What those markings on your tyre mean

[Nikolaiski]

 

The TPC system facilitates tire replacement for GM customers on GM vehicles, meeting the same critical performance specifications of GM vehicle original equipment tires.

 

Tire Size and Construction

 

Tire Type: Identifies vehicle type. P denotes passenger vehicle*;

LT denotes Light Truck.

Tire Width: Measured in millimetres. E.g. 215

Aspect Ratio: The ratio of the height of the tire's cross-section to its width. E.g. 65

Construction: R denotes radial, whereas B indicates a bias construction.

Wheel Diameter: The greatest distance across the wheel from tread to tread, measured in inches. E.g. 15

 

* May also include pickup trucks and SUVs.

 

Load Index and Load Capacity

 

Load Index: The maximum load in pounds (lb.) that the tire can support when properly inflated based on the Load Index Chart. E.g. 89

 

Load Index Pounds Kilograms

75 853 387

76 882 400

102 1874 850

103 1929 875

104 1984 900

105 2039 925

 

Load Capacity: The maximum load in actual pounds (lb.) and kilograms (kg) that the tire can support. E.g. 1300 lbs. or 580 kg

 

Speed Rating

 

Speed Rating: Indicates the maximum service speed for the tire based in the speed-rating chart. E.g. " H " indicates a maximum tolerable speed of 210 km/h (130 mph).

 

Rating Symbol Maximum Speed (km/h)

Uniform Tire Quality Grade (UTQG) Labelling

UTQG stands for Uniform Tire Quality Grading. Developed by the US Department of Transportation (DOT), all tires sold in Canada feature this identification number moulded into the sidewall of the tire.

 

Treadwear

 

Treadwear Grade: A comparative rating (E.g. 220) based on the wear rate of the tire when tested under controlled conditions by the manufacturer on a specified government test track. E.g. a tire with a 200 treadwear rating would wear twice as long as a tire with a 100 rating.

 

More than 100: Better

100: Baseline

Less than 100: Poorer

 

Tread wear grades are only valid when comparing tires from the same manufacturer!

 

 

Traction and Temperature

Traction Grades: : Identify the tire's ability to stop on wet pavement measured under controlled conditions by the manufacturer on specified government test surfaces of asphalt and concrete. The test is based upon "straight ahead" braking tests. E.g. Traction A

 

AA: Very Best

A: Best

B: Intermediate

C: Acceptable

 

Temperature Grades: Denote the tire's resistance to the generation of heat when tested under controlled conditions by the manufacturer on a specified indoor laboratory test wheel. Excessive temperatures can lead to tire failure. E.g. Temperature A

 

A: Best

B: Intermediate

C: Acceptable

 

Tire Identification Number

All tires sold in Canada feature a Tire Identification Number, which provides retailers with information about when and where the tire was produced.

 

Example:

 

B3 : Indicates the manufacturer and plant code

CD : Tire size code

E52X : Optional

2602 : Week and year of manufacture (in this example the 26th week of 2002)

 

The maple leaf symbol indicates this is a Canadian made tire and certifies that it meets all of Transport Canada's requirements.

 

All Season and Winter Tire Markings

 

M+S (Mud + Snow): Indicates this is an all-season tire. Every all-season tire must carry this symbol. For more on all-season tires, click here .

Four Seasons Ico Indicates this is an all-season tire. Sometimes used in conjunction with or instead of the M+S symbol. For more on all-season tires, click here .

Winter Symbol: Indicates that this tire has been specifically designed for severe winter conditions. For more on winter tires, click here .

 

When you buy new tires, fill in and return your tire registration form. In the event of a recall, the manufacturer will contact you. In many cases, you can register online.

sorry as I am new and I cannot post new topic. I have a question. I want to transfer the car but the buyer do not want to re-loan, they will take over the giro and thought of doing private agreement. How do I legalized it?

never do that. For whatever happens, you are still the owner. So you may still face all the shits even though you have black and white. For eg, Bank go after the owner only (that's you). It will be your own problem to go after the so-called buyer that take over your car. You engage lawyer against that fella will also take time. Worst still, if he MIA, good luck to you..

just my 2cents.

not worth takin the rixk braderrr

I was told that we should avoid tyres with manufacturer date of more than 2 years old. Is this true ?

[Sky61]

old tyres will be harden over time,even if the thread is still unused. when the compound is harden,the grip capabilities are compromised..go for fresh tyres

I wouldn't get tyres that are older than a year. Most tyre shop would not take in any stock of >1 year as well.

Hello Nikolaiski,

You have made it very clear. I recently bought a car (Maruti Swift).

I was looking for some stuff like this. Thanks.
