Hey Leuts, have a question like that! I had to mature on my Corsa 1.0 BJ 2000 145 r 13 on steel rims before. Now I have missed the Corsa some new shoes… 205 R 16 Aluflegen. Since I have consumed the Corsa on average on 100 KM 4 liters more than usual and the performance is also gone, otherwise he drove on the highway 165 top now comes only about 130 kmH with toil! Now my question can it lie on the tires? because the much bigger and wider sin d ? Thank you
