Please confirm if they are 225/45 or 225/50. I'm pretty sure I remember the Superb coming with 225/50 R17 tyres on the V6 model. Do check the drivers door frame or fuel lid cover where tyre pressures are mentioned. They also mention different tyre sizes. See if for 17" 225/45 or whether 225/50 is mentioned?

As long as the OD of the tyres is the same it's ok. Different OD tyres on the driving wheels may be problematic IMHO

The V6 models came with 225/45 R17 as OE fitment (all 5 tyres).

I hope your car is the second gen Superb. Unless it is the V6, the spare tyre would be 205/55 R16, not 205/55 R17(improper size).225/45 R17 is also a proper upgrade sizes for both second gen Superb and Laura. Stock tyres on the 16" Lauras and Superbs were 205/55 R16.

205/55 R16, 225/50 R16, 225/45 R17 are all closely matched & accepted sizes for the tyres and thus you should have no trouble in maintaining the first size as a spare tyre.

Thanks Avinash. Yes you are correct, my last two posts are wrong and I am not able to find the edit button.

my 17 inches are 225/45 R17
my spare is 205/55 R16

Besides, I took the car to Ignite and he said, one of my alloys have a small damage, which could seep the air outside. He suggested to change all the alloys and the tyre. I am now finding for options, but I am planning to keep the alloys as the damage is not that bad afaik.

He did have a 5 set of BBS 235/40 R18, which he had removed from a Laura. He is quoting 80k for it including the tyres (which are 6 years old). Still in dilemma on this choice. Even if I get new tyres, it might cost me minimum of 45-50k and this deal sounds good with the BBS and the tyre has another 10k kms left on it. What do you recommend?

The correct size in 18" is 225/40 R18, though 235/40 R18 is also acceptable.

Personally I don't recommend the 18" on a Superb. You have to run quite a low profile and will require extra caution always to not damage the rim or tyre. I don't see any benefit apart from cosmetic ones. BBS alloys would shed some unsprung weight, but likely that the 17" wheels of Skoda weighs the same as an 18" from BBS. Stick to 17" is my recommendation.

I am not sure which brand of tyres you have on the car currently. There are good number of top spec tyres in 225/45 R17 size (Yoko advan sport, Michelin Pilot Sport 3, Hankook S1 Evo 2 K117 etc). They can make a significant difference if current tyres are regular ones.

Having a 6 year old tyre, irrespective of tread depth left is not advisable. Natural aging would have made the rubber loose its qualities of grip, load/heat resistance etc. So buying those BBS rims will require new tyres also.

Why not replace only the single damaged alloy? Rather buying used 18" rims for 80k, you can have new 17" from other reputed brands
