I took advice from others on here and ended up putting these on mine..
Kumho KU31 XT tyres (XT = Harder sidewalls)
I must admit it totally stopped the tram-lining and the grip in both wet and dry is excellent.. Also during the snow period the performed well and never got me stuck and the snow hardly got stuck in the treads.

I seriously considered those, but couldn't make the necessary compromise on the grip level, so had to pay a bit more for something else  :'(

I've run Toyo's on the MR2 quite a bit - they have very soft sidewalls, which means I can't see them suiting the Omega somehow.. but I'm happy to be proven wrong :)

Hi so which soft or hard wall tyres are more prone to tramlining
I had conties which i had tramlining swopped them for goodyear F1 no problems for the past 5,000 miles

New tyres will always behave better than old tyres when it comes to tram lining. Maybe this catches people out? Needing new tyres due to tread depth and noticing the car handles poorly, then fit new tyres and suddenly the car handles better, therefor the new tyres MUST be better than the old ones, right?

Wrong! Been there and got that T shirt, made the same mistake. Experience finally taught me to take the worth of a tyre over it's entire life, how it behaves when new is very very different to how behaves worn out.

Typically, on the omega, tram lining will start to creep in from about 50% wear IME. Question is how badly they degrade.

agree the previos model was better, but fit any Falken to an omega at your peril!

Said this before and I'll keep saying it as long as I live " NEVER NEVER EVER FIT FALKEN TYRES TO AN OMEGA......[size=24]EVER[/size]


My, my, I've got some saving to do!

Perhaps that's why I move sideways unexplainedly! :o

I will have to go for the part worns after all to say goodbye to the Falkens sooner rather than later. Still, will prompt the wheel refurb at the same time.

Bugger! >:(

Potenzas and Contis it is then!

that is my experience yes  :'(.  Worth checking bushes etc, but ime changing from Falkens improved the handling way over and above any failed bush.

Wish I new exactly what it is about these tyres that affects them so.... I guess the side Walls are over soft.....?

Speeking to Wim re BMW's run flats they talk of replacing them with normal tyres. Firstly to stop the wheels cracking :o and secondly to stop the tram lining. The theory being the side walls are so stiff they transmit every road imperfection through the steering.

So soft side walls are better if the opposite is true!?!?!?  :-/ with that in mind I can only assume the Falkens go too far the other way and are too soft to give stability, hence the water balloon comparison earlier.

So is it safe to say the omega needs it's tyres in a certain range of sidewall stiffness to work? Falken sidewalls are exceptionally soft, and maybe thats what makes them so quiet with comfortable ride?

On the other hand Dunlops seem to give the most planted and sure footed directional feel I've ever encountered on an omega, ride is fine, but I think it's safe to say they are not known as quiet tyres.
So are we entering the world of the tyre maker? a world of continual compromise and the elusive best of both(all)worlds brake through, the perfect tyre, maximum grip v minimum wear. Quiet with compliant ride v straight line stability. Good wet grip v good dry grip....and then make it work on all cars front or rear wheel drive or 4 wheel drive, big and heavy, light or small.

Bound to be a tyre that's a mare on the Omega, and one that works well. And I guess that must go for any vehicle.

The tyre tests don't really help past a certain point, unless the tyre is tested on at least a similarly sized same wheel drive car as our own, as the Falken proves, we're not necessarily going to get the same result as seen in the tests.  :'(

Ps, I'll stop short of mentioning that we have a perfect opportunity to gather tyre info on our own specific vehicle on a dedicated car forum. Gathering such info in a presentable manor is and would be a nightmare to implement.

However as said before, such info would help others to make an informed choice, and not make the very expensive mistake I did.  :'(

Ok that's enough from me on this thread, hogging it a bit  :-X.     ;D

Chris , I'm afraid I cant agree with that..I have never seen a tire finding place in top three drops to bottom..

yes.. tires change behavior with thread wear and time and temperature, but I dont believe the best tire for a fwd car is the worst for rwd.. over the years I have visited many tire test sites and concluded that good brands and models dont change place too much .. have you seen a continental or a potenza or an eagle f1 in the bottom..

these tires are used for cars which are extremely expensive and I dont think the factories just go and buy a set..

Falken and p zero being an exception then? Well certainly the Falken. And TB's experience with pirelli p6000 and the Rover?

Or look at it another way, if the Falken behaves the same way on other cars as it does the omega then how do they sell any at all?

Uit I do take your point, although there are some add balls as we have just discussed.


Do you have any info or tests on the Falken cem?     Ok ok, obsessing a bit now.  ;D

Ps, post in question edited slightly.  ;)

Falken 452.. have many consumer and review complaints..and some reviews also says it tramlines badly .. ..and I dont remember it wins any test..anyway its a budget tire.. thats the reason why people buy .. for example michelin energy saver .. thats an awful tire but people here buy it :(


and for Pirelli pzero (not sure which submodel  you mention) but as general acceptance these are summer performance tires, needs to be heated before they start to grip and wont work on low temperatures..

pagani used those tires on a 678 bhp 780 Nm car costing 1.8 million £ ..

Bear in mind my experience is primarily on the MR2 (I did have some Toyo's on the 300ZX as well, but not long enough to really get a feel for them before I grenaded the gearbox) but the softer sidewalls are better for tramlining than the super-hard sidewalled stock RE040s..

Then again the RE040s are awful in general, so it's a bit of an unfair comparison.

What you gain in the lack of tramlining, however, you lose in turn-in 'feel' as the Toyos are definitely considerably more 'wooly' at the front end.  Once you're turned in and really leaning on them then they feel great as long as the slip angle remains constant, but once you start needing to make course corrections they're not as good as a harder walled tyre.

All depends what you're after really .. I quite like the Toyos all things told purely because they are incredibly communicative about the available grip level and very progressive on the limit - though the absolute limit of grip is undoubtedly lower than a more expensive tyre.

Funnily enough, those are exactly my feelings about the KU31 having driven on them for a while. Once you've told yourself it's going to grip and turned in with a bit of confidence, they are quite communicative, but they feel very understeery and light as you start to turn in in comparison to some tyres I've tried, and you really have to trust them in the wet, although, as you say, once you're in the turn they have more feel than I'm used to in the Omega.

Fronts are getting reasonably well worn now and while there's a little bit of wandering it hasn't prompted me to swap them to the rear yet, which is a good sign, especially as I think I've got a knackered wishbone bush. >:(

A couple of years back i had a lexus ls400 luxobarge and it was fitted with a set of falkens, i have never had a car more frightning to drive in the wet than that thing. I had a full geometery check by tony at wim and asked him for a recomendation for tyres, he advised a set of toyo proxes. i bought a set and the car was transformed into the safe car they are known to be, they were superb. the falkens were changed with about 6mm of tread on them and will never use them on any of my cars.
Having said that the omega is due some new rubber very soon and have already had 2 new michelin pilot primacys fitted and the car is now soooo quite on the road and tramline issues have gone from the pirellis p7000,s i have had for the last 4 years.
In the end you pays your money and takes your choice, so to say, so try to make the right choice before it hurts your bank account. :'(
