i getting a 4.5 in lift what size tire should i get an should i get a 16 in rim or leave the 15in rim on lol an also would i need to get a pair of wheel spacers

 

32's or 33's with some trimming

 

i would stay with the 15's i got black steel wheels(15"x8" with 4.5BS) for $45 a rim at discount tire i believe. if you have a tire over 10" wide you want atleast 4.5" Backspacing. with my 265/70/15's (30.5/10.4/15) i had major rubbing on the lower control arms at full crank, i switched to 4.5" back spacing and the rubbing stopped. I now run 33x12.5r15s with no rubbing on the lower control arms still. also you figure with an 8" wide rim 4.5 back spacing puts the mounting point nearly centered in the rim which is nice on your wheel bearings and as far as tires go here is a good article:

this is a basic overview of the Lift, tire size combo question... I am not taking credit for the info. because it is a collaboration of multiple websites that I came across during my hunt for the perfect setup...

Tire Size - Amount of lift - Body Mod & Fender Trimming:

29x9.50, 235/75R15, 255/70R15
No lift needed - Some chance of rubbing under full articulation

29x10.50", 29x11.50"
No lift - Minor fender trimming will be needed
1"-2" of lift - Well experience some rubbing under full articulation and minor trimming may be needed

30x9.50"
No lift - most likely experience some rubbing (okay for street only)

30x10.50", 30x11.50",30x12.50"
2" lift - wider the tire trimming maybe needed

NOTE: The wider the tire the more trimming needed

31x9.50", 31x10.50"
2.5" lift - some trimming will be needed
3" lift - no trimming

31x12.50", 31x13.50", LT325/60R15
3"-4" lift - fender trimming will be needed
4.5"-5" lift - minor fender trimming

32x9.50, 32.10.50"
4"-4.5" lift - minor fender trimming

32x11.50", 32x12.50", 32x14.50"
4.5"-5" lift - trimming will be needed.

33x9.50", 33x10.50", 33x11.50"
5.5" lift - some trimming needed
6"-6.5" lift - no trimming

33x12.50"
5.5"-6" lift - Trimming will be needed

34x9.50"
6" lift min. - minor trimming

35x12.50"
8" lift - fender trimming will be needed
Note:
- This is with minimal lift needed
- With a combination of aftermarket flares or TJ flares / fender trimming will help to accommodate larger tires for full articulation. (This becomes a factors with mostly 32"+ tires)
