This is Mike from China. Our company are specilzing in export of all kind of Chines tires mainly TBR,OTR.
We produced TBR in Sailun factory that is very very big factory, its parent company is a public company in China. We produced tires in OEM at factory mainly for TBR(TTF) The quality is realiable.
As you know, the price of Chinese tires kept increasing recently due to skyrocketing of price of raw materials such as natural rubber,steel,etc. So, you could find that attached price is relatively reasonable compared with other Chinese brand.
By now, we could supply around 25x40HC for 1000R20 and 1100R20, hope to get your soon reply by then.
Look forward to hearing from you soon.
