So I am thoroughly confused....
What should a 2011 Plus 4 be running? Mine has I believe the original factory fitted tyres... which are avon 205/65 r15. When I look at a tyre company's website based on my reg it says they should be 195/65 r15. The handbook supplied is for a later car... it has 4 tyre sizes none of which is what is fitted...
I would say the tyres already fitted are the right ones. 185 are for narrow bodied +4.
Most +4 have the 205.
