Power Race has it printed on the sidewall. You can check out Michelin's website for me info on the compound distribution for the various Power Race models.

 

Pirelli's range from soft to hard, SC0 being softest, SC3 being hardest. (Do we even get SC0 in sg, or is that just for their Pirelli Corsa Superbike tires?)

Would like to ask...Normally tires have like 120/70...Would like to noe wad does tat 70 means?

[Hartholomew]

Would like to ask...Normally tires have like 120/70...Would like to noe wad does tat 70 means?

 

For example,

 

If you look at the sidewall of a tyre, you would probably see something like this:

 

120/70 ZR17

 

The first number (120) refers to the width of the tyre in mm.

 

The second number (70) is the aspect ratio (height), which is expressed as a percentage of the width of the tyre.

 

eg: For a 120/70 tyre, the aspect ratio will be 120 multiplied by 70%, which is 84mm.

 

The first alphabet (Z), refers to the tyres speed rating. Z is the best you can get for road legal DOT race tyres.

 

The second alphabet ®, refers to the construction, which in this case, R = Radial.

 

The last number (17) refers to the diameter of the tyre, meaning that it is meant for a 17 inch rim.

 

Other than that, you can find the compound type reflected also and even the when the tyre was made.

 

Look for 4 numbers on the tyre that seem to stand for nothing. eg:1106.

 

These numbers mean that the tyre was made in the 11th week of 2006.

 

Just some additional info, as I have heard some concerns from the grapevine concerning tyre age.

 

Shelf life of a tyre if stored in a cool place out of direct sunlight can easily be 2 years or more. 5 years maximum i think.

 

Simple yeah? Hope this helps.

5 years is way too long bro....2 years is acceptable....

 

cos when they manufacture the tyre ie; 2505

 

normally shipping will come in '06......

 

correct me if im wrong...

Hey Hart,

 

I'm about to change my tyres but can't decide what to use.

What i'm asking is should i go for those that's for road/track use example M3/2CT?

You think that's good enough?

 

I've never use race tyres before example Michelin Power Race/Metzeler Racetec K2.

You think that will improve my riding on track? As you know i'm riding at snail pace on track so maybe these race tyres will make me more confident?

 

Appreciate your advise.

Hey JK!

 

How you been bro? Wasted I did not get to talk to you much at Lagudang Seca yesterday...

 

Anyway,

 

There are many ways to approach this subject. I cannot say for sure which is the right angle of approach for any particular individual, but I will give you my scoop on things since you asked.

 

As always, I hope I do not step on any toes here and apologize in advance if I make any mistakes.

 

Here goes,

 

My coffee bean buddy (Hint: The most beautiful K5 in Singapore and JB!) and I were discussing this same topic the other day, while ogling at the fine examples of the female form as they strolled past.

 

The topic came up after Colin Edwards tested the Michelin Power 2CT on a YZR M1 (Actually it was my bike on loan to Colin - Hee Hee) at Sepang, with extremely impressive results. People were shocked that a street tyre could lap the circuit that quickly.

 

This raised the question of whether we locals really need DOT race tyres.

 

On one hand, it may be true. Why am I wasting money using the stickiest rubber I could find, when someone else can lap so much faster with lesser tyres?

 

After a long discussion (and many more fine females), we came to an agreement.

 

Although it was a great testament to the capability of the tyres, the lap time set by Colin Edwards cannot be compared to our own lap times.

 

The reason being that Colin, would probably beat us all even if he was on a Super Four, was on the best motorcycle that money can buy, with so much more horsepower and mechanical grip, courtesy of the best Ohlins can offer; that it was like comparing Apples to Oranges.

 

I think of it this way: Every single rider is different and has different needs. There are many different factors such as running gear (suspension, engine, rider skill), but lets just focus on rider skill.

 

For this example, lets term grip from the tyre as money:

 

THIS IS ALL FICTIONAL!!!! DO NOT GET PISSED OFF OR ELSE I WILL TOO!!!

 

5thRider can ride at 1.40 at PG comfortably with $1.00 of grip.

 

Obviously, on the same tyres with $1.00 worth of grip, I will crash long before I get close to that kind of lap time even though I have the same grip as 5thRider.

 

I probably need more, maybe $1.50 worth of grip, just to replicate 5thRider's times.

 

Simply put, I just do not have the necessary skill even though I have the grip.

 

WHERE AM I GOING WITH THIS?? READ ON...

 

Just to share, I made up my mind that I will NEVER compromise grip ever again about 4 years ago.

 

I crashed my brand new 636 at Sepang's Turn 4 after the stock Michelin Pilot Sports overheated after 5 laps, becoming goo-ey.

 

An old friend of mine told me to get a set of Supercorsa's for the track but I refused, saying that these tyres are more than capable for a newbie like me. Besides, I could see many other (albeit, much more experienced) guys flying on the same tyre. (There was a Ducati 999 that was one of the fastest on that day - on the same tyres!)

 

After I crashed, I asked myself how I could have crashed. That Ducati guy was going ten times faster than me what!?

 

It is then that I realised the difference in skill. All because we had the same tyres does not mean that I could match his pace.

 

Again using money:

 

Ducati guy can lap at 2.30 with $1.00 worth of grip.

 

I can only lap (and later crash) at 2.45 with $1.00 worth of grip.

 

I then realised that the extra grip a pair of stickier tyres had could have saved me that painful crash.

 

SO,

 

Why skimp on grip? After that incident, I never compromised on grip. I always fitted the stickiest tyres I could.

