Outer Limits 4x4 Board

Gday,

Im about to order a set of black 15x7 Dynamic Sunrasias for my 03 Hilux. I run 31 x 10.5 MTZ tyres. A few questions re offsets:

What offset rim do i need?

Will a -19 offset stick outside of the guards more than a zero offset or the other way around?

Cheers for any advice.

-19 will mean the wheel sticks 19mm further outside the guard than a 0 offset rim would. I think the IFS hiluxes use 0 offset stock.
This explains offset:

Addit to above...

You cannot just specify offsets, you need to give the rim width to work out how much backspace the rim will have when fitted up.

One other thing to be aware of is clearance to disc calipers and rotor. Some rims fit better than others.
