Anyone carry a "temporary use spare" in their car?

My 2016 Mustang GT doesn't come with a spare, and this model doesn't have a spare available that fits. The fronts are 275/40/19 and with the 15" rotors, Ford doesn't have a spare to fit. The rear is a 275/40/19 and the offset wont allow the rears to swap to the front. I carry a plug kit, a compressor and green slime. I picked up a nail in the inside sidewall on the freeway last year. I tried to use the "Flat repair crap" that came in the car, but didn't know I had a hole on the sidewall. I was only able to get about 15 lbs air to get me off the freeway and stop to air again. Then I got to the gas station and filled to 25 lbs and made it to a Les Schwab. Thats when they told me I had a hole in the sidewall. $350 for a tire. Nope, fill it to 50 lbs and I went to work. Got off work and towed it home. Ordered 2 new tires off of tire rack for $296 and plugged my old tire and drove it to the install shop. So now I carry a Harbor freight Aluminum jack, breaker bar with the correct socket, plugs and the above compressor and slime. Longer trips I take the good 275/40/19 and if needed will have it mounted on my rim.
