I have Suzuki Wegon-R Japanese 2012 model. I installed wider tires with new alloy rims to get a better road grip. But after installation, I have found that the mileage has dropped from 14.5km/l to 12km/l in city and 17.5km/l to 15.5km/l in highway. Now I am thinking to go back because this is a big loss. Please also let me inform other bad effects of wider tires and also guide me the right type of tires and rim should I use for this Car.
Wider tyre = bigger turning radius,drop in mileage,hard suspention (kei cars),stress on engine,load on EPs,error in speedometer reading
