Premium Tyre Service Mecacycle Australia Bowral 1-Quality Italian wonder valves core and caps. 2-Free nitrogen filling (normally cost $65) –if 4 new tyres mounted Q: Is there any advantage to using nitrogen instead of compressed air in tyres? Will I notice improved fuel economy or a smoother ride? Will my tyres last longer? A: Sort of. From the top: Air is 78 percent nitrogen, just under 21 percent oxygen, and the rest is water vapour, CO2 and small Concentrations of noble gases such as neon and argon. We can ignore the other gases. There are several compelling reasons to use pure nitrogen in tyres. First is that nitrogen is less likely to migrate through tyre rubber than is oxygen, which means that your tyre pressures will remain more stable over the long term, as the tyres heat up Passenger cars benefit from the more stable pressures. But theres more: Humidity (water) is a Bad Thing to have inside a tyre. Water, present as a vapour or even as a liquid in a tyre, causes more of a pressure change with temperature swings than dry air does. It also promotes corrosion of the steel or aluminium rim. if I ever need to top off a tyre when Im out on the road, Ill always briefly depress the tyre core valve with my thumbnail and vent some air. If my thumb gets wet, theres water in the line. Some gas stations dont do a very good job of keeping the humidity out of their air system How is water relevant to a nitrogen discussion? Any system that delivers pure nitrogen is also going to deliver dry nitrogen. Filling tyres with nitrogen involves filling and purging several times in succession, serially diluting the concentration of oxygen in the tyre. This will also remove any water. Its certainly simple, although time-consuming, for a tyre technician to fill and bleed tyres. But most shops use a machine that not only generates almost pure nitrogen by straining the oxygen out of shop-compressed air, but will also automatically go through several purge cycles unattended. Some shops have been charging as much as $30 per tire for this service. I think thats too much. If youre buying a new tyre, it should be far less. Still, the nitrogen generator, filling system and technicians time arent free—the dealer is entitled to some return for that. So, to answer your specific questions: With nitrogen, your tyre pressures will remain more constant, saving you a small amount in fuel and tyre-maintenance costs. There will be less moisture inside your tires, meaning less corrosion on your wheels. You will not be able to feel any difference in the ride or handling or braking, unless your tyre pressures were seriously out of spec and changing to nitrogen brought them back to the proper numbers. 3-Premium Balancing Haweka pro balancing flange plate System. Flange-Plate – a method of securing and aligning an assembly on a balancing machine is the Flange-plate method. A Flange-plate is added instead of a pressure cup.For more even mounting pressure. The wheel/tyre assembly is mounted to the vehicles hub in a manner that allows the Radial Force high point of the assembly to be neutralized by taking up the inherent clearance in the wheel-to-hub mating surface. 4-Back Cone – Most original equipment and steel wheels can be mounted properly using this method. The wheel is centered on a cone from the inner side of the wheel. 5-use of appropriate wheel weights for wheel types alloys, steels, FN Jap. Matching new weights for correct mounting on correct wheel type .No fly offs 6-Each wheel mounted back on hand torqued at correct torque setting not rattle gun. 7-inside of wheel reference points cleaned for more accurate balance. 8-optimization of tyre/wheel match- mounting The tyre is positioned on the wheel so that the low point of the tyre is matched to the high point of the wheel. This procedure is also referred to as match-mounting. I have made this list up to try to explain what is involved with wheel/tyre changing and balancing. Some may only see the bottom line but it takes 1 hours+ per corner to remove refit balance a wheel/tyre. It also takes top quality equipment and also a lot of training to operate it correctly to get the best results for your car.
