What is Road Bicycle Tyres？
Road tyres most often come with slick or smooth designs, as this helps reduce rolling resistance. It also helps increase grip on smooth surfaces, helping keep your cornering speed high.
Benefits of Road Bicycle Tyres
Lightweight
They are lighter than clinchers due to their unique construction.
Ride quality
They offer better grip and withstand temperature changes in the tarmac well.
Lower friction
Thanks to higher pressure, they have less contact with the road, allowing for more efficient progress.
Gradual pressure loss
In the event of a puncture, the pressure drops more slowly, which can be handy for reaching a repair point.
Types of Road Bicycle Tyres
Clincher tire
Most common type requires an inner tube that sits between the wheel rim and tire to inflate and hold air. In case there’s a puncture, riders can easily patch or even replace the inner tube;
Tubular tire
Well known among professional riders due to the performance benefit this tire provides, however, rarely seen being used by recreational bikers as it’s not as practical for daily usage;
Tubeless tire
Almost similar to clincher tire except, as the name suggests, it doesn’t come with an inner tube. Instead, this type of tire has a much tighter tolerance to create a firmer airtight seal. The sealant will be added to this type of tire so it can plug small holes and splits, reducing the chance of flattened tires.
Sidewall – This is the part of the tire where the recommended pressure and the name of its manufacturer are visible. The sidewall has a protective function for the inner part of the tire and determines how it fits on the rim;
Body – This is the part of the tire that is directly under the tread and which provides reinforcement for it. It is made of many thin but strong threads. The higher the quality of the body, the greater their number. Its quality can be checked by looking at the TPI value. It informs about the number of threads per square inch of the body;
Tire bead
Sometimes it is also called the flange – it is a tire element that adheres directly to the metal rim. Based on its structure, wire and coil beads are distinguished. The former contain metal wires, with the help of which the tire is attached to the rim. They are quite heavy, and at the same time cheap. In contrast, coil beads are finished with a synthetic polymer – usually aramid;
Tread
Is the outer part of the tire, finished with special grooves, which is in direct contact with the ground. It is responsible for dynamics, grip and safety while driving;
Anti-puncture insert
This is the foam between the tire and the rim. It reduces the risk of catching a “slipper” and stiffens the tire.
Process of Road Bicycle Tyres
Raw material selection
The journey to crafting a high-quality bicycle tyre starts with the selection of the right materials. Manufacturers often use a combination of natural rubber and synthetic rubber, ensuring the tyre's durability and grip on the road.
Extrusion
In the extrusion process, the rubber compound is shaped into the desired tyre profile. This step involves the use of precision machinery to create the tyre's pattern, sidewalls, and other important features.
Compounding
The selected rubber materials are then mixed with various additives to create the ideal compound for the tyre. These additives enhance the tyre's performance characteristics, such as traction, wear resistance, and puncture protection.
Curing
Curing involves the application of heat to vulcanize the rubber, which strengthens the tyre and gives it the required elasticity. This process ensures that the tyre can withstand the demands of the road.
How to Maintain Road Bicycle Tyres
Tubeless tyres：For the most part, tubeless tyres are fit-and-forget, but you will periodically need to top up the sealant because it dries out over time. Different sealants will dry up at different rates, but it's worth getting into the habit of checking your sealant levels every two to three months.
You can do this either by removing a small section of the tyre's bead and visually inspecting the sealant levels or by inserting a cable tie (with its end chopped off) through the valve core, which effectively acts like a dipstick on a car.
Either pour some fresh sealant into the exposed section of the tyre or inject it through the valve core. Once every year or 18 months, it's worth fully removing the tyre and giving everything a thorough clean to remove any sealant that may have clogged up inside the tyre.
Summer brings good weather, clean roads and the best road bikes out to play, so it seems ludicrous that we would stick a slow-rolling and heavy-duty tire on our bikes.
If a fast rolling tire is your thing, you’ll be expected to have lowered protection from punctures with a thinner puncture protection belt to help reduce weight and rolling resistance, which will help that fast feeling we all desire.
However, come the colder months many riders will opt for winter road bike tires to counter the associated bad weather and gritty harsh roads, to save them from being victims of the dreaded flint or glass puncture. If you're new to cycling, or even a recent returner, it's always good to know how to fix a puncture and mend an inner tube.
Larger tires allow for lower pressures that help absorb the bumps, increasing grip and comfort too. Watch out for mudguard clearance though as larger tires could be limited if you have minimal clearance.
But increasingly, cyclists are steering towards wider tyres and this is apparent in bike design, as most endurance road bikes now take 35mm or even 38mm tyres as standard, and most racier road bikes can take up to 32mm.
When you leave smooth surfaces, wider tyres offer even more significant advantages, as they allow for enhanced comfort and traction. In the UK, roads are filled with all sorts of holes and debris, and it definitely helps to have wider tyres in typical riding conditions.
While tyre width plays a large role in performance, the true determinant of speed and comfort also lies in the quality of the tyre's casing and profile. High-performance road bike tyres with supple casings offer better traction, comfort, and efficiency, regardless of their width, so if you swap for wider tyres, don't only look at the millimetres.
Your wheel rims can have a huge impact on how your tyres sit and even make them wider or narrower - and you might be limited in how wide you can go if you have a narrow rim.
Will I Still Experience Flat Tyres with Tubeless Road Tyres?
