The 2002 GMC Sierra 1500 comes equipped with 245/75R16 tires for both the 1500HD 2wd and 1500HD 4wd models. The recommended tire pressure for both the front and rear tires is 35 psi. The wheels range in size from 16 to 17 inches in diameter and 6.5 to 7 inches in width. The truck has a wheel bolt pattern of 6x139.7mm, a center bore of 78.1mm, a thread size of M12 X1.5, and uses lug nuts as the wheel fasteners. It is advised to have the tires rotated approximately every 7,500 miles to maintain even wear. If you take your vehicle to a mechanic for a tire rotation, you can expect labor costs to range from $30 to $40.
The 2002 GMC Sierra 1500 comes with tires sized at P245/75R16, requires a tire pressure of 35 psi, and has wheels that are 16 inches in size.
You can use P235 tires instead of P245/75R16, but it may impact your odometer reading.
I apologize, but the tires on my 2002 GMC Sierra 2WD are currently sized 235/75/16. Could you recommend another size that would be compatible?
