Lowering a GTD

[Wurzel]

I thought Falken was an independant Japanese manufacturer?

It's a bit complicated but Falken are a subsidiary of Sumitomo Rubber Industries, who own the Dunlop brand, and Sumitomo formed a joint venture in 1997 with Goodyear and they agreed to manufacture tires for each other's markets, including Dunlop branded tires. As part of the agreement, Goodyear acquired 75% interests in Dunlop Tyres, the UK company which Sumitomo had formed, and in Dunlop Tire Corporation. Goodyear and Sumitomo also made investments in each other.

Really? Michelin tend to be noisy tyres, lower profile tyres tend to be noisier than higher profile ones. Read this tyre test the Hankooks are the quietest by far:

What a load of bollox!    Michelin are very well known to be the quietest tyres available!  Looks like you have been reading too much ChavPower MaxPower magazine!

The cost of a tyre does not tend to tell you anything about how noisy they'll be. And my point was fitting 19s and lowering is going to have negative impacts on comfort and day to day useability.

What a load of bollox - part deux!  Cheap tyres are cheap because their manufacturers spend considerably less money on R&D.  Michelin and the likes spend millions - which is why their tyres are used on some of the fastest, heaviest, and demanding cars, trucks and busses in the world.  I don't see many Hankooks being fitted to Bugatti Veyrons, or Porsche 911, or RenaultSport Megane Cup cars! 

yeah the test i refered to was a load of bollox 

Erm - yes, it was - utter bollox, for a shed-load of reasons:

• the load index for each tyre was NOT stated - were they the standard load, or were they extra load, or what?
• Porsche require a specialist 'N' tyre rating - yet only TWO makes they tested had this - the others did NOT!
• The test included a massive change in tyre bias from the standard Porsche sizes - the rears up from 265 to 295, yet the front widths remained unchanged!
• those 295 width tyres have massively deformed sidewalls, becauase they were mounted on rims designed for 265!  Look at the pictures in the article.  That is seriously dangerous.    It places the shoulders of the tyre under massive stresses, an WILL cause the tyre to catastrophically blow out if used at three figure speeds on autobahns
• Porsche spend thousands of hours and miles testing to get the optimum tyre sizes - but some journos think they no better!
• Porsche spend thousands of hours and miles testing to get the 'best' tyre type and brand - and if Porsche found that Korean shyte Hanfook tyres made a Porsche perform better than with the Mich or Contis which they normally use - then Porsche would factory fit them - but they don't!  Wonder why? 
• due to the massive tyre shoulder deformation, ALL of their tests which involve ANY cornering should be voided, for two reasons - firstly, the Porsche was NOT designed to use those sizes (and will not have been 'set-up' to use them), and secondly, the tyre manufactures did NOT design their tyres to work with such a sidewall deformaton

And you think that test is a 'reliable source'?   

Honestly, if you think I meant all cheap tyres are good then you're not a very good reader.

Erm, how well a tyre may perform in a certain restricted aspect of a test does NOT determine the overal 'rating' of a tyre.  Even if it were to come tops in all the tested categories, there are still many other variables - the obvious being different cars.  As another posted pointed out, a tweaked version of a front wheel drive family hatchback (ie a Golf GTI) will respond very differently to a rear engined rear wheel drive purpose-built sports car!

Then you need to consider 'customer service' - both Continental and Michelin have absolutely superb customer service, whereas most of the Japanese and asian, along with Goodyear/Dunlop have shockingly poor customer service!  Yet customer service is NEVER reported in these tyre tests

Some are good. Those Honkooks are good and out-perform Michelin etc. You seem to be one of those people with no concept of it being possible for a non-premium brand producing anything decent.

That test was SERIOUSLY FLAWED - so Hanfook didn't 'out-perform' anyone!

And I am NOT 'blinkered' to some kind of 'premium' brand loyalty.  If someone asked me which luxury mid sized limo-type car was the most reliable - I would positively steer them away from a Merc E class, and point them to a Lexus GS.  And if the same 'reliability' question was asked for a small family car, then I would ONLY recommend a Toyota Corolla.

But with tyres, then ONLY THE ABSOLUTE BEST should do - they are the ONLY thing which is in contact with the tarmac.  You could have the most powerful engine, the best suspension, the most powerful brakes, and the most gifted driver - but the weakest link will ALLWAYS be the tyres.  That is why I personally will NEVER compromise on tyres.

That's fine, just dont talk to me.

Erm, it's an open forum, and I'll respond to anyone who I think fit, not you!

Interestingly that Autobild report says the Hankooks were quietest measured from outside, but sounded 'overwhelming' inside... maybe a translation error. I've traditionally run Bridgestones but have to be honest I had no idea whether they were noisier than other brands until reading that.

Hmm, hadnt noticed that actually. Looks like the measurements they took were for outside. I dont see the point in that tbh who cares how loud it is for pedestrians!

The actual 'measurements' were taken from the outside - the big microphone in the picture gives that away!

But the comment about it sounding 'overwhelming' on the inside, from what I can gather, are just the opinion of the test driver whilst in the car.  So maybe the Hanfooks are creating some kind of resonance which is being transmitted through the drivetrain?

Well that's pure speculation and shows how poor that part of the test was, concentrating on outside noise is just ridiculous. What driver is going to give two sh*ts about that?

oh Mr T_T


new dleivery for ya, you have been using them up at a fair rate in this thread

[R32UK]

^^ LOL

for what its worth when i put my 19" wheels on my R they did effect the handling, fuel consumption, and ride. Handling was worse. fuel consumtion was worse. Ride quality was better

[Wurzel]

If the car has gives good feedback you should notice these things.

As for the Auto Bild test, I guess if what T_T has pointed out is true then it's a pretty shoddy test and I'm disappointed.

It is quite stupid to use a Porsche actually since T_T is right they do have their own tyre standards. What's more baffling though is using rear tyres that are wider than normal.

Yes, lower it.

Huh, wft ARE you on about, Chuff?  I certainly ain't being BSing in this thread! 

Anyway, your constructive contribution is . . . . .?

Sadly, 'drive by' exterior noise tests are quite high on the EUs priorities!
