Tire replacement
My wife asked me to buy brown tires, but it has been very difficult to find with the same size. Her bike has 26 x 1.75 tires but the best I could find is 650 x 35A, which I think is 26 x 1 3/8. I don't even know what that means. How do you translate 1 3/8 to a decimal number and are the tires compatible with the wheel where the 26 x 1.75 are currently?
Thanks
