Best Dot Race Tires.....

[Corse]

Has anyone tried BT016 Hypersport?

What r e fed back?

i intend to get it for track use, do u guys think issit suitable??

went to check at Youtube for BT016, those racer used it like a slick tire, can corner til low.

i jz wanna know issit a soft n sticky compound tire.

Thanks

 

 

If i'm not wrong, the front tyre has medium in the centre, soft at te sides.

Whereas the rear tyre, hard centre, then medium till soft towards the sides.

 

Thought of trying them, but i think they cost above $500.

 

Btw, when u watch racers do it, like MotoGP for an example? their tyre profiles are different from ours. Example, we're using 180/55 or 190/55 for the rear. I think theirs are 200/60 or even bigger.

These tires seem very suitable for PG..I noticed the most wear on the tires after practice at PG is in between the center and sides..

 

So a medium compound in between that area can last the tires longer at PG maybe??

$500? i have check with ah boy, he quote mi $300 over. can buy there but dun change there.

 

is dis tire good for track?

sticky enuff and soft??

anyone has tried it b4?

pls leave a msg

[kingpet47]

well ive tried d aftermarket bt014 b4 n its quite good n also sticky... nvr tried d 016 tho.....

I think that alot of people here are forgetting that different tyres have different characteristics depending on compound, operating temperature and carcass.

 

You cant compare one tyre to another simply by putting air in it and riding. Different tyres like to be ridden differently and depending on the rider and his style, he may go faster on one and the other.

 

To me, the fun is in changing your style to suit the tyre, taking advantage of it's strengths. For example, Michelin rears are superb for corner exits - they spin without stepping out much but can be a little muted in the feedback department, so square off corners and drive out. Metzelers fronts are super stable and provide great corner feedback, but in my opinion step out further than Michelins when they spin on corner exits, so take a classic corner speed race line and carry momentum.

 

Pirellis - Have not used them in a long time.

 

However I feel that alot of people dont understand that you cant just out in your friend's tyre pressures and ride. The whole point of reducing tyre pressures for track riding is to stop it from overheating. A tyre has an operating temperature and if you exceed it/dont reach it, it's going to feel like crap.

 

Take a good look at how hard you ride and dont quantify it in "feel", but hot tyre pressures - what the pressure is when its hot and you just pulled in to the pits.

 

I have seen many a beginner rider (me included) ask a super fast guy (because he must know his shizz right?) what pressure he is using and put that in his bike. In the end it feels like **** but we convince ourselves that this is how it must be cos the super fast guy is using this right!!???

 

Wrong - Let me explain, the super fast guy may start off with 30 psi (cold) but rides so fast and hard that when he pits in, his hot pressures may be up to 38 psi! (I've seen this before). But the beginner may also start at 30 psi (cold) but because he does not ride as fast, pits in with 32 hot psi's. The fast guy generates enough heat for the air to expand and give the tyre the right stiffness whereas the beginner never generates enough heat, so he's riding around on tyres that will fold, slide, and handle like crap because he cant generate enough heat to get the air to expand to give the tyre the right stiffness.

 

So in the end, the beginner will think that the super fast guys are freaking Gods - "how the hell does he go that fast when the bike feels like this!!???"

 

Which explains why some people here have been complaining that certain tyres dont last as long - you're using the wrong pressures for the wrong tyre!!!!!!!!!!

 

Metzelers use steel belted carcasses which generate more heat so you probably need to run slightly lower pressures, Michelins have a different belting construction and use kevlar, which generates less heat which in theory means you can start off with higher pressures - but dont take my word for it since the sidewalls may vary in stiffness compounding it further so - got out and try it!!!!!! tyre pressure takes 20 seconds to adjust at the track!!!!

 

For example - alot of people here say that Michelins dont last long, but in MSS 2007, Kawasaki Mayalsia had to run the hardest compound Pirellis (SC3s) to help the tyre last 2 races when Msportbike was running their softest compound Michelins (Power Race Soft)!!! So you want to tell me Michelins cant last???? Now this is not about which tyre is better than the other but using any tyre properly - you need good foundations and set up!!!

 

The fast guys will never tell you this since they want you to stay slow - kidding

 

Always check your tyre pressures and your riding habits before you attack the tyres/bike/suspension.

 

There is soooooooooo much difference a rider can make on a bike, which is why bikes will always be more challenging than cars and motorcycle riders can almost always drive fast whereas car drivers pee in their pants when the ride a bike.

 

Hot pressures are as important as cold pressures.

 

For argument's sake, I was using a 180 rear and 33 psi front and back in the below picture.

Sound advice Mr Harttheracer!!!

 

Next question..how and where to find the optimum tire operating pressure for these tires?

