The Invention of Tyres-
The first rubber tyres appeared in the mid-1800s. They were solid or cushion tyres in which the rubber itself carried the load, absorbed shocks, and resisted cutting. The pneumatic or air-filled tyre, which carried the load and absorbed shocks by the compressed air in the tyre casing, was patented as early as 1845. Solid rubber tyres were preferred over pneumatic tyres because of their durability, so pneumatic tyres were not used much. The popularity of bicycles in the late 1800s revived the idea of the pneumatic tyre, and in 1888 a Scottish veterinary surgeon named John Boyd Dunlop obtained a patent for a pneumatic bicycle tyre who was familiar with making rubber devices, he re-invented the idea for his child’s tricycle and developed them for use in cycle racing.
The first big innovation was the introduction of steel wire as a component. Developed in 1934 by Michelin, already established as a major tyre-maker at the time, the embedded steel wire allowed the bead to firmly attach the tire to the rim, invented in 1904. Firestone took things to the next level in 1923 when they introduced the balloon tyre. It’s a low-pressure tyre that enabled more of the tyre surface area to make contact with the road, thus gripping the road more firmly to improve the handling and performance. Similar tyres are still used today on off-road vehicles and sand buggies.
Radial tyre developed in 1948.This outperformed the bias-ply tyre constructed that preceded it. Although the use of radial tyre technology spread quickly throughout Europe and Asia (it boasted superior handling and fuel economy numbers), it took a while to catch on in the US. It wasn’t until 1966, when the consumer advocacy publication, awarded its two top spots to radial tyres. The magazine cited longer life, increased safety, handling, and noted that the in the long run, the costs of running on radials was far less than bias-ply tyres, which needed to be replaced frequently.
In 1967, Goodyear, the world’s largest tyre company, introduced their response to the radial, a bias-belt product called the Custom Superwide Polyglas The bias-belted tyre simply added a fibreglass belt to the bias-ply tyre. The bias-belted tyre would last 30,000 miles compared to 40,000 for radial and 23,000 for bias-ply tyres. It could be used on cars designed for bias-ply tyres.
The Tubeless Tyre
Unlike pneumatic tyres which use a separate inner tube, tubeless tyres have continuous ribs moulded integrally into the bead of the tyre so that they are forced by the pressure of the air inside the tyre to seal with the flanges of the metal rim of the wheel.
Many patents had been filed covering tubeless tyres. Killen Tire applied for a patent in 1928 and was granted in the UK in 1930. The Wingfoot Corporation, a subsidiary of Goodyear Tyre were granted a patent in South Africa in 1944. Due to technical problems, most of these designs only saw limited production or were abandoned.
Frank Herzegh working for BF Goodrich applied for a patent in 1946 and eventually received a patent in 1952 in the United States. By 1955 tubeless tyres became standard equipment on new car
These tyres consisted of a strong outer tyre that absorbed the shock and damage of the road and an inner tube that held the air. Unfortunately, if the inner tyre developed a leak, the whole tyre would deflate due to the friction between the two. So, Goodrich developed the first tubeless tyre. They reinforced the outer walls, and so eliminated the inner wheel. This change lengthened the tyre lifespan, improved reliability and made the ride more comfortable.
The Run-flat Tyres
Even with scratches or holes caused due to obstacles while driving, and the resulting decrease in air pressure, the run-flat tyre is able to maintain a constant driving speed. It protects the driver from various accidents that can arise in emergency situations.
Today, we have better bikes, better tyres, better tubes, highly advanced technology and we still have flat tyres.Currently, Goodyear holds about 20% of the global market share in radial tyres, both original equipment and replacement; Michelin 19%; Bridgestone, 17%; Continental, 9%; Pirelli, 5%; and the others, 30%.
Tyre Blowouts are extremely rare but getting a puncture or a blowout while driving can be a scary experience – especially if you have never experienced on before or if you’re driving at high speed on the road.
There are many reasons why you might encounter a tyre blowout while driving-
- Driving with under inflation tyre
- Driving over a hard or sharp object/obstacle. Ex: a stone, block, brick, bottle, or metal bevel.
- Overloading the vehicle, leading to an overheated tyre.
- Over-inflation can cause a tyre blowout
- Excessive tyre wear or age.
- Manufacturing defects on the tyre.
Steps to Handle and Avoid Tyre Blowouts-
- Check for Tyre Wear
- Inspect Tread Depth
- Look for Damages on Tyres from Improper Use
- Bulges in Tyres
- Keep a firm grip on the steering wheel.
- Do not slam on the brakes.
- Let your car slow down gradually.
- Pull to the side of the road once you have slowed to a safe speed.
These tips should help you in understanding a tyre blowout and also how to handle these unexpected blowouts. Please look for signs and wear on tyres as this could be life-saving in more than one way.
