[QUOTE="Mun, post: 447052, member: 17916"] Paid a visit to MPS two days ago. I have noticed uneven tyre wear on my bridgestone. Strangely, its wearing on both inner and out sides of the tyre. Centre part is not wearing similarly. Few weeks ago got a tyre pressure warning, and surprised to check the punctured tyre has no pressure at all, unlike previous case of only 25% down. When we took the tyre out I was shocked to see the inner part ribbed off about 4 inches. Cant figure out what caused that. Also noticed inner wear was about 20% and outer 30%. Didn't gave much thought so changed the rear to Pirellis PZero. So at MPS Manji pointed the front is wearing 30% on the inner and outside and 50% in the centre. He told me to put up more pressure but i told him that I kept the pressure checked regularly according to the recommended pressure 270kPa back and 240kPA front. (18' MSport btw) Theoretically, Manji is right. Tyre under low pressure can wear on the outside as the centre surface buckles inwards, where the walls taking the weight. But i'm suspecting the stiffness of the bridgestone walls has something to do with it. Then I also considered maybe those tyre pump at the station may not alway give accurate pressure. Initially, most of the time I've countercheck with my pressure gauge. I remembered once the pump was 10kPa off. And lately I seldom counter checked and maybe the pump has not been re-calibrate. Anyway, Drove to Kuala Terengganu very early yesterday morning for a meeting and it was raining on the Karak hiway. Had some scary moment with standing water and a small truck veering into my lane. The front pair is not doing very well, and I need to replace this very soon, especially before raya balik kampung trip. On the way back it was dry. Cornering and turning in was a lot better. Manji did a very good job. So good, I back just in time to buy my own food and break fast at home ( Coz my wife wasn't expecting me back so soon) [/QUOTE]
