Very cool. What about the G8? It might have come with a spare? I know the 04-06 GTO’s did but I’m not sure they are large enough for what you need?

The base model G8 that had the V6 engine came with a spare tire and jack kit. The GT and GXP models did NOT come with a spare tire or jack kit. Instead they came with a 12 volt air compressor and a can of tire puncture sealant.

When I took delivery of my 2009 G8 GT in 2009 I talked to a engineer at GM about the spare and we made arrangements to have the spare tire in the trunk of a base model G8 installed on a GT. It fit on both the front and rear. The only concern was using the spare on the rear with the limited slip axle. Note: The limited slip axle was not available on base model G8’s. So if you had a flat tire on the rear of your GT/GXP you may have to put the smaller diameter spare on the front and take the front tire and put it on the rear.

I then found out about a dealer who was selling jack kits for less than dealer cost. I figured the dealer must have been buying the kit directly from the supplier. So I ordered a kit from the dealer. I then ordered the steel space saver wheel from GM parts using my GM employee discount. The hard part was buying the actual space saver tire. It came from a supplier in China and there were none in the US and none on order. Eventually I talked to the right person at GM Parts and he said he had a few other calls about the tire and that he would place an order for 50.
