depends on what look you want, if you want it clean and tucked on the rear wheels 5.5 backspacing. If you want a more aggressive look than go with a 4.5" hope this helps some The 15x8 with a 5.5 b.s. look flatter additionally 15x8 wheels with 4.5 b.s. have more of a deep dish look. The 15x3.5 only come with one size as far as backspacing goes. The biggest you can go on the rears would be 275/50/15 to a 275/60/15

15x8 with 4.5 backspacing on a 275/60/15 Nitto drag tire, you'll have to roll your inner fender but that's it. It's a big tire 28" tall.

Here's a comparo of my old 265/50-15 and my 275/60-15 tire. Big difference!

You want it to fit inside the fender, you need the 5.5 backspacing. The 4.5 has the deep look but it might let the tires touch the fender over a hard bump.

Although I think the 5.5 b.s. looks cleaner with a 275/50 tire you will have rubbing issues on the inside and will have to bang the insides in a bit where ever it may be rubbing, additionally you will still have to roll the inner fender to keep it from cutting the tire up. My boy is running that combo on his LX and it rubs on normal turns and whatnot.
