 Post subject: Zero offset wheels?

Hi all, new member here so hello to all firstly!

I have a 2014 dmax on stock 17 inch alloys at the moment. I'm considering buying Raceline after market alloys, shown at the link below but am concerned about the offset being zero.
The stock wheels are +33, so my question is, does anyone have any experience with changing the offset that much? Tyre size will remain the same at 255x65x17
I've increased overall width on a BMW 330i by only 6mm per wheel and the general feeling was inferior to the stock alloys even after balancing and re-alignment.
I expect that an overall 66mm increase in track width on the Dmax is not a good idea?
Can the suspension be adjusted to compensate for the change in offset?

Link to the Raceline wheels : http://gforce4x4.co.uk/RACELINE-RAPTOR- ... _1750.html

thanks!

Just a few things to consider.
Increasing the tracking width more than 25mm, ( I think it is) makes the vehicle illegal.
The inner bearing of the front hub is designed to take the direct force/load from near to centre of the wheel. Increasing the track will load the outer bearing more than designed. Yes people do it but most, perhaps all, never report the failures or the more frequent replacement of bearings.
It loads the studs on all wheels more than before and hammers the ball joints too.
It causes bump steer to be evident because any impact to the wheel which has it"s centre outside the pivot centre of the ball joints axis means it will be felt in at the steering wheel. In offroad use it means any sudden impact often can bend the tie rods.
If ABS is activated it means the wheel will try and wrench onto outward lock on that wheel if it is the correcting wheel at that moment, not exactly what is programmed for in the ECU ABS/traction or stability control.
What advantages do the wheels you want actually provide? Are they rated to the same loading capabilities as the OE rims? if not illegal again.
Just a few facts of reality.

Balancing and realignment would have no curative effect.

Thanks for that input.
I simply wanted to improve the appearance and stance of the vehicle, but with all that you've said taken into account, I think I'll stick with the stock wheels.
The Raceline wheel load rating is 2500 for what it's worth.

I had a look at the at the wheel site, an horrendous price, and they seem to only be in 9" rim width. that means the stock tyres would likely not properly fit the rim for tyre performance reasons. ie, the tread is less than the 255 tyre carcass width would tend to have the sidewalls trying to be straight up and down. It would mean the tyres beads aren't wanting to be seated where they should be with the natural design of the tyre. Any slight curb hit or track bump would begin to scrape the rim. Most 4wd tyres do the opposite, they try and preserve the rim edge.

Yeah, very expensive ..
I thought the stock wheels were 9 inches wide, if not what width are they?

Aren't the OE rims 7" wide?

So, according to this page below the stock wheels are 7Jx17 ET33
https://www.wheel-size.com/size/isuzu/d-max/2014/

According to this page, 7J means 7 inches wide
https://www.oponeo.co.uk/tyre-article/h ... l-markings

Yet according to this, 255 tyres fit on 8.5 or 9 inch wide rims

What after market alloys are folks on here running in 17"? I can't find any in the stock 33 offset.
So, I'm not sure. This just confuses the issue even more.

Stock is definitely 7 inches wide, after doing more research. I've decided to stick with the stock alloys for now.
