Widest 15" Wheel and Tire combo on the rear? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1BadSS · 03-01-2007, 10:14 PM

I have a stock 71 rear suspension on the back of my 69. What would the maximum wheel and tire size for the rear, in a 15" size.

I don't want to tub the truck or move suspension.

Hey you have to wait for some of us to get home from that four letter word - WORK
I have 18.5" tires under the rear of my truck. I had to put slightly wider tubs and trim the edge of the bed a small amount. Wheels have a heavy negative offset, I do not remember the offset, let me know if you want it.

I have 15X10's with 5 inch backspacing and a 345/55 drag radial on my 72 LWB.

Sorry I was busy working on my truck. If you aren't trying to keep those tires inside the fenders and the truck is at near stock height, theoretically there is no limit to the width you can go with ala you don't go with more than about 5" backspacing. You going for the tires sticking way out the side drag truck look or what?
