GMC Sierra 1500 GMT800 2006 4.3i

Generation: GMT800
Engine: V6, Petrol
Power: 200 hp (203 PS, 149 kW)

What wheels sizes are recommended by the manufacturer

The GMC Sierra 1500 GMT800 2006 4.3i is fitted with 6.5Jx16 ET25 rims with tires 235/75 R16 106S as standard. Where is:

• 6.5J — rim width in inches;
• 16" — fitting rubber diameter in inches;
• ET25 — offset of the disk in millimeters.

Vehicle tyre markings 235/75 R16 are deciphered as follows:

• 235 — PROFILE width (cross section of the tyre) in millimetres;
• 75 — profile height in percentage of its width;
• R — radial winding of the cord;
• 16 — tyre diameter in inches..

In addition, information about its carrying capacity and speed parameters — load index and speed index — can be applied to rubber. The load index is a two or three-digit number, the speed index is indicated by Latin letters, e.g. 106S:

• 106 — the maximum allowable amount of weight the tire can carry 950 kg;
• S — the maximum allowable vehicle speed of 180 km/h.

Using the recommended tire sizes will help to avoid problems with driving management, safety and other difficulties. What non-standard sizes can be fitted? Please refer to the table above for possible alternative sizes for tuning. Although there may be other options that we have not described in the table. For example, discs that are wider than the same diameter. Or fit wheels of the same width, but of a larger diameter, which is quite popular among car owners. The choice of disks is huge, you can find copies with the same parameters, but with a offset size of 1-2 millimeters more or less. It is not possible to list all the options.

In this case, the bolt pattern is the same for all types of wheels — 6x139.7. Thus, all discs are mounted on six bolts and the distance between them is exactly one hundred thirty nine point and 70 hundredths millimeters. Car hub diameter 78.1 mm.

Typical tyre pressure — 35 PSI (2.4 bar).

Expert advices

When choosing rubber for a car, you must first be guided by the manufacturer's instructions. Ask yourself a few questions.

• On which roads will the car be mainly used?
• Do you need increased cross-country ability?
• Which part of the road will be the city roads and which highway?
• Will the vehicle carry heavy loads?

Answers to these and similar questions will help determine which tire parameters need special attention.

How to choose the correct car wheels for GMC Sierra 1500 2006?

3 types of wheel rims:

• Stamped (economical price category) — made from a sheet of iron by stamping on the press.
• Alloy — made by "casting" (more reliable than stamped).
• Forged (best quality and more expensive than the previous ones) — are made of light alloys by means of stamping at high temperatures.

The choice depends on financial possibilities. However, it should be borne in mind that the quality of the road surface on which one has to drive every day also has to be taken into account.

Thus, in case of hitting a road pit, the stamped disc will bend and will not harm the tire, and forged or cast tire can break it. There is a possibility that the molded disc may burst or crack.

It should also be noted that repairing "stamping" is cheaper than repairing cast or forged discs. But wheels with high-quality alloy and forged wheels less kill the suspension, because it is lighter and has a more perfect geometry (better balanced).

The same wheels can be rubbed with tires or not rubbed on the same car — the “wheel alignment” adjustment will help here.

What is the tyre pressure?

It is the driver's responsibility to constantly monitor tyre pressure. This will avoid standard problems associated with the operation of the vehicle. Non-nominal pressure values often cause:

• driving impairments;
• uneven tread wear.

Often the car owner independently reduces the pressure in the wheels of his own vehicle. This reduces the load on the suspension, the car is an order of magnitude easier to "pass" the various road irregularities. But it should be noted that a decrease in pressure even by 0.1 PSI leads to serious problems. The main ones include:

• higher fuel consumption;
• fast wear of extreme tread segments;
• less maneuverable.

Equally problematic is the pumped wheel. The central part of the balloon starts to stack quickly. In addition, if the ambient temperature is more than 140 °F (60 degrees Celsius), the tire can simply explode. Which will lead to an exit in the oncoming lane.
