TIRE FITMENT

34" Maximum tire diameter

34x11.50 for no rub on a 9" wide wheel with +12 offset

18" - 295/70R18

20" - 275/65R20

22" - 285/55R22


Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.

Comfortable chair
Color: Black, Color: Black
I wanted an all black out chair to match my cabinets and this chair fits my needs. It was easy to install took me about 20mins or so. Quality is great, the base is made out of metal hence very solid, it came with the polyurethane wheels, rolling on the hardwood floor is very smooth. Seat and arm rest have thick foam paddings makes it very comfortable to seat on and lean back. Adjustable recline tension and height adjustment. Great chair.

GOOD
Color: Black
The chair was more comfortable than I expected for the price. The back support feels good and the seat does not feel hard after working for several hours. I liked that the wheels roll smoothly and the assembly was pretty simple. The design also makes the office look more modern. So far it feels stable and durable.
