Im thinking about getting either top guns custumz cheapest 3in suspension lift or 2500 v10 or diesel coil springs and rear add a leafs. I was just wondering what the biggest size tire i could fit using both lift ideas. I am gonna stick with stock 3 spoke rim (16x7) until i get money to buy better ones. Thanks in advance.

 

Probably 285-75-r16 which is about a 33" tire. You might rub on your control arms using the stock rims and 285's

 

on my 99 sport i had put in the front coils from a 2500 diesel, and replaced te rear 3" blocks with the stock 2500 5" blocks plus added a leaf, total i got about 4". and i ran 35's clear and easy, just rubbed a touch at full lock turn or when articulated. might keep in back of your mind about regearing your rears to 4.10, 4.56, 4.88, depending on the trucks activities. and also a drop pitman arm, sway bar extention brackets, just to name a few.
