At the moment I can't not say anything, but, I think about 0.5 liters more than 17's ones in city mode. But very impressive improvement in stability and conctat

Hi everybody!

I'm from Spain but actually living in Belgium, nice to present my 2015 i40 SW 1.6 Gdi with new Summer mode wheels. 20" 9j ET45 with 245/30/r20 Vredestein Ultrac Sassanta. I'm very glad with this configuration. I had 205/50/17 and I'm not compromising the comfort with this configuration at all, also with the family concept of the car and my personal use.
