If you want a smaller wheel/tire please consider this. A 26×3.0 Plus tire is the same height as a 27.5×2.5 tire. A 26×2.8 Plus tire is the same height as a 27.5×2.4 tire. Personally, I recommend a 27.5×2.6 tires on i30 rims because they perform most like 29×2.4 tires in terms of traction and flotation.
