A refugee from the Yeti forum seeking advice from those who hopefully know?

 

We're about to take delivery of a Karoq Edition 190 DSG which comes on 19" Crater alloys. We have a set of 17" Annapurnas from the Yeti shod with Vredestein Wintrac Pros (7+mm)  - would these be OK as winter wheels on the Karoq or should we sell them? Any advice greatly appreciated.

 

Thanks in anticipation,  Robin

The wheels will fit, but will need wider and/or higher profile tyres to retail a legal rolling radius and speedometer calibration.

Thanks Ken - think I'll sell on the Annapurnas and buy 19" winters then.

The 17" rims approved by Skoda for Karoq are all 7J wide with ET45.

 

There is no such thing as an 'illegal' rolling radius in the UK..

 

Yes you want your speedo accurate or over-reading as they come from the factory.

Yes you want the correct speed and load rated tyres and of the correct rolling circumference and diameter.

Well, not in so many words if you're being pedantic. There is a legal tolerance on speedometer calibration though, and changing wheel diameter without fitting appropriate size tyres is the usual way people break that tolerance.

@KenONeill

I read your pedantic posts on Torsion beams so lets be pedantic.

?

Can you tell me at which MOT station the speedo accuracy is checked, or which Officer of the law checks them and maybe find me a prosecution in England / Wales, Scotland or Northern Ireland for a speedo under reading?

 

There will be those caught speeding. I have just paid my 2 fines.  But then the speedo was accurate, just my speed was above the Legal Speed at the time.

Without wishing to hijack the OP's thread but having an ongoing decision as to what to do with mine, I've seem this table before and it's really useful.... or it would be if I knew which Motor type the 190 TDI DSG was...! Any help appreciated!

 

Sorry OP!

Not sure what the Edition 190 comes with but if it's 225/40/19 rather than 225/45/19 then you may well be struggling with winter tyres. The '40' isn't really enough for winter tyres to be effective.

 

If it were me, I'd use the tyre size calculator and reduce the wheel diameter in order to have a larger ratio - '45' at a bare minimum. Those Annapurnas might still come in useful.

 

I thought our Edition ( 150 ) came with 45 ratio, so was an eye opener to see '40' tyres on our car. I thought about changing alloys / tyres but then decided to change tyres on the Octavia to All season and if snow forecast, just leave Karoq in the garage. Couldn't have worked out any better as the All Season's cured the road noise issue on Octavia. Would be great if they did them for karoq because 19" Crators kick up a fair amount of noise.

I'll see what size tyres are fitted when I collect and then decide! Thanks!

The Winter tyres available in 225/40 R 19 are perfectly good ones and really the profile means very little. 40% of 225mm is fine as a sidewall height unless going rock crawling.

On my continental Karoq 2019 the engine code is found on a label low down on the central 'B' right doorpost.

Well, if you will drive through pot holes that deep...

Merlinman,

 

If you decide to sell your winter wheels I could well be interested.

Hi Karock, this wasn’t/isn’t a sales pitch, but from the advice to date here and elsewhere it does seem I might be better to move the spare Annapurnas and tyres on and put the proceeds towards a set of winters for the Karoq. I’m currently looking at tyre size options. 
I’ll be removing the winter wheels and tyres next Monday when I’ll photograph them. Basically there’s a set of 4 unmarked Annapurnas which I had powder coated last winter (they were polished/lacquered - which is not a lastingly durable finish and a set of Vredestein Wintrac Pro ( in the correct weight rating) which have at least 7mm of tread.

Let me have an email and I’ll send you pics early next week?

Where do you get your information from re: their effectiveness? or the profile means very little? Winter tyres on that size of wheel will not work to the same level as one with a 50 profile tyre. Winter tyres work due to their softer compound...  not a great combination on such low profile tyres.

 

The 225/40/19 winter tyres are about as popular as a fart in a spacesuit. How many All season tyres can you find in that size?

Sorry, but that's gone straight over my head. What do mean?

Edited 19 February, 20206 yr by Guest

@Scot5 I get the tyres, use the tyres and drive in the conditions the tyres were designed for and get my information, and that has been lots of tyres.

 Do i have to post the pictures of many many sets of winter, all season and snow tyres i have in my sheds and garage?

Then Mud Tyres, All Terrains and M&S market tyres.

The tyres section has as many posts or threads of some i have had fitted and reviewed.   I have a rubber fetish.

 

Winter tyres work with the compound and the tread pattern and the sipes. and really the sidewall height just gets the wheel further away from the ground.

