I have been experiencing a irritating humming noise front front tires from quite sometime in ny Punto mjd. The sound came just after I switched to MRF zlos. Got tires changed from crappy jks to ZLOs just after 200kms. Everything was as per reviews, zlo is really a very good tire. Grippy, noiseless and really complimented the handling and ride quality of Punto. But there is a humming noise, just like a busted/faulty bearing which comes at around 30kmph till 45kmph and after that is gradually decreases to a great extent. First i thought bearing has gone kaput or its some other problem with the car itself. Showed it to Satluj Motors (mandi, himachal). As expected they showed least interest and never bothered to check anythin properly. Then after using for atleast 5500kms, took car to Banarasi Dass automobiles, panchkula. They addresses the problem quite well and it took them just 15mins to find the actual fault. It was the tires. To confirm, made them change all four tires with another punto's tires and problem was solved. It was all because of zLOs. There is a member here and on teambhp, who are facing exactly same problem. So guys, before opting for ZLOs, do check if its making humming noise or not. Other members using ZLO please share your experience with zlos. Anyone else also who is facing the same problem ?
