I bought 4 new tires and i noticed that the rear tires have an "outside " mark on the sidewall but the front tires have an "inside" mark, Is this right ??
Tires marked with an "outside" need to have that mark facing you. "inside" marks needs to be facing the car.
If you look at the tread pattern, it is asymetrical. It looks like the manufacturer is trying to make the tire quieter, but this will only work if the part of the tread meant to be outside is actually facing outside.
It sounds like the shop that installed your tires didn't know about this and installed 2 of your tires backwards.
Did you mean that the same tire have an outside and inside mark ?? Nov 3, 2016 at 19:10
