'D|ACNOSE" TIRE
 FUR REPAIRING
JUST LIKE DOCTOR DIAGNOSES
 HUMANS,
lBE |. C. Sauflev.A

Diagnosing the troubles of sick tires is in it's way TO less a profession de- manding skilled training than diagnos ing the troubles of sick people, said Bob Saufley of the Saufley Rubber company. IL is q trade that demands a great deal of skill and training lo be able to pick out unerringly in a tire every damaged and weak place in the fabrlc or cOrds. Many an autoist has thrown away tire that might have ; been repaired or retreaded and given thousands of miles more service. and Likewise many an autoist has paid good money for q repair or retread lob on a tire that was not worth the expense and should have been sold for junk
 Before our VulcaniZing department undertakes the repair of retreading of a tlfe, our shop foreman goes over that tire thoroughly and diagnoses it's troubles to make sure that the tire will slNe mileage to justify the expense of the repair or retread and if there is any doubt in his mind as to the serv- Icability of the tire after the repair. he turns the job down and We refuse all repairs on such tires.
 We have done a great deal of eX- perlmental and research work in our repair department during the last four years to determine the best compounds for use in this country over our rough roads and to know which fabrics and tread rubbers will stand hard usea ge the best This work has been expensive but the results have more than iusti- lied the expense.
 Also we have used all methods in our retreading department, both the Kettle, one cure process and the Dri cure process. As d result of our cX- periments with both methods side by side, we some time ago discontinued the use of our kettle method and sold our equipment at a large loss, as we were convinced that the Dri cure method is much superior; it makes q much denser tread; is capable of very much greater pressure during the cooking process thereby impregnating the rubber more firmly into the carcas of the tire: looks much nicer; in fact, one can hardly tell from the looks a retrcad by this method from q new tire, and, finally, the Dri cure does not cook the beads or side walls of the tire at all, and we found that in the kettle cure most all the side walls or beads would get spongy or break loose very easy
 Don't start or stop quickly. If you do you put strain on your tires. and they are one Of the most expensive items of car operation.
 Don't turn the corners at high speed, 1t puts tremendous strain on vour tires.
 Don't travel too fast. The slower you run the smaller will be your re- pair bills.
 Don't run in car tracks or ruts. The rubber on the sidewall is not intended for wear, but as a covering for the carcas
 Don't leave a bolt or any object on your car protruding where there is chance of it's gouging the tires.
 Don lay up your car with it's weight on the tires. Jack it up, or. better still, remove the tires and store them in cool dry place.
 Don't keep a tire in reserve for any considerable period. Rubber deterior ates and requires action occasionally to preserve its life.
 Don't allow a tire to be applied to T rim on which the bead channel is bent or half filled with rust. It will not seat properly and will likely be short lived.
 Don't neglect your air pressure. in Hate your tires every few days and see that they are up to standard pres sure.
 Don't dismiss these pointers from our mInd without action, but give
