hello everyone. I have a 2023 model 1.5 tsi karoq sportline car. original vega 225 40 19. My friend bought an audi a6 and removed the 245 45 19 tires with 0 km. I have a complaint about my 40 cheeks. Is it compatible with 245 45 19 Vega rims? Will it rub? Has anyone tried it?

Greetings to everyone from Türkiye

Sorry but I have no info regarding clearance.

 

However will they be legal?  Bigger rolling diameter will cause the speedo to under read and that is the problem.

His current tyres are not 225x45 19".

Normally, there are people who install 235 45 R19 tires and are satisfied, but they are very expensive in Turkey. 245 or 225 are almost half the price. 225 makes the vehicle look skinny, there are people in cupra formentor groups who wear 245 45 19, but I know the platform is different. Likewise, the case without make-up, but I talked to a person who installed original 19 rims and 245 45 19 tires, he is very satisfied, there is no rubbing.

Sorry typo, but figure is correct tyres are 40 mm larger in diameter.

That's correct.  The difference is 6.1%.  The tyres should fit. The speedo will under-read by 4.3 mph at 70 mph.  But as the speedo on my Sportline over-reads by 3 mph at 70 mph, the net effect will be a speedo that under-reads by around 1 mph at that speed.  An under-read is illegal, at least in the UK, but nobody is ever going to check, nor prosecute for such a trivial error, and in any case it will disappear as soon as the tyres wear down a bit.  One would just have to remember not to rely on an over-reading speedo when approaching a speed camera.

 

Keeping the speedo error within prescribed limits is a car maker's concern. As long as the user mounts wheels from the approved wheels list, they are not responsible for any speedo reading inaccuracy. Mounting wheels that are not approved is illegal, but still, excessive speedo error is not the main reason for that.

What I'm wondering is, will there be friction?

My 245/40 19s have clearance to spare, but my guess is that 245/45s could be close to, or over, the limit at the inner edge of the rear tyres unless you want to start butchering the wheel arch liners. But this is merely a guess. 

Is the offset (the ET figure) the same for both wheel/tyre combinations?

The OP has 8Jx19 ET45 5/112 57.1 VEGA alloy rims

https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-vega-19-karoq/p/57A071499B+FL8

 

Rather than 245/45R19, I suggest you use 245/40R19 because someone has already tried 245/40R19 on their Karoq 1.5TSI front wheel drive and they work very well on the standard Karoq rims.

 

However, it's easy to get carried away with wide low-profile tyres when narrower higher profile tyres will not only give a better ride but better fuel consumption and less noise.

 

The standard 17" rims on the Karoq have a specification of 7Jx17 ET45 5/112 57.1. For a personalised look, perhaps look at 6.5Jx17 ET38 5/112 57.1 from the Kodiaq instead together with the standard Karoq front wheel drive 215/55R17 or an oversized 215/60R17 tyre size. The ET38 offset of the Kodiaq rims will move the centre of each wheel 7mm further out in the wheelarch, which increases the front and rear track by 14mm...for that personalised look. The narrower 6.5J rim will slightly improved the ride comfort compared to fitting the 215 tyres to the standard 7J Karoq rims because narrower rims help the sidewalls to flex more easily.

 

Notice in the two tyre examples below, that by specifying sensible tyre sizes you can avoid the massive over-specification of the speed rating...which won't help the weight or flexibility (ie. comfort) of the tyre. Also, most tyres in the 245/40R19 size are XL which again won't help the flexibility (ie. comfort) or the tyre.

 

Another advantage of 17" rims instead of 19" rims is a large weight saving...perhaps 2.5kg/rim or 10kg for all four rims...or 12.5kg for all five rims if you carry a spare...and that applies to either steel or alloy rims because so called "lightweight" alloy rims tend to be just as heavy as steel rims.

OP'de 8Jx19 ET45 5/112 57.1 VEGA alaşım jantlar bulunur

https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-vega-19-karoq/p/57A071499B+FL8

 

245/45R19 yerine 245/40R19 kullanmanızı öneririm çünkü birisi zaten Karoq 1.5TSI önden çekişli modelinde 245/40R19'u denemiş ve standart Karoq jantlarda çok iyi çalışıyor.

