hey , Im thinking of getting some new set of tires for my 2003 Jaguar X Type.
I came across some Niche wheels that interested me.
My question is, what is the biggest wheel size and tire size i can go with stock suspension?
I saw in another thread that the biggest wheel size you could go was 18 in but yet again in another thread i saw that someone put that you could go as far as 20. And i am wondering , what if i when with 20 in about what is the tire size i have to get in order for it not to be rubbing.

Thanks in advance.
