1999-2006 1500 2WD and 4WDIn 1999 GM redesigned their 1/2 trucks. Now both 2WD and 4WD trucks use the same 6/5.5 bolt pattern. All '99 to '04 trucks must use 16" or larger wheels. GM introduced rack and pinion steering on the 2WD trucks which require a hub centric wheel. Hub centric means that the center of the wheel must be the same size as the hub on the truck. In other words the wheel on the 2WD models centers on the hub instead of the lugs as past trucks had. This means that only 6 lug wheels made specifically for the GM hub will work properly on the 1999-Up 2WD 1500. Although large bore 6 lug wheels will fit on the truck, a bad vibration is experienced at higher speeds. Most wheel manufacturers have built wheels with the proper 78.3 mm hub bore. 4WD models can use both large bore (108 mm) or hub centric (78.3 mm) wheels. Tahoe and Suburban have the same characteristics as the 1500 beginning with 2000 year models. Beginning in 2005 17" wheels are required to compensate for bigger brakes. Below is a chart with recommendations for tire fitments based on wheel size.

No modification necessary for 285/75R16 unless the wheel has less than 4.5" BS. Sizes larger than 285/75R16 require a lift kit. ***16" wheels do not fit on 2005 and newer models.*** 16x10 Wheels 305/70R16, 315/75R16, 325/70R16, 365/65R16 All sizes on 16x10 wheels require lift kit. ***16" wheels do not fit on 2005 and newer models.*** 17x8 Wheels 265/70R17, 285/60R17, 285/70R17, 295/70R17,
