Tramlining SEC !!!!!!

[Ducati]

Hi can anyone recommend a particular tyre for my 18" AMG style split rims. They are currently 245-40 & the tramlining is just unbelievable.

I have had a four wheel alignment & new steering damper & everything checked but the tyres are just terrible to the point of nearly dangerous at times.

Just wondered if anyone has found a particular tyre that does not tramline too bad?

I love the look of the rims but am now thinking will I be able to keep them on due to the tramlining getting on my nerves

Help Please !!!

Go back to at least 16"rims would be my advice sorry. That's the only sure solution. The suspension on these cars was designed with 70/65/60 aspect ratio tyres in mind.

I know that most people are going to say that

But surely there must be a tyre that works quite well

I was running 235/45/17's on my 560 SEC and that had a tendency to tramline slightly....

The wheel was a 17x8.5 ET13.

18" really don't suit the SEC. They are also known for tramlining on the OZ splitrims when used with the 10" rear.

It's a case of look over handling I'm afraid.

yeah I used to get a lot of tramlining when i had those wheels on mine, although it has a lot to do wit the roads as well. Could try going to a stretched tyre giving it a smaller contact patch, I have 9" wheels all round but run stretched 205/55 tyres so there isnt much tramlining

Tram-lining can be cured.

There is two main reason for this condition
1: Tyre sidewall compliance: The stiffness of the wall due to "the build" or the suggested pressure invites a "communication" between the actual contact patch deviation and the rim, in this event manipulation of the pressure "within reason" can reduce the complaint.

2: Toe tendency: The Mercedes requires a slight amount of static toe in because the front wheels are being pushed, from here the dynamic desire is zero toe. Since the car lives a long life in the realm of worn it can be assumed there will not be a perfect dynamic zero.

Toe "when wrong" applies force to the tyre laterally generating a involuntary steering action which you the driver has to counter ( tram-lining ) In order to belay this phenomenon the geometry calibrator needs to find the "toe tendency", this is the migration of the Toe during the suspensions "bump and droop".... Since this migration is dependant on the level of wear every car is different but a simple calculation would establish the perfect Toe.
