Quick ? on wheel offsets and tire sizes

i know yall get tired of answering these stupid questions. ive looked and looked but most threads are for 18s or 17s

anyway, i have a 3" lift on the way, and im about to order my tires and wheels tonight. im going to run 275/60-20 Cooper Zeon LTZ's with 20x9 KMC badlands chrome

now its a 33" tire with a 20 on a 3" lift. the wheel width is 9". they only offer a -12mm offset (4.53" BS) or a +18mm offset (5.71" BS) im assuming that the -12 would be better since its closer to 0 offset.

im sure i will have to remove mud flaps and trim some plastic, thats fine. but what about clearance around the UCA Body Mount and frame?

sorry this seems like an everyday thing. but im going out of town tomorrow and want to have them ordered and on there way while im gone

thanks guys!

 

-12mm offset (4.53" BS)...you covered everything else as far as trimming and all that junk...good luck bro and post up some pics asap!

 

so the -12mm offset will work fine? thats good to know. i love those wheels and i found a deal on themfor like 1,100 shipped. thats 300+ cheaper than anywhere else. i will for sure get some pics up ASAP! i would post it up nw, but shes just all stock and mighty sad looking

but shes about to get a facelift! so pics ill follow soon
