A tire inner flap is a protective rubber strip that sits between the inner tube and wheel rim, preventing damage to the tube from rim edges, and heat generated during braking. This essential component reduces friction, extends tube life, and helps prevent dangerous blowouts, especially in high-pressure applications and heavy-load vehicles.
LRMT Inner Flaps combine precision-engineered ISO-compliant dimensions with high-tensile, flexible materials for durability in commercial/heavy-duty use. Exceeding standards, they reduce wear/maintenance, ensuring reliable, cost-effective performance across tire sizes.
A high-tensile belt for tire retreading, reinforcing the carcass to restore structural integrity. This cost-effective solution extends tire lifespan, enhances safety, and reduces replacement costs for commercial fleets.
Brand Story
"Every Mile Matters."
On the long roads of Sri Lanka, through the bustling streets of Colombo, the heat-drenched highways of Hambantota, and the winding routes of Anuradhapura, every vehicle tells a story. Behind every wheel turning across this island, there’s a hidden hero: the tyre flap. For over 25 years, that silent protector had a name: Dimuthu. Trusted by mechanics, quietly present in workshops, Dimuthu flaps did their job without fuss, safeguarding tubes, enduring pressure, and absorbing heat. But while tyres and tubes got the spotlight, flaps remained the unsung guardians of the journey.
Then came a new chapter. When Lanka Rubber Merchant (Pvt) Ltd, a name rooted in quality natural rubber, took the reins of Dimuthu, the mission changed. No longer just a product. Now, a promise. With a renewed purpose and a powerful legacy, Dimuthu by LRM emerged, engineered with precision, enriched with Sri Lanka’s finest rubber, and shaped to meet global standards. A product born from experience, built with science, and ready to face the toughest roads.
We didn’t just improve what existed—we reimagined it. Where others used leftovers, we refined. Where others guessed, we tested. Where others stayed silent, we chose to speak up, about the role flaps play, about their value, and about why every mechanic, driver, and fleet operator deserves to know the truth.
That’s why we launched “Know Your Flap”, a campaign not just to sell, but to educate and elevate. Because we believe when people understand the purpose behind the product, they make better choices and better journeys.
Today, Dimuthu is more than a name.It’s a movement in motion.
A product that doesn’t just support tyres, it supports trust. A brand that doesn’t just last long, it goes the extra
mile. So, whether you drive a bus, a lorry, a tipper, or a tuk, remember this: Whatever the Tyre. Whatever the
Tube. Always Dimuthu. Because with Dimuthu by LRM, you’re not just buying a flap, You’re investing in
protection, performance, and peace of mind.
For every road.
For every load.
For every mile.
