What backspacing should I use for a D60 and 14 bolt ???

I want to order my wheels today and am unsure what
backspacing I need on MRT's bead locks,,15x12's
What does everyone here run?????

I believe I have 4.75" on 16.5" x 10" wheels with 36 x 14.5" swampers.

I think 4.5" is pretty common number. Less backspacing = less grinding on the calipers but you have probably already been through that.

I am running 3 1/2" BS on my 15x12 beadlocks, but 3/4 ton. Have a good 5 or so inches out from the fender with 17x40 Hawgs. Not sure if this helped or not.

My main concern is the rotor/caliper clearance,,,

I have already ground down the calipers for the 15x10's.

will a 15x12 mean more grinding or is the backspacing
what causes the calipers to need clearance,,,MRT only
lists up to 4" backspace on their beadlocks,,my 15x10's have 4 1/2"

will a 4" give me more or less room at the caliper ???

Confused,,,,

The lower the number the less you need to grind. The bigger the number the more you need to grind.

You need to grind more for a 4" BS rim to fit then a 3" BS rim.
