I’m not a car person. Drove over a nail and need to replace tire (it couldn’t be repaired). Was quoted a ridiculous price by the local mechanic who is usually honest and does a good job. Additional 50 dollars to mount it. Same price from a national company. I found the same tire on Amazon for half the price I was quoted. Is it possible to install the tire myself? I’ve never ordered a tire online. I’m guessing it has to be mounted by a mechanic. Does anyone know if this is possible? Thank you #finance
