Sorry to grave dig this one, but I've just become a Kodiaq owner (we are now exclusively Skodalorians with a Yeti and a Kodiaq), and its Pirelli Scorpion Verde Seal tyres are kaput. They are 235/45 R20 (it's a 140TDI Sportline model - 2018, Australia).
I too don't have much to choose from in that particular size, and the choices I do have are expensive. Replacement Pirellis of the same type are nearly AU$1800 for 4. Whereas some Pirelli Scorpion Verde All Season in 245/45 R20 are $1100. It seems folk here in this thread have successfully installed that size. According to calculations it only affects the speedometer by 1km/h up to 120 at which point it's out by 2 (going by dash speedo of course which only uses integers).
So before I go and order these tyres, I guess my question is - would that tyre size have always been rare when Skoda chose it? Is there a reason they didn't just use 245's? I have no idea the engineering process that goes into such decisions, but given our 2010 Yeti has been such a solid reliable care I'm cautious about doing something Skoda didn't think of doing from the factory.
Thanks in advance.
