Oh, and I never answered Kevs post earlier.
On a scale of 1-10, 

10 being worsened with Falkens.
( You remember driving with two of those fitted. And i'm sure TB remembers driving with all 4 fitted )
.
.8 TB's totals cabbaged clown car michelins,here
.
.
.
4 the current sc3 o1 Audi variant is about here
3 or maybe here
.
1 best for not tramling being mo sc3

So not a massive issue. But it's bloody annoying having coffee up for them.

The SC5s are coming in around a 9....

bloody hell, worse than the clown tyres? Do you think the other issues are included in that 9 or is that purely tyres?

[TheBoy]

Who knows.

The car went from Heinz 57 (no real issues, bar lack of grip), to those I borrowed from you (no real issues, except rears keen to light up), had a load of suspension work done, stayed on yours for about 2 weeks, then onto SC5s.

All the fun started with the SC5s. I assumed it was the release agent, as they initially squealed at corners or brakes.


So far, I have nothing good to say about them. But as you know, other factors are at play here.

Yep, I'm liking the 1 rayon sidewall, same as mo. ...for what it's worth...?

I don't think you can use it for any judgement.

Case closed then? Yes?

Yep. Runway Enduros and you can afford to bin them at 4mm.

[05omegav6]

A ringing endorsement from Kevin then

They grip well down to 2mm, but get quite feathery the closer you get to the limit

[feeutfo]

There you go then J. Runway Enduros. Fixed.

you know my approach to tyre makes........

Btw I double checked, it wasn't 245 45 profile at all. It was 245 40, hence it fitted.

According to irmschers tuv cirtificate for sport stars, 245 40 18 93w is the correct listed  size, this is the same as the NON tramlining mo, and one of two options.

The other being 235 40 zr18 which is the same as the Audi ones I have fitted now. The only difference is the these are extra load. But I don't know what load that equates to. Does extra load mean it would have a load figure of more than 93?


...and what is/how do you work out, the load rating of a tyre for a car? I'm thinking anything over 93 is too much for omega, potentially. Cirtainly the tuv cirts don't recomend anything higher with these wheels.

It's a fairly detailed document.

[TheBoy]

TIS says 94W for a 2003 3.2 on 235/45/17 on a 3.2 (actually, the same for all V6).

My understanding of these ratings (load and speed) is that they can be exceeded, but never reduced. Doing so may not only impact the validity of the insurance, but could end up leading to catasphoric failure, which will end in tears at bedtime.

Load rating values (ie, max weight applied to that tyre) is described:
http://www.tesco-tyres.com/help/load-rating


Now GM do not list any 18" sizes, but I don't see how the load index would reduce with a larger size, as each wheel still needs to carry the same weight.

load ratings of tyres are, you'll not be surprised to find out, measured from a completed tyre during a test.

[feeutfo]

I was going to let this go, but having driven the car since, much as i love it, the front tyres are really ruining it for me tbh. Its not massive tram lining, but...

So load rating then...

Here's the chassis label on my b pillar.

[feeutfo]

According to page 213 of the owners manual the first line under the chassis number means;

Permisable gross vehicle weight of      2200kg
      "         gross vehicle train weight  4075kg for pikeys only
      "          max front axle load.         1080kg
      "          max rear axle load.          1155kg


The car ia a saloon, guess estates will be different.