Tubeless tyres primary cause of punctures is the penetration of a foreign object into the tyre, leading to air loss. But unlike a tube-type tyre, the loss of air in a tubeless tyre is usually gradual. Tubeless tyres tend to have a thicker construction, especially for the sidewalls as they need to withstand stresses and retain air.
Puncture prevention tips
- Always maintain the correct tyre pressure and check the air pressure at least once a week if possible, when the tyre is cold
- Never over-inflate or under inflate your tyres
- Check for rim bending and rust build up and attend to this as soon as possible. Use alloy wheels if you can afford them.
- Carry a tubeless tyre repair kit and/or a portable air compressor in the car
- You could use products like Slime or other sealants in the tyre that will help seal minor leaks
- Ensure the spare tyre, jack and jack handle are easily accessible in the car
Finally if there are too many punchers on the tyre it is best to replace the tyre with a new one to avoid future accidents and most importantly yours and your family’s safety!

Major Indian Tyre Manufacturers are set to take price hikes upto 3%.Tyre marketers said rising price of inputs is the reason why there have been multiple rounds of small price hikes this year. Said Vikram Malhotra, marketing director, JK Tyre : “We will have no choice but to increase prices in all categories. Prices have been continuously rising since the last 5 to 6 months. While natural rubber prices have reduced to Rs120/kg level from peak of close to Rs150/kg, it is the crude price that has had a major impact.
Crude prices have gone higher than $70 per barrel due to OPEC production cut back and geopolitical tensions. Tyre companies are dependent on several crude based derivatives for their raw materials – synthetic rubber, nylon tyre fabric, carbon black and others. Prices of these crude based derivatives are moving upwards. This has directly increased input cost pressure for tyre companies.
The largest tyre manufacturer in India, MRF, has put in a word of caution regarding input price in its Q4FY18 result press release. It stated in the press release that “Escalation in the cost of crude based inputs remains a concern and will add pressure to the bottom-line”. Most of the hikes are in small doses spread over two or three months and there are hikes on specific patterns and tyre categories aswell.
Fortunately, the demand for tyres both in the OE and replacement markets across most segments has been strong, translating into commendable sales growth. That is why some tyre firms are confident of passing on some of the cost pressures through price increases in the coming months.
A car accident will always be unpleasant and also happens to careful drivers. While no driver wants to be involved in a car crash, sadly some accidents are just unavoidable. After a car accident, you might be stunned with shock, dizzy with adrenaline or enraged at the guy who might be responsible. Remember that this is why we have Insurance-to financially protect ourselves and others. The first thing to do is – “Take a deep breath,” this can help you shift your focus from the trauma of what just happened to what you need to do next.
Use the tips below to prepare yourself to handle the stressful aftermath of an accident.
Check on yourself the other people involved-
Check if you have any injury and anyone else if they are seriously injured or needs medical attention. If they do, that must take priority. If they do not, you can proceed to swap information like contact details. Be sure the place you pick to exchange information with the other driver is safe and doesn’t put either of you at risk for another accident.
Check your Surroundings-
Keep in mind there may be other cars still involved in the crash coming to a stop. There is also the risk that other cars coming through the danger zone. If other cars could potentially crash into your vehicle, the safest move for you is usually to stay in the car. If you have checked the surroundings and it’s clear then it would be fine to exit the car.
Document the Crash-
When the police/medical team arrive later, make sure you tell them exactly what happened, to the best of your ability. If you do not know certain facts, make sure you tell that you are not aware. Do not speculate or guess any of the facts. If you are asked if you are injured and you are not sure, say you are not sure, rather than no. Often, the pain and injuries from motor vehicle accidents become apparent hours after the accident.
Take Pictures for Proof-
If you happen to have a camera/smartphone in your vehicle, you should take pictures of the vehicles if there is visible damage. If you have visible injuries, you should photograph them as well. However, you should in no way interfere with the on-going police investigation. If you cannot take pictures at the scene of the accident, take them as soon as possible after the accident.
Seek Medical Attention-
The injuries caused by motor vehicle accidents are not immediately apparent. Most of them report feeling the most pain a day or two following the incident. Unless you are absolutely certain you are not injured, you should seek medical attention at your local emergency room or by seeing your family physician. Even in accidents involving minor impact, you can sustain a serious and permanent injury to your spinal cord. If you lost consciousness or were dazed for even a short period of time following the collision, you may have suffered a concussion or closed head injury.
Contact your Insurance Company-
You may want to call your insurance agent while you’re at the scene. That way, they can tell you exactly what they will need to in order to process your claim and what to expect.An accident can leave even the most experienced driver in shock, but following these steps may help protect you from unnecessary worries. That way, you can work with your insurance company to get your vehicle repaired as smoothly and as quickly as possible.
Surviving an accident can feel like a victory. But don’t let your post-crash shock distract you from taking care of business, both at the accident scene and in dealing with insurance claims.
