Tyre Size For Tdi 110hp.

[acme2000]

I just bought a Ford Galaxy TDI 110, and it needs to change the tyres. The originals are 195/65R15, and optional 205/60R15 and 215/60R15. I am going to buy the 205 size, but first I want to know your opinion about this matter. My questions are:

is a good option changing the size?

Will the Ford go slower with this tyres?

More fuel consumption? How much?

What model do you recommend?

Thanks to everybody.
