Since we're on a wheels topic and I'll soon put on my winter 'shoes', does anyone here know the torque for the Octavia wheel bolts? Is it 110 Nm as I knew from other brands? (this being my first VAG car)

120 Nm by the looks of it...

 

https://www.wheelfitment.eu/car/Skoda/Octavia (2020 - ).html

 

https://www.wheel-size.com/size/skoda/octavia/2021/#trim-20-tsi-eudm-241

 

 

 

 

It says 140 Nm in the manual: Wheels > Changing the wheel and raising the vehicle > What you should be mindful of

https://digital-manual.skoda-auto.com/w/en_GB/show/708c3bafe83886dcac6ba38ab4af34a0_11_en_GB

 

For Octavia III it is 120 Nm.

K, thanks for that; I was too lazy to check the manual - thought it would be faster on the forum.
BTW, those 140 Nm seem quite a lot; I wonder why would Skoda go up from 120 to 140 between MK3 and MK4. Most of the torque values I've seen so far (not only for Renault) were typically 110 +/- 10%.

i ve put Nokian (like i ve done on many other car) on the factory 18" and they re really noisy on the octavia, first time i m so disapointed by this brand of tires !

I guews it depends on the exact model. I used to have Nokian before, but 16 inch. Can't remember the exact model, think it was D4, or something like this. They were very quiet, compared to the EcoContact5 I had for the summer...

I used 120Nm dispite the manual stating 140Nm.I searched (googled) quite a lot and most Vag group cars Golf,Cupra Leon etc seemed to say 120Nm as did the wheel calculators.Correct answer is to contact your dealer I guess.

Well, actually @stripy007 is right, the official Octavia manual is indicating 140 Nm. And concerning the dealer - it wouldn't be the first time I'm asking a question to the dealer and get the wrong answer...
But indeed, 140 Nm seems excessive. 

I assumed it could be a misprint and also assumed the dealer by which I mean the techs who service the cars would have correct value.

 

I take your point though.(never assume)

So you're comparing summer tyres Goodyear EfficientGrip 1 or 2? of which size? to winter tyres Continental VikingContact 7 of which size?

Summer tires: Goodyear EfficientGrip Performance 1. 205/55R17

 

Winter tires: Continental VikingContact 7 205/55R17.

Efficient Grip Performance. The size is 205/55/17.

Anyways, got fitted today original size BF Goodrich winter ones. And immediately was shocked at how silent were they compared to the stock Goodyear. Indeed, miles difference.

To be honest, I didn't expect such a big noise difference, even after your post...
...but the time came to compare my winter set with the factory one. Huge difference between the silence of the Bridgestone Blizzak LM005 Extraload (on 16" rims) and the noise/resonance of the Goodyear Efficient Grip (on 17"). They're the same width, I used the same pressure (~2.6) but there's no comparison between the noise level. It's the first time I was able to hear some faint aerodynamic noise at high speed (either from the A-pillar or from the side mirrors - not sure); with the summer set it was covered by the tire noise. Finally, the car sounds fairly well soundproofed; I was quite disappointed with the summer tires, which means that (at least for me) the Goodyear's are rubbish and I'm looking forward to replacing them.

I've managed to find a set of 17's winter alloys from an Audi Q2, almost brand new. The dimensions are identical to my factory fitted ones - Pulsar Aero rims. 7J, 5x112mm, ET 45. The only difference is one mm wider offset, but that is not really a difference. Took them to the paint shop and anthracite grey coating was applied than Fulda Kristall Control HP 2 installed. Also, the center caps are replaced with Skoda ones from Aliexpress. The only downside I see is, that the winter alloys are heavier than the the Pulsars.

Nice one! is the width of the standard MK4 7J? I thought it was 7.5J, or at least this is on the vRS...

Thanks for sharing this.

 

Does anybody drive Hankook icept evo3? On tyre review it performed quite nice (except for the noise) and I could get it for much cheaper than Bridgestone or Continental.

 

Is Hankook really that noisy/uncomfortable?

 

My summer tyres are Bridgestone Turanza T005.

I had them fitted to 16" Audi A3 alloys on my old Mk5 Golf.  I wasn't particularly impressed by them.  The Golf was mapped to 210 bhp and 330 lbs-ft and on the Hankooks it was very easy to overcome the traction control, resulting in massive wheelspin.

On snow and ice, they weren't a patch on the Dunlop D4 Winter Sport and D5 Winter Sport which I've run on three VW Tiguans and our current Karoq over the years nor as good as the Michelin CrossContact + currently fitted to my Yeti.

Sorry for the absence. 

 

So for rims I'll be looking at (I think 18" rims) and Continental 870TS or Bridgestone LM005s

 

Just need to know the J size for the rims.

Oh do they supply the right size bolts? Or do I need to buy them separately? 

 

Ta.

I just looked here - Skoda Octavia 2019 - Wheel & Tire Sizes, PCD, Offset and Rims specs - Wheel-Size.com. It seems that you need 

225/40ZR18 92Y

7.5Jx18 ET51

 

As to the bolts - when I bought my Dezent wheels, I got the bolts with the wheels. Only used four of them per wheel and the original locking bolt.

 

I got 7.5J x 18 and Conti 870TS.

7.5Jx18 ET51 is the standard 18" size for the Octavia MK3.

"skoda eshop cz" alloy rims

https://eshop.skoda-auto.cz/en_CZ/alloy-wheels/c/alloyWheels?sort=priceAsc&q=%3AscoreDesc%3AcarType%3AOctavia%2BIV%2B%282019%2B%29&show=Page#

 

If you use VAG group alloy rims, the wheel bolts are all the same...at least with 5/112 VAG rims.

