I'm looking to change the original Nivalis alloys on my Scout with something else; I was never a big fan of the 5 spokes/star-ish design, I prefer 7+ spokes designs in general.

I'm happy to keep 17s as I prefer a softer ride and don't mind some light off detours on outback tracks every now and then, but will increase the channel to 7.5.

I realised most of the OEM VAG wheels are pretty much interchangeable as stud diameter (112) and bore (57.1) are the same - so anything with ET40 to 50 should fit with no issues. 

 

My concern is the inside part of the rims - I found there are 2 different design/patterns around the bore and studs.

 

My current Nivalis have some sort of trapezoidal spacing as per the picture:

 

Some of the Audi and VW rims I like have instead circles:

 

Can either be fitted without modifying anything? More in general, is there anything else I should consider other than stud/bore/channel?

Just make sure you clean up the corrosion from both the wheel and brake disc mating face and torque to 120/140nm whichever your is. You want to get the et correct really or might have to fit spacers.

If going for different offset go for a smaller number. A higher number will push the wheel towards the suspension particularly if going for a wider rim.

So no problem with either of the inner designs (trapezoids vs circles?) are they fully interchangeable?

Yep, with 7.5 channel I'll have:

ET 45: around .75cm extra each side of the rim (current nivalis are ET45 but 7inches wide)

ET 40 to 45: most of the extra rim surface on the external side. I'd prefer this actually, I think the wheel arches would look a little fuller - especially the back ones.

Just to double check. You currently have 40 and going to 45? With half inch wider rim? That would make it 17.5mm closer to the suspension. Not something I would risk.

No, I have 45 now. I think keeping 45 on a 7.5 shouldn't be an issue:

 

 

 

Anything 40 to 45 would also fit easily I think, and make it appear slightly larger:

 

Yeah 6.5mm closer to the running gear from a starting point point of a narrow rim should be fine.  45 to 40 should be fine.

If you get rubbing, it's not the rim that rubs but the outside of the tyre.

 

Fitting a 225/50R17 to a 7.5J rim instead of a 7J rim will increase the inflated tyre's width by about 6mm, ie. 3mm each side.

 

Fitting a 225/50R17 to a 7.5J rim width instead of a 7J rim width will make the ride slightly harder, and provide a little less protection from kerbing damage.

 

Outside width of inflated tyre (measured from the outside of one sidewall to the outside of the other sidewall, at the widest point)

225/50R17 fitted to 7J rim 233mm

225/50R17 fitted to 7.5J rim 239mm

 

How much the sidewalls bulge out each side from the rim

225/50R17 fitted to a 7J rim 15.6mm

225/50R17 fitted to a 7.5J rim 12.25mm

Can try not share the wheel tyre comparison site? Im looking to change from 205/55/16 to 235/35/19 thanks.

That's awesome info, thank you!

 

Doing some research I found out that Scout3 facelift do actually come out with 7.5 ET45. (Scout FL was NOT imported in Australia, hence I didn't find much before really looking into it)

 

Below is the comparison btw the Nivalis 7 and 7.5:

 

7, ET45 (same I have)

Not my car - but it looks the same

 

 

7.5 ET45, on FL models 2017 onwards

I didn't realised FL models don't have the door trims - much more balanced IMO, this gives me ideas for the future!

 

 

 

There are also 18x7.5 ET43 for Scout3 FL (Braga alloys), and Golf7 Alltracks  (same chassis and suspension of Octavia Scout) come with 18"x7.5, ET45.

 

 

I'd say this all corroborates 7.5 channels with ET40 to 45 does fit no problem

There's a mistake in the listing that you've linked to.

 

The 5E0601025AR 8Z8 alloy rims are 7J, not 7.5J as you can see below in the Skoda parts catalogue.

I doubt the Octavia MK3 Scout ever left the factory with 18" rims. The only wheels listed in bold on wheel-size.com for this car are 225/50R17 7Jx17 ET45.

 

In the VW parts catalogue, there are 7.5Jx18 ET45 alloy rims listed for the Golf MK7 Alltrack. You could use those with 225/45R18, but the ride will be harder and the protection from kerbing damage will be far less as shown in the below chart. Over 15mm of tyre sidewall bulge each side gives good protection from kerbing damage. Less than 12mm of tyre sidewall bulge each side gives poor protection from kerbing damage. As you can see below, 225/45R18 fitted to a 7.5J rim has very little sidewall bulge each side, so gives very little protection from kerbing damage. Even if you fit the 225/45 to 7J rims, you still only get 8.6mm of sidewall bulge each side. For excellent sidewall protection from kerbing damage you really need to be looking at 50 aspect ratio tyres and above...such as 225/50R17.

Hi. Did you ever make the change to different wheels. If your Nivalis are available I may be interested.

Same era Skoda Yeti wheels are 7x17 ET45 btw

OP is located in Australia. I reckon the shipping will be prohibitively expensive 😅

yep, I knew that but I'm a patient man... could go cheap and slow!
