Stock Spare Tire on Lifted Truck??? -- Lots of Questions

As soon as I purchased my 5 lug, I bought 18" wheels and rims, then did a 3" lift. Several months have passed and the thought of the spare tire hadn't crossed my mind until today. First question is...

1. Will the stock tire still work in my case?

2. If not, should I replace it with an 18" steel rim and "small" wheel?"

2A. If so, will an 18" rim and wheel fit in the spare tire well?

2B. Will this rim work? https://www.amazon.com/5x114-3-fini...rd_wg=kHC5N&psc=1&refRID=PTJZVW8ARPYZSK949H3H

3. What other options should I consider?

Thanks.

I did this mod to put a 33" spare under my truck. I actually managed to get my 35 tucked in there but it hits the diff when the rear compresses.

 

If you were to get a flat, you're still able to use the spare. I had to do it once when I got a flat off-roading. Make sure the offsized tire isn't in the back with the solid axle or you're gonna fuck shit up. You'll have to swap a front tire to the back if you get what I'm saying.

Learned my lesson after that, just get a proper size spare that is/close to being the same size.

 

It doesn't necessarily have to be an 18" wheel. As long as the overall diameter is the same, that's all that matters. Here's a tire size calculator to mess around with.

Update -- I purchased a new 18" steel rim and bought a used tire (265/60/18) for it. Size is 31.5" and it barely fit underneath the truck. Altogether it cost me $165. Provides some peace of mind to know that I have a spare the same size as my tires.
