18s or 20s

Yeah I was really surprised they required that much trimming. I do think it makes a difference MT vs AT. I take it off-road at least once a month and I do flex the suspension to its max while at full lock.

BTW did you measure the width of your BFG ATs? I am just curious what the difference is. It seems like people installing BFG AT 285/65/18 do not have a problem (very minor rubbing), but other tires (especially MTs) require trimming.

no but i can go check it out now...

whats your MT width?

 

[Zed 71]

I will check mine when I get home too. I recall it is 11.2X". Very close to the theoretical 11.22" (285 mm).

I'm a little curious how my 285/70-17s are going to fit when flexing offroad. I don't do much offroading so I'm not going to worry about trimming anything yet. Normal driving, even at all lock and pulling up the slope up into my driveway I don't have any rubbing....but I have yet to check the sway bar as mentioned in a separate thread....

 

[UofMZ71]

yeah 2ELO i havent checked the sway bars either! ha oh well, guess ill be looking this weekend. i would like to take the truck off road but just really havent found the opportunity.

im measuring from side wall to side wall and getting about 11.25 or maybe a tad more, BUT i also have the tires at just under 40psi as i hated the DIC telling me i had the tires too inflated at 48 psi and dont want to spend $200 to reprogram!

Hmm....I dont want to have to trim that much, may just have to stick with the 285's. That still gives me an extra 20 mm over stock tires. I think if i just go with the 20x9s instead of 20x10s it'll give me the exact same look, tire on the rim. Prolly try to match stock offset/backspacing so they wont stick out at all.

yeah that seems like a good plan, im not a big fan of tires that stick out, but the one good thing about the Z71s are the fender flares so having a bigger and wider tire doesnt seem as awkward... not that any of the other trucks here look bad! just not my taste...