 

It was a idiotic, miserly mistake that cost me $800 in repairs because I wanted to save $400 bucks.

 

Conclusion:

 

I think that you should fit the best tyres for the purpose. You want to push yourself on the track? Find your limits? Explore how far you can go?

 

You better fit the stickiest pair of tyres you can afford.

 

As long as it does not:

 

- "break the bank"

- Square off easily as you commute with them so much.

- Be a waste of money as if you rarely go to the track.

 

Even if not, just imagine what a better tyre can save you from on the track.

 

If at all, I think that it would make more sense for 5thRider to use a road tyre and a Newbie use the DOT race tyre.

 

Why?

 

Beacuse 5thRider has the necessary skill to control and manage what grip he has.

 

The Newbie does not have the necessary skill and needs all the help he can get.

 

As for your question about whether it will make you more confident, I say YES.

 

The lack of grooves near the edge of the tyres help give a more confident feel. Road tyres like Michelin's POWER or Metzelers M3 "wiggle" a little when cornering hard becuase of the grooves pushing in on the open space.

 

As long as you abide by the basic rules like warm up... etc...I believe that it will make you SAFER & FASTER.

 

GO FOR IT.

Great write out,excellent for a newbie to analyze wat ur enphasizing..GREAT WORK!

 

[ambasnakeman]

just to share.....no venom on u meow

 

its only when i was using the one of the worst street tyres on r6, i learnt about throttle control.....had no clue what is throttle control when i was riding 400......

OH My God... i just ask 2 questions & i got a book about it!

 

On a serious note, i really would like to thank you (from the bottom of my heart, not my ass ok?

 

kekeke) for taking time & trouble to advise me on the tyre subject, even thou i've only known

 

you only recently, in fact, i've only know everybody only recently too!!! I think from a newbie's

 

point of view, it's really great to see guys like you that bother to explain to us!!!

 

2 thumbs up to you dude! Again, a very impressive & comical write-up!

 

I'll know what weapon (tyres) to use on my next track day! I'm quite sure that these gummies

 

will definately help me with my confidence. I'm still trying to break the 2 minutes barrier (guys,

 

please don't laugh ok? ) Just only recently, i took Charns riding clinic to learn the basics.

 

I can read his mind saying 'JK, please don't give up your day job! You an embarassment to me &

 

the whole sportsbike community! You're my worst student i'd had for years!' kekeke

 

I seriously feel that i've got room for improvements.

 

Anyway, thanks again for the advise.

[Hartholomew]

Hey Fr

[Hartholomew]

You are

[Hartholomew]

You are always welcome Fruitcake!

 

Dont worry, no one is laughing because we were all Newbies once upon a time and know how it feels.

 

Ride Safe mate (But as fast as you can)

 

Thans Thans Rein!

 

Hey Snakeman,

 

No offence taken mate. None meant here too dude:

 

I totally agree with you on the "learning throttle control" bit.

 

There are many ways to view this topic Fruitcake has brought up. This is just from the "safety and no-crashing angle".

 

I posted what I did because I think Fruitcake might be better off getting a handle on his machine and learning it's capabilities and characteristics first.

 

I for one might suffer "brain overloading" if I had to learn everything about my bike, riding basics and throttle control simultaneously, while having limited grip all at once.

 

 

Cheers,

HOLY COW! TAKE COVER!!!

[NoLogicOne]

Hart,

 

What you said is true.....I have frens running to me saying how good certain street tyres are, "proven" in track, etc etc.....I always asked them who is the rider who tested it and told them to find out more about the history and capabilities of the rider. He could do it does not mean we could, but the test on the track would give us confidence when using the same tyre on the streets.

 

But some still insisted that if the "test rider" could do it, so could they....er, well, it's not nice to dampen other's racing spirits, so it's up to them to try.

 

I've seen some knee dragging shots of bikes on Sports Touring tyre advertisements, but does one try to knee drag Metzeller RoadTech Z6 or BT021 in PG?

 

Cheers!!!

 

Hilary.

[ambasnakeman]

HEY,

 

got 1 ang moh mag.....got advertisement for IRC sport touring tyre.....rider can elbow drag....

[Hartholomew]

HEY,

 

got 1 ang moh mag.....got advertisement for IRC sport touring tyre.....rider can elbow drag....

 

Eh, I also use to use IRC tyres ok... very good ah! Made out of pure granite. The road will wear out before the tyres!

 

And if people start using IRC tyres on the track, you know who to blame - (The reptile)

[hirman88]

dunno much abt bikes bigger than 250 anyway when i was on AP cup 2005 i still used my old pilot race a yr old from 2004 ....1st rd @ sepang took out d rear rims n people ask wah bang tukar tayar (change tayar) .... i say no reverse rotate coz d left much more n right finishin ...hehehhe ..... got 2 d pirelli man paid himRM5 he ask where the new tyre i say no just reverse rotate can ...... he was shock can me ...my pit crew den answer this tyre mcm audio cassette la got side A n B ..... d pirelli man get shock ..... anyway luck was there n got 3rr on dat rd ....

 

I dunno much abt tyres but i learn frm some malaysia riders ...especially d cub riders if they my nsr tyres they say still can la still handsome still can go ....... anyway 250 not much HP la maybe mine only 55hp

 

Just an info during my asia rd on gpr70 d 250 clocking 1.38 on PG ..... me dat time clocking 1.53 n fatsest for me on gpr 70 is just 1.48 just imagine how fast r they on d same model tyre ...skills r important

 

complain less ride well ...hantam saja
