This is gold! There are a lot of nice models to .... go crazy about 🤪 in anycase I saw there are 5mm spacers available, worse case scenario ....

hello, i bought some 235 R18 winter wheels and they just barely fit 4 in the trunk standing next to each other [estate].

i'm just curious if also four 245 R18/R19 wheels would fit?

(and what about liftback?)

well a 245 tyre is 10mm wider than a 235 tyre.......so u would b looking at extra 40mm (4 cm) in total.
as for the height clearance, that would depend on the tyre profile, i.e 35, 40, 45 etc etc., in combination with rim size, i.e. R18 or R19.

 

without looking at the exact specs, the 245 tyres, R18 or R19, will definitely require more space than ur 235 R18 tyres.

 

245 40/R19, ET35*9.5J, this is my current data, it is almost flush with the body, it feels pretty good.

those rims look nice 😍

 

i'm also running 245/40R19 tyres, on Rotiform 19x8.5 ET35.  sits nicely with the body too 🙂

Hi.

 

Sorry for thread revival but I was wondering if you guys could advise?

I've ordered Damina alloys this morning before I realised that there could be issues (seller assured me there won't be any but they always do.) 

The alloys are DAMINA PERFORMANCE DM18 8,5x20 5x112 ET30 Bronze Matt

So my first question is: Is ET 30 x 8.5J still acceptable for Superb 2018 2.0TDI?

If so, what tyres can I use?

Ideally I'd go for 245 but I'm cautious this could be a no go.

Does anyone have 8,5x20 ET30 Rims installed and if so what tyres do you have?

 

 

Thank you very much for help

This is how they should look like 

Hi all.

I have these 8,5x20 5x112 ET30 Bronze with 235/35/20 tyres on them (on a picture) They are nice, I really like them but I think I'd like to go bigger so I would like to ask you guys who obviously know more if there is any chance for me to fit 9x21 5x120 ET30 allloys with 245/35 R21 tyres on them?
These would go wider from 8.5 to 9, tyres from 235 to 245, same ET30 and obviously an ich bigger wheels with the same tyre profile of 35. Is that possible on prre-facelift MK3?

Thank you everyone

As you can see in the chart below, the 245/35R21 tyre size has an outside diameter between 5.1% and 6.1% bigger than the standard tyre sizes.

 

If you want a 9" rim width, perhaps look at something like 255/30R21 fitted to a 9Jx21 ET42...although that might rub on the inside. Fitting this tyre size to a narrower 8.5Jx21 ET40 rim would free up an extra 5mm on the inside reducing the chance of rubbing on the inside. You get an extra 2mm on inside clearance because of the different offset, ie. ET40 instead of ET42...and an extra 3mm of inside clearance because of the 0.5" narrower rim, which squeezes the sidewalls together more.

 

Note that there's always a risk of rubbing or the tyre sticking too far out when you start pushing the limits, and it's possible that even a 255/30R21 fitted to a 8.5Jx21 ET40 rim could rub or stick out from the wheelarch.

The below VISION alloy rims from the Skoda Enyaq are claimed to weigh 15.3kg each, which isn't much more than some of the standard 19" alloy rims on the Superb MK3.

As you can see in the chart below, a 255/30R21 tyre fitted to an 8.5J rim is 18mm wider than the standard 235/45R18 tyre fitted to an 8J rim, ie. 9mm more each side. As an ET40 offset moves the centre of the tyre 4mm outward compared to an ET44 offset, the tyre is very unlikely to rub on the inside...except that extra consideration needs to be given to the clearance on the front when the steering wheel is turned to full lock...because of the extra outside diameter of the 255/30R21 sized tyre compared to the standard 235/40R19 sized tyre. However, the extra radius of the 255/30R21 tyre compared to the 235/40R19 tyre is only 7.9mm...so I doubt the 255/30R21 tyre fitted to a 8.5Jx21 ET40 rim would rub on the inside.