[zzback]

Hartholomew Mamola long time no see!

[Hartholomew]

practice mate.

 

There is no one set tyre pressure for everyone, ride, ride, ride and ride some more, experiment and see what tyre pressure you like.

 

Don't try - don't know.

juz top e gas ler bro at racewerks...y?? u using??

[Hartholomew]

If you know you're preffered "hot pressures" then that would be the pressures you should use with nitrogen, since nitrogen is an inert gas and expands much less than normal air for a given temperature.

 

Being an inert gas and having it pumped in your tyre from a cyinder gives you less impurities, so there is much less moisture and stuff in your tyre to create a chemical reaction. This keeps your rubber better for longer, but the tradeoffs in price and availibility are almost negligible in present times.

 

But, air is 78% nitrogen anyway... so what I am asking is... what's the big fuss unless you are racing professionally? The only people I have seen using nitrogen in our region is a car team that races the Japan GT.

 

If you use common cold pressures like 30 psi.... you are going to be in trouble. the tyre will never heat up like air would and you would flop around on the track with tyres that are essentially... under inflated.

 

My suggestion is nothing less than 34 psi using nitrogen. I would personally go for 36 or 37 psi, because I know personally that those are the pressures in my tyres when I pit in after a hard session using normal air; and since nitrogen almost does not expand at all, that would be the best for me.

thanxs for e clear details and theory..aniwae not making a big fuss over it. juz wanna to make sure dats all... for ya advise.

[Hartholomew]

Did not direct that at you, but meant it generally.

[NightPhantom]

seriously... i noe nuts abt tires and air pressure... but thanks for the info that u provided... its hugely useful for me... why?

 

coz i'm planning to take my bike to track soon and i asked my friend what psi he pumped, den he said 30/30... i was like HUH!!!!!!

 

he's abit mad at track and hitting below 1.50, hence now i understand why the need for lower pressure during track... i'm a newbie for a class2 bike.. so i guess i'll pump around 35..... try first.. anyway not gonna push and see how it feels...

 

anyway i'm just someone who appreciate what you typed. A big thanks!

Hi, wondering there is anyone out there who can feedback to me the wear rate of metzeler Racetec? I bought a brand new pair and went to PG for a ride. I took a 2hrs session and rode for it for about 20 laps. The front then start to loss grip and i went into the pits to check and the front tyres were almost gone! I was using psi 30 on the front wheel. Am i using a pressure too low? I was using 29psi at the rear and the rear still left quite a bit. Or is it suppose to be lidat?

If last time u never had problem with front lossing grip then it shouldn't happen now unless u made big changes to the front like oil, spring rate, valving, valving lose pressure etc. 30psi is good.

hi i bought mine K2 few mths back and used for 4 sessions b4 i feel the rear sliding. i also use my bike for daily commute. PSI is 30 30 on track. how do u feel the front tyre loss grip?

[Wen gege]

Had a Pirelli Diablo Supercosa on my current bike usage, been to track and the fed back is good. warm up fast, grip is taking place. worth the money

I used K2 as well. I'm using 31 psi both front and rear.

I'm quite surprised that u mentioned that u're front is almost gone.

Because my front still looks good. i did nearly 20 laps in an hour.

 

Just a thought, front tyre sliding may be caused by several things.

I felt my front slide before, and i feel its becuz i entered a corner to fast, and i didn't crack open the throttle early enough as i was suppose to, which puts more weight on the front which can cause it to slide.

 

Maybe due to an incorrect suspension setting which causes rapid tyre wear?

[Corse]

hi i bought mine K2 few mths back and used for 4 sessions b4 i feel the rear sliding. i also use my bike for daily commute. PSI is 30 30 on track. how do u feel the front tyre loss grip?

 

 

K2 are semi slicks and the heat cycle is different from Street tyres.

What i heard from a Mechanic who rides on the track too, is that...

Try not use Semi Slick tyres for more than 3 heat cycles. When it heats up on the track, then cools down when u're resting at the pits, is 1 heat cycle.

After the 3rd Heat cycle, the tyre may not perform well as it did on its 1st cycle.

[jeffchua]

If last time u never had problem with front lossing grip then it shouldn't happen now unless u made big changes to the front like oil, spring rate, valving, valving lose pressure etc. 30psi is good.

 

It didnt loss grip in the start due to fresh tyres. But when the front is almost used up, the bike was unable to hold the line when entering into the corner. So tendency of running wide.

When u r entering a corner, u countersteer the bike to lean the bike. When ur front loss grip, the front will STEER INTO THE CORNER meaning to say the handles will steer towards the turn and u will feel ur front sliding outwards especially at tarmac with rips. Bike will also have a tendency to run wide when entering the corner. U will not be able to hold the line u intended.
