CU2 Major Tyre Issue

**p0c1** · 13-03-2012 08:05 PM

I got the same Humm / Whooring noise coming from the front left tyre as well..

anyone got solutions?

Checked on the dealer, and they mentioned it something to do with the tyres...

I'm just a bit paranoia if it's something to do the wheel barrings... (still under warranty)

any suggestions?

The Michelin Primacy HP in 235 45 18 tyres that come oem with CU2 luxury is asymmetrical. you can rotate front right to left rear and front left to right rear. or front to back. which ever tickles your fancy

but X rotation is probably better.

the rear suspension design on the Euro does run on some camber, but nothing extreme like -2 degrees plus.

best way to prevent any problem is to rotate them regularly and get wheel alignment check from a trusted place (Sydney has 2: Heasmans and Spinning Wheel Tyres).

i myself am still searching for Brisbane's equivalent of wheel aligner though as i will need a check soon.

Just 2? I beg to differ...lol

Alignment will help with this issue, however there isn't much factory toe adjustment so if the camber is getting much past 1.5 degrees neg then you should look at getting a camber and toe adjustment kit.

How much camer does the stock cl9 and cu2's run? It as hell looks like a lot.

Depending on the age of the car i've seen them range from 1.25 through to 2.5 neg

Mazda 3 and Ford Focus have the same issue.

The suspension is tuned for understeer, but its also designed not to turn into lift off or snap oversteer, this is where the rear camber comes in - static negative camber means that when the load becomes lateral the rear wheel stands up and ensures that full tyre contact is as close as possible.

Downside is camber wear - drive your car harder and enjoy more even tyre wear!

Hey guys check the below link which takes you to a Thread from Blue Euro in November 2010 which covers the Rear Negative Camber Tyre issue I might be having. I'm interested in everyones thoughts ? http://www.ozhonda.com/forum/showthr...ferrerid=32724

That thread shows you the need for regular wheel alignments.

You should really check the alignment as soon as the car is picked up from the dealer. We see alot of pre-delivery vehicles in the workshop and many have incorrect toe settings with alot of them toeing out severely.

Senna, can you recommend any good aligners in S.E. Melbourne ?

You could try Bridgestone Rowville - thats east melbourne i think isn't it?

I've spoken to Stewart there a couple of times and he seems like a good guy that doesn't talk crap! Can't say i've ever been there though!

Thanks Senna, Rowville is the bordering suburb to Dandenong, it is a little east but not too far from me, about 20 ks. I might give Stewart a call and see what he thinks. The noise coming from the front tyres is driving me nuts and I'm not enjoying my drive at the moment. Cheers.

No probs - perhaps when you change tyres you can try something with a harder compound, it may not feather the tread blocks as easily, but handling will not be as good as soft compound...