 

I would avoid aftermarket rims, because they tend to use different wheel bolts and they will often need spigots because the centre bore of aftermarket rims is usually larger than the Skoda's 57.1mm diameter. Also, aftermarket rims will often use a different width and offset so a car insurance company might regard that as a modification. Yet another problem with aftermarket rims is finding a single replacement if one gets damaged. It's much easier to find a single replacement VAG rim. Aftermarket rims won't usually quote their weight because they will often be very heavy so the sellers will quietly keep the weight secret from any potential buyers...perhaps with a sales tactic of saying, " we don't quote the weight because that might vary slightly from wheel to wheel". However, weight can also be a problem with VAG rims.

 

For a cheap and light steel rim, you could do a lot worse than fitting a 6.5Jx17 ET38 5/112 57.1 steel rim from the Kodiaq together with a 205/55R17 tyre...instead of a 225/45R18 fitted to a 7.5Jx18 ET48 5/112 57.1 rim. Because of the ET38 Kodiaq's offset for this rim specification the outside of the 205 tyre will be in about the same place as the 225 tyre fitted to an ET48 rim. So although 205 is about 20mm narrower than 225, you wouldn't get that sunken in the wheelarch look. Another benefit of this 205 option, is the 20mm wider track because of the ET38 offset compared to the ET48 offset.

 

6.5Jx17 ET38 5/112 57.1 steel rim (from the Kodiaq)

https://www.mytyres.co.uk/rims/details?vehicleId=672860434273997936&rimCode=ALCAR9021

 

Weight of rims

6.5Jx17 about 10.5kg

7.5Jx18 about 13kg

 

For four rims, there could be a weight saving of about 10kg (4x2.5kg) by choosing the 17" steel rim option over the heavy 18" alloy rim option ...and that's unsprung weight. The weight of a 205/55R17 tyre is also probably lighter than a wider 225/45R18 tyre. Not to mention the much improved ride from the higher sidewalled 17" tyre, and improved mpg due to less drag and less weight.

 

In sales brochures you might have come across the misleading term "light alloy wheels". This is often incorrect, as steel rims are usually lighter than alloy rims. The reason being that although it's possible to make an alloy rim light if expensive alloys are used such as magnesium, usually manufacturers use cheap, weak, and heavy cast aluminium. Because cast aluminium is weak, a lot of material is needed to get sufficient strength...and that's where the weight problem comes. They look great and shiny in the showroom, but are nothing compared to the quality of the alloy rims you might find on a Porsche/Ferrari, etc. Manufacturers love fitting these cheap, shiny cast aluminium wheels to their cars because it helps them increase the price of the cars. It's a bit like fake jewellery, they may be shiny but definitely not quality.

If you want to do things "by the book" then rim and tyre specifications are provided in...

1. the CoC (Certificate of Conformity) which your dealer is obliged to provide you with when you pick up your new car (https://www.gov.uk/guidance/certificate-of-conformity-for-new-vehicles). See item 35 ("Fitted tyres/rims...") and item 52 ("Remarks") or

2. the workshop manual "Wheels, Tyres", section "14.3 Permitted wheel / tire combinations according to WLTP" which can be downloaded from here https://cardiagn.com/2020-2022-skoda-octavia-mk4-workshop-manual-wiring-owners/

I've currently got aftermarket rims for my winter tyres and I've had aftermarket rims of different brands in the past. The wheel bolts have always had the same dimensions as the original ones and I've never had a problem finding aftermarket rims with the correct centre bore. There's been times when I wanted a specific rim which was not available in the correct centre bore. I've then used spigot rings (even plastic ones) without any problems.

 

I've had no issues with the quality of the aftermarket rims I'm using and have used in the past. I'm particularly pleased with the price and the mulitude of designs of aftermarket rims to choose from compared to Skoda original rims.

It sounds like you might have been using the wrong wheel bolts for your aftermarket rims.

 

It's a common mistake to use wheel bolts with ball shaped seats in alloy rims designed for (and machined for) cone shaped wheel bolts seats.

 

Most aftermarket rims use cone shaped wheel bolt seats, whereas VAG uses ball shaped wheel bolt seats.

 

Cone is used interchangeable with conical, ie. different term for the same thing.

 

Ball shaped is used interchangeably with sphere shaped and spherical.

 

Maybe you have chosen your aftermarket rims carefully, and/or got lucky...but it's not the norm for aftermarket alloy rims to have ball shaped seats for the wheel bolts.

 

Aftermarket alloy rims might even need longer/shorter wheel bolts than standard.

 

VAG has a huge range of alloy rims that have been fitted to various models over the years. If you can find something close from another model to the standard specifications, there's often a lot of choice and secondhand availability on ebay, etc. If you damage one of your alloy rims and need a single replacement, it's often easier to find a single VAG rim. It's easier to search for VAG rims, as they all use unique OEM part numbers. I wouldn't fancy searching for a single replacement for an aftermarket rim, you might get the response..."oh that was so last year", or "we can only give you a good price if you buy a set of four", etc.

My Dezent wheels came with conical bolts so I use them. When I switch to my summer wheels, i.e. the ones that the car came with, I'm use the originally provided bolts. Don't see an issue with that...

Skoda actually produce a catalogue (with pictures) of the selection of wheels, if you buy the smaller wheel sizes tyres are usually cheaper (smallest size won’t fit the more powerful versions with bigger brakes)

 

note Octavia mk 3 and mk4 are listed as Octavia III and IV
