I am looking into purchasing new wheels and tires for my 88 ranger but cant seem to find the info on the older rangers. I currently have the stock 14x6 wheels on my 88 and am looking to purchase new 15x8 wheels and was wonder if the new wheels and tires i have been looking at would fit. 15x8 wheels with -19mm offset and 3.7 backspacing with general grabber at 2s in 255/70R15. any help would be much appreciated!!
