各位兄弟姐妹，本人在做一个关于轮胎的survey，望大家给点意见，积极参与！ 

1. What do you know about UNICORN TIRE BRAND? Have you ever use any products of this brand? 2. What brand do you prefer when you need to choose a tire? BR GOODRICH, CONTINENTAL, DUNLOP, FIERCE, GENERAL, GOODYEAR, HANKOOK, MICHELIN, MOTOMASTER, PIRELLI, UNIROYAL? 3. What factor you care the most when you choose tires? Price? Quality? Durability? or something else? 4. What kind of after sale service do you expect tire providers to do? That is all my questions. Please say something about them, anything ok. Thanks.
