Size 110/90-16 tires
From Ninja250Wiki
Regardless of tire manufacturer, you must RAISE THE FRONT FENDER if you are installing a 110/90-16 front tire. You don't want bad things to happen.
110/90-16 GT501
110/90-16 BT45
This is especially applicable to Dunlop GT501 tires, as Dunlop doesn't sell size 100/90-16 in the US. Other manufacturers generally have the smaller size available, and you would be better off going with the 100/90-16 in that case (such as Sport Demons).
