Backspacing to fit under guards

[GR_76ers_Iverson_3]

Hey guys,
I am looking at getting some BFG km2 muddies this year and trying to work out the backspacing I will need on the new rims.
I have a 2.5 inch lift,
Looking at the 33x10.5-15
And the rims I have found have a 3.75" backspace on a 15x8 rim.
Would this combo keep the tyres under the stock flares? Or marginally stick out?

With that combo the tires will stick out past the flares, you will need 6 inch flares

I have the same size combination & they major stuck out. 6" wide flairs don`t quite cover them, but way more legal looking than stock. I think you can get a 7" wide set that looks like mega wide OE Jeep flairs. Maybe these would suit you?

I had 15x8 3.75 bs with 6 inch warn flares and 33x 10.5 bfg muddies and the tires were flush with the flares,before that the 12.5 wide tires stuck out nearly an inch

Sorry anotherblacktj, I miss-read the first post. I`m running 33x12.5R 15 tyres.
Cheers,