You post some right rubbish. You jump on what i said and i posted available an example of 3 winter tyres in 225/40 R 19. 

 Then ask about how many 'All seasons' i can find in that size.

 

No idea how often over the years you have used Winter or snow tyres or All Season tyres but personally i have ran plenty of all 3 tyre types on snow and ice and up to the Scottish Ski centres and back  in a 215/40 R 17 or 205/45 R 17 and they have been effective.

 

Just in the likes of Tyre Leader there will be a dozen Winter tyres showing in 225/40 R 19.

Only 7 All Season tyres right enough.

 

Anyone fitting them are not going to find them in that size if that is what they needed as being less effective as the 225/45 R 19.

 

225/45 R 17 Snow tyres run all year for 2 years on the Volvo.

Happy as larry on the Snow in winter or across the Scottish 'Snow Roads' of the A93 & A939 in high summer.

Car speedos under-read by about 5% when on standard tyres.

 

Fitting 225/50R17 instead of 215/55R17 will make the speed more accurate, not less accurate.

 

There's less than 2% difference between the outside diameter of 215/55R17 tyres and 225/50R17 tyres. They are for the most part interchangeable, at least in the UK. It's always best to notify any modifications to your insurance company, but they may not regard this small change as significant. It's worth pointing out that a 225/50R17 tyre needs a rim width between 6J and 8J, and a 215/55R17 tyre needs a rim width between 6J and 7.5J...so a 7J is well within the allowable range for both tyre sizes.

 

On a 7J rim, I prefer the fit of a 225/50R17 tyre to a 215/55R17 tyre. When fitting a 215/55R17 tyre to a 7J rim, you are starting to stretch the sidewalls which makes the ride harder and offers less protection from kerbing damage. Also, 225/50R17 is a more common size and often cheaper. If you wanted to fit the new Vredestein Quatrac Pro, these aren't even available in the less popular 215/55R17 size, but are available in the 225/50R17 size.

 

Another option is 225/55R17. Again, less than 2% difference in the outside diameter of the tyre compared to the 215/55R17 size. This is a standard size on 4x4 versions of the Skoda Karoq, and is also fitted to the same 7Jx17 ET45 rim size.

Yes, but back up thread we were talking about swap between 17 and 19 inch wheels, with no tyre size specified. That's a change of 25.4mm in rolling radius if we stick to, say, a 215/55 tyre on each set of wheels.

You were the one who started talking about "19 inch craters"?

Beginning to regret asking a simple? question - decision made to sell on the Yeti Annapurnas - thanks to those who contributed!

That's very interesting Carlston, what you say about best width of tyre for a particular wheel width and the effect on ride.  So my 215 55 Bridgestones on 17" 7J wheels adversely stress the sidewalls a bit.  If I change to 16" 6J wheels, that looks like an optimum fit, plus I go for the Goodyear 4 Seasons tyres, there'll be a triple benefit as far as ride over ridges & potholes is concerned    :-

1.       Taller profile 60 instead of 55.

2.       Goodyear All weather tyres quieter & more comfy anyway than Bridgestones.

1.       AND NOW, 6J wheels better suited to 215 tyres, than the wheels on my car.

Some downsides no doubt - slight economy hit & dry handling not so sharp, almost certainly.

Fitting 215/55R17 to any "allowable" rim width doesn't adversely stress the sidewalls or doing so wouldn't be allowable.

 

215/60R16 tyres fitted to 6Jx16 ET43 rims is another standard option on the Skoda Karoq. 6J is the minimum allowable rim width that you can fit a 215/60 tyre to.

 

You could also consider higher sidewall 215/65R16 tyres fitted to the 6Jx16 ET43 rims. This tyre size is a standard fitting on the popular Dacia Duster, although Dacia fit 215/65 to 6.5J rims not 6J rims.

 

This doesn't relate to the Skoda Karoq, but 205/55 used to be most commonly fitted to 6.5J rims and 185/55 to 6J rims. Nowadays, Skoda often but not always fit 205/55 to 6J rims and 185/55 to 5.5J rims for a slightly softer ride. Even when fitting tyres to slightly narrower rims, you still get the full amount of grip, just not as sharp handling.

 

Maybe consider 215/55R17 or 225/55R17 fitted to 6.5Jx17 ET38 steel rims from the Skoda Kodiaq. You get the 6.5J rim width and increase the front and rear track by 14mm compared to the ET45 offset.

 

6.5Jx17 ET38 5/112 57.1
