When to replace your tires
Every tyre has a Tread Wear Indicator (TWI), which form a triangle 
located on the sidewall. TWI is an indicator of tyre wear and is also a benchmark to you to check if your tyre is worn out. Tires should be changed immediately when the tyre tread has surpassed the indicators.

Get the most mileage out of each gallon of gas by following these simple fuel saving tips.
1. Proper Tyre Pressure
When comparing tires that bear the same load, insufficient tyre pressure causes high deflection and increases fuel consumption.
Connection between Tyre Pressure and Fuel Consumption:
| Low Tyre Pressure | Increase Fuel Consumption | Reduce Tyre Life |
|---|---|---|
| 10% | 2% | 15% |
| 20% | 4.5% | 28% |
| 30% | 6.25% | 37% |
2. Optimize Octane
Most drivers mistake premium fuel as the best choice for the vehicle. Check the owner’s manual for the correct octane level for your engine. Around 20% of drivers purchase premium fuel, but only less than 5% of cars on the road have engines designed for high octane fuel. If your engine was not, then pumping premium will only cost you more. (source: American Automobile Association www.aaa.com)
3. Save More by Slowing Down
Gas mileage can be improved by 15% just by decreasing your highway speed from 100 kph to 88 kph. Try to maintain a constant speed and gradually increase or decrease speed when needed to achieve better gas mileage. Slow down on highways and use cruise control whenever possible. Avoid drastic accelerations or sudden braking which uses up more fuel. (source: Consumer Federation of America)
4. Empty Your Trunk of Junk
A vehicle consumes about 700 liters of gasoline each year. Each additional 45 kg of goods increases fuel consumption by 1 liter. Avoid carrying unnecessary items as extra loads put more strain on the vehicle and leads to higher fuel consumption.
5. Use the Recommended Grade of Motor Oil
Follow the vehicle manufacturer’s recommended grade of motor oil to improve gas mileage by 1-2%. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower the gas mileage by 1-2% while using 5W-30 in an engine designed for 5W-20 can lower gas mileage by 1-1.5%. Also, look for “Energy Conserving” on the API performance symbol to make sure it contains friction-reducing additives. (source: www.fueleconomy.org)
Check your fuel cap to make sure it is secure and not damaged. 556 million liters of gas vaporize annually due to missing or problematic caps. (source: Car Care Council www.carcare.org)
6. Drive Sensibly
Smooth and Steady Start Fuel consumption is usually the highest during the initial vehicle startup. Many drivers love to hit the throttle and accelerate to be a step ahead. However, this actually consumes 2-3 times more fuel. From startup to 60 kph, heavy throttle only puts you ahead by 10-20 seconds. 2-3 times the fuel consumption or 10 seconds lead? Make the right choice!
Avoid Braking Abruptly Fuel consumption is usually the highest during the initial vehicle startup. Many drivers love to hit the throttle and accelerate to be a step ahead. However, this actually consumes 2-3 times more fuel. From startup to 60 kph, heavy throttle only puts you ahead by 10-20 seconds. 2-3 times the fuel consumption or 10 seconds lead? Make the right choice!
7. Plan Before You Drive
Before heading out, you should do your homework to find the best route.
Best Route ≠ Shortest Route
Distance is just a factor in deciding the best route. Congestion (too much traffic lights or intersections) should also be considered otherwise the shortest route may turn into the longest route and use up more fuel.
8. Keep Your Vehicle in Shape
Regular maintenance and tune-ups are one of the best ways to improve fuel economy and vehicle performance. Recommended maintenance schedule can be found in the owner’s manual. Dragging brakes, dirty oil filters, worn spark plugs, low transmission fluid, or transmission going into high gear can all reduce fuel efficiency.
9. Proper Wheel Alignment
For every degree the positive camber is off by, the tyre will be dragged sideways 5 m for each km traveled. The driver’s natural reaction is to straighten the driving direction which subjects the tires to additional force and deformation that ultimately increases fuel consumption.
