Mixin wheel sizes

Using the word staggered always makes me think about different diameter front to rear wheels and not different widths.

Anyone ever mix, say, 20"s in the rear and 18-19"s in the front? Pics?

It can definitely be done. Obviously it hurts your ability to rotate tires, but overall its no different than running a taller tire in back. Just be careful not to stagger more than 1.5" or so, or you loose ABS.

Off the top of my head I couldn't remember any Impalas set up this way, but I know that new Vipers have 19" wheels in the back and 18" wheels in front.

Can't rotate tires runnin different ("staggered") but same diameter either. Not a big issue if the stance is right.

That's where I'm at right now with suspension/wheel decisions.

Gonna install extended rear arms (and driveshaft if necessary)

Gotta figure out desired ride height then spring choice to get the fender height right with the widest (non-tubbed) rear tire width and staggered (both width and diameter) wheels that'll run as close to the fender lip as possible without hitting the fender.

The Caprice with the Z06 wheels is 18 front 19 rear isn't it? I like that car and look a lot. (I think his name is Mike?)

There's a few threads around on the subject. I ran 20/22's on my wagon when I had it, and the current owner is running 22/24's.

I've seen the 18/20 combo on someone's car here... I bet I could dig it up with a search. And I'll do that for Gene since he's helped me before, instead of saying "Go do a search!"

Back in a few.

You's a funny dude! Post up pics of your car mane! You got one of the tightest 'staggered' joints on here...24/22 IROCS on that DCM lowered to hell.

Based on some numbers I ran on stock GM setups while evaluating ABS reluctors, the ABS computer should tolerate up to + or - 5% total wheel/tire diameter mismatch and not throw a code. This is purely a paper analysis, so take it for what it's worth.

Kurt, what size tires do you have pictured there? Extended arms? Springs? Cut or not?

Gene-

That is my best friends old car, from one of the links that I posted earlier, it was sometime ago and not exactly sure on the sizes of tires, but 18X8.5 in the front with 255/45/18's and 20X10's in the rear with 285/30's Sorry I can't remember it has been about 5 or 6 years now since he had them on there.

Springs are Hotchkis, Hotchkis extended arms, nothing was cut.
