I’m making some final decisions on tire size for my project 6 and would appreciate some help.

I would like those who run front 60s or 44s to post tire size and front diff ground clearance. Those with 30 fronts are welcome to post as well. Thanks in advance for your time.  

I'll start

44-33"-10 1/4"

Some companies have a list of advertised and actual tire size. Talking to the guys at Pitbull they mentioned their 37” are not 37” but their 39.5 are pretty close to spot on.  

http://pitbulltires.com/downloads/PBSPEC2.pdf

I have a good idea on some brands and can factor those figures in but asking the members to measure the height and check air pressure is out of the question. It’s not an exact science I’m trying to get a rough idea.

Nav, post up!

and the D-25 is included as well.  Cheesy
