cheap and incorrectly selected rims cause the steering to get harder, i have 13" alloys in my khyber, they have a retro look but they are lightweight than the genuine spare steely and are of really high quality, thats why i dont upgrade to newer rims cause chinese ones with looks are of really cheap quality, so i have began to like what i have and chinese rims look more "paindu" to me. i steer it with one hand easily all the time. and i dont have power steering installed.p.s. i'm the skinniest boy in my class, i'm 5'10 and 55 kg.
