Spare tire for C5
I don't have runflats on my 02. I was thinking of just just getting a junkyard front tire and rim. If I found one in between my rear and front height any reason why this shouldn't work, just to drive her home?

Yes, it would "work", providing you limp it home. The AH/traction control would need to be turned off as the difference in side may trigger it.
I don't have runflats either, my spare tire is a cell phone. It weighs less and looks better than driving around with a full wheel and tire in the back.

Hi nuck -
The problem will be the offset and clearance of the large brakes on the C5.
The best way to go is to contact Cleveland pick a part and purchase a late model GTO spare - it has the correct offset and will clear the brakes.
I have one that I take on road trips just in case.
You'll pay around $75, and that is for the wheel and tire combo.
best regards -

Ever thought of a small air compressor (powered via cig lighter outlet), a pair of needle nose pliers, a flash light and a tire plug kit? They will all fit in your small trunk comparment and cost less than lugging a spare around. Might give it a try.

The other issue is the different OD of the tire/wheel which might damage a rear axle...

. I would keep it at home. Waiting for the auto club can be 3 hours. I would sooner get the car home on my own. When I said a junkyard tire I meant one from a C5 so there would be no brake clearance issues.The plug kit is a really good idea in addition to my spare. I will look into that.

I also have a GTO spare that I picked up for my C5. My car has the ZO-6 tires and wheels on it and the diameter of the GTO spare is the same as the front tire and slightly smaller than the rear.

IF the spare tire is not close enough in diameter to your rear tire, the positraction will actuate and could burn out your positraction differential clutches.
Runflats, designed for C5s and work great. Non-runflats, you take your chances. BTW, flat bedding a C5 with a flat tire is not a damage free experience!

If you plan on using a plug kit, make sure your jack will fit under a C5 with a flat tire. Trying to plug a flat tire while on a C5 is next to impossible, especially with the rear tires.

So, if you carry a spare tire, do you also carry a jack that fits under your car? Does it fit in rear compartment spaces?
I understand the worry over a flat, but the danger of a big tire sliding forward through the cockpit when you stomp on the brakes to avoid the jerk that just cut you off outweighs the wait time for a tow truck. How about that jack handle coming through the back of your seat? Anything in the back of the vehicle needs to be secured, well, or you risk having it crash around inside if you get into an accident.
(I just saw a Mythbusters on this.)
I switched from run flats to non-RFs and bought a small compressor and plug kit. You can also get a can of fix-a-flat or tire slime. Might mess up your Tire Pressure Sensor on that tire, but you saved more than the cost of a TPS by getting non-RF tires. I also have AAA.
