Longtime seller High gripBias

This stock is an unusual longtime seller for SportsTire
My memory is fuzzy, but I think it was released in 1994 or so

The old car High grip TT100GP still in service
The TT300GP, the favorite of 80's mountain bike riders, with a slanted pattern
The normal evolution of the TT500GP
TT700GP & larrr in a strange tread pattern; I used it on my R1-Z at the time
The TT900GP is the real successor to the TT500GP
So, the TTSeries is
Dunlop's scribes - it's the history of CircuitUser itself!

Now for the feel
I don't know about Grip on the street, but of course enough
The cross-sectional shape tends to be sharper than the BS BT39 and looks thinner

Before using this, IIRC, I had an RX-03 spec-R on my car, and in comparison to that
The IRC has better straight-line performance, and the TT900 has a better feeling of banking stability
I didn't measure the weight, but the TTT900 feels heavier
I feel that there is no difference between spec-R and Large in Life
The TT900GP with the CenterGroove has the same level of change in appearance as the TT900GP with the CenterGroove when it is reduced (It's a loss) impression

The rumor of the next MODEL doesn't come out, but it's not too bad that Circuit is also good looking in the affordable price range I'd like to see this position, called grip, continue in the future

Satisfied with Grip power

Very Good

It is a substitute from IRC SpecR. Although it is used in VT 250 SPADA, Grip force - Both turnability are good impressions.

Because it is only Circuit driving, it may be due to the car type and Setup, but it also receives a little touchdown area on the Middle bank, but the ground contact area at the full bank will be wider or there will be a sense of stability without anxiety.

It is TT 900 GP decision to wear next.

IRC's RX-01spec-r is better

Poor

Oct 2, 2017

It was a change from IRR's 01R.
I am going to run Compound is good I got a feeling that I was steadily kicking the road with straight acceleration, but the cornering limit is too early.
I think that this is not a matter of Compound but a design of Tire itself, but suddenly you lose your Grip ability beyond a certain bank, and SlipDown and Rear will start off as soon as you try to accelerate into a bank. I tried changing the air pressure also with reference and standard ± 20 kpa, but it did not change.
For sliding, Tire begins to melt early and Life seems to be about the same as ordinary high grip tire.
I thought it was a good Tire because it was a long time ago, but it seems it has become a Tire that can not be used now.

I tried it because the reputation was good.

I tried it because it was a touch with the highest grip in Bias. Certainly it is cheap with High grip so you can go and get down. I feel ride comfortably. Due to High grip there was only 7000 km to 8000 km.

I tried it because the reputation was good.

Excellent

It changed from GT501.There is sense of stability of the Corner unique to the
High grip, and it turns out that the Tire is sticky.The
angle of bank is also deep and it demonstrates power to a Sports run.It was thought that it was very easy to treat the
Handling in a Quick.The
Demerit is durability too.
Although it exchanged and ran 1000 km, wear is likely to be early crushed by 3000~4000 km.I think if it becomes
reference.
