The tires of the Talos S 2-in-1 are made of rubber filled with polyurethane. PU-filled tires are exceptionally durable, resistant to high temperatures, and need less maintenance or repair when travelling on different terrains compared to other types of tires. PU is harder, firmer and heavier than comparable fillings such as EVA while also being more flexible. This means that it keeps its shape while travelling over bumpy ground while also acting as an effective shock absorber. Puncture-proof and able to handle rough and uneven surfaces, these tires are a good choice for parents who want to travel in the outdoors.
