My tire started losing pressure and made weird sounds when driving, so I figured it has a puncture and I will to replace both rear tires, which is above $200. However, they found a nail and were able to patch the tire instead and I ended up paying around $60 in total.
Had they been dishonest and replaced the tires, I wouldn't know about it. So they were honest, polite, and reasonably priced, so they will earn my future business.
