Sorry Sid, I´ll have to correct you on this one - As long as theres not more than a 3% difference in the overall diameter of the wheels you can run whatever wheel tyre combo you want, as long as the tyres are rated equal or better than what the paperwork says.
Ive got a megane coupe - 14" or 15" as standard, and I run 17"s - it passes the ITV every year.
There is an APP called "equivilancias" - you put in your standard size and it tells you which size you can have on the car without issue. I think Im ok with 18" or 19" as well...
