Trail spare tire weight reduction

[LONGJP2]

We're looking at a difference of 14lb between your heaviest and your lightest option.
That's no more than the weight of a $20 grocery store trip in the back, so 'weight savings' is going to be almost PURELY placebo effect.

It's not just the weight, it's leveraged weight off the tailgate hinges.

Which is a problem that has a solution.

It's not just the weight, it's leveraged weight off the tailgate hinges.

Once the hinges are working at maximum weight, it just is what it is.

There are no 'blurred lines' when it comes to the factory hinges.
They were designed to handle the factory/oem spare. Nothing more.

CAN you get away with oversizing? sure.
Will it last as it was intended to last? no.

ANYTHING over the weight limit is essentially going to kill the tailgate hinges, whether that be now, or 6 months from now.

The difference of 14lb is negligible, seeing that ALL options listed are over capacity of what the factory hinges were designed to operate.

Ultimately, all options will turn the factory tailgate hinges to shit.

Didn't the free 20% cost you a tire and a wheel but the bonus is you have a spare?

Not at all, I was getting the spare anyway. OP still is wanting a spare, just wants a different size to save weight..

Maybe OP could save weight by only partially inflating tire…

As someone who measures everything on my Jeep, while I measure the spare, I don't, and won't, cut corners there for weight loss.

You: "cut corners there for weight loss" . . . commendable indeed!
Me: "cut into lasagna/blue cheese for weight gain" . . . crummy indeed!

I have LT315/75R16 Mickey Thompson tires on the ground but use a Maxxis Bighorn MT-762 LT255/85R16 spare.

It weighs 52.9#, about 8# less than your current spare and lighter than all of the options listed in Post #1 except the SXS tire.

@Mr. Bills
Thank you for the suggestion on the lighter maxxis 255/85r16 forgot that one still exists. I used to run bfg km2 in 255/85r16 and they were 54 lbs.

Just one solution? Is that the same thinking that opines that one's suspension ain't shit if it isn't labeled Currie or Savvy?

There are many solutions. Simply because a particular solution may not be the preferred solution on Internet forums doesn't mean it isn't a solution.

My spare tire is mounted in a manner that puts zero weight on my tailgate hinges and the reduced weight of my narrower spare tire mounted on a narrower wheel leverages less weight off the back end than a full width spare. That may not work for you, but it works for me and for many others who thought of it long before I did.

There absolutely exists more than one solution. I for one, am glad that there are new ones being created (ex. 2 forum members that’ve designed/created their own HD hinges in recent months).

I think you assumed I was promoting the Morryde/Exogate.

I don’t carry any spare on my Jeep at the moment. After talking with some knowledgeable people on the matter, rather than designing my own solution, I’ll most likely be moving it into the tub.

Considering reducing the weight of my trail spare tire. Never had an issue with the 255/85r16 toyo mt. Just don’t want to give up the spare.
Current setup:
26 lbs Stock Moab rim 16”
61 lbs Toyo mt 255/85r16
87 lbs total

Option 1, swap spare to a AT tire
26 lbs stock Moab rim 16”
54 lbs Falken AT 255/85r16
80 lbs total. (-7lbs)

Option 2, drop to a 15” rim
18 lbs raven rim 15”
64 lbs toyo mt 33x10.5r15
82 lbs total. (-5lbs)

Option 3, drop to a 15” with a sxs tire
18 lbs raven rim 15”
48 lbs toyo sxs mt 33x9.5r15
66 lbs total. (-21 lbs)

Thoughts?

Option 4, OCD meds.

A long time ago, my CJ had 33 x 9.5 x 15 tires.
Is there not anything close to that in a 16"?

A LT 235 85 - r16 gets you about 31.8 " dia. , most 33" are not really 33" ,check what you need.

Since I am going to run a 29" tall tire, I am going to use a Mazda CX7 mini spare. That should run under 40#.