Positive camber is extremely important for wheel alignment!
10. Low Rolling Resistance Tires
Tyre rubber not only has flexibility but also viscidity. When tires are rolling, they will be compressed and stretched which consumes energy. Tyre rolling resistance occurs when the energy loss is converted into heat and increases the tyre temperature.
Choose low rolling resistance tires for better fuel efficiency!
What Is the Appropriate Tyre Pressure for My Car?
The recommended tyre pressure for each vehicle is set by the car manufacturer and can be found in various areas of the vehicle such as: car owner’s manual, driver’s side door,fuel filler door, and etc.
Vehicle load and tyre pressure is interrelated.For larger loads,please increase the tyre pressure.
Please check the tyre pressure when the tyre is cooled to obtain a more accurate measurement. In other words, when the vehicle has been traveling for less than 2 km or parked for at least 3 hours.
Shallow Thread
Bald tires will skid on the road and be damaged by potholes. Groove depth should be at least 1.6 mm otherwise the tires must be replaced.Tread Problems
Tread Wear Indicator (TWI) is a raised section molded into the grooves of a tyre. When the tread is leveled with the TWI, the tires need to be replaced immediately.
Minor Problem:
Check if the tread has been pierced by small stones, glass, metal, or other foreign objects and carefully clean the affected area. If you let these objects get embedded deeper, it may cause serious problems.
Solutions
1. If your car has a spare tyre, please replace the damaged tyre with the spare tyre and take your car to the nearest Giti Professional Service Center.2. Tread puncture diameter 6 mm or below can be repaired. Tread or sidewall puncture diameter greater than 6 mm and tread wear less than 1.6 mm cannot be repaired and are safety hazards.
Visual Tyre Inspection: Are there cuts or penetration on the tyre casing?
Main Reason: tread is pierced by sharp objects or nailsImpact on Tyre: safety hazard
Check Tyre Appearance: Are there bulges on the tyre casing?
Main Reasons:On unpaved roads, tires may bounce over deep holes or be impacted by foreign objects which leads to tyre and rim deformation, causing a break in the sidewall ply. When combined with internal pressure, the break forms a bulge. Additionally, driving up a curb or parking results in the tyre rubbing against objects which cause sidewall bulges.
Impact on Tires:
Safety hazard
Solutions: 1. For your safety, replace tires immediately
2. Tyre bulge or air bubbles cannot be repaired
If tyre casing is damaged, replace tires. Slow Air Leak: Tires will lose a small amount of air pressure every month.
If tires need to be inflated every few days, please check the tires, rims, and valve. If necessary, go to a professional service center to repair or replace tires.
Valve Cap: The valve cap prevents moisture and dust from entering into the tyre. Please use them.
If you replace tires, make sure to fit a new valve cap.
Using damaged tires is extremely dangerous! Suspicious Conditions: Please visit a professional service center for inspection. If tires appear to be damaged, do not use.
Improper Driving Leads to Tyre Damage or Excessive Wear: If vibration or other problems occur when driving and you suspect there is tyre or vehicle damage, please slow down, drive carefully, leave the main road, park, and check the tyre.
Tyre Damage: If you cannot see the tyre damage, please visit a professional service center for inspection.
Tyre pressure, including the spare tyre, should be checked at least once a month or before driving long distance.
The pressure should be checked after the tyre cools down (at least 3 hours after stopping).
Use a tyre pressure gauge to check the tyre pressure.
The recommended tyre pressure for each vehicle is set by the car manufacturer and can be found in various areas of the vehicle such as: car owner’s manual, driver’s side door, and fuel filler door.
Proper tyre pressure helps maintain normal fuel consumption and tyre wear, optimizes tyre life and performance, and effectively improves safety.

Never try to mount your own tires. Visit a Giti Professional Service Center when you need to mount tires.
