All, quick question.

I've read that 16" x 6.5J, PCD 5x112 ET50 is a good/the right match for the Octy for winter wheels (I have a VRS). My question is do we have to use precisely this size or can there be any variation i.e. ET45? I've never changed from the stock wheels on a car so I have no idea what some of these measurements are, or how a small difference may effect the car.

If other sizes can be used on a 2006 TFSI VRS, please could someone state what they are.

Thanks in advance.

If the other measurements are the same (pcd, diameter, width) and only the et is different by 5mm you're going to be fine. ET45 pushes the wheel 5mm further out compared to ET50.

HTH.

just re-read your first post - i'm assuming you mean pcd is 5x112, if so, that's right. Never seen it written down the way you have..

I'm hunting down some audi 6x6.5" wheels which are ET42. This will put the outer edge pretty much exactly where my 17x7's sit but will give me a whole half inch extra clearance to the strut on the inside.

Sorry, i've edited my post and that is indeed what I meant.

What is the highest and lowest EFT (offset?) that can be used on a pre-facelift VRS? I'm also assuming that this doesn't change across the range so this info will hopefully benefit others

Also, would 7J fit or do they HAVE to be 6.5J?

7J would be OK but is quite unusual for a 16" wheel, certainly within the VAG stable.

You could also use a 17" rim if you want, I run my winters on my standard Elegance 17" wheels.

Cheers Wardy, what the wheel size I am looking for if I can track dow 17's?

The 7J wheels I have seen are VAG ones strangely enough, could be the seller has the info wrong...

7J is typical for a VAG 17" - that's what my Pegasus wheels are.

Think they're ET51 but I'd have to double-check. They will be in that area anyway.

Then the typical tyre size is 225/45/17 or 205/50/17.

My 6.5 x 16 Vega wheels are ET50, so that is the standard on the octy.

By using ET45 you are altering the relationship between the centre point of the tyre and the centre point of the suspension are. This will make the steering heavier and could lead to increased tyre wear. There is a technical term for this, but it escapes me at the moment. Something to do with king pin inclination?

My wheels are for sale at the moment :-)

Don't forget the ET needs to be used in conjunction with the wheel width, if you change the wheel width but keep the ET the same then the wheel will still sit differently on the car!

I meant ET42 in relation to the 6.5J rim as per the OP but can't seem to edit my post from my mobile.

This will move the centre line of the tyre outwards so will make the steering heavier, similar to putting spacers on.

Probably not noticeably though.

Lets be honest tho, using these winter tyres and wheels in the winter your not going to flying about daft anyway.

I thought that was the whole idea of fitting winters :-)

The term I was thinking of was scrub radius, but I had it the wrong way round I think, it might make the steering slightly lighter. Whatever, a few mm is hardly going to make a difference.

My car right now has 17x7J with et50 on it.

16x7J with ET50 (I have found audi wheels this size) would keep the tyre location exactly the same.

16x6.5J with ET50 will keep the tyre location exactly the same but the rim edges will be 1/4" in on each side.

16x6.5J with ET42 will keep the outside rim location pretty much the same (8mm-1/4" is 1.7mm) compared to the 7" ET50's but move the inner edge in by 8mm+1/4" which is about 14mm.

Thanks for all th info guys.

AndyVee, as you've mentioned it here and I see you have had no firms responses on the For Sale board, can I have first dibs on these if you're willing to courier them?

Sorry to highjack the topic, but whilst its on the subject of tires :

I have a set of 8x17 ET33 alloys which are going on my Octi at some point. After some research, I've come to the choice that 225/45/17 tires will be fine? What does everyone else run tire wise?

17" 8J, ET33 won't work with the Octy Mk2. Offset is too low, on standard suspension anyway.

But on the tyre question, yes 225/45/17 will do fine. You can use 205/50/17 as well, if you prefer.

Won't 205's be seriously stretched on an 8" rim? At a minimum looking terrible and exposing the rim edge to all manner of evils.

I'm meaning on a normal 7J 17", not the ET33 wheel suggested, just to be clear.
