I have 18" rims that come with M Sport package. It's a staggered setup. What I was saying was that this 18" look bit small on the car. So, I was thinking maybe I should have opted for 19" but then what I found from my calculation was that 225/40 19 & 255/35 19 are actually slightly smaller in diameter than 225/45 18 & 255/40 18. So, the rims would look bigger since they are 19s but the overall diameter (with tyres on) they would be actually smaller than the 18" due to lower profile tyres. So, going 19" with original tyre profile doesn't seem to help get the bigger wheels. So, was wondering if 245/40 19 and 275/35 19 would fit X1 without any issue for my future mods hopefully
