Build Categories

Pick the direction you want to take this truck. Each section has wheel styles, colors, and specs that work for that build.

Daily+

Better than stock, daily-able, OEM+ aesthetic

For owners who want their truck to look noticeably upgraded without sacrificing ride quality, gas mileage, or daily usability. Stock-height suspension with cleaner aftermarket wheels and slightly more aggressive tires. The most common build in Texas because most owners drive their truck every day.

  • Wheel sizing: 18-20" diameter, +18 to +44 offset
  • Tire pairing: 33" effective (e.g. 285/65R18 or 285/55R20)
  • Suspension: Stock height OR mild leveling spacer

Wheel styles that work

Clean 5 to 7-spoke designs that mimic OEM aesthetic but with sharper edges and modern finishes. Avoid super-aggressive concave or beadlock-style wheels - they look out of place on a stock-height truck.

Color recommendations by truck color

  • Black truck: Bronze, machined, black, or red accent wheels
  • White truck: Anything works - gloss black, gunmetal, bronze, machined, chrome
  • Red truck: Black, grey, or machined finishes
  • Grey or Silver truck: Anything - most flexible truck color for wheel pairing
  • Blue truck: Machined, black, or grey - neutral wheels let the blue stand out
