & wheel manufacturer.

You should bite the bullet and get the Teraflex Hinge, I threw one on last Saturday for good reason. My tailgate started to wobble after about 4 months of having a 315 duratrac stuck to it. That was after reinforcing it a bit as well. With it installed the tailgate is stout again.

Being you are not looking for a complete bumper tire carrier, the TF tire carrier system is worth evey penny. So as the saying goes " buy once cry once ". You will be happy you did.

One of the reasons I bit the bullet and just ordered the Extreme Terrain Barricade rear bumper with swing out carrier. While I have 33's right now, I'll probably switch to something heavier when the tread wears out on the 33's.

But the TF hinged carrier. There are two options, one being about $200 cheaper iirc and will max out at a 35" tire. The more expensive one will allow up to a 37" tire and has parts so you can add additional items to the hinge like fuel carriers etc.

Your stock carrier won't last long so replace it sooner rather than later.

I bit the bullet and just bought the Teraflex Hinged Tire carrier from Amazon, hope to have it by Thursday, didn't want to take a risk with the additional weight of a 35 in.

Smittybilt and Rugged Ridge are releasing their version of the Teraflex carried this month. You can see both of them on 4wheelparts.com

Smittybilt is only $499 and Rugged Ridge $599. Both come with the third brake light extension. Teraflex doesnt. With the light Teraflex is between 710-800 depending on where you buy it.

It's a huge saving but I still chose to go with the Teraflex kit because it is time tested and known to be a solid product.

teraflex kit comes with third brake light bracket for the 2 empty lug holes in the tire. Ordered the Teraflex kit today from extreme terrain, when I get around to putting it on I'll post some pics on my build thread.

Good move, it always best to wait for a new release to be out in the wild at least a year so all the issues/kinks can be worked out.

It was a tough decision but it came down to me knowing that the Teraflex fits/lines up perfectly and is reliable. So far it is holding my 37x12.50 perfectly.

Wow the Rugged Ridge and especially the Smittybilt versions are way cheaper than the Teraflex hinge and carrier. I know the TF has been out and tested but still. The RR one with its huge logo does not look as good as the other two though.

This won't work, right? http://www.amazon.com/Teraflex-48381...Tire+Mount+Kit

I would need the whole system, like this? Amazon.com: Teraflex 4838150 HD Hinged Carrier Kit: Automotive

Why even sell the item at the top link? Seems like it's pointless without the hinge. Makes it confusing.

Top one gives you the ability to mount a larger tire on a 'new rear bracket that is adjustable' but does not replace the hinges on the tailgate, so it you stayed like 31" or 33" but went wider the top mount would give you the ability to hang the larger tire width and relocate the third brake light. The added weight of a 35"+ tire makes you lean towards the bottom link, which is what I ordered yesterday... It's got impressive reviews everywhere and got it for cheaper than it is listed on Amazon from xtryan at extreme terrain.

I have 315x75x18, and our stock carrier held up just fine carrying it for the time it did. The tailgate did not fare so well... it has small cracks all over it, which I can only assume are from that tire flexing it all the time. Our tires themselves are 74#, on an aftermarket rim that I don't know the weight of, though. As someone already mentioned, it will depend on weight. We ended up getting a steel bumper with tire carrier, and life is better now.

I wouldn't put anything over stock tires on the rear gate from personal experience.

From what I've seen: will work out just fine for a while... Then it won't!

Seems like most people get a couple years before trouble. I wouldn't run more than 12 months.

Teraflex bracket, carrier, and extended brake light holding a 37x12.50r17. Tire should be tight/squeezed to the carrier in back.

I don't know if its a time thing or a "hit the ride bump in the road" kind of thing. I know it starts with one weld and thus starts flexing more and more.

Exactly, hence suggesting replacement before.

Joel,

If you put something in place to hold up on the weight of the tire (something that goes int he receiver maybe) and also make sure the tire is tight against the tailgate, you might by a little more time. I've seen people running 33's like that for a while without issue.

A 35" tire is a lot even for that set up, but it'll by you a little more time. If you decide to go with the Teraflex Carrier or a Bumper with a carrier, let me know and I'll get you a great price!

Cancel order and go through Northridge. Use wranglerforum discount. $599 for both hinge and carrier.
