I carry two spares!
On one trip, BEFORE I replaced all my 6 china bombs with 6 Michelin XPS RIBS, I had three (3) blowouts. I show two here (1 blowout is shredded, 1 blowout with a cancer bubble, and the third blowout is still somewhere in Phoenix).

My 3 blowouts, was during the very HOT summer month of August on I-10, during the day. It was at least 104 in Tucson, and I remember it getting up to 114 degrees along the way (not counting the heat from the pavement). On the way back, I decided to drive at night!!
Since my 3 blowout trip, I’ve not had any more problems with tires since I now use XPS RIBS, and have replaced all my rubber value stems on my trailer (and Dulley Truck), with metal valve steams (I’ve since cooked the RIBs a couple of times in 105 degree summer heat – and all the tires came out very tasty).
Unfortunately, my 2 spares tires (not spare ribs) you see below are still china bombs, but if a RIB goes out, I’ll temporarily use a bomb to get to a tire dealer to order up more RIBS.
