easy/cheap solution, drill through rear door and bolt on jeep/fj/montero rear spare mount, something like this: Spare Tire Carrier, Tail Gate Mount, Jeep Wrangler YJ & TJ, 87-06, 007460

The door is not sheetmetel, if it can hold a ladder with a person standing on it, it can hold a wheel+tire.
Bet you won't
Please send us photos of your installation (on the day of, and six months after carrying a tire on there)
You guys are funny

I'd be interested in the end results of this but against all my engineering, design, fabrication, the laws of physics, logic, and common sense please dont try this ...
but if you do try it i would advise that you not concentrate all the weight load on those 4 bolt holes but figure out a way to spread the weight and brace the sheet metal and bracket with a reinforcement on the inside of the door that doesnt allow the weight of the wheel and tire to pull on the outer sheet metal ...
and please take pictures and give a report on how it works out ...

Or get the same year Prado door imported and bolt it up. They had a substructure with a tire carrier built into the sheetmetal.
In the markets that offered the Prado 120 with the spare on the rear door there were problems with the rear door sagging and the sheet metal tearing near the hinges. I believe Toyota had a rear door replacement TSB but not sure which markets it applied to. I wouldn't put a tire back there.
Especially a larger heavier tire than stock would be problematic. Maybe a WGW Incognito rear tire carrier will be coming our way to provide an option.
OR...just get a sweet rear bumper with a tire carrier 
Ok it's a little extreme for most, but it channels my inner Mad Max tendencies!
On a serious note, I know a rear bumper is the way I will go when it's time. Wish they all didn't cost around 2k though haha
Would be awesome if someone would make a "weld your own kit" at a discounted price...
I REALLY like the rack on the blue Prado with the "Mad Max" tire carrier. Anyone know the brand?

I do NOT recommend hanging the weight of even on oem spare off the rear door as it sits. I've already done the leg work and can tell you emphatically that it will simply not support it. Hell, I had to develop a bracket that stiffens the rear door panel just to attach a heim joint to it on a already fully supported swingarm.
By all means though, use a generic jeep product on your Lexus and tell me how it goes. Id be interested to see the carnage after just a couple of weeks of daily driving it.

Well sounds like you guys actually know what you are talking about. My Montero has rear door mounted spare and that thing is strong enough for 35"+ stock. I have even stood on the rear-door ladder with the door not closed and it still works fine.

no doubt it is strong but it was engineered to work that way too ya know ... i would be very surprised if the tire carrier was hanging on the outer skin of the rear door alone ... that door skin is not very thick
Couldn't you just order the internal support brackets and insert those inside the existing door. You may need a thicker epoxy, some bolts and a couple mods. I would bet it would work.

The doors are quite a bit different. Check the exterior--there is a tire shape built into the spare-style door. Also note the position of the wiper motor on both--also completely different. The non-spare door, the motor is just about dead-center. On the spare type, the wiper motor is offset to the left-side.
I would wager one could not simply just get the internal supports (if they are even available separate from the door shell) and have them just bolt it right in. Perhaps (again, if the internal supports are available separately) you could do some custom work and get it to work, but once you get that involved, you're gonna start getting up there in cost....up where you may as well have just imported a rear door, or built/bought a custom exterior tire carrier.

and that "wheel shape " shape that is stamped in the door also adds lots of strength to the metal
