Hello to all, since yesterday I finally got rid of the old 155/70R13-steel rims all-weather tires by 195/50R15-wheels also replaced all-weather tires. Now I have three problems and ask for help Seat Arosa 1.0 MPI AUC end 2003 1- Acceleration: I notice at once that the car does not accelerate at all – as if I had a gear less . Usually it was like this at 2000 U/min: -First gear: up to 1–20 km/h -Second gear: 20–30 km/h -Third gear: 30–50 km/h -Fourth gear: 60–75 km/h But now I drive most of the time at 44 km/h in the fourth gear at 2000 U/min :\ When I speed up I turn almost at 3500–4000 U/min but still it feels very sluggish to me. Can bigger wheels really make such a big difference? They like almost as much as the old … Ps. On the highway without big incline I can’t be recorded with a slow acceleration of about 140 km.
