18" and yes they look smaller.. Don't know why? May be black color or the design... Same Dunlops offered.
Good part is addition of rear wheel disc brakes on the already superb fortuner brakes.
Suspension is expected to be bouncy in contrast thai counterparts where steering is sharp & suspension gets stiffer & sportier with TRd.. Agri Autos is also adding a stabilizing bar so TRD variants will somehow handle better due to reduced body roll & traction control , brake better and look better.
