1st Gen aftermarket wheels? help needed

I apologize in advance because I feel like I should've been able to find this info on my own, but after lots of trying, I cannot.

I have a 2002 TRD 4x4 SR5 ext cab with 6-lug 16" alloy stock wheels, stock height (no lift). I would like to swap those out for satin/matte black wheels, and if possible I would like to widen the stance just a little bit (nothing too crazy, just want a slightly more aggressive look). Just an inch or more.

Best I can tell, I have a 16x7 rim with 6x139.7 lug pattern, but I have no idea about backspacing or offset. FYI I'm running Duratracs 265/75/16

Can anyone tell me exactly what I should be looking at? I like the AR Baja, but I'm having a hard time understanding the wheel specs and don't want to order something that doesn't fit. Duratrcas don't rub now, but I'm worried they might if I'm not careful about what I choose.

THANK YOU

 

see if you local wheel store has a 16x8 0 offset wheel to try. you correct on the lug pattern(also referred to as 6x5.5) if I remember correctly that is a 16x7 inch wheel it will be stamped in the inside of the wheel somewhere. the offset will more than likely will not be. if the factory has a +18 offset just off the top of my head you should have approx. a 2" over track width. im doing this in my head so it may be off just a bit.

 

Thanks, sorry, forgot to update. I went ahead and bought five of these since they're on sale for 20% off and no tax. They're backordered so I'll have to wait a few weeks but there's no hurry. They look great on the truck pictured, and that's the exact same truck I have--same color and everything.

They're 16x8 so that'll already widen the stance by 1/2" (if backspacing/offset was the same). The rims are -12mm offset which, on an 8" rim, is 4" backspacing. I believe the stock 16x7 alloy wheels I have are +12 offset, aka 4.5" backspacing.

All that is to say I should see my tires/wheels stick out an extra inch or so, each. Which is just what I was going for, nothing too extreme. Even if my calculations are off, the pictures at the link are proof that they'll fit and look good.

 

Sounds about right
