Trial tyre IRC TRIAL TR-011R 4.00 R 18 M/C 4PR NHS TL rear

IRC offers this trial tyre. In trial, you climb over rocks, steps and logs at low speed: the tyre has to wrap around the obstacle instead of bouncing off it.

Why a dedicated trial tyre?

The benefits:

• Far more grip than a motocross tyre on rock, roots and steps, thanks to the flexible carcass and soft compound.
• TL: no tube to pinch, so you can go very low on pressure; TT: conventional fitting, but the tube can get pinched at low pressure.
• On the other hand, the soft rubber wears quickly on tarmac and the tyre is not made for high speeds.

Why choose IRC?

IRC (Inoue Rubber Co.) is a Japanese manufacturer founded in Nagoya in 1926 that has made motorcycle tyres since 1952. Its TR-011 Trial Winner was developed for trial competition, with a soft compound in the centre and a harder one on the shoulders.

When should you replace the tyre?

Rounded or torn blocks, rubber that is starting to crack, a cut sidewall: it needs replacing. In competition, the rear is changed as soon as it loses its sharp edges; for leisure riding, when grip on rock drops noticeably. A tyre that has hardened over the years loses exactly the grip you expect from a trial tyre.
