cars out of 52 take 36 by 4 single solid tires for front wheels and 

 36 by 7 single solid tires for the rear wheels ; 5 cars, 36 by 6 single 

 solid front and 40 by 6 dual solid rear ; 4 cars, 36 by 5 single solid 

 front and 40 by 6 dual solid rear. The other 33 cars use twenty- 

 six different sizes or combinations of sizes, ranging from 38 by 7 

 pneumatic and 38 by 4 solid to 32 by 2yi solid for front wheel 

 tires and 42 by 12 solid and 42 by 9 pneumatic to 32 by 3 solid 

 for rear wheel tires. 



One reason for the lack of uniformity in tire measurements is 

 the great diversity in size and carrying capacity of the trucks, 

 one being rated at lYi tons, 12 at 15 tons, 18 at 354, 11 at IVz, 

 10 at 2, with cars of every intermediate and smaller capacity 

 down to l.UOO pounds and 750 pounds.

THE NEED OF TIRE STANDARDIZATION. 



.^n analysis of the size of the tires used on the cars described 

 in the "Handbook of .\utomobiles" shows how far we are from 

 standard sizes, though the majority of the passenger cars use 

 tires that differ less than an inch from each other. 



On all the pleasure cars the front and rear wheels are of the 

 same size and out of 151 pleasure vehicles 35 have wheels with 

 tires 32 by 4, 20 measure 32 by 4^, and 27 measure 33 by 4. The 

 other measurements given are 35 by 5, 11 cars; 34 by sVz, one 

 car ; 34 by 4^. 24 cars ; 34 by 4, one car ; 33 by 5, 12 cars ; 33 by 

 4^,. 5 cars ; 32 by 3^, 4 cars ; 31 by 4, 5 cars ; 30 by 3K'. 6 cars. 



The variety in the tires of commercial trucks is far greater; 

 out of 77 trucks, 25 have front and rear tires of the same size, 

 and of these 7 take tires 36 by 5, with front wheels single solid 

 and rear wheels dual solid, while two have single solid tires 

 36 by 5, both front and rear. Si.x trucks take size 36 by 4, front 

 single solid, rear dual solid; six have pneumatic tires, one 36 by 

 6, two 35 by 5, two 34 by 4K>, and one 31 by 4. The other sizes 

 of solid tires for cars with like front and rear wheels are 40 by 6, 

 36 by 7, 36 by 6 and 33 by 4, one of each. 



With a few exceptions, in the case of dissimilar wheels, there 

 are as many varieties of tire combinations as there arc cars. Ten 



WESTINGHOUSE EMPLOYES INSURED. 



An insurance policy for $500 will be given entirely without cost 

 to every employe of the Westinghouse Electric & Manufacturing 

 Co. who has been in the service of the company for a period of 

 six months or more, according to a plan effective March 1, 1920. 

 In addition, the employes, after April 1, may increase the value 

 of their policies to amounts varying from $1,000 to $2,000, de- 

 pending upon their length of service and continuity of savings. 



.\\\ employes who have been in the company's service for six 

 months or longer and who deposit a sum each pay-day in the 

 Employes' Savings Fund, equal to 2 per cent or more of their 

 earnings, will not only receive 45/^ per cent interest compounded 

 semi-annually on such deposits, but in addition will automatically 

 have their insurance increased to amounts up to $2,000, depending 

 on the length of time they have been with the company. For 

 example, a man who has been in the service of the company 

 for at least 15 years and has regularly deposited in the Em- 

 ployes' Savings Fund 2 per cent or more of his salary is pre- 

 sented with an insurance policy for $2,000. 



.\fter an employe has maintained the required deposits for a 

 period of five years he may discontinue or withdraw his deposits 

 from the savings fund without in any way affecting the value 

 of his insurance policy. 



Tn order to provide for employes who need money and do not 

 wish to disturb their savings and thus affect their insurance, 

 loans will be made by the company to the extent of 90 per cent 

 of ;he amount lo the credit of the employe in the savings fund. 



This plan of insurance is to be made effective at all of ihe 

 various offices and plants of the Westinghouse company and will 

 affect approximately 50,000 persons.
