i had a problem with my front wheels... my tires are balding on the inside and outside but NOT in the middle, i do not do burnouts, pretty much ever, and the tires are only a year old, they are nankangs summer only tires and i only use them april- november. inflation was fine, so i brought it to a tire shop thinking i needed an alignment and maybe a bearing since it pulled to the right. and they told me my rack and pinion is shot? someone tell me how this happens, and if they are being honest or just trying to get money out of me!
