IRC Tire is Suck!!!

As you can see in the title, I'm trying to write my upset to this tire manufacturer. I'm using IRC MB-520-m on my scooter, because this is the only IRC tubeless tire sole option for my scooter in Indonesia.

Lets track back my experiences with this tire.

1. Tire Lump
I don't know exactly what time it was. What I know is, I change my rear tire with this tire. I don't have to wait too long before lump appear, about 6000km after I change it.

2. Tire Ripped
Friday, October 12, 2007, me and my wife was riding to a friend house. Suddenly my scooter become unsteady after I heard an explosion. Fortunately I can handle my scooter so we aren't fall down to the grown. I run my scooter to the left side of the street and see what happen.

When I see my rear tire, it had flattened. Whats going on? I check my tire and found out, It Ripped! Whereas I fill the rear tire with 32psi appropriate to the owner manual.

3. Tire Slippery
Saturday, December 22, 2007, about 10pm I rode my scooter alone to home. I know its very late, but I don't have any choice. With no street light at all, I can only count on my scooter head light. Suddenly it happened. In front of me not far about 5 meter, there is a huge hole on the ground. I can't avoid it, it half the street. And on the right side, there is a huge mud truck.

I must slow down my scooter. I hit the brake not too hard and my scooter is slowing down. But suddenly I sense something wrong with the rear. It shaky! I'm loosing a grip on my rear tire. I tried to control it, but it didn't work. I hit the ground!

That is what happen to me, three is just enough for me to judge that this tire is suck.

Lets analyze this tire.

According to the official website, there is MB-520. But when I see it deeply, that is differ from what they sold in Indonesia
And this is the one that IRC sold in Indonesia

These two pattern are different! What is wrong with IRC? Do they change the specification pattern on each country?

Now I'm going to test this tire with a simple test. I spray water on the tire surface to see the water drainage.

As you can see as point the arrow, water drainage is so bad. It block the water on the center of the tire. That will make water floating on the tire.

How about if we use this tire for cornering on a wet surface?

Again, this tire drainage is really bad. It blocking the water while it use on cornering. Dangerous indeed if we keep using this tire on a wet surface.

So, my conclusion for this tire is: IRC MB-520 for my country IS SUCK !!!


  1. If you have possibility to use Batlax then use it... Wuahahahaha... I want it but my wallet not allow me to have it. Btw I use IRC once because it came along with my KX. One thing I remember, the lifetime for this tire is amazing, but contrary with it, the quality is truly suck. The same opinion like what om ai said before.

  2. There is no Bridgestone Battlax for 10" wheel. I'm planning to import Bridgestone Hoop or Bridgestone Scooter. Just wait and see 'till the day come.
