Good day, group members,

I need some advice. I’m planning to purchase new rims for my Škoda Superb 2017 Sportline.

I’ve decided on CVR1 rims, which I really like, but I’m unsure about the best size and tire setup. What I’m aiming for is a MID to DEEP concave look with a sporty appearance.

Here are the TÜV-approved options available for my car:

Option 1 – 20” (MID Concave)
• 20x9
• Tires: 235/35 or 245/35
• Concave: MID

Option 2 – 19” (DEEP Concave)
• 19x9
• Tires: 225/40 or 235/40
• Concave: DEEP

After some research, my current preference is 20x9 MID concave, but I’m unsure about the tire size. I’m leaning towards 245/35 mainly for better rim protection, but I’m not 100% certain if that’s the best choice for the Superb.

I’m aware there’s also a Performance concave option, but it doesn’t give the visual depth I’m looking for. While it offers more sizing options, I’d prefer to avoid the Performance concave if possible, as the concave look is important to me.

My main goal is visual impact and a sporty look, not track performance.

Currently, I’m running stock VEGA R19 wheels for summer, but they’re scratched and damaged, so they need replacing anyway.

Tires will be Michelin or Continental.

I’d really appreciate your opinions on:

• 19” vs 20” for the Superb

• Best tire size for rim protection and stance

• What setup looks best without ruining comfort too much

Any suggestions are welcome. Thanks in advance! 🙌

Firstly - forget about comfort. You're sacrificing that for exterior aesthetics.

The standard Superb 19s are 19x8 and that runs a 235 as standard. You can switch to 245 but I did and they look bulgey and I don't like the aesthetic.

Aftermarket 8.5 wide usually get mated to a 245 so 235 on a 9" wide is going to look very stretched euro I would imagine. Which means if you want any rim protection, that needs to be built into the carcass than on size of tyre alone.

It could work. McLaren 19x8 came with 225 as standard and the 20x10" rear came with 285. Slimmer fit than the Skoda.

Personally I'd say 245 on a 9" would look slim. If they're square setup (all wheels same size) then go to Will They Fit, put in the standard sizes and look at how any changes you would consider would change the poke/ride height/speedo accuracy.

Standard is 19x8, ET44, 235/40 tyre.

Below is a comparison of 20×9 ET35 with 245/35 against the stock setup.

However, below are all the wheel specifications I can run, regardless of whether they are Performance, Mid, or Deep concave.

Which combination would you choose?
To be honest, I prefer a sporty look—I don’t like tires with a very tall sidewall. On the other hand, I’ve seen setups like 235/40 R19 where the sidewall looked huge… but I believe that also depends on the wheel width, right?

19×8 ET36/40 – 225/40, 235/40, 245/35, 245/40

19×8.5 ET35 – 225/40, 235/40, 245/35, 245/40, 255/35
ET45 – 225/40

19×9 ET40 – 225/40, 235/40

19×9.5 ET35 – 235/40

20×8 ET36 – 235/35, 245/35

20×8.5 ET35 – 235/35, 245/35, 255/30
ET45 – 235/35

20×9 ET35 – 235/35, 245/35

I'm running 19x8.5 ET35 with 245/40r19 tyres.

Yep width of the tire sits differently depending on the width of the wheel. You can probably fit a 235 on a 7.5, 8, 8.5, 9 and will look very different in all of them. Optimal tyre pressures will vary too as I’m sure extreme euro-stretched tyres need higher pressures to make sure they stay on the rim.

Looking through those options my personal preference is to go full dish; I’m not convinced by the semi-dish effect of the other ones but that’s just my viewpoint - you go with what you want.

Looking at JRRS’ car, 245 on an 8.5 is basically the same ratio as 235 on an 8 so that’ll give you that neutral straight up side wall. Sticking the 245 on the 9” would be a little stretched. But it’s the second number that determines the height of the sidewall (you mentioned huge sidewall).

Couple of pics to demonstrate the sidewall look.

Another thing to be conscious of - the ET on those means they will sit out 20mm more than standard.

The standard wheels on the Superb definitely need more poke (sitting out from the car) but those 20x9 would be the same as sticking on 21mm spacers which would be very noticeable and possibly cause rubbing on the wheel arch edge if you have any lowered suspension.

I’m running 12mm spacers all round but my new summer wheels will be 11.5mm lower offset so I can remove the spacers an have the same outside profile; it’s subtle but a much better look.

You’ve got a balancing act with the additional width - not going out too far that it looks like a tractor, but not sacrificing poke and end up getting rubbing on a wheel arch liner etc.

Not gonna plan to lower car or add any spacer if I use ET 35. My car is now fully stock did not changed anything there. If there is a TUV for it I believe should be ok.

I didn’t advise a spacer with a lower offset - jus to be conscious of fit.

What does TUV provide aside from build quality?

m not exactly sure what you mean, but the TÜV document contains wheel dimensions and the approved tire variations suitable for those wheels and for a specific car model. This is used for registration in the vehicle’s technical certificate, at least here in Slovakia.

After that, there are usually just some notes, such as that the car should not be excessively lowered, otherwise the tire could rub against the fender. Basically, if everything is in the original factory condition, there is no problem; if it is not, fender modifications or other adjustments are required, etc.

Fair enough - I don’t think we rely on that sort of thing in UK. There isn’t a relevant governing body that would certificate, just down to the manufacturer and owner to research as far as I know.

Good you have that reliance 👍🏼
