I'm looking for some wheels for my 98 4wd 4drblazer. I plan on lowering my truck 2-3"andwant to go with a 20" rim all around and I would like to know what is the max width I could fit front and rear? What offset would it require and? What backspacing would it require? Would it be possible to fit 20x8 front and 20x10 rear wrapped in 245/35 front and 255/30rear?

 

i know the 20x8 w/ 245-35 will fit and the rear should fit too, im not too good w/ the backspacing
