I have mucked up a bit and need a bit of advice. I wanted to get rid of my R19 wheels for a smaller size so when I was offered some R17 Audi alloys really cheap i checked the bore size and studs were the same and bought them. I sold my original "R19,s with the intention of putting the extra money towards 4 new tyres for the 17"rims, but here is the thing, The  number for my originals is ET47, the Audi ET is 33 so is it best to buy some spacers or cut my losses and get some more alloys ? Never knew about  offset or ET numbers until now

Don't use spacers with ET33 rims on the Karoq. This is because spacers reduce the offset, so 10mm spacers would change the effective offset from ET33 to ET23, and 15mm spacers would change the effective offset from ET33 to ET18.

 

What is the full specification of the 17" Audi rims?

 

These details are cast into the alloy rim, often on the back. You might need a magnifying glass as these details can be quite small.

 

For example, the rims might be 6.5Jx17 ET33

 

It sounds like you have already checked that the PCD is 5/112, and that the centre bore is 57.1mm?

 

If they are ET33, they should be ok to use on the Karoq 4WD with non-standard 215/60R17 tyres.

 

215/60R17 are generally a cheaper tyre size than the standard 225/55R17, so multiple the savings by 4.

 

Another advantage of 215/60R17 over 225/55R17, is that the ride comfort is improved even further.

 

Compared to the hard riding 225/45R19, it will be like riding on clouds.

 

I think you will find that your 19" rims are 8Jx19 ET45 if they are original Skoda Karoq rims.

For best ride comfort, avoid over-specifying the tyre. For example, don't choose an eXtra Load XL tyre if a standard load tyre will suffice, and don't choose a V-speed index tyre if an H-speed index tyre will suffice.

 

Here's an example of a Standard Load SL all-season tyre with an H-speed rating in the 215/60R17 tyre size.

"For example, the rims might be 6.5Jx17 ET33"... I dont know what they measure "J" wise.

The17,s along with the tyres they came with ( winter Pirelli scorpions 215/60/17 ) were put on my car a couple of weeks ago. The tyres make a noise like the hum of an electric generator, but i put this down to the winter tyres with only 3 or 4 mm of tread. It was only a couple of days ago researching  for a set of new tyres that i came across the ET numbers and looked into it further. The 17,s ET33 seems quite a big gap from the original ET45 but thats the limit of my knowledge 

" I think you will find that your 19" rims are 8Jx19 ET45 if they are original Skoda Karoq rims." ............ yes they were

It sounds like the alloy rims were from an Audi Q3.

 

The alloy rims should have the OEM part number on them, usually on the back.

 

What is the OEM part number of these rims?

 

The OEM part number looks something like 8U0601025E or 8U0601025Q, etc.

Yes they were from the Q3 so the bloke said. I cant get the OEM numbers now as its too dark but i can try looking tomorrow if you want ?

This didn't get answered, so here you go.

J is shape of the flange, not a measurement.

Are the flanges all different as well ?

Maybe someone knows, but I've only ever seen J for the VAG wheels I have looked at.

 

Try a little Google-Fu skills to research the choices of flange types, may as well turn today into a learning opportunity 😉

It might just be me being thick but i am amazed at how complicated things have gotten. Back in the day it was only a choice between cross ply or radial 😀 , even then it was an easy choice depending on how much you had in your wallet 😀

Well if you're talking rubber, then you have choices

Spoiler

• No grips
• Ditch finders
• I sheet my pants
• 365 condoms and call it a GoodYear

Anyhow I strayed off topic, but if it made you smile 😄

 

 

EDIT: Being serious for one moment, I never bothered too much with all the tyre snobbery that can exist, I just had a mobile tyre fitted that I trusted to fit something that would keep me as a repeat customer.

The OEM part number is 8U0071497, ET 33mm  6.5jx17

8U0071497 is shown in the accessory catalogue for the Audi Q3 as shown below. These alloy rims are sold to be used with 215/60R17 winter tyres on the Audi Q3.

Yes, the 12mm difference in the ET number is 3 times over the max for the Karoq, shame as they looked good and easily handled the terrible pot holes that i have in my town. Just have to get another set and make sure i get it right next time ☺️ Would i be right in thinking there are only the 18,s or 19,s as standard wheel options for my model Karoq  ?, Thanks for the help.

It's not 3 times over the max because the max isn't ET43. That's simply one of the standard offsets that the Karoq uses.

 

As well as 215/60R17 fitted to 6.5Jx17 ET33 rims, you could also use 235/55R17 fitted to 7Jx17 ET43 from the Audi Q3 on the Karoq 4WD.

 

wheel-size.com have only recently started saying offset range ET41-ET45 when referring to an ET43 offset. This just leads to confusion. They do this with every car not just Skodas.

 

wheel-size.com are simply covering themselves, as some cars such as the Superb MK3 use more than one offset for the same diameter of rim such as 17".

 

Two different 17" rims for the Superb MK3, ie. 6.5Jx17 ET41 and 7Jx17 ET40

wheel-size.com only list the 7Jx17 ET40 rim for the Superb MK3, and not the 6.5Jx17 ET41 rim.

https://www.wheel-size.com/size/skoda/superb/2018/

 

So what wheel-size.com are saying when they give a +2mm or -2mm range of offsets, is that there may be more than one specification of rim for any one particular diameter of rim that the manufacturer offers. It has nothing to do with making a judgement on what alternative non-standard rim offsets are acceptable.

I read that you can go over or under offset by 3 or 4 so if the Audi rims i put on had an offset of 33mm and they should be 45mm thats 12 mm difference

That would mean that nobody could use wheel spacers, even 10mm ones because that would change the offset by more than 4mm.

 

wheel-size.com aren't experts on offsets, they just compile lists...often with many mistakes.

Thats a good point Carliston. Done some more research and although one said  vaguely it could affect wheel bearings it was more to do with wheels coming outward and rubbing on wheel arches or inward and rubbing brakes or suspension. Think what i will do now is put new tyres on the Audi rims and see how they go. If there is no adverse effects i am quids in by not having to buy another set of rims needlessly 👍

I have learnt much from this thread!

But now I will need to take paracetamol and go for a lie down....

It was a steep learning curve for me and certainly done my head in as well 😀

It’s not rocket science……

When changing offsets either through different offset rims or using spacers, someone always jumps up and claims that your wheel bearings won't last. This has been going on for decades.

 

However, I've checked the front wheel bearings on the Karoq 4WD and they are exactly the same as the later Audi Q3 front wheel bearings. Clearly, the Audi Q3 6.5Jx17 ET33 rims can also be used on the Karoq 4WD without damaging the wheel bearings.

 

 Audi Q3 and Karoq 4WD front wheel bearings are exactly the same as shown in the photo below
