The RTM Friction Tester enables to evaluate friction charateristics of tire tread compound on material testing basis, and can be tested in Dry,Wet,Ice conditions on ring shaped road surface.Test is performed by pressing specimen on constantly rotating ring shaped wheel at free rolling conditionm or with slip ratio applied in 0 to ±95% range and measuring the friction force.

• Slip angle:±30°to the tangential line(automatic setting)
• Load:20 to 150N(feedback control by air servo system)
• Chamber temperature range:-10℃ to 60℃
