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. <_< Carlos from Spain.
