I bought my son a 2001 Z-71. It has after market wheel's and tires that need to be replaced. He wants to go back with stock wheels.

My question is will 2002 or 2003 wheels fit the 2001?

Sorry if i have missed the section referring to this but i simply didnt see it so any help would be great...

 

It depends on how many modifications Chevy made to their tires between those years. This is something that a local dealer could easily tell you, though i do not know the answer to your question

 

What aftermarket rims/tires? Will they be the same diameter as stock?

Is the speed currently correct? Will it be off after the change?!!

Was the computer reprogrammed???
