road tire performs well on urban roads, and it has lower tyre noise, so it's quietest. These tires and inner tubes are fit for Zero 10X/Speedual, if you install it on Zero/ 10, the rear wheel is , but there would be a slight friction between the tire and fender when you install it on the front wheel, it's not a big problem, just a little driving noise. These tires are fit for many scooters, please check the tires of your scooter, if the inner diameter is 150mm, and the size is 10x 2.5/10x 2, based on my experience, they are universal, such as for Inokim OX/ etc. But I have to inform you, due to the narrow fenders or narrow swing , there is not enough space to accommodate such a wider tire, although the size of your scooter's hub is fit for the tire, such as for Dualtron 1/2, Speedway 1/2/3/4, Inokim quick 1/2/3, but in fact all of them are incompatible Installation & adjustment of the tire requires high hands-on abilityThe shock absorption ability of pneumatic tire is better than solid tire obviously, but if you don't pump in air regularly, the inner tube would be crushed by outer tire, so make sure the inner tube pump air amply regularly. : 80/65-6 s: 10 inch inner and outer tires ur: Material:rubber Size:Outer diameter: 25 cmInner diameter: 15 cmWidth: 8.4 cmPackage Contents:1x 80/65-6 inner and outer tires the above package content, products are not included.
