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
  • Drop Height (hub to fender measurement)
  • Drop Components (i.e: 2" Blocks, 3" DJM Arms, Stock ZQ8, etc)
  • Flares/Fenders (i.e: fiberglass fenders, Z71 flares, Xtreme 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 lifted folk as well. Link: http://www.355nation.net/forum/lifting/61254-post-up-your-lift-tire-wheel-set-ups-needed-data.html#post1841924

Thanks everybody for your assistance! :salute:


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