TB; I think you are being pedantic here. What you say is true, but applies across the spectrum of life. For example medicines. You can only test them on a small group of people and if it works we assume a class effect. However they are so many variables; genetics, upbringing, allergies, other underlying conditions, other medications being taken etc etc. Surely we cannot test for every single variable. In the same vein of your post, then you would only accept a treatment/medicine if it had been tested on someone exactly the same as you, living in exactly the same place, eating exactly the same food etc; you get my gist? But then there isnt anyone exactly the same as you is there?

I see and agree with your point, but to progress scientifically some compromises have to be made. To completely put down the effort made by a group of specialists seems unreasonable in my eyes.

And like I said before, it seems very unlikely that what you want will ever happen on an Omega.

D it's for exactly the reasons you explain, quite rightly, that tyre tests are useless to us. There comes a point where they are irrelevant. IMO this point was passed years ago.

That's not to say the info on tyres inaccurate or wrong in any way.

It's simply too personal a thing, but only after a certain point. TB likes a car that turns in well without under stear. I like a car that doesn't tram line and holds good corner speed. Show me the tests for these ...?

Only first hand experience is relevant after a point in experience is passed.

Goodyears (f1 asym 2) definitely silent, unless you start slide and sideways   but temperature difference may have effect , not sure..
 
PS3 I found them very good on a friends car (accord).. but tyres were new..
 
for clit I'm using pilot exalto pe2 which was excellent but its a different league..

Simply brilliant tyres. I paid £98 each plus £10 a corner for fitting and balance. My MV6 runs on 235/45/17.

Check out the customer reviews.


.........and avoid Bridgestone Potenza. They are shite.

They are certainly slippery on the Omega. Added to that, they have a MASSIVE rim protector, which will require a camber compromise if used on the front.

[feeutfo]

Yes they where highly recomended by a member here iirc. 010? Noisy harsh and the ones I had, although part worn on a car I bought, had very little grip.

Which just goes to show that one mans grip is another mans sliding around.

These ones had so much rim protection they physically would not fit on the front axle for fouling the shock upright. Although I can't see that being standard tbh.

Personally I also think recommending tyres should be banned . ....unless the owner has owned through out the entire life. It's an easy trap to fall into, as with The Falkens I had.   Tyres can degrade very quickly into something very unpleasant. Comparing through the tyres life at equal stages, as opposed to new tyres compared to the knackered crap that came off.

I have used 215 55 16 size potenzas (adrenaline), and they were a perfect fit.. never seen any problem and any skid despite my efforts..
 
and besides this tyre is used by Aston martin.. and they dont know anything

235/45/17 doesn't fit the front without shock fouling, on stock Omega rims. As to the lateral grip levels, shows how different drivers have different needs .  I have driven these on chrisgixer's car when he first got them, thought they were slippery. I now have these tyres on the back of mine, temporarily, and views haven't changed (although they are very worn now)

and besides this tyre is used by Aston martin.. and they dont know anything

I suspect they have their own variant, not the stock tyre. But even that aside, thats the point, a tyre that works well on a sports coupe can be far from ideal on a large exec saloon with a completely different suspension setup.

back to square one..  we can never agree 
 
if a size dont fit , there are alternatives.. you can use smaller size or spacers..
 
although potenzas have a wide variety,   latest models have 2 different class.. for street use and for race use..
 
adrenaline was the softer one for street use
 
besides cant predict your tyres conddition.. I recommend sanding its surface with 150 grid if its not too old..

and I remember you said they are very grippy although being noisy

...and a very Differant power and brake package that will work the tyre harder and force more heat into it. There by working the tyre ver differently. It may be that the omega can't "activate" them, like Aston undoubtedly will.

I doubt Bridgestone would allow Aston to run tyres with this level of performance cem.

although omega is not that weak car, you may have right there Chris.. Turkey and UK have a different weather temperature range.. mostly over 10-15 celcius difference.. this may effect.. with some effort I still think rears can be heated but for fronts you need to use longer braking..  but at that point the question arises why Aston choose it , with that cold weather as they also use street type which requires less heating..

[TheBoy]

back to square one..  we can never agree 

I think thats the key thing here, we have wildly differing views on the usefulness of tyre reviews that have not been done on similar cars, with similar suspension setups, and similar style drivers.

I have personal experience of how the same model tyre can vary so amazingly differently on different chassis designs.

[TheBoy]

with some effort I still think rears can be heated but for fronts you need to use longer braking..

Sorry to pick up on just one small part of your post, but just wanted to highlight that my driving style puts lots of heat in the fronts, and not much in the rear.  Even in Miss Daisy mode - I took Webby The Bear's car for a spin the other day, driving slow as we wre testing MPG readings, and when I got back, the front tyres were warm, rears quite cool.

[cem_devecioglu]

ok then,  I have a question..  do you believe that ling longs or any avg tire will perform better than potenzas on the omega ?

[cem_devecioglu]

and Chris why do you go for Contis generally which is also a test winner
