Bicycle tires

One of the main issues of DIY bicycle issues is tires. Depending on the bike whether racing, BMX, common commuter, to a mountain bike,  tires fitted come in various sizes starting with older racing tires. Theses tires are imperil inches. Tape measures read as much as 28 to 20 inches across just over an inche wide. ( 28, 27, 26, 24 and 20 to be exact ). There are 12 inch ( 1 foot ) children's bike tires.

Metric tires read 50 millimeters short of 3/4 meter ( 700mm or equal to 70cm to be exact ) and about 25 to 45mm wide a smaller diameter than the 28 impearl inch which is larger than 26 inch with 27 between. Metric tires my look the same size as a imperil but are that much different Metric tires won't fit impearl rims ether to big, or two small. Measuring inside the tire is a good indicator of the diameter of the rim deigned for. Checking the diameter of rim the will agree. The diameter of your tire is printed on the tire wall, the x by the width in impearl inches or metric millimeters 

Soft tires tend to offer a maximum amount of road rolling resistance. Weight carrying compresses the tire spreading the ball giving the maximum amount of road rolling resistance. Tight tires has the minimum amount offering glorious glides. Condition plays a large part of this.

Tires that have old glass cuts from previous punctures leak air from leaking inner tubes leaking like a sieve. Expanding cuts effect the ability to hold in air. Expensive tires are made glass cut proof at the same time acting as an extra inner tube. Good well worn but in excellent condition would have been an expensive tire when new. They are much better at inner tube air leak containment quality, robust and durable, not easily effected by heavy ware and tear good for many many kilometers of trouble free cycling than budget tires.

Inner tubes also come in budget standard and more expensive puncture proof. A combination of the two insures trouble free cycling for some time. Leaky inner tubes are caused by previous puncture repairs leaking.

Budget new inner tubes and tires are standard not made flat proof tending to leak air accelerated by leaking inner tubes. When older specially with old glass cuts in the tire continually expanding and leaking inner tube begin the habit of leaking air all the time during riding. New should last for a while before the ware and tear starts to take it's toll and if the added complication if old expending glass cuts start to become uneconomical to fix the constantly recurring flats any more.

Slow leaks is a common occurrence. The inner tube starts developing strange pin holes that are notorious suspects and hard to find and repair due to the condition of both the inner tube and leaking tire specially  if there is any expanding glass cuts. The frequency of repairing flat and puncture repair failures start to be become common.

Attempting to fix the problem with budget inner tubes is not only expensive way to fix the problem but the tire old tire condition hurts the new inner tube soon back to square one with staying inflated problems.

A sign of budget tires bike glides feel spongy due to soft tires not lest offering a high road rolling resistance. The problem is due to the tire constantly leaking air as we ride. Budget new standard ones appear hard as a rock pressing with our fingers but as they get older their firmness starts to go all the time leaking air giving higher and higher road rolling resistance due to the weight of the rider spreading the tire. Soon the glide become not as gratifying as it once was when new due to letting the tire get to soft to often.

There are many experiences of tires stating the habit of quickly going soft with increasing frequency specially soon after topping up with air. Even a brand new expensive tire will let you down when a patcy inner tube is leaking like a sieve.

Frequently topping up is a sign of the inner tube leaking the tire leaking as well. There are experiences of tires with on going habits despite new inner tube replacements. It is a sign of not a flat proof tire inner tube and tire bound to have been a standard budgets when new. New expensive flat proof inner tubes can collect a number of patches very quickly with a warn out standard budget tires. The tire is not holding in the air. Eventually hours after repair and top up the tire is totally soft to completely flat again.

For bets result new flat proof inner tube and tire will work wonders in long reliability. 

Inexperienced commuters end up scratching their heads with the tire problem of what's going on and what to do when a tire won't stay up while it is the inner tube and tire leaking air as fast as the top ups.

Riding constantly on soft tires not only offers a lot of road rolling resistance also hurts them wearing out even expensive flat proofed tires very quickly the beginnings of frequent flats. If we are to avoid constant flat problems flat proof inner tubes and tires together work wonders.

Under inflated flat proof tires pressure are as equal to the maximum of correctly inflated car tires, 30 pound spar square inch ( metric kg per square centimeter or bar equivalent if you like ). Rolling resistance of racing bike tires can be as much as a 100PSI. Standard budget commuter bike tires and inner are at lest 65PSI. The average for a car is about 25. Professional athletes can afford expensive flat or air leak less ) proof inner tubes and tires fitted to their bikes.

The pressure information is printed on the tire wall along with the tire size. Standard budget tires range from 60 to 70PSI. Expensive flat proof tires a minimum of 60 up to a 90. So if you want an effortless glide and trouble free punctures fit avoid tires with old glass cuts, consider flat proof inner tubes and tires inflated between the minimum and maximum tire pressure markings on the tire wall.