 

Considering some owners have fitted 15mm spacers to their 235/40R19 tyres on standard 8Jx19 ET44 rims...I doubt 255/30R21 tyres fitted to 8.5Jx21 ET40 rims would rub on the outside either because the extra outside clearance needed is only 13mm, and the owners who have fitted 15mm spacers have proved that their is at least an extra 15mm of clearance on the outside.

i have question if some PCD 5x112 rims from other cars like audi, bmw, mercedes will fit on superb ?

what to look for ?

of course i need to watch for Einpresstiefe

but what about center bore size for example?

thanks

 

I have a set of Audi badged whees with winter tyres they currently have alloy spigot rings fitted for use on Škoda 57.1mm vice Audi 66mm.

 

See here for details:

 

 

Basically, the 3 main aspects of wheel figment will be PCD, centre bore and offset. PCD is the number of bolts and the diameter of an imaginary circle that would run through the centre of the bolt holes. Centre bore is the big hole in the middle and offset is the way the wheel sits in/out from the car. 
Basically, look for the standard specs and match to that. You can be a ‘bit’ flexible with offset (which will be a range anyway) but too far in and the wheel rubs on the inner wheel lining (noting full lock for the fronts) or suspension strut and too far out and they’ll rub in the wheel arches when the suspension compresses.

 

I’m sure there is plenty more to it but that’s the basics.

Pretty good places to start

These are lovely. Very BMW HRE-esque

Update on this, I've done already almost 3k km on the new winter tires, car is very different from the summer 19s ....

A bit more rolling here and there, but nothing the poor damping of the OE DCC can minimize ... braking is more "spongy", less direct feeling, before it was tighter, but is not a problem, actually lets you modulate better. Easier on the steering and less tramlining than before.

Comfort and absorption of road irregularities has improved galactically, is impossible to compare. Mind also my summers are +3 years already, so a bit old and probably not in the best shape. Nevertheless ...

Road noise does not seem to have changed, must say these are winters and is winter so difficult to compare.

Car stance is less aggressive and sporty looking, but these are looks, and cars are meant to be more driven than looked at 😜

 

I now will surely downgrade to 18s for next season, I was set on the Antares model, but after seeing the brochure linked above I see there is the option of the Trinity on 18s, which is a design i really like.

They do not come for the Superb, but are on 7x18 ET43 with 235/55 for the Kodiaq, and 7x18 ET45 with 215/50 or 225/50 for the Karoq.

Superb is listed with a larger rim at 8x18 ET44 with 235/45.

I think 235/55 are too big of a fit and the rims are 7 and not 8 ... would 225/45 or 225/50 be reasonable alternatives? I know is early .... we got months ahead!

Thanks!😊

 

Well, on the above post I said 'there were months ahead' now the months are gone ... time to start add another expense and think summer rubber.

I am set on putting 18s, and I like the fact now the 'Trinity' model is available, albeit from other models, not Superb. Will they fit?

I would really like polished finish, like the 19s that came with the car ... i think is the "brushed" finish, called.

 

This is from Karoq, comes in 7Jx18 ET45.

https://www.skoda-parts.com/spare-part/565071498d8z8-aluminium-rim-18-trinity-skoda-30306.html

 

This model 'Turini' I do not know where it comes from, but I am afraid ET51 pushes more in although is 7.5J as opposed to the other ones, so it should compensate.

https://www.kopacek.com/skoda/wheels/turini-18-original-skoda-autoas-4pcs-set-of-rims

I also think is only painted and not brushed like the ones above. Pity there are no better photos, will have to look at adverts hoping some car has them fitted and see how they look in reality.

 

Opinions, thoughts?

Will be able to fit 225 or 235 in 50 ? I know some mount 245/45 but this looks too wide for my taste ...

 

Thanks for the help
🙂

For non-standard 18" wheels on the Superb MK3, I would look at 225/50R18 fitted to 7Jx18 ET43 rims (from the Kodiaq MK1).

 

The Kodiaq MK1 normally uses 235/55R18 on its 7Jx18 ET43 rims, but the outside diameter of these is too big for the Superb MK3.

 

I wouldn't be looking at an offset more than ET43 with 225 tyres on the Superb MK3, unless you like your wheels to look sunken in the wheelarches.