One of the main benefits of tubeless road tyres is increased puncture protection, but that doesn't necessarily mean fewer punctures.
However, when an object pierces the tyre, the pressurised air tries to escape through that hole. As it does, sealant is pushed through the hole. The best tubeless sealant will clog up rapidly, plugging the hole and fixing the puncture with only a small loss of pressure. Most of the time, with the kind of punctures you tend to pick up from small bits of glass, rocks or thorns, you might not even notice it happening and can just keep riding along as if it didn’t, although you may find a spray of sealant on your frame next time you wash your bike.
Sealant alone won’t be able to fix larger cuts in the tyre (anything over about 5mm) but what makes tubeless tyres different is that you've not got extra layers of flat protection. Your first layer is the tyre itself but that's the same as a tube-type tyre. Without an inner tube, you avoid many of those roadside repair jobs.
The next layer of protection is the sealant, which is usually enough to solve the problem. If your tubeless sealant fails then your next step of puncture protection is a plug system such as those offered by Dynaplug.
How to Mount Tubular Bike Tires
Make sure you have the right wheels: Tubulars tires are not compatible with tubeless wheels and foldable tires, but require specific wheels dedicated to this purpose.
Cleaning the wheels:If the wheel is not new, it is suggested to clean it in the best way possible. To do this, you can use sandpaper, wiping it until all the old residues are unstuck. Finally, it is recommended to wipe with a damp cloth together with the degreaser.
Application of the mastic: Once the wheel is cleaned you must proceed by applying the glue on it. You can help yourself with a brush or a toothbrush, the advice is to do a quarter of a wheel at a time. To apply it in the best way, it will have to be spread all over the inner part of the circle. At this point the wheel is ready.
Preparation of the tubular tire: Take a new tubular road bike tires, inflate it a little bit, just to allow it to take the ideal shape. Then apply the mastic to it as well, and at this point the tire can be applied to the rim.
How to apply the tubular: Start by inserting the valve first, which must be in the upper part. Pull and insert the tubular evenly, both on the right and on the left with the same force, to make it adhere evenly. When the last part is missing it will be the most difficult, but by increasing the thrust it will fit in without problems. Now is the time to check if the tire is inserted correctly and the wheel turns without obstruction. If there is any excess mastic on the edges of the wheel, a good idea is to spread it between the shoulder of the tubular road bike tires and the rim.
How to finalize the gluing: Once the wheel is assembled in all its components, it is necessary to bring the tire to the maximum of its indicated pressures, (even if it will subsequently be used at lower pressures). This is because it will allow the tire to stick to the wheel in the best possible way. Also helping with the weight of your body, you must lean on the wheel in all its parts, always to make the mastic adhere to the best. At this point, let rest the tubular tyres for 24/48 hours and then it will be ready to be used.
What Factors Affect the Correct Road Bike Tire Pressure?
There’s no one-size-fits-all correct tire pressure for all riders and situations. In general, the narrower a bicycle tire is, the higher the pressure should be. However, pumping the pressure too high can have detrimental effects to performance and comfort, by reducing grip and increasing vibrations. Besides that, the optimal air pressure depends on various factors:
Road surface
On a brand-new super-smooth road surface, a road bike with higher tire pressure will generally roll faster. However on rough roads, that changes. If the tire pressure is too high, the tire can’t absorb the jolts and vibrations from the uneven surface, affecting the bike’s ride quality, your comfort, and how fast you can go. When planning your route, always take into account the surfaces you will be riding on – this will let you adjust the tire pressure accordingly.
Weight
The rider contributes the majority of the overall system weight. That means that you should base your tire pressure on your weight, while also taking the weight of your setup into account. This is especially important in bikepacking, for example, where your extra luggage can increase the total system weight by several pounds. Without tweaking air pressure, the handling, comfort, and puncture resistance of your bike will suffer. Heavy riders should pump more air into their tires than lighter ones. It’s a good idea to inflate the front wheel less than the rear wheel, because the rear wheel carries more weight.
Tire width
Rather than just going ahead and adjusting your tire pressure based on guesswork, it helps to take a look at the sidewall of the tire beforehand. The sidewall displays the standardised ETRTO tire size as well as information on the recommended maximum and minimum tire pressure. Too high a pressure makes riding uncomfortable, whereas too little pressure causes increased wear. Compared to a touring bike with tires between 37-52 mm, road bike tires are narrower and generate less drag. For decades, pro cyclists used tires that were around 20 mm wide. However in recent years, the advantages of extremely narrow tires have been disproven. Nowadays, the trend is going towards wider tires, with the most prevalent widths being 25 or 28 mm. When you accelerate on a road bike, you can really feel the lightness of the tires – their low rotating mass – compared to heavier MTB or touring bike tires.
Tire construction
The material and construction of a road bike tire all have an effect on its optimal pressure. Racing tires have delicate, finely constructed carcasses with a large number of thin cotton or nylon threads. These casings deform more easily at high pressures and have a smoother, faster ride feel. Other types of tires, like winter tires, have stiff, tough carcasses with a smaller number of thick nylon threads. In general, these types of tire need less pressure.
Temperature and weather
In wet conditions you should lower your road bike’s tire pressure by about 7 psi to maintain grip. At high temperatures, your tire pressure increases all by itself – especially if you’re riding carbon rims. To avoid the pressure building up to dangerously high levels, you should drop your pressures on hot days with long descents.
