I have used both the alloys and steel 3rd generation rims on my 98 Dodge. The steel rims if used with matching newer hubcaps fit but the newer hubcaps are too shallow to use, so I went for the 17" alloys. The steel would only work on our truck with the older caps. The alloy wheels and newer caps bolted right on without any modifcation and look sharp. They are thicker than the steel wheels and set the hubcap out a little farther from the rear axle enought to fit. I run now a set off a 2007 with stock Michelins and luckily bought them for $300 for the new take offs! Two tires are worth more than that. I tried some 16" alloys off a 2002 and they won't fit over our rear brake drum assembly so stay with 17". If you ever want wide 17" alloy wheels, look at H2 Hummer wheels. I think they're 10" wide and for sure 17" size. I have a friend that runs them on his 1999 dodge diesel and they are nice! You can find them on Craigslist. The Portland site now has a set of four for $200. I thought of buying them for snow tire wheels. The centers need opened up a bit to fit the rear axles as the axle hole is a slight smaller. He did his with a hand grinder of all things and looks okay. He then used Dodge hubcaps to finish the look. If I get a chance, I'll look to see the width stamped on my alloy rims and email you this info unless somebody else clues you in here. You'll like the alloys. good luck. Herb