 

Edited 20 February, 20251 yr by Carlston

Thanks to clarify that 225/50 would fit, I've used same aspect ration but on 17s on my previous Ur-S and it was very decent compromise.

I am not a fan of very "tucked" wheels, but I do not like them too much out either, they tend to dirty the car a lot.

 

Now the question is that the Kodiaq rim is 'silver' on ET43 vs the 'brilliant silver' on ET45 of the Karoq ... mumble mumble ...those 2mm might be too much 🤔

The Skoda accessory catalogue lists silver TRINITY alloy rims with the same 8Z8 colour code for both the Kodiaq MK1 and Karoq...as shown in the two links below. The Skoda parts catalogue describes colour code 8Z8 as Diamond Silver. As both alloy rims have the same 8Z8 colour code, they will both be the same colour.

245/45R18 on standard 8Jx18 ET44 rims is a good choice for looks and comfort. 245/45R18 is a more popular and economical size than 245/40R19. 245/45 on 8J rims better protect the rims from kerbing damage than 245/40 on 8.5J rims.

Hi, I'm looking at changing to some 18's and your comment is really interesting. I had a look a 245 prices after reading it and they are way cheaper than 235 and 225 tyres here in Australia.

Also I'm really interested in your comment re kerbing damage but I'm not too sure what the j means in the 8inch size.

The rims I'm looking at are ET42 and not 44. Do you think the 245/45/18 are going to be ok on 42s?

For reference I'm looking at this package:

Compared to a 245/45R18 fitted to an 8" wide rim, a 225/50R18 fitted to a 7" wide rim would give far more protection from kerbing damage because the tyre's sidewalls bulge out about twice as much...as shown in the chart below.

Amount tyre sidewalls bulge out each side from rim

245/45 fitted to 8" wide rim 7.9mm

225/50 fitted to 7" wide rim 15.6mm

The reason that the difference is so big, is because the actual width of a 245/45 fitted to an 8" rim width is 243mm, and the actual width of a 225/50 fitted to a 7" rim width is 233mm, ie. the 245/45 is only 10mm wider not 20mm wider...which you might expect. See the chart below. What is happening, it that the sidewalls on tyres with an aspect ratio less than 50 don't tend to bulge out much, but once you get to tyres with an aspect ratio of at least 50 the tyre's sidewalls tend to bulge out a lot more. Hence, if you want good rim protection from kerbing damage choose tyres with an aspect ratio of at least 50 and fit them to relatively narrow rims or at least a rim that isn't wider than normal for that particular tyre size.

Actual width of inflated tyre measured from sidewall to sidewall at the widest point

245/45 fitted to 8" rim width 243mm

225/50 fitted to 7" rim width 233mm

As you can see in the ETRTO chart below, a 7" rim width is the standard rim width for a 225/50 tyre and an 8" rim width is the standard rim width for a 245/45 tyre...hence both 7.0 and 8.0 are highlighted.

ETRTO approved rim widths for passenger car tyres

225/50 6.0-7.0-8.0

245/45 7.5-8.0-9.0

Thank you so much for such a detailed reply. Really helpful and has given me something to think about! I'll report back next week once the wheels and tyres are fitted.

This is exactly the setup I went with on my new rims.  Still could have gone a little more aggressive, around the ET35-ET33 mark, but as I tow a jetski I didn't want rubbing issues (I'm on Eibachs) on the rears so stuck with the above.  I might look at putting some 5mm spacers on the fronts.

Sorry, could you please tell me exactly which wheels you have fitted in the photo and the exact size? Thank you!

Hi, bit of an older topic, but I’d like to ask.

I’m planning to get 19x8.5 rims. The recommended tire size for that width is 245/35 R19. I have a 2017 Škoda Superb 3 Sportline, which is already lowered from the factory by about 15 mm. I’m planning to install the Eibach -30 mm spring kit, so the car would be lowered by an additional ~15 mm (around -30 mm total compared to standard height).

Does anyone run this setup? Is it safe to use, and will it help me avoid rubbing?
