Michelin Synchrone Problems

Hi all
I recently replaced the Dunlop Gradtrek OE tyres on my 80 series Landcruiser with two Michelin Synchrone (front only) 275/75/16
Since then I have had them back three times trying to get them balanced correctly. They just seem to wobble. They also "tram track" really badly and if you hit a ridge on the road or gusty sidewind they dont just wander the steering wheel is nearly wrenched out of your hands as you change direction.
Before I go back and throw them at the guy who sold them I wondered if there was anyone else who has had a similar experience (either this brand or similar problems with other brands).
Appreciate any help
Cheers
The Pelican

At the risk of you thinking "does he rekkon I'm stupid!", I'll pitch into this one. What about tyre pressures ? The tyre people often put a lot more air into them than some people usually run. Lots of air in the front can give those symptoms...I know :(((

I'll second that... when I replaced the tyres on our falcon(not at my usual place, this was a special offer from a big mob), it had developed a wander, was tracking horribly and got the shakes up at about 90km/h. I took them back and was told they would rebalance and see if that fixed it. After rebalance it actually got worse so I took it to Bridgestone in Kilsyth(I was passing by and the tyres were Bridgestones) though I'd have a chat to their people and hopefully some joy...

Car wheeled into inspection bay, all four wheels removed and examined:

1 tyre was at 60psi(front left), the other 3 had 27psi

3 of the 4(including the 60psi tyre) were counter balanced, they had weights on oposing edges of the rims???

Bridgestone didn't charge for fixing my woes and took a photo copy of the original invoice, presumeably to chase this guy up and sort some stuff out.

Final outcome was 4 tyres balanced properly, 4 tyres @ 32psi and no more wanders or shakes...

I'll third that :).

The Pajero seems to be particularly sensitive to front to back pressures as well. If the front pressures are higher than the back it gets some very strange handling characteristics. It feels like it is tipping into the corner and can be a real handful to control. I found that out the hard way when one mob swapped front to back, pumped the front ones up harder than I usually did the back and didn't bother to check the ones they put on the back. I really wonder what sort of road test they did. Changed the pressures myself once I realised what was wrong and it was fine.

Tim.

My tyres were pumped up waaay too high. The vehicle was dangerous over 80K, wheels tracked the camber etc. Had tyre expert look, balancing and alignment needed. Had specialist place look, they showed me on the u beaut lectronic scope that one side of chassis was longer than the other. Came home and had repair place do a laser alignment...wasn't out of whack at all. I woke up that night and thought "It couldn't be, could it ?" Went and checked tyre pressure at 3 am, and again later to make sure I hadn't just dreamed it. 60psi. Put down to 35 and a different vehicle.
DON'T listen to the "experts" ! Check the obvious first.

I'll treble or quadruple the above....seen them put 55psi in mine
50 in hers!...wankers...their reasoning...rated to 60 (or is that 65)

dunno ....but they're still wankers, and BOB shouldnt let them use his name!!

I have Michelin Synchrone fitted all round to my 80 series Landcruiser and have had no problems, and am very pleased with them.
Run them at 40 with Nitrogen inflation.
Prior to that was not happy with Grandtrek or the Michelin LTXMS which wore rather badly.
A thought have you had a wheel alignment?

Nudenut,
Prior to using the nitrogen, and being a bit slack in the care and maintenance department, my tyres were always under desired pressure when i infrequently checked them.

Bob Janes suggested using nitrogen , and i have done so for the last couple of years.
Tyres do remain at desired pressure for longer and a top up at Bob Janes is part of the deal once they have been filled.
My tryes seem to be wearing much better too.
Cost for the Landcruiser was $7.50 per tyre with refills free.

A neighbour with a holden does swear by it , and says it holds the pressure for about 3 months.

Have used N2 in my work van for wear - not convinced. Put them in my off-road trailer which sits in the garage most times and gets square tyres. Very convinced - also the spare does not "leak" as much...

Don't put them in the Cruiser - go sand driving too often and as such is a waste of money

I have been dissapointed on a few occasions when buting new tyres as they dont handle as well as the old ones. The reason?? tread squirm that u beut new rubber deep treads squirm creating less sure handling than 3 qurter worn ones. However what you describe sounds quite a bit worse. Also try jacking up front wheels and checking for front end play as that could be making things worse than what they are
