4.0" backspace on n/t?

[thomastenn]

anyone running 4" bjs made 1 hell of a offer for me on some 16x8 rims just want to make sure i wont have rubbing issues with 34x10.5 tires with 6" lift

On a 15" rim, that is almost touching according to my eyeball micrometer so on a 16" rim you should be ok. You could always run a 1/4 wheel space if you have to.

Don't know if it helps you out, but I was running 3.75" of backspacing on a 15x8 wheel, 32x11.5 tires on a 4" lift... no rub.

4" will rub on 15s. Not sure about 16s, but even with those, your'e getting real close to the tierod.
