Hi All,
I have a set of WANLI 235x45x17 on tickford rims on my S1 AU Fairmont Ghia. The problem is the front tyres look almost new....but the back tyres are wearing in the centre out quite quickly!!!! I have 40psi all round & don't drive the car too hard. I drive mostly highway everyday for work. The tyres are lucky to have 10-15K's on them if that... Is anyone else experiencing the same problem??? Cheers  : |

Do you have an IRS rear? It could be that.
How hard do you drive?

the only reason tyres wear the centres out like that is if they're over inflated and/or run at high speed constantly. In saying that, 100kph isn't usually enough on it's own to cause the wear. I had a mate with a Patrol and wide wheels and he would constantly hammer the thing at 130-140kph going fishing and it wore out the tyres through the middle just as if they'd been pumped up too hard. That's an extreme case but you get the idea. I'd say over inflation. If the rear was not tracking right or IRS was out of alignment there'd be scrubbing issues but not centre wear as you discribed it.

It will also have a bit to do with the Wanli tyres as they are about the worst on the market.
But as said the usual cause of uneven wear through the centre of a tyre is caused by over inflation. Try dropping them down to 36-38psi.

Thats true Russ. The tire quality of compound may contribute to premature tire wear on wheels that are under engine load.

Yeah - Its IRS & I don't drive that hard at all...
40psi by far is no way over inflated!!! Most driving courses recommend running running that in your tyres... Cheers |

A tyre wearing in the centre is over-inflated for the driving conditions.

sounds like overinflation... tyre pressure should depend on the tyre and possibly tyre size... not just what someone says..
i had a set of wanli's on an mirage.. and they actually warped and developed several eggs in the tread.... i'd suggest upgrading tyres if at all possible... |

I hear everyone but shouldn't the front tyres also be doing the same.... if not wearing worst than the back!!!
When I bought the car, it came with a brand new set of Yellowsea tyres!!!! Now they are .... The car was bunny hopping as I was driving... They were out of round brand new!!! The Wanli's replaced those crappy tyres under warranty.... & I know still crap but doesn't explain the wear...... |

1, The front is heavier than the rear, so usually slightly more pressure can be used up front. 2, The front is the steering end, so the edges suffer extra wear.

Consider getting new tyres, a 4-wheel wheel alignment and possibly fitting a camber / castor adjustment kit at the same time. These steps have solved the problem on my lowered car with 19s.

Hi All
I've lowered the tyre pressure to 35psi in the meantime all round. I'll see how it goes in the meantime.... Cheers |

Unfortunately the damage is already done, so no matter what you do those rear tyres are going to still wear out the centres first.

Roadstone AKA Nexen are another good tire for the money also.

As some others have said, it's a tyre pressure related issue. Not alignment, not the style of rear end or even tyre size. Try running your next set of reasonable tyres (Not wanlis) round the 34 - 36 PSI mark. I think you'll be more than happy.
BTW. As SOX said, you can run the front slightly higher, due to the extra weight there, but only by a couple of PSI max |
