FRIDAY, AUGUST 29, 1919. THE WHYS AND WHEREFORS OF TIRES EXPLAINED BY FIRESTONE DEALERS The following talk on “Tire Facts” has just been issued by the Maynard Tire & Auto company, exclusive dis- tributors for 14 counties of Firestone products: There have been very many refine- ments in the construction of tires in the last few years, and the product that is built with quality as a basic principle of its manufacture is very dependable. Because this is so, the motorist frequently places so much confidence in his tire equipment that he is apt to overlook, so far as his casings are concerned, the frequent inspection and attention which he gives to the rest of his car. The problem is to get a man in- terested before the accident ‘befalls. As a rule we are disposed to wait un- til’ our machines or tires let out a howl before attending to them. ‘A variety of points may come to our notice in this connection. In the first place, the selection of tires is often to blame for subsequent diffi- culties, The correct adaption of tires, whether demountable or detachable or both, to tire, whether straight- side or clincher, should also be studied. Sometimes an inner tube is partly ruined from deterioration be- fore it ever gets out on the road. Lubrication, again. is often too infre- quent, and improperly done. Even the question of inflation is not so|Small percentage of cars, though the ~simple as it may at first seem. As for abuses, unnecessary exposure to the. effect of oil and grease, an all 100° common overloading of’ machine or tire, the sudden setting of brakes, the disregarding of cuts and ‘bruises, the thoughtless attempt to wear down the steel car tracks—these are only a few of the mistakes of which many of us are heedlessly guilty. When tires are loaded beyond their normal carrying capacity, ‘the fabric is more or less strained. Besides, “hinging” action is developed and heat is generated at the edges of the tread. Oversize ‘tires were primarily de- signed for exceptional and hard ser- vice, but have come into more general favor pecausejof extra strength, eas- ier riding, and longer mileage.

Car construction, power, lateral and trac- tion strains upon the tires must be kept in mind when determining the diameter and cross section of tire equipment, but the weight of the tire is probably the most important fac- tor. This can be found almost any- where ‘by running the front half. of the car on platform scales, and not- ing the result. This operation can be performed in the case of the rear wheels, and the same thing holds ttrue. The middle of the wheelbase will be the weight-dividing point be- tween the front and the rear halves of the cur, The approach to the scales sould be level. If reasonable care is exercised. the total of the two operations, that is, the recorded weight of the front and rear parts of the machine, should Se within 20 or 30 pounds of the weight on the car, when all of it is upon the scales, The weight and distribution of.the car, power, speed, gear and’ other points are considered iby the car en- gineers and car makers in determin- ing the tire sizes necessary for equip- ment. It will be apprehended, how- ever, that the treatment demanded by cars will vary on account of road conditions, drivers. and other reasons. Therefore, it is reasonable to expect some trouble from the tires on a equipment on the majority will prove satisfactory in every respect. Application of Tires The careful application of tires is quite necessary as the choice of the correct type. Especially should the best adaption of tire to rim be made a subject of concern. Before applying a tire all rust and other foreign matter should be care- fully removed from the rim. ‘If rust has formed on the rim it will cause trouble at some Slater time, apart from the corroding influence of the rust. If tires have been driven de- flated at any time, mud will probably have accumulated on the rims, and unless this is removed the tires can- not seat or fit properly. The danger of pinching inner tubes can best be soapstone or powdered mica on the rims, so that the tire beads will slip into the correct position easily. Inflate the inner tubes just enough to round them out before placing tubes of the wrong size, and be sure spreaders adapted to the _ particular ouick detachable or straight side. therefore are suitable for use in all inner tube with powdered mica. or When the tires have been removed for some reason, it is a good idea, when reapplying, to reverse them, that is, to place the worn sides of the tires toward the car. It is not very generally known, though it is a fact, that almost all of the side wear on a tire occurs on the outside; that is, on the side ‘away from the car. ho foregoing sounds Irish, I know, but it is a fact nevertheless. This is due to road construction, rut wear, curb scraping, and such things. The life of a tire may be prolonged to such an extent that a great deal’ higher mileage may ‘be secured ‘by turning the tires about occasionally to se-} cure even wear upon both sides. I said that tire and rim should be suited to each other. If straight side tires are to be used on clincher rims, filler beads ought to ‘ve fitted in the rim clincher to keep the side walls of the casings from being chafed and gauged. To avoid as much as poss- ible the tendency of straight side tubes to lift up from the rims at the inner edges of cables and in this way permit a rolling motion sideways, it is advisable to have more spread be- tween the cabled than is necded for beads of the clincher variety. The best way, therefore, to use straight side tires on clincher rims is not to use them at all. The two types don’t mix. Concluding this subject, the import- ance of using flaps should not be! overlooked. Whether clinchers or straight side tires are employed, both rings should be in position. A few folks really don’t know these last two things; more people know them and don’t do them. Handling Inner Tubes What the air container of the bas- ketball or the football is to the whole toy, that, the inner tube is to the tire. Be careful of it and you ride on a first class cushion of air, ‘be careless and you are going to ride all the sooner on the rim and the rocks. If tire users better understood the construction of inner tubes, and, what is more to the point, would put | in practice what they know, the com- fort of riding would be greatly en- chanced. The trouble sometimes starts when the tubes are bought. They come in cardboard boxes to be sure, but that is No reason why they should be kept in such containers any longer than is necessary. There is danger that the gum,—and the danger is all the great- jer if the gum is of the pure Para variety, will be chafed, and eventual- ly cracked and ruined. It is a ma'ter of economy to purchase a tube bag, which soon pays for itself. The value of fresh air may be em- phasized to advantage in relation to tires as it has been in respect to lungs. If your machine is to ‘be “laid on the shelf” for a few weeks, re- move the stale air, pump in enough fresh air to “round out” the’ tubes, cover them against the light, and jack up your car. On general principles, tubes should be filled two or three effect of stale air is in itself the deleterous. Reverting to the subject of. pre- erving tubes in cases, a given size of tube should always ‘be placed in the same size of case. Just as it is |times a year with fresh air, since the}! inadyisable to wear shoes cither too large or small for one’s feet, so is il imprudent to' keep a tube in the wrong sized container. It should be obygous that a 4 1-24nch tube, if stored in a 4-inch case is sure to ‘be- come wrinkled and creased, and it should be equally obvious that a 4- inch tube % a 4 1-2inch case is bound to stretch and get flabby, as well ag to suffer the ill effects of heat and action due to displacement of air; and yet people who are aware that shoes which are too small and shoes which are too large are similar- ly harmful to their feet, will thought: | lessly or persistently ruin their tire} equipment ‘by the kind of perform: ance which I have just suggested. I alluded to the importance of lu- brication, Before leaving the ques- tion of handling inner tubes as they should be handied, let me emphasize the value of lubrication. Care should bo exercised that the lubricant is dis- tributed evenly. If the soapstone or mica, or tale is “dumped” at one spot, surplus heat is generated, which dries the rubber locally and promotes cracking, The same undesirable re- sult comes from using the lubricat- ing too freely; for some people, act- ing upon the mistaken principle that if a little of anything is good, more is better, are inclined to overdo the lubricating expedient. They overdo it just as they injure the lining of} their nostrils by employing a salt solution that is too strong for those tender membranes. Do not minimize! the importance of lubrication, but be certain that the right amount is dis- tributed often enough in the right way and in the right places.
