14" tires are not hard to find online. They don't stock them at local stores because they don't sell them or stock them. They are busy making money on soccer moms daily cars and jacked up 4x4's

Go to Walmart, good prices and free shipping.
Don't go to the tire rack or discount tire online. Too expensive.
Not entirely true:
I've done extensive research & shopping for tires. There's hardly a difference with all these online tire stores. I bought a set of 4 205/65R15 winter tires earlier this year, and believe or not Tire Rack had the best deal, was there cheaper ones? Yes, but they were horribly reviewed, the ones I got were rated #2 in their category. It's all a balancing act for me, to me prices do matter but it's on the bottom of the list.
You are correct about Walmart as they do have closeout specials on some tires (even after filtering out trailer tires) vs. Discount tires, but not all of them will have these specials.
But even Tire Rack will sometime have online specials, I bought a set of 4 General Altimax Arctic 12 205/65R15's for $85 a piece vs. $111 normal priced.
A good example are these same exact Milestar tires:
Yes, I am extremely picky on tires, I will not buy crappy cheap tires. I've had several cheap Chinese branded tires before that had failed on me, one of them quite catastrophically. The Triangle brand I had failed only after about 10,000 miles due to the sidewall plies separating, luckily it didn't blow but I still had to replace the tires, they replaced them by pairs and it's cool that I got two free replacements. But the Westlakes I had on my old Accord blew apart on I-80 about 30 miles away from Evanston, WY. the tires were only 2 years old. I narrowly missed hitting a Semi because having your front tire blow at 80 mph is enough to cause certain involuntary soiling of your undergarments. That was also fun putting on the spare on the side of the road while having cars and semi's zoom past you at 70-80+ mph. Big thanks to WY State Patrol trooper watching over me as I changed out the tires, awesome people. (Yes I had to take one of the rear tires and put it up front due to the donut spare being a different size).
The only non-Chinese tire I had failed on me was a Continental E rated tire that was on a POS 02' GM K3500 Crewcab it was a GOV that me and my team drove to and from Camp Grafton, ND and SLC, Utah. (with driving GOV's alone I probably got a total of 500K to 600K driving miles under my belt)
Bottom line is, I don't like cheaping out on tires and brakes but I'm also not going to spend on $300+ a piece on tires that are over rated. Again it's all a balancing act to me. If you're just going a short distance and not really driving that much, then going cheap and quick is fine.

And yes Tire Rack has free shipping as well.
