SEVEN INCH PNEiniATICS. 



Just what the limit in size of pneumatic tires is going to be 

 it might be difficult at present accurately to prophesy, but that 

 the tendency is towards larger tires for hea^'y vehicles there it 

 no doubt. Some recent tests have been made with 7-inch tire» 

 on cars weighing, with load, lYi tons, and the tests have proved 

 very satisfactory. The larger tires have several advantages. In 

 the first place, there is a bigger expanse of rubber to grip the 

 roadway, which reduces the tendency to skid ; in the second place 

 there is, of course, more resiliency in a 7-inch tire than in one 

 half that size, as a 7-inch tire means a 7-inch air cushion around 

 the rim. With a larger tire it is possible to have a lower air 

 pressure which decreases the liability of blow-outs. As against 

 these advantages is the greater initial cost of the larger tire, 

 which calls for a greater quantity of rubber and other material* 

 — but the advantages seem to outweigh the disadvantages.
