Performance vs Quiet Tyres

Better in what sense? For more comfort and quietness, ES100 is better. For dry traction with good wet grip, AVS Sports. BTW, I haven't tried it yet. Comments based on friend's testimony. He was using the AVS Sports 17".

 

You'll have to see where your priority lies when choosing a set of tyres. For myself, I need tons of grip, comfort and quietness is secondary.

IMO, AVS Sports is a shade better than 712 in term of performance but costs more than a shade! The 712, IMO, is the best bang for buck performance tyre currently available. [thumbsup] You can do power slides without feeling guilty! [laugh][laugh][laugh]

No, I didn't say that the 712 lack lateral grip! [sly][laugh][laugh] Whatever good tyre we use, once the cornering limit is breached, it will slide, over or understeer. Some ppl like to power slide out a corner. I'm sure you've seen a lot of these kind of tricks at the WRC...................doesn't they use lousy tyres.

 

What I was trying to say was, with the 712, I can trash the tyre, of course at a safe place like the tracks, without worrying about the costs of tyre change. If you're shod with a $250/ piece tyres, you'd think twice about trashing those tyres, rite?

That is a very difficult question to answer.........too many variables. For me, I'll change by 1.5 years or as soon as there's significant wear, whichever comes first. Rubber hardens with time so should not keep for too long.

 

Look for the threadwear index. My 712 is 280, if I remember correctly. The bigger the longer it lasts.

WRC quite different leh. The cars r set up to drift into corners. [dizzy] Maybe i'm ol'skool but a bit apprehensive when road tyres exhibit these characteristics (esp in the wet!). Been hearing some negative comments on it's wet performance lately. Dunno if there's any truth to that? [confused] BTW, what's the traction rating on the 712?

Mike,

 

How do you find the lateral grip of the kumho 712?

 

I find that the lateral grip might be lacking ..... say compared to my previous ST115.

It stick pretty well in the dry but I lost confidence in the wet. However, it provides pretty good grip against hydroplaning (when in straight line).

 

But have to admit, for this kind of $$, it's really value for money.

It has a softer sidewall, which translate to better ride for lower profile tyres....a plus.

 

Juz wonder how long can it last..... [angel]

I don't think you actually understood my point. I'm just saying with cheap tyres, I won't feel guilty even if I were to trash them. [;)] I certainly didn't mention that slip sliding is a characteristic of the 712. [:p]

 

Even if you're using slicks you can drift if the limit's breached.

 

The wet handling of the 712 is probably not as good as Michelin Pilot Sports or Goodyear Eagle F1. I also believe that the wet traction of top-of-the-range performance tyres might actually be lower than their lower range touring tyres due to thread design.

 

So far I haven't skidded on wet road yet, but then, it could just be I drive more cautiously in the wet. [sweatdrop] The traction rating for the 712 is AA. It may be interesting to note that traction rating does not indicate wet cornering ability.

Lateral grip of the 712 in the dry is good enough for me. Bear in mind that the 712 will start to squeal early but they don't lose traction. Pretty progressive and don't give way suddenly.

 

Didn't corner hard enough on wet road to comment on wet traction but so far so good. Actually I feel it's aquaplaning resistance could be better. [sweatdrop] The threadwear of the 712 is between 280 and 360 depending on the load rating. It lasts quite long compared to similar performance tyres.
