tire size for 1998 2dr ford ranger is?
I am pretty sure it depends on the package you have on the truck...mine is the 4x4 off road and the stock tires are 31x10.50x15....you can find the stock size by googling it.I just put the size I mentioned above on my ranger about a month or two ago
Open the drivers door and on the latch pillar should be an information sticker that shows the original size tire on the vehicle from the factory
