I'm afraid to go on a long trip without a conventional spare. What are the options?
Small floor jack suggestions would also be welcome.
TIA.

Spare tire choices
Having just been through getting a flat with my 2013, running over some flashing (roofing) with a nail in it where the nail didn't stay in the tire, was wondering if anyone had put a "real" spare in place of the "temporary mobility kit". While the compressor with the built-in fix-a-flat got...

They have 20"
Just get an 18" wheel from a 13-19 Police Interceptor Sedan or Utility. It's a direct fit for standard SHO brakes and the diameter is almost identical to the 20" SHO tire.

"Close Enough" is not good enough for me. I want a spare with a near identical circumference as the four wheels on the car.

245/45ZR20 103Y 724 rev per mile
Not going to get much closer than that.

I was under the same rotation was necessary to avoid drive train damage. I get its not far off. Just asking is all. And thanks for the thought about the clearance of brakes and some aftermarket spare.
The tiny bit of difference in size is compensated by the front and rear differentials.
Plus, we're talking about a spare which is not going to be on the car for thousands of miles.

Another factor to think of is the 20" wont fit in the tire well and from my understanding the 18" PI wheel is narrower so as long as you use a narrow tire it should fit in the tire well with enough room for a scissor jack under it. Id say for a spare you cant go wrong with a PI wheel since they came on Taurus and Explorer you can find one easy and for far less than an aluminum wheel of any kind. like @Texas Marauder said, a small difference in rotation wont hurt especially if its only for a short time.

as for a floor jack that's up to you and your preferences, I swear by the harbor freight aluminum racing jack, cheap and low profile, light and the handle of course comes off, but it does eat some room. That with a cordless impact gun and flat tire turns into a pitstop rather than an ordeal.

So with this jack in the trunk one can only also add two dead bodies instead of three? Asking for a friend.
The two tire and wheel assemblies are virtually identical in size. Both wheels are 8 inches wide. To maintain the correct rev per mile you should use the tire size listed previously.

So why wasn't an 18" spare included with the SHO? Cost savings?
That and weight savings. The steel PI wheel and tire weigh @ 65 lbs.

depending on height and how creative you are with a bat you could still manage 3. Tell your friend I said "Eyyy"

I was misinformed, I was told the PI wheel was narrower so that it could fit in the well, my 20" flower doesnt fit in the well.
Two dead bodies and a ******....

Thats not much of a difference and in reality the tires are never truly to spec and different wear along the corners is more different than this. Its either the left or right on the front that wears faster anyway because of the torque and weight. The 18 inch rim is perfect but im sure the person who wants a full size spare wants the same exact rim to match. I just had to use my little scissor jack yesterday. They work very well imo if the road is flat i guess. I just drove to the closest tire shop when i heard the bolt clacking with every rotation. Popped the wheel off in the parking lot and rolled it in to be patched.

I do know I can buy a new SHO Police Car wheel for $165 (I believe that was the price). And then I would get a used tire and have it mounted/balanced.
I've never looked under the carpet in the trunk to see how much room was there. If there is a little bit of extra height I won't care. To me having ease of mind by having a full sized spare is worth the small loss of trunk space. I've only taken one long trip in this car (RT to Chicago, almost 2000 miles total) and was not at ease the entire time. Ain't gonna happen again.
