What is the use of radial tires in bikes ?
It's better tire all around, better balanced, better material, hold up longer, rated for higher speeds, just overall a better tire.
They provide the friction with the ground sufficient to propel the bike forward when pedaled. The front tire also rotates side to side, allowing the rider to steer the bike.
Radial okorder /facts_7282439_bias-v... Seriously...you could have googled this yourself. Seems pretty obvious by your previous questions you are oblivious to ANY knowledge of tires... BTW....an answer to one of your previous questions.....The MAJOR use for recycled tires in the US is for rubberized asphalt for roads. I get paid to pick up and dispose of used tires from tire shops. I take them to a recycling facility where they are chopped up, the steel belts are separated and recycled and then the rubber pieces and ground up into "crumbs" that are used to make rubberized asphalt for roads...... swm.maricopa /waste-tire.htm
