I cannot tell you how much I LOVE these guys. Seriously. I have been coming to OK Tire in Airdrie as long as I can remember. They were recommended to me by W&B Automotive, when I bought my very first car and I needed Winter Tires. Don was extremely accommodating. Every time I have a flat and need a tire repair, they've always gotten me in right away and gotten it fixed immediately. Sometimes at no-charge even!
My most recent experience was today. On Saturday I got a flat tire in Madden, AB and had to get AMA to come change my tire. I tried to get into Canadian Tire to have them fix it, and they told me the hole was "Too big for the plug" and that I needed to buy a new tire. And they were going to charge me a fortune for it because I have 17" low-profile tires.
I took it in to Don this morning and he had a look at it and was able to fix it.
I ALWAYS recommend OK tire to my friends and colleagues when they ask me where a good place to buy tires is. Even if they live in Calgary, the quality of service is well worth it.
