Informative Speech On John Boyd Dunlop Tires

John Boyd Dunlop

Specific Purpose: To inform my audience about the significance of the invention of pneumatic tires by John Boyd Dunlop.

Introduction:

I.Attention Getter: Not 5, not 10, but more than 200 raw materials are used to make one rubber tire.

II.Relevance to Your Audience: According to a report by the Rubber Manufacturers Association(RMA) in 2003, it was found that approximately 330 billion tires were produced every year in the US alone and their report stated that every fifth car in the US used Dunlop tires.

III.Speaker Credibility: Through my research of various websites like inventors.about.com and books like John Boyd Dunlop by Jim Cooke.

IV.Thesis statement:In 1887, Dunlop invented pneumatic tires because of his son’s

minor health issues but he did not expect it to become one of the most significant inventions for the development of road transport.

Transition: First, I would like to tell you how and why John Boyd Dunlop developed the Dunlop tire.

Body:

I. Main point: John Dunlop was keen to develop the pneumatic tire due to his son’s health issues.
A.Supporting point : He came up with this idea after his son was prescribed to ride his tricycle everyday as a cure for the bad cold.

Directional Transition: Now that you know how and why Dunlop came up with the idea of pneumatic tires, I will tell you how this idea came to have vast significance.

II.Main point: This invention of the tire came at a very crucial time in the development of road transport.

Supporting statement:
A.This invention was beneficial to road passenger travel as the rubber tires made the ride comfortable and less time

consuming.
B. Road transport was the most efficient way to move goods(raw materials and finished products) from one place to another.
a. It contributed to the development of the national market economy in the UK and other European countries.
b.Rubber tires made the movement of commercial vehicles more cost effective and safer.

Transition: As I have hopefully shown, the Dunlop tire was a very important invention.

Conclusion:

I.Review of Thesis: Specifically, I have told you about how and why dunlop invented the pneumatic tires and how significant his invention was to the development of road transport.

II.Summary of Main Points: John Boyd Dunlop came up with the invention of the century-The pneumatic rubber tire.

III.Clincher: This important invention that changed the international economy was the result of the common cold.
