Suggest me the measurements of the Rear tyres ! Am NOOB about this. The stock rear tyre is not so wide does't look good.
Stock Size will be best for your bike. because wide tyre will take down your mileage and may also disbalance your bike. So get Michelin or Conti as your current size tyre. I am suggesting these companies because they are soft compound tyre and will reduce friction and will increase rolling distance. Hence increase i. mileage and stability.
