Do yourself a favor and go to walmart or even pick a part and make sure you have a jack, lug wrench and serviceable spare... Flats seem to have a way of picking the worst possible time and waiting 3 hours for roadside assistance is no fun at the best of times...
That is my advice anyway - it comes from long experience...
I drove past a guy the other day sitting on shoulder in his Subie with space saver spare leaning against vehicle.....stopped and asked if he wanted help as I carry a HF "racing" jack, cordless impact, flip sockets and even M12 inflator with fully charged 6.0 in each of my three trucks
Subie guy says he's been waiting 2 hours for AAA and they just updated him saying "any minute now". Ok says I, enjoy your day!
I drove S into New Mexico to run some errands, stopped in the Safeway to pay too much for Starbucks (my vice), went to the pawn shop, Harbor Freight, etc etc
Come back past him 2.5 hours later and he's still sitting there. "Sure ya don't want help now?" says I. I made it clear I don't need money or fame, it just sucks he's sitting there for such a simple reason.
This time he accepts. Checked his spare first thing -- yep -- ~12psi. Got that filling with the M12 inflator, dug out my jack and cordless impact....by the time car was elevated and wheel off the spare was nearly 60psi. Waited to hit 60, threw it on, snugged lugs with impact and warned him they're not properly torqued but if anything too tight and will get him the ~20 miles to town.
4.5 hours wait time for 4.5 minutes of actual work.....crazy
