Alright so I've been looking around to find a full size spare and finally found something. But heres the catch, I bought a set of (4) DC-1's that have (I believe) 3 7/8ths in. Will it hurt if the backspacing is different on the spare?

 

no, unless you plan on running it for an extended period of time.. one side will stick out more, what you dont want is different sizes side to side.

 

What does that mean? Like one side with 2 wheels that have 4" BS and one side with 2 wheels at 3.5" BS?

 

You don't want different height tires side to side. Especially if you have limited slip. The different backspacing won't hurt.

 

no i mean you dont want different diameters. 33 in one corner 35s on the other 3 corners..

with 4" bs on 3 corners and 3.25 in one corner should be alright, just dont pretend your in a Ferrari.

 

You'll be fine with a spare that has different backspacing, as long as the tire is the same size like they said above me.

If you don't know your back spacing just grab a ruler and measure it.

 

Thanks Guys