If you attempt to mount tires, you run the risk of seriously injuring yourself as well as damaging the tires and rims.
Proper tyre rotation on a regular basis will uniformly wear the tyre, extend tyre life, and improve safety.
After traveling for 8,000-10,000 km, we recommend rotating tires at a service center. When rotating tires please keep in mind “4 Consistency” – same brand, size, pattern, and size because some vehicles have different front and rear specifications.
Tires will undergo frequency and speed adjustments at different intervals to keep the tyre and vehicle rotation running straight and the load bearing direction perpendicular to the ground. Vehicle manufacturers designed different angles to handle a variety of road conditions and enhance vehicle performance. Overtime, these angles will suffer wear which leads to deformation while replacing suspension parts will cause a deviation from the set values, resulting in poor vehicle and tyre performance. Therefore, proper wheel alignment can help correct and prevent these problems.
Effects of Improper Wheel Alignment:- • Affects Safety: poor high-speed stability and high-speed cornering ability causes displacement of gravity leading to vehicle skids
- • Increases Component Wear: vibration and shakes leads to vehicle component wear while incorrect angles causes rapid irregular tyre wear
- • Poor Handling: steering is too heavy or too light
- • Driving Fatigue: vibration and shakes will decrease comfort level while constantly correcting the direction of the steering wheel increases driving fatigue
- • Increases Fuel Consumption: unsmooth driving causes large energy loss
- • Steering wheel is not centered when driving straight
- • Vehicle pulls to the left or right when you take hands off of the steering wheel (test on open road)
- • Intense irregular wear
- • Unstable suspension
- • Steering wheel sways from side to side when driving straight
- • Vehicle tends to deviate when driving
- • Vehicle noise or strange sounds develop
- • After replacing suspension component
- • Recommend performing regular wheel alignment checks every 10,000 km
- • After vehicle collision or impact with the road
When tyre and rim assemblies are unbalanced, it will cause wheel shimmy (wheel shakes from side to side) or wheel tramp (wheel hops up and down). Therefore, it is important to achieve static and dynamic balance.
Steps to Balancing:- • Match tyre reference dots with rim marks or valve cap
- • Use professional balancing equipment to balance tires
- • If balancing weight exceeds the limit, reposition the tyre and rim by adjusting 180° or 90 °
- • If balancing weight still exceeds the limit, check if there is a rim deformation
- • Prevents tyre vibration and tyre shimmy
- • Does not affect comfort level
- • Avoid irregular tyre wear
- • Avoid irregular vehicle suspension system wear
Under normal circumstances, tires can meet the vehicle’s designed mileage but a number of factors impact tyre mileage such as: vehicle applications, tyre maintenance, road conditions, weather conditions, driving habits, and etc.
Avoid used tires. You never know what damages the tyre suffered. If you use a damaged tyre, it may cause accidents.
Yes.
Tips That Help Increase Tyre Life:- • Do not speed. High speeds will generate excessive heat, which increases the rate of tyre wear.
- • Avoid fast turns on curves and corners.
- • Avoid quick starts and panic stops.
- • Do not ride on the edge of the pavement or drive over curbs, potholes, or other obstructions.
Main Causes:
Many factors such as the engine, steering system, suspension system, and tyre may cause the vehicle to shake. We recommend you go to a professional service station for inspection.
Impact on Tires:
Causes improper tyre wear and affects tyre life.
Causes:
Poor braking system, positioning, suspension system, transmission, tires, and etc.
Impact on Tires:
Causes improper tyre wear and affects tyre life.
Solution:
Visit a professional service center for inspection.
When freeing a vehicle from sand, mud, snow, gravel, ice, snow, or wet surfaces, excessive wheel spin can result in tyre failure and cause personal injury or vehicle damage.
Do not exceed 55 km/h, as indicated on the speedometer.
Never stand near or behind a vehicle that is attempting to free itself from a ditch because the tires will be spinning at a high speed.
