GOODRICH WIRELESS TRUCK TIRES. 



THE small cut herewith illustrates one of several styles of 

 the Goodrich truck tire which is built up on a steel base 

 without the use of wires. The tire proper consists of three 

 factors; the steel base, a sub-base of bard rub)>iT and tlic usual 

 solid rubber tread. The 

 steel base is beveled and 

 dovetailed on the upper 

 surface. Instead of 

 being an endless ring as 

 in the usual pressed-on 

 type, this steel base is 

 cut through at one point 

 in order to permit it to 

 spread slightly. This 

 allows it to be easily ap- 

 plied to the wheel and 

 then drawn together by 



means of the flanges. This increase and decrease in circuiuferciur 

 is so slight that it docs not aflfect the sub-base of hard rubber 

 The sub-base is indicated by the black portion of the tire in the 

 illustration. It is dovetailed into the steel base and is vulcanized 

 along its wavy upper surface to the resilient tread, the union 

 between these parts Ijeing made permanent so that they cannot 

 separate. This tire is made in a num- 

 ber of styles, such as the demountable- 

 endless fi)rni. the demountablt- ami 

 block furni. the pressed-on type, and a 

 special tire for electric vehicles. | The

SOMETHING NEW FOR THE REPAIR MAN 



Tile illustrations herewith show twi' 

 different forms of a new retreading 

 tire band which has just been placed 

 on the market. The idea of supply- 

 ing a retreading band with a non- 

 skid pattern upon its surface is 

 Sdmething entirely new- and some- 

 thing which should appeal to the tire 

 repair i-nan in all localities. With 

 'iin- III tliesc liands an old tire may 

 be made as good as new, with the 

 additional feature of having the 

 safety tread. Retreading bands have 

 been on the market for some time but 

 the bands shown herewith are the first 

 to embody the non-skid feature 

 These bands are made to fit all sizes of 

 tires and are supplied with a num- 

 ber of different tread designs, n'hc

SPARE TIRES CONCEALED FROM SIGHT. 



M'liere to put the spare tire where it will neither be in tlie 

 way nor too much in evidence has long been a problem. A recent 

 model of the limousine presents a solution of this perplexity in 

 the form of a cupboard added to the back of the car, constitut- 

 ing in fact a double back, there being nothing w-hen the doors 

 are closed to indicate that it is not the real l)ack of the car. 

 This cupboard is shallow but tlie full width of the car. and 

 provides plenty of room for a spare lire and for extra inner 

 tubes, and if necessary for a spare rim. 



Air CusHiox Tire on- 



air CUSHION TIRES FOR PLEASURE CARS. 



.\ peculiar design of rul)l)er tire, built by an English concern, 

 is shown herewith. The tread of this tire, which is known as 

 the "K- r,' may be descrilied as a band of rubber, on the surface 



of which are two rows 

 of cylindrical rubber pro- 

 jections. The tread is 

 made in a long strip and 

 inserted by hand into a 

 perforated rim, becoming 

 the equivalent of an end- 

 less tire. The claim is 

 made that this tire has 

 the resiliency of the or- 

 dinary pneumatic with- 

 out the disadvantages of 

 the latter, and at the 

 same time providing in- 

 surance against side slip- 

 ping. Such a tire can be 

 casil\ repaired should 

 any part become injured 

 through severe applica- 

 tions of the brakes or 

 from any other cause. 

 by removing the tire 

 from the rim and vul- 

 canizing a new section nf rubber in place of the damaged por- 

 tion. [The Commercial Tyre Co.. Limited, Long Acre, W. C,

NON-SKID TREAD AND INNER TUBE. 



.Mthii tne design of the tread projections on the lire illus- 

 irated herewith is somewhat new in form, these fill the same of- 

 fice as tlie styles on the usual l\pe nf non-skid tread. They are, 

 however, built 

 so as to grip 

 the road at the 

 point where 

 most needed to 

 guard against 

 side slip. The 

 tire is built up 

 m the usual 

 manner, w i t li 

 six layers of 

 1 a 1) r i c and a 

 breaker strip 

 upon which the 

 tread is vulcan- 

 ized. The non- 

 skid elTect is

double row of Xs molded on the surface of the tread, thereby 

 producing two rows of diamond-shaped clips which grip the 

 surface of the road in all directions. The makers of this tire 

 are also producing a new inner tube w-hich is provided with a 

 ring of reinforced fabric on the side that comes in contact 

 with the beads of the tire casing. This does away with the 

 separate tube protector and eliminates tube pinching. [Mo-
