Hey everybody!

I'm trying to create a reference table that explains what tire sizes will fit under various lifts. What I need from you all is the following information (feel free to copy template):

  • Sub-model (z71, z85, etc)
  • Tire Size (diameter, width)
  • Rim Size (diameter, width, backspace)
  • Wheel Spacers
  • Lift Height (hub to fender measurement)
  • Lift Components (i.e: 4" skyjacker, 3" body lift, 3" crank, etc)
  • Flares/Fenders (i.e: fiberglass fenders, Z71 flares, etc)
  • Trimming Requirements (valence, body mount, etc)
  • Any Rubbing (Yes / No, Where / When)
  • Pictures (If possible: side profile, other related tight clearances while turning / flexing THUMBNAILS PREFERRED!)
  • Build Thread Link
  • Other Important Details
1 post per person: but feel free to edit your previous post as needed. *If you have had multiple set-ups, include all of them in your post.

*If you are one of the Nation's YoYo's, please put each set-up in their appropriate threads

No Bullshitting: I want to keep all clutter out of this thread to make it easier for me to compile all the information and insert it into a spreadsheet. I don't want to sift through 30pgs of chit-chat. If you have any comments, questions, concerns about either the data or chart, please PM me instead of posting in the thread.

Hopefully at the end of this, we can create a reliable source for new people to see what size tires they can fit for their set up.

I have created one for the lowered folk as well. Link: http://www.355nation.net/forum/lowering/61256-post-up-your-drop-tire-wheel-set-ups-needed-data.html#post1841938

Thanks everybody for your assistance! :salute:


NOTICE: To view a spreadsheet of the given data visit the link below.
>>>Lifted Chart<<<
Please continue to provide data by posting up in this thread then we will add it to the spreadsheet.

-04 Z71 Ext Cab

-33*12.5*15

-15*8 With 4.0 backspace I believe
-no wheel spacers

-Don't have measurement

-TB crank in front, pro comp aal in rear, and 3" PA body lift

-Z71 Flares

-Trimmed A LOT including body mounts, lower valence by tow hooks, and fender wall/flares

-No more rubbing on flat ground but with any flex/turn combo rubbing occurs mainly on flares/fender wall

Idk how people say this set up can clear 33s fine with minimal cutting. But then again My truck is an 04 and TB's are probably sagging by this point.