 

Bununla birlikte, daha dar ve yüksek profilli lastikler yalnızca daha iyi bir sürüş sağlamakla kalmayıp aynı zamanda daha az gürültü yapıp daha iyi yakıt tüketimi sağladığında, geniş, düşük profilli lastiklere kapılmak kolaydır.

 

Karoq'un standart 17" jantları 7Jx17 ET45 5/112 57.1 spesifikasyonuna sahiptir. Kişiselleştirilmiş bir görünüm için standart Karoq önden çekişli 215/55R17 veya Kodiaq'ın 6.5Jx17 ET38 5/112 57.1 jantlarına bakabilirsiniz. Kodiaq jantlarının ET38 ofseti, her bir tekerleğin merkezini tekerlek yuvasında 7 mm daha dışarıya taşıyacak ve bu da ön ve arka izi 14 mm artıracak... Daha dar 6,5J. Jant, 215 lastiklerin standart 7J Karoq jantlara takılmasıyla karşılaştırıldığında sürüş konforunu biraz artıracaktır çünkü daha dar jantlar, yanakların daha kolay esnemesine yardımcı olur.

 

Aşağıdaki iki lastik örneğinde, makul lastik boyutları belirterek, hız değerinin aşırı spesifikasyonundan kaçınabileceğinize dikkat edin; bu, lastiğin ağırlığına veya esnekliğine (yani konfora) yardımcı olmaz. Ayrıca 245/40R19 ebadındaki lastiklerin çoğu XL'dir ve bu da yine esnekliğe (yani konfora) veya lastiğe yardımcı olmaz.

 

19" jantlar yerine 17" jantların bir başka avantajı da büyük bir ağırlık tasarrufudur... belki 2,5 kg/jant veya dört jantın tümü için 10 kg... veya yedek bir jant taşıyorsanız beş jantın tümü için 12,5 kg... ve bu çelik veya alaşım jantlar için geçerlidir çünkü "hafif" olarak adlandırılan alaşım jantlar, çelik jantlar kadar ağır olma eğilimindedir.

Thanks for the reply and information. But I don't want to change rims, I will only change tires. either 225 45 19 or 245 40 19

225/45R19 and 245/40R19 are the standard 19" Karoq 4x4 tyre sizes. By comparison, the standard 19" Karoq front wheel drive tyre sizes are 225/40R19 and 235/40R19.

 

As you can see in the chart below, the 245/40R19 when fitted to an 8J rim has an actual inflated width 11mm wider than the 225/45R19 tyre size when fitted to an 8J rim. As the 8J rim has an actual width of about 227mm, the sidewalls on the 225/45R19 tyre when fitted to this 8J rim will hardly bulge out at all, ie. only about 4mm or 2mm each side. By contrast, the sidewalls on the wider 245/40R19 will bulge out by about 15mm, ie. about 7.5mm each side. This will result in the wider 245/40R19 tyre giving much better protection to the alloy rim from kerbing damage.

 

Actual inflated width of tyres when fitted to 8J rim width (measured from the outside of one sidewall to the outside of the other sidewall, at the widest point) 

225/45R19 231mm

245/40R19 242mm (11mm wider compared to 225/45R19)

Aşağıdaki tabloda görebileceğiniz gibi, 8J janta takıldığında 245/40R19, 8J janta takıldığında 225/45R19 lastik boyutundan 11 mm daha geniş bir gerçek şişirilmiş genişliğe sahiptir. 8J jantın gerçek genişliği yaklaşık 227 mm olduğundan, bu 8J janta takıldığında 225/45R19 lastiğin yan duvarları neredeyse hiç çıkıntı yapmayacaktır; her iki tarafta yalnızca yaklaşık 4 mm veya 2 mm. Buna karşılık, daha geniş olan 245/40R19'un yan duvarları yaklaşık 15 mm kadar dışarı doğru çıkıntı yapacaktır. her iki tarafta yaklaşık 7,5 mm. Bu, daha geniş 245/40R19 lastiğin alaşım janta bordür hasarına karşı çok daha iyi koruma sağlamasıyla sonuçlanacaktır.

