330 (ci) tuning?

I've just had a full set of PS2's put on the M3, and their great, only been for one drive but way way better than the rather bare Contisports I had on there.

PS2's rock, their not advertised as cold or wet weather tires though, so just drive more carefully in the wet.

Which is my point - I know they are good in the dry but we live in the UK. I doubt the roads will be dry at all until next April at the earliest. Why write off half the year of fun driving by fitting tyres that rock in the dry but suck in the wet :p

Garrett doesnt appear to rate their wet performance on his M3?

Unless I missed it he doesnt mention there wet weather grip being bad just the fact there not advertised as wet weather tires so take more care.

A few guys on MLR have tried these now and remark on there wet and dry grip being very good with stiffer sidewalls over the F1's :)
 
Well blokes on forums proove nothing, all the guys on the BMW5 forums think F1's are the most amazing tyres ever, it only takes one person to jump on a bandwagon and everyone else to follow, just like on the Saxo forums I'm sure Kumho's are awesome :p

Thats why I stick to fact over opinion when it comes to tyres. If I can't see proper figures for the performance of a tyre, I won't trust it until I do. Peoples perceptions differ wildly - for example, clearly with F1's, I find them absolutely amazing whereas Merlin finds them poor - two different people, two totally different takes on the same product.

This is why opinions are a bit dubious with tyres..

Unlike anything else, you can't give them a quick try to make your own mind up, and most people will try one brand every 2 years or so..
 
You have to take information from different angles and make a considered choice.

It's true though that a set of tyres can perform better on car A than on car B. Different cars different suspensions, different results.

Personally I dont like the sidewalls on the GS-D3's and I dont like the way the outer edges disolve in dry warm conditions. They soften up way too quickly when you introduce some real heat to them. The grip once down to 30% tread left is also rubbish - they "go off" too early.

The PS2's exbibit even wear and still deliver grip right down to the wear indicators. They are more expensive, but you get that money back with even wear and continuous grip right down to the bone. Bridgestones are the same - they wear flat, although some Potenza's do go off at 70% worn.

For the record I don't take much notice of magazine reviews when it comes to tyres unless of course they've been done with the exact same car I have, in which case it's a bit more interesting but still to be taken with a pinch of salt, imo. I'm not into referring to a magazine for advice on what to eat for dinner tonight.
 
The difference being if tonights dinner is crap you can have something else tommorrow. Or you can directly compare two dinners yourself easily. You can even do that when buying a car.

But you are stuck with your tyre choice for at least the next 10k miles and cannot easily compare to other brands.

And yes, different tyres work differnetly on different cars but if the size is pretty much the same I still think a tyre test is far more useful than the opinions of people on forums.
 
If the tyre test involves a different car with 200 more or less kilos than the car you own, a different suspension set up and maybe even different driven wheels - I'd rather listen to people on te internet spouting off about the exact tyres you're considering on the exact car you own.

A) Right tyre on the wrong car with a professionally produced result, or -

B) Right tyre on the right car with the majority of the general public saying the same thing.

I choose B.
 
But you know how fickle the general public is. Look at the repuation the 306 DTurbo has amongst the general public on here...

General tyre characteristics are going to be similar even with different cars. If a tyre is good in the wet on a VX Monaro it isn't going to be teflon on a 330Ci?

I understand both your points of view if thats possible. Maybe its down to driver experience as well though. With all due respect mr fox, from reading posts here merlin has had his fair share of RWD cars whereas this is your first. he could probably make a ford escort on DitchFinders go round a track quicker than you with GSD3s on the 5. Thats no reflection on your abililty, its just that what some people may deem to be a good tyre from numerous 'reviews' may not be classed good by someone else who say has more experience at pace driving, flinging it around corners, etc.

How many reviews of tyres are conducted over the cars whole tyre life? For example, these magazines that live with a car for year, do they mention the tyres? do they even have GSD3s on for that long?

Peronsally though, i'm like you, i've always liked GSD3s and would always buy them over any other tyre.
 
This is actually my first RWD car, not that it makes any difference - took me about a day to get the hang of it, just turn the electronic crap off and find the limits and remember them.

One question - how many high performance cars come with GS-D3's fitted as standard?

What does this proove other than which tyre manufacturers have which deals? My car came with utterly gash factory fit tyres, proves nothing :p
