I currently have this setup all around: 14 x 6 steel rims with 225 70 r 14 tires. Here's what I want to do. I want to get larger wheels and tires for the rear, but I want to still be able to use my SS hubcaps. Did GM make 14 X 7 rims? And I'm not talkin' about rallye wheels, just the regular factory steel wheels. If I can get a couple 14 X 7 rims, what size tires would fit? 235 60r 14? I have stock front and rear suspension. Thanks in advance.