Can you give me tire sidewall height values for 225 40 19, 235 45 R19 and 245 40 19?

My main goal is to raise the sidewall and wheels a little and widen them a little. because the car looks a little skinny from the back

89 mm, 107 mm, and 99 mm.

 

You can look up all the tyre dimensions here: https://tiresize.com/tyre-size-calculator/

To work out the sidewall height of a tyre, multiply the nominal tyre width by the aspect ratio.

 

For example, 225x0.40=90, 225x0.45=101.25, 245x0.4=98.

 

Sidewall height of tyre

225/40 90mm

225/45 101.25mm

245/40 98mm

 

To work out the outside diameter of a tyre, first convert the diameter of the rim into millimetres and then add twice the sidewall height.

 

For example, 19x25.4+2x225x0.4=662.6, 19x25.4+2x225x0.45=685.1, 19x25.4+2x245x0.4.

 

Outside diameter of tyre

225/40R19 662.6mm

225/45R19 685.1mm (3.4% bigger compared to 225/40R19)

245/40R19 678.6mm (2.4% bigger compared to 225/40R19)

Funny thing is the comparison would mean that my speedo would be almost 100% accurate as they are designed to overstate speed. (225/40R19 versus 245/45R19)

Can't spell - duh

Sorry to jump on thread - I am interested in a new 1.5 DSG Sportline (fwd) - at present it comes with 225/40R19. However, I understand the 4wd 2.0 DSG Sportline comes with 225/45R19 or at least I think it does (the technical spec part on page 31 of the brochure shows 225/55R19 - which I think is probably an error - but the build your own says it comes with 225/45R19 (in basic price section) but also confusingly then shows 225/55R19 again under my equipment/standard equipment section. I know I am rabbling on but my question is, before the build week could I in theory ask my dealer to ask if the 2.0's 225/45R19 (assuming they are probably correct size fitted) or if not the 225/55R19 be fitted, instead of the 1.5's 225/40R19 ? Just trying to see if having a higher ratio sidewall may help comfort side of things! If they could be swapped at build stage, does this have any bearing on true speedo reading or does the factory automatically calibrate the speedo depending on the supplied/fitted wheel/tyre size?

 

Hopefully I have made some sense!

Here are the relative comfort levels of the Karoq tyre sizes, all other things being equal.

 

225/60R16 best

225/40R19 worst

 

Here's some examples of over-size (non-standard) 16" and 17" wheels for the Karoq. If the speedo is over-reading by about 3% to 4% when on standard Karoq tyre sizes, these over-size tyre sizes should make the speedo reading almost spot on.

Thanks for that. I did think that would be the case in terms of actual factory fit sizes. It does bug me when there’s so many errors on the brochures. Sometimes I think I know more than Skoda.😀 - I spotted other errors in the past and made them aware. Now I just need to try to get an answer regarding whether I could swap the 40 profile for the 45 profile, on a 1.5 DSG Sportline as part of the build process. I’m assuming that the 45 profile is fitted on the four-wheel-drive variant due to the extra weight of the car? I suspect the dealers will say no as they seem pretty in flexible in my view - I also suspect the 45 profile tyre maybe cheaper than the 40 but I don’t expect that will make any difference to their view of things. 

Thanks for the informative reply.

 

 Anyone happen to know about my other question about whether the tyre size can be swapped at build stage by Skoda and if so would they recalibrate the speedo (assuming it needs that) at that point?

Some did this in the very early days of the Yeti (going from 17" to 16" wheels).  They bypassed the dealer going direct to Skoda UK asking them to amend the build spec.  Needless to say Skoda stopped it after a short while.  There was some discussion on the Yeti Forum.

 

There is nothing to stop you asking Skoda UK although I wouldn't get your hopes up.
