Today I ran over a nail and since the puncture is so close to the side wall I need to purchase a new tire (My truck and tires have 6,000 miles on them) however when I was inspecting the other tires I noticed that they all have (in different locations) a slight (but very pronounced) indent that you only really notice when you run your hand around the sidewall of the tire.
Now I read on here that this is a result of the manufacturing process however some tires have 1 indent and some have 2 also the spare that was up under the truck has several very pronounced indents (that are very obvious just from looking at it) as a result of being pushed up against the frame of the truck so tightly at the factory. (I checked the tires on the other trucks at my house and none of them seem to have these indents on their tires)
Do I need to replace these tires because of the indents in the sidewall? I'm getting ready to go on a 16,000 mile road trip; I checked on the Dunlop website and they said these tires were good for 60,000 miles (which I highly doubt) but figured they'd be at least good till I got back from my trip. Now I'm not so sure. Does anyone have any advice?
