FWIW, I found a "compact spare" tire in the junkyard that would fit on a stock TR3 rim (size T135D15). Much cheaper than a new tire, and fits with room to spare. I actually keep a cheap blanket rolled up and stuffed in beside it, so it can't slide around. (Blanket comes in handy to kneel on while changing a tire.) The compact spare tires are a different construction (not radial) that supposedly does not "age out" like modern steel radials do.
Of course, you should observe the conditions marked on the tire, which ISTR calls for 45 mph max and "Temporary" use only. But I've driven roughly 2 hours at 70+ mph on it and no noticeable problems.

I carry a 165HR15 spare in my pre-TS60000 TR3A -- but it has to be deflated and even then it is such a snug fit I sprinkle baby powder on each side. A strap looped thru the rim makes it possible (not easy) to pull it out. Picture me on my butt with a foot on each bumperette pulling for all I'm worth.
Fortunately - I have never had a flat in all the years I have driven that car.

Frank,
My 1957 TR3 came with 60 spoke wire wheels, I fitted 165 Michelin radials from Coker. The spare was a 48 spoke and the Michelins didn't come in a 155 size, so I got a Firestone 155 radial from Coker as it would fit in the wheel well. When I sent the wires off to Hendrix to be trued and balanced, they said they were trash, so I bought new 48 spoke wires (MWS) and had the Michelins put on them. The Firestone fits nicely in the wheel well.

Just a side note: How well a 165 fits in the early well may depend on just how the trunk floor is bent. Back when I was using a 165 in a pre-60K car, I would sometimes have to use it as a lever to pop the trunk floor upwards before I could force the tire in.
My post TS60k won't accept a 165/80-15R without forcing it in. I had a heckuva time getting it out when I bought the car. I think it's best to find a 155 for a spare.

I have a pre-ts60k, and have a T125/70D15 (from Discount Tire) fitted to an original wheel. It is marked 60PSI max, and though much smaller than a stock tire, it holds the car up. I've never had to put it on the car while on the road, but have test fit/drove with it. The tiny wheel/tire leaves enough spare space in the boot for a scissor jack, spare water pump, spare belt, spare fuel pump, spare alternator, spare distributor with cap and wires, extra flash light, fuel filter elements, misc wiring, lug wrench, towel and handy-wipes. That way I have room in the trunk for a few tools and luggage. The boot is only opened in case of emergency. -not that I plan for one.
