FAQs

Tires can be segmented on the basis of following categories:

• Cross Ply or Bias Ply
  • The CASING is composed of several CRISS CROSS textile plies, running from bead to bead, at an angle to the rolling direction.
  • The TREAD is not stabilized.
  • The TREAD and SIDEWALLS are formed by the same ply structure.
  • When rolling, the TREAD is subjected to flexing and this causes:
    • Deformation of the tread in foot print area on the ground
    • Friction with the ground
    • Pantographic movement between casing plies like a scissor
  • This Results in:
    • Accelerated wear
    • Less grip due to lower foot print area on the ground
    • Less road holding, as TREAD is not stabilized
    • Increase in fuel consumption
    • Heat buildup, due to pantographic movement (scissoring effect) between casing plies
• Radial Tires
  • The CASING is composed of one single steel ply, running from bead to bead, at 90° to the rolling direction.
  • The Tread is stabilized by a belt made up of several steel plies.
  • The Tread and Side Walls function independently.
  • When rolling, the TREAD is not affected by any flexing and this helps in:
    • Less Deformation of the tread in foot print area on the ground
    • Less Friction with the ground
    • No Pantographic movement as there is only one steel casing ply.
  • This Results in:
    • Increased Tread Life
    • Excellent Road Grip
    • Better road holding & precise driving control due to stabilized tread
    • Increase fuel efficiency
    • Cooler running as there is no pantographic movement (scissoring effect) between casing plies & no tread friction with the ground.

• Summer Tires
  These tires are specially designed to offer optimum performance in summers. They come equipped with a block shaped tread pattern for dry and wet grip. The rubber compound also offers good thermal resistance for improved tire life.
• Winter Tires
  These tires with deep grooves and blocky tread pattern to offer good grip over snow and ice. The pattern is optimized to offer a 'biting-effect' for improved braking over snow. These tires have an innovative compound that keeps the tires warm for better traction.
• All Season Tires
  As the name suggests, these tires offer good year-round performance but they may not perform ably over excessively wet track or at in extreme temperatures.
• All Terrain tires
  These tires are suitable for on-road as well as off-road use. They come equipped with a special tread pattern with large lugs to offer confident over rough and unpaved roads alongside good traction over highways. They also offer long tire life.
• Performance oriented
  These tires are specially designed to offer high performance. They offer superior wet and dry traction along with precise handling and effective braking. Since they are made up of soft rubber compound, the tread life on these tires isn't very high.

• 185 – This part represents the cross sectional width of tire in mm.
• 65 – This part represents the aspect ratio of the profile in mm. 65 would mean that the sidewall height of the tire is 65% of the width of the tire i.e 65% of 185mm.
• R – This part represents the construction type of the tire. ' R ' signifies a Radial construction
• 16 – It represents Rim diameter ( wheel height ) in inches.
• 91 – This part represents the Loading Index of the tire, which is the maximum load bearing capacity of the tire ( in kgs ). 91 means that the tire is capable of bearing a load of up to 615 kgs.
• V – This part is indicative of the Speed Index i.e the maximum speed the tire can achieve without getting damaged. V means a speed rating of maximum 240 km/h.

For best all-round performance, it is not recommended to mix tire brands. This is because every brand would have different construction techniques, would incorporate different technologies and the tires would have different wearing stages. It is recommended to have all tires of same brand and specifications.

For a proper handling and ride comfort, it is recommended to have all tires of same type i.e all tubeless or all of tube type.

Run Flat tires have reinforced sidewalls which help you drive your vehicle for a good number of miles, at a reasonable speed, in case of a puncture.

Optimum air pressure for tires is always suggested by the vehicle manufacturer. It is usually mentioned across the inside of the front doors or B-pillar, as well as on the vehicle manual.

While it is recommended to replace all 4 tires for optimum safety and traction, yet, if you are replacing only 2 tires then it is better to have them installed on the rear axle. This is because over wet or slippery surface, worn-out rear tires could put your vehicle in a ' fish tail ' slide and retrieving control through steering wheel may not be possible.

Tire valves have a rubber base which could get brittle with time. Also, the valve stem may become weak with time. So, it is recommended to replace the tire valves every time you replace a tire. This will prevent any unwanted air leakage.

Keeping an optimum air pressure is one of the easiest and most effective ways of taking proper care of the tires. It offers following benefits:

• Safety
  Under / Over inflated tires are usually one of the most prominent reasons for tire blow-outs. Since they do not offer an optimized contact patch with the tarmac the braking efficiency of the vehicle decreases.
• Tire Life
  Appropriate air pressure ensures a uniform contact patch with the tarmac. This helps in providing optimum performance and leads to uniform wearing, thus, enhancing tire tread life.
• Economy
  Under / Over inflated tires require more power to be brought into motion, and thus consume more fuel.
• Handling
  Tires with correct pressure ensure precise handling and steering response.
• Confident grip
  Tires with correct air pressure offer confident wet and dry grip as they grip the tarmac well.

Nitrogen is an inert gas and its chemical nature keeps it non-reactive. Hence, it does not exhibit any changes in property with change in temperature range. So, a tire inflated with nitrogen is less likely to deflate quickly due to low permeability of the gas. Also, it helps in keeping the tire cool, especially over long highway runs.

Tires usually have a shelf life of about 5 years. With time, they get exposed to variable temperatures and UV-rays. This creates micro-cracks on the tread and sidewall. Such a tire, when used, can cause frequent punctures and blow-outs. So, it is important to use the spare tire as a regular tire with proper tire rotations. If not, then the spare tire, even if unused, must be replaced after 5 years.

While it is recommended to replace all 4 tires for optimum safety and traction, yet, it is okay to replace at least 2 tires. It is better to install new two tires on the rear axle.

Tires usually make noise as a result of uneven or irregular tread wear. This could be caused because of improper wheel balancing or improper wheel alignment. It is best that you get the tires inspected at an authorized CEAT outlet.

Vibration is usually caused because of improperly balanced wheels. It requires an immediate attention. If the vibration persists even after proper balancing, then the fault could pertain to faulty steering or suspension system.

This is a classic symptom that your vehicle requires proper wheel alignment.

While tires may look good, they may not be fit for use if they are older than 5 years from the date of manufacturing.
In case the tires have good tread depth and are not older than 5 years then perhaps they could be used. However, such tires should be used only if they offer confident traction and efficient braking.

While it is recommended to replace all 4 tires for optimum safety and traction, yet, it is ok to replcae at least 2 tires. It is better to installed new two tires on the rear axle.

Any damage to the sidewall is usually irreparable and requires a change of tire. However, it is best to get the tire inspected from an authorized CEAT outlet for confirming the same.

• Vehicle type
• Application / Use
• Tire Rim Combinations
• Speed and driving conditions
• Type of Tread design and Wheel Position
• Load

It is highly recommended that you purchase tire from authorised CEAT dealer.

• Improved traction and cornering grip
• Improved stability
• Improved steering response
• Improved aesthetics

• Increased chances of tire and rim damage by road hazards
• Increased cost of tires and rims
• Insurance Company approval required
• Increased likelihood of contact with wheel arches
