New here and already got a quick question!

[21792jeep]

Hey fellas, and ladies? I am new to the jeep world. I just got a 1991 jeep cherokee. Traded my 1994 saturn and 300 bux for it. For now I just want a 3" lift and some nice wheels and tires. I was wondering what the deal is on backspacing and such with these big tires and small rims. I am used to 18" wheels with low pro tires on my baby(Eagle Talon). Anyways, I am getting a set of 31"X10.5 tires. I am wanting the cragar 15x7 black wheels. It says they only come in a 4", 5", and 5.5" backspace. Will I be okay to go with the 4" backspace with 31x10.5 tires and a 3" lift?

Let me know please,

Anthony
