run flat vs spare
Howdy guys, Im really a C3 guy but have a buddy with a tire problem. He actually has an SSR. The run flats for his ride have been discontinued. He wants to stay with those but cant. SO, 1. Know where we can find some 19" AND 20" runflats? OR 2. Where can we find a spare that will work. He has 19" on front and 20" on back. Quick searches dont turn up any donut type spares in 20", but maybe a 17 or 18 might work if total overall diameter is ok. That is the question then, know what donut might work to get the correct overall diameter??

The immediate issue he will have is that the SSR's use a truck's 6 lug pattern, so my solution will require wheel adapters.
Using hub centric wheel adapters, he can purchase the Cadillac CTS mini spare which is a 18" unit.

I'd get a road-side spare kit.
In my wife's XLR-V and my C6 I keep a slime smart-spair kit
The XLR-V gets this one...
I actually keep this one in my vette since my rear tires are so much larger (345s)

Why?
You'd prefer to be on the side of the road attempting to find the puncture and then attempting to remove it, ream it out and plug it? Do you know how hard it is to do this on a vette without removing the tire (VERY hard if it's a small puncture).
I'd rather just flip a switch to fill/seal the tire at once and be much safer.

I would add: "in the night, when its raining, at the side of a busy highway with no runoff area as is standard in many cities". But, no Corvette would be out at night in the rain.
I always smile a little when people tell me they have a plug kit for a car with 5 inches of ground clearance WITH air in the non runflat tires (now down to four inches of clearance without air).

I think that one spare would do. If it matches the diamater of the rear wheels, he's okay on the rear to protect the posi-traction clutch plates, and if he puts it on the front, it will be taller, but for a short distance at lower speeds, that's okay. Ever see a tiny space saver spare on the front of a car. It works.

There is a guy that does this for the C5 & C6 crowd. He narrows a C5/C6 wheel and then uses a narrow tire. He also includes a holder that mounts to the floor, and a jack.
