Custom Wheels & Tires

Vehicle compatibility: Ensure the wheels and tires fit your vehicle model’s wheel well size and suspension without rubbing or requiring modifications (lifts/levelling). 
Wheel offset & fitment: Fitment refers to the specifications that define how a wheel will fit a vehicle. The wheel Offset affects both fitment/function and aesthetics. 
Driving conditions: Select materials and tread patterns suited to the terrain and weather conditions you will be driving in. 
Performance: Consider what activities you will be using your vehicle for, whether it's driving on highways, towing, or off-roading. This will dictate the type of tire and wheel most suited for you.
Aesthetics: Choose a style that matches your aesthetic preference whether it is an aggressive look or stock/clean look. The colour and spoke pattern of the wheel will impact the appearance. 
Cost: Prices vary significantly based on material, size, and quality. 

Summer/Performance Tires: Lightweight with shallow tread for better traction, cornering, and braking in warm weather.

All-Season Tires: Moderate tread depth for dry and wet conditions. Only suitable for spring, summer and fall as they lose traction below 7°C.

All-Weather Tires: Hybrid of all-season and winter tires, flexible above and below 7°C which offers grip on snow and slush. Certified with Three-Peak Mountain Snowflake.

Winter Tires: Stay flexible in cold temperatures with deep grooves for grip on ice and snow. May have a longer tread life since they aren’t driven in dry conditions. Certified with Three-Peak Mountain Snowflake. 

All-Terrain Tires: Versatile for highway and off-road, with reinforced sidewalls and open tread for traction. Can handle most weather conditions including light snow. 

Mud Tires: Unparalleled off-road performance in deep mud, with rigid side walls (added puncture resistance) but shorter tread life and louder noise on highways. Less effective in cold, wet weather. 

It depends. Your original equipment (OE) lug nuts might not fit properly on aftermarket wheels due to differences in seat type, thread pitch, and length. It is best to check with an aftermarket specialist to see if your new wheels will require specific lug nuts. 

33" tires: May fit on some trucks without raising the truck, but a lift or level is often recommended for better clearance and to prevent tire rubbing. 
35" tires: Almost always require a lift or level kit to fit properly on most trucks. 

For best results consult with an aftermarket specialist for specific specifications. Our team at Black Rock would be happy to assist you. 

If your vehicle is new, or has original tires, check the number sequence on the side of the tire. Otherwise you can also check the owner’s manual to find the correct tire size, or check the information on your vehicle’s door jamb. 

Aluminum wheels: Made primarily from aluminum, lightweight, good for performance, and aesthetics, but can be more susceptible to corrosion.
Alloy wheels: Made from a mixture of metals (usually aluminum as the main component) that offer similar benefits to aluminum wheels, but with potential variations in strength depending on the alloy composition. They offer better aesthetics and lighter weight for on-road driving.
Steel wheels: Heavier than aluminum or alloy wheels, but more durable and resistant to damage. They are often used for winter driving or off-road application, but are generally more durable and cost-effective for off-road use.

P-Metric Tires: Designed for passenger vehicles such as sedans, crossovers, SUVs, and light-duty trucks. They offer a smoother ride, are ideal for daily driving, and handle light to moderate loads. Typically 4- or 6-ply. They can manage light to moderate loads.

LT Tires: Designed for heavy-duty trucks, off-roading, towing, and hauling heavy loads. They have reinforced sidewalls for durability but may provide a stiffer ride. Typically 8 - to 12-ply.

A directional spoke is a spoke in a wheel that rotates in a specific direction. Directional wheels are designed for the left and right sides of a vehicle so that all wheels face the same way. This design can make a vehicle appear like it's moving, even when it's stationary.

Offset is the distance between the wheel’s centerline and its mounting surface, affecting how the wheel sits relative to the suspension and body.

• Positive Offset: Moves the wheel inward and keeps it within the wheel well, improving stability but may cause clearance issues.
• Negative Offset: Pushes the wheel outward, widening track width which can help stability for off-road vehicles. It may require fender modifications.

Backspacing measures the distance from the mounting surface to the wheel’s inner edge, determining clearance with suspension components.

• Formula: Backspacing = (Wheel width / 2) + (Offset / 25.4) (measured in inches)
