Q. I wants to change my aviators front &rear wheels with 14 inch wheels for front &12 inches with rear?

You may go for a wider tyre but upsizing the size of a tyre is increasingly becoming an obsession with people to create an added visual appeal to their scooter. Moreover, It is advisable to go for an upgrade anywhere between the 3% margin for better performance and handling, increased grip and creating a visual appeal. Do take note that upsizing the wheels and tyres may decrease the fuel efficiency of the scooter and may result in a speedometer error on the scooter if upsizing is not correct. So, we would not recommend you to go for the scooter size which you want to install in your scooter for better performance. Moreover, for the same, we would suggest you to exchange a word with the authorized service center as they will assist you better with this concern. You can find the service centers here.
