Absolutely cem. Wim have a computer file full of different set up stats for each model ever made. They are very different.

and we must not neglect correct pressure setting..

same deviations apply to other tyres also Chris

and we must not neglect correct pressure setting..

Of course. A million variables a test strives to remove. I'm sure TB will accept the perfect accuracy of any test. But as said nobody is concerned with the accuracy of a test in a golf or Merc, that has a completely different set up to an omega.

For example castor angle on some Mercs is approaching 11degrees, which is enormous and gives very lazy stable steering, where as omega has 5degrees. Much more agile.

While that doesn't change the properties of a tyre, it does change the result of the test bed. That being the car. A tyre is nothing without the car. Be it a shite BMW or otherwise

yes and the test will reflect that. But beyond that, we need the test to be done on an omega which is actually what we are doing here, of sorts.

thats a good one Chris.. Castor angels will change the surface area..
 
but as I said all brands you use will loose surface area of touch so all will be having loss of grip

yep.. but thats not science.. you have to give measurable units..

Good, so you accept different results on another car? That's all we're talking about really.
Further to that, we must then admit that a certain tyre will suit another car(and driver) better. Add in the human element and we then get another preference to meet in our tyre choice that a test can't replicate, again.

Chris you are British.. I cant race on words with you.. but you know that the meaning of different and proportional are different things
 
proportional means test order wont change

yes hence i said "of sorts"

I am sure you may remember, I have suggested several times, that we as a car club have an ideal opportunity to test( I think I actually said review, which on today's evidence won't work either) tyres. Too many resources needed though.

it will on an omega, if compared to, for example, a ford fiesta. Grip level of the specific tyre and it's properties as it sits in the shelf are set, obviously. But without the car it's useless. But any car will use that tyre a different way.

We are talking about matching the best tyre to an omega. For an omega. And only an omega.

Do one test in a fiesta.
Do one test on an omega.

You will get a different order.

nope..

[cem_devecioglu]

unless you add driver opinions which are not measurable..
 
thats a trick where magazines used to change the order as they wish.. 
 
 
I only look measures.. if they dont give, I skip the results..

[feeutfo]

OK guys, can you all not see it? We are a club of Omega Owners, some 10,000 strong. Can you not see an ideal opportunity here to collate 'experiences' (NOT figures) over the life of a tyre?


So rather than constantly disagreeing - we will never agree on the usefulness of tyre tests performed on different chassis - lets agree on what our findings are with various tyres on Omegas

Therein lies the problem. I certainly wont believe Tunnie's recommendations. I love the PS3, which you hate, so you wont believe my recommenations. Chris likes the SC3, but only the MO version, which is 91 rated and under specced for the Omega. CEM agrees with me, but others disagree. I suspect that collating thread will be the longest running debate ever. 

Within the groups of, excuse the non pc terms, but fast, medium slow. You'll receive more relevant recommendations though.

Hence ask a similar minded driver, and know your own mind as a driver, as to what tyres are needed.

Fact is Tunnies tyres are perfect for him. Ask him what tyres are he uses and he'll happily tell you. The error then is, assuming he drives the same way.
Obviously there's no point Tunnie buying sport maxx tt from TB's recommendation either.

Sorry, incorrect.

I have already said my piece on P6000, which I've used on multiple cars. I have also used GY NCT on different cars, and the results are the complete opoosite of the P6000.

The P6000 was crap on the Rover GSi, the NCT was quite good. The P6000 was awesome on the Rover 25 and the NCT bad enough that even Mrs TB moaned about it. And she's a girl!
