- My Plus 4 Sport has 205/65R15 tyres. No grounding problems, but luckily there aren't a huge number of road humps around here!

It must be fitted with the standard Roadster rims, which is an option, the standard tyre fitment on the Roadster was 205/60 R15. Fitting 195/65 tyres takes the ride height up to about 15mm more than the standard Plus 4.
