So this morning I noticed that my right rear passenger tire was really low on air so I drove about 1/4 mile down to the nearest gas station to fill up on air. When I heard a loud hissing sound I knew I had a nail or screw puncture. Sadness. I take the car down to what I was told is a reputable tire shop (Les Schwab) and he told and showed me the 6" nail that poked through the tread and gouged out some bits from the sidewall. More sadness. The tiredude then tells me since I have an AWD car that I would have to replace all 4 tires. Wow are you kidding me? The other 3 tires on the car are fine with less than 12k miles on them.
So my question is, would I be ok with just replacing 2 tires or would all 4 be necessary? Cuz personally I think that's some BS. Or I could be wrong and owe the tirejockey a virtual apology.
