I've searched for this and I seem to get stuff that helps but nothing that completly answers my questions. I have a 91 Trooper with the stock alum wheels and tires (235R15),I think they are being refered to as snowflakes. I really like the look of the stock alum wheels on the 99 and later Troopers, they look like a 5 spoke design and I think they are 16's. There is a salvage yard here with a set that I think I can pick up pretty cheap. My question is will they fit, do they have the same bolt pattern, will anything rub on the rim or tires. If they do fit what do I need to do to make the speedo correct and how will it effect my gas mileage, I know it takes a little more effort to turn the bigger tires but they also travel a little farther on each rotation.
