Q. Can I enhance the sizes of tyres in my old jawa 250 bike

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 bike. 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 bike and may result in a speedometer error on the bike if upsizing is not correct.
