3" lift /17x9 0r x8/ 275 tires

ok well my lift will be here soon so gotta get tires and rims.
i was looking and the backspacing and stuff confused me.
what bs should i be looking for?
do i need new lug nuts?
should i go 17x8 or 17x9?
are 275 tires less likely to rub and do they look bad with 3'' of lift like 265's?

oh and im gunna throw this Q in...will the tsb aal lift the back to 3"

pics are welcome to give me some ideas of rims and tires
thanx

 

I went with 17 x 9 with 4.5" offset with 265 x70R17 and 3" toy lift and they scrub every now and then when backing up and turning hard.
So if you want the bigger tires i suggest the 17 x 8

 

I agree with Jhodge.

 

ok so a 17x8 rim will rub less?
thanx for ur help guys

 

I have 17X9 MM 951's with 265/70 17s. The offset is -12 and they don't rub at all with the Toytec Ultimate lift with the coilovers set at 3.
