Need help buying 16x8 wheel not sure on offset

hello everyone this is my first post and i did search but nobody talks about offset.
Im looking to get 16x8 soft8 steel wheels and i know i need 4" or 3.75" back space but what about offset? I fount 3.75 back space with -19 offset would that stick out like crazy passed fenders? I will get 4" lift but i jist want my wheels not to stickout too much. I also see 16x7 with 0 offset and 4" back space but im confused now and not sure what to get.

My wheels are metric sizes (and slightly different size to yours) but that won't make much difference to your deciding to switch to a -12mm offset. I run 17" Fuel Beasts with a -12mm offset. That's the maximum offset I'm allowed to run here in New South Wales (ie. a maximum offset for both wheels combined of 25mm or 1"). I've had them on the car with a 2" lift for a year now and use the vehicle around town and off-road.
Handling? It handles like a tractor - but I've got a lot of iron work plus winch up front!

Appearance? I'm really pleased with it - the tires protrude beyond the body-line by about 1" to 1.5" either side and I've fitted a set of ebay special flares, front and back, to make it legal. Check the before and after pics.

backspace is WMS to back bead of the tire and offset is the WMS to centerline of the rim. taking either of these you can measure how far to the outside of WMS the wheel will stick and then you can approximate the tire bulge on top of that. as for on the vehicle that will take someone with one to tell ya or straight edges and measuring

Urgh, don't miss that at all

The 3.75" backspaced wheels will sit further in, but I think the Factory backspacing is ~4-4.5 so you should be OK. Not sure how you can have 4" backspacing and 0 offset on a 7" wide rim? I would think the offset would need to be 12 or the wheel 8". (no expert here).

Factory backspacing is 6" for the 16x7" wheel or 6.25" for the 17x7.5". The larger the backspacing the more from the hub the wheel sits inward.

A 4" backspacing sits 2 inches wider than a 6" backspacing.

I am running 16x8" Jegs D windows with a 4" backspacing and -12 offset. They stick out for sure but i dont think it looks too wild and still tucks into the fender well at flex. I can post a pic later if it helps. Link: https://www.jegs.com/i/JEGS/555/681032/10002/-1

Good article here to help you decide.

So i just ordered 16x7 with 0 offset, i don't have a lift yet , once i get them here i will throw one on to see how it looks and decide on the tire size and if i need a lift. Anybody know if original tpms sensors can work with steel wheels?

SO here it is 16x7 with 0 offset, just perfect almost flushed with the body. Looks like i will need a lift after all, you guys think 255 70 16 will hit fenders without the lift? Will 2" bb lift work with 255 or 265 70? or i need 4" lift for that?
Thanks

Offset measures to the bead seat.

Backspacing measures to the outer edge of the wheel.

The bead seat area is 1/2" thick.

Thanks for posting the pics. Does anyone know if running the stock 245/70 tire on this wheel spec works as a daily driver without issue?

All depends on how much clearance you have between the tire and fender, thats my problem right now i dont know how much tire travels up on big bumps, im going with 2" bb lift to be safe and 255 70 16 tire, even tho stock height looks like there is plenty of room i been told by them wheel manufacturer that i should get a lift.

I purchased 16X8 0-offset from Rough Country. I put on BFG KO2 32s ( 265/75 R16) . I have 4" lift and still had to trim my from bumper, otherwise won't fit. Rear bumper no problem. If you went with same size as mine, 2" BB then you should be fine with minimal trimming. Attached the pics so you can see. WIth 255 /70 16, i dont believe you need a lift for that. Its only half inch taller than stock.
