Camber and alignment out will only make the tyre worn either side. tyre too much air or pressure will worn in the middle part. if both sides worn equally, then it should be low pressure. Front tyre worn faster because of the engine weight, front wheel drive and steering of tyres. front tyre pressure should be greater than the rear. Never trust the tyre pressure sticker on your car or booklet. different tyre brand different pressure even though same size.

QUOTE(advocado @ Nov 20 2012, 10:02 PM) stock is 15 195 60R right? Too long cannot remember right now try to run your car onto some sand dust road, then stop yr car and have a look on your tyre. it will give you a lot of info when your tyre stick with the sand dust.Added on November 20, 2012, 10:03 pmSo how you judge whether need more air or too much air? Do you pump until the bottom of tire to as flat as other areas or "bump out" a bit, coz usually the weight load is at the bottom of the tyre. |

QUOTE(advocado @ Nov 20 2012, 10:13 PM) Usually rotate cost you how much, last time wanna rotate but forgot, also i hear need to balance camber alignment this and that probably cost rm50... Rotating car tyres doesn't need to do alignment unless you went into a big hole that causes the alignment out. Tyre balancing is needed when tyre is off from the rim.I don't U-turn at 60 la. So if cornering tayar no screech means all is good? i only do 60 at those turn like U shape turns but not U-Turn la. Tyre no screech.

So i forgot about rotating it. less air means more friction, more grip and not bumpy but wobble.Also the tyre pressure how the tyre look is important? I mean you pump until tyre is all flat or let the bottom bump out abit due to weight on the bottom? I prefer abit less air because too much make the tyre bumpy and less grip. Added on November 20, 2012, 10:33 pmI'll always change 4 tyres together and all my tyres last for 50K to 55K KM. This post has been edited by ToyotaKaki: Nov 20 2012, 10:33 PM |

QUOTE(advocado @ Nov 20 2012, 10:38 PM) So rotate also no need weight balancing, just new tyres need weight balancing right? read the tyre wall. it indicate the tyre max pressure.So as long as the wheels are straight there is no harm doing rotation between front & rear, but better swap left to left right to right right? I always scare pump too much air until the tyre like wanna explode. |
