DETACHABLE RIMS.

METHODS OF HANDLING. Use of the Lever. The detachable split rim is used ®n probably more than half the cars Jn use at the present time, mainly because df its cheapness and not because of any superiority which it over other forms of wheel equipment. Much trouble can it bring to its owner if he attempts to take

a tyre off in an improper way, but V" actually it is not nearly so trouble- / : tiresome a fitting' as many people would have one believe. In removing a tyre the first thing to do is to break the joint, and, although one may eventually achieve this by prylug about' with a stout screwdriver, the best method to follow is to place a block of wood on the floor and J

drop the deflated tyre and rim on to it vertically, with some force just to one side of the break and on that portion of the rim which is designed to fold in over the other. It is then quite a simple matter to contract the rim with one of the many excellent tools on the market, but it is worth pointing out here that a tyre can be removed quite easily from such a rim by using only a tyre lever. The lever should be worked between the tyre and rim just at the point where one

•end of the rim has been folded in l 'Y^ over the other, and' working round its contracted portion the whole •of one side of the tyre can be lifted over the head of the rim. Then the ether side can be worked over in the • same way. In replacing the tyre without r. rim contractor the tyre and tube are fitted into the rim first on the end which is outside, and then the tyre and tube worked over with the lever until the whole is in position. The break may be joined by levering the two ends hack into their catches with the tyre lever or a stout screwdriver. By the way, an important part of

the assembly when split detachable rims are used—or any straight-sided p. rim for that matter—is the “ flap,” a length of canvas • which is fitted

jjnst inside the tyre after the tube been replaced. This should never o© omitted under any .circumstances, for it keeps the tube away from the steel of the rim. "When the now popular well-base rim is used the tube should he deflated fully, and the walls pi the tyre pressed together near the valve and pushed right into the well of the rim. This ■will allow the tyre on the opposite side to eqme away from the rim, and if can be levered over the edge, sometimes with the fiingers alone, and invariably with a lever no bigger than a tooth brush if the job is done properly. A tube that is cut badly should pi ways be vulcanised, preferably by

an expert in such matters, but small cuts and pin holes can be repaired successfully with the ordinary tyre | repair outfit or with a small portable vulcanising set. Clean the rubber surrounding the ' puncture thoroughly with both a scraper and petrol and then apply the solution, which should be allowed to become “ tacky ” before the patch is put on. Then the patch should have a weight placed upon it while it is allowed to set.
