FAQ of the tubeless kit. Q1 How difficult is the installation process? A1 You don't need to have a special skills or talent, just read the enclosed instruction in advance and follow carefully. Q2 Should I be worried about the potential of air leaks/deflation after installation? A2 Please read and understand the contents of the installation sheet before attempting to install. When you install it correctly, it will surely not have any leaks. In the rare event there was some installation issue or damage causing an air leak we have included repairing tape. Q3 How can I remove the bumps of the welded rim?

A3 Even if there are bumps, usually that it does not cause any leaks. However it is recommended to remove the bumps. Q4 Is there any way to check success of the installation prior to using the wheel?

A4 Immediately after installation, the adhesion of the tape is not at full strength, so take care when fitting tire on the rim. Q5 what kind of durability/life can I expect from my Outex tubeless kit? A5 The durability/life of the main tape used in our kit is subject to many variables, however as a guide in outdoors usage it is about 5-10 years provided it is not exposed to UV for extended periods of time, Because of its intended application area on the internal of a wheel rim and therefore removed from any UV exposure the expected durability (assuming no damage from user) is excellent and towards the upper end of the time frame previously mentioned. Q6 How can I repair or replace damaged spokes?

A6 By rotating the nipple you can remove the spokes, if you can't remove some parts of it. Please cut the protection seal and the double sided tape around the nipple in question, then after removal and replacement of the spokes be sure to put a seal and double sided tape again for the new spokes repair area. Q7 If there is rain or if I would have a car wash is there any possibility for the water to get in to the tire. A7 There is almost zero possibility for the water to get in because of the adhesive tape strength and the air pressure. Q8 After installing my tubeless kit is it better to use tubeless tires?

A8 Basically we recommend you to use the tubeless tires, but some users are also using the tube type tire, and there is no report such as air leak. But the usage of the tube tire doesn't have any guarantee. But our company and our professional riders (many ex-factory racers) did extensive testing in extreme conditions and there was no air leaks at all. However after simulating an air leak if there with a tubed tire we could resolve with use of bead sealer. Q9 Is it better to remove the notches of the bead?

A9 We do not recommend to remove the notches. Q10 If the spoke nipples are big and protruding. Will it be a problem?

A10 When nipples are big we recommend you to scrape the head of the nipples as in the below image, it will make for easier kit installation. After having scraped them, please remove the burr or edges. The difference between WM type and MT type of the rims. Image A WM type rim. Image B MT type rim. The WM type is in the shape shown in image A, and the MT type is in the shape shown in image B, the so-called normal tubeless wheel with a hump. In general, the role of a hump is to restrain the tire bead part in order to avoid bead drop when air leaves the tire, but as seen in the image below, if the air pressure is such that normal driving is possible, the bead part does not directly touch the hump, meaning that in the end the tire and wheel are joined together due to air pressure.

The weight of the bike + the body weight of the rider + the traction while driving cause the internal pressure of the tire to increase, and the beads become less likely to drop the more the tire is pressed against the road surface and flattened. As you can see in the image below, during cornering the wheel is weighted by centrifugal force on the outside, maintaining the tire's grip, meaning that the rim is pressing the bead part of the tire in the direction of the white arrow. The rim is pulling the side wall, and the side wall does not stretch, so the outside bead part is not burdened due to the deformation of the tire tread shape. This driving image is from the Tsukuba Circuit, and the tire incorporates an OUTEX tubeless kit.

The air pressure at this time is set at 1.2kPa (17psi) cold, and the results of the race were a win and the establishment of a course record. We have also seen results where the WM type rims on employees' super-cabs and Z-1s have been made tubeless and driven more than 50 kilo meters round trip every day to work for years with no problem, SR400 normal rims (WM types) have run for test in circuit, and DRZ50s and CRF50s with WM type rims made tubeless have won in mini-bike races. This is largely due to the fact that the bead part adheres solidly, making the wheel and tire join together, even more than the reduced unsprung weight caused by the lack of a tube.

With tubed tires, there are places where the bead part of the tire and the bead part of the rim do not adhere to one another, making it difficult to feel the sense of contact with the road surface, and also causing the tire to rotate if there is no bead stopper (rim lock) when driving off-road. Whether tubed or tubeless, the causes of WM type rims experiencing bead drop are the air pressure being extremely near zero or something causing the tire to leak air when the bike is parked. Considering punctures, when a tubed tire is pierced by a nail, etc. With tubeless tires, in most cases you can keep driving as it is even if pierced by a nail, etc.

In other words, the speed at which air leaks is slower with tubeless tires, making their safety factor exceptionally higher. In rare cases air may gradually leak even with tubeless tires, but as the air pressure drops the handlebar will become harder to move and you will be unable to keep riding, so you could notice the problem immediately. Due to the above facts, if you maintain regulation air pressure, we think it is safe to say that there will be no difference between WM and MT types as well as no fear of bead drop. However, when the bead part has become rough it is necessary to repair it to a clean state, and it cannot be said to be safe with all rims, so some workmanship is required.

The reason OUTEX tubeless kits have spread not only across Japan but also overseas is that they work with no problem with WM type rims as well as long as they are installed properly. Incidentally, this kit has been on sale for 9 years now and there has not been a rim that couldn't be installed on. Assembly method for tires with WM-type rims.

The fact that the OUTEX tubeless kit can also be used with WM-type rims without any problems has become well-known, and recently it has become common-place for adventure-type KTM990 ADVENTURE or CRF1000L Africa Twin / etc. Front 21-inch rims to be changed to tubeless as well. However, caution is required when assembling the tire after executing the kit, because if you attempt to insert the tire with all your strength using a tire iron in some cases the protective seal which is not yet stuck tightly may peel off. When assembling the tire you must be careful to make sure that the tire's bead part does not hang on the protective sheet. It is important that the tire bead on the side opposite the side you are attempting to inlay the tire into with a tire iron is set into the center of the rim, so when doing the work alone, if you either insert the tire using screw clamps as in the following image, or use a large clamping band to prevent the tire bead from opening, it is possible to inlay the tire easily without damaging the protective sheet.

Attempting to force the tire together with the bead of one side of the tire off center from the rim will result in damage to the protective sheet. By putting air in the tire after assembling it with tire bead in the center of the rim the protective sheet will be set into position into the bead of the rim while pressing the protective sheet into the rim. The next time the tire is changed, the internal pressure will cause the protective sheet to adhere firmly, so the tire can be changed as normal. But you should still please use bead cream.
