Hey y'all!
 

Hey so I'm new just dropping in to say hello and let you all know that I've got a 2011 Dodge Nitro! Also am in need of some help! My nitro just got the wheels changed and since it happened I've had an odd rubbing noise when in 4 wheel drive! However it's on the front side of the nitro on the wheel they didn't touch! Any help would be appreciated if anyone might know what is going on! Right after it happened I had an exclamation point near my 4WD light! Please help!

Welcome. Moving to the Nitro section. Need to verify you have the correct backspacing and offset on your new wheels. Take it back to the installer. You didn't pay them to screw up your car....

So they're telling me now that my tires tread is making the binding noise and only way to to it is get two more tires of equal tread depth and tread type!?

Are all four tires the same size, according to the numbers?

If you have different size tiers then yes, 4wd requires all 4 tires to be the same size.

Yes all 4 wheels are 245/50R20's however two are Pirelli Scorpions and the front 2 are Goodyear wranglers! I don't know I'm just confused why it's making this noise after I put new wheels on it

Whats confusing is your confusion about the term wheel and tire. Tire is the rubber part. Wheel is the metal/aluminum part. What is rubbing? Tires or wheels? Why did you get the wheels changed to begin with? What wheels did you put on? Stock? Aftermarket? What are the wheel specs compared to the stock specs?
