What does offset mean?
The offset is the distance between the wheel’s centerline and the hub mounting face at the back of the wheel. Typically, offsets are engraved or stamped into your wheel as mm of ET, which stands for insertion depth. At BSA, our expert technicians ensure you always get the correct offset.
Positive Offset: These wheels have their mounting face toward the front face of the wheel. You’ll usually find positive offsets on front-wheel-drive cars.
Negative Offset: These wheels have their mounting face toward the rear of the wheel. You’ll typically find negative offsets on beefy rear-wheel-drive vehicles.
Zero Offset: Zero offset wheels have their mounting face in line with the centerline of the wheel (ET0).
What does PCD mean?
Pitch Circle Diameter (PCD) is the diameter of your wheel’s bolt holes. Your PCD is typically measured in mm and indicates the number of bolts and studs on a wheel. For example, a 4×100 Volkswagen wheel means 4 bolt holes drilled through the center of a 100mm circle.
What does Centre Bore mean?
The Centre Bore of a rim is the size of the center hole in the middle of the rim. Typically valued in mm, the centre bore fits on the hub of a car. To ensure optimal fitting, the wheels need to be an exact match in size to the hub.
Hub Centric: When a wheel is hub centric, it means that the protruding hub on your vehicle and the matching sized centre bore on your wheel are load-bearing. Most modern wheels are hub centric, ensuring that studs and bolts securely hold the wheel onto the hub of the vehicle.
Lug Centric: Lug Centric wheels emphasize the studs and bolts. Ensure you occasionally replace your studs and bolts and tighten wheels ¾ of the way to guarantee they are centered.
What does Plus-Sizing and Up-Stepping mean?
Plus-Sizing/Up-Stepping is the practice of increasing the diameter of a wheel while maintaining the same rolling radius. This will also reduce the profile of your tyres.
Plus-Sizing will improve the responsiveness and handling of your vehicle. It decreases the flexible tyre sidewall proportion to rigid alloy, keeping your tyre tread square and level to the road surface.
However, Plus-Sizing or Up-Stepping can often make your wheels and tyres heavier. This disadvantage is due to tyre inches typically being lighter than wheel inches, which can ultimately decrease your vehicle’s damping deflection under compression and make your brakes look undersized.
How do you install new wheels?
The first step is to ensure you have the right tools and equipment. This includes having the correct bolts for your wheel and the four plastic spigot rings, which are included in the installation kit provided by BSA.
The second step is to jack up your vehicle. Ensure you do this securely by using axle stands and chocking the wheels to stop them from rolling. Stand the wheel up on your car and ensure that all the bolt holes and threads line up. Also, ensure that the wheel fits on the hub properly and that there is enough clearance for the suspension strut, brake caliper, and wheel arch. If you’ve recently upgraded your brakes, it is best to seek professional advice to ensure a proper fit before proceeding with any orders.
The final step is to tighten your wheel bolts according to the manufacturer’s recommended torque. Do so until ¾ tightness, and then lower your car to complete the process fully.
What do I do to care for my new wheels?
BSA offers specialty products designed to care for your new wheels. Our wheel cleaner products are engineered to make cleaning wheels easy. Frequently wash your wheels with mild soapy water and avoid using harsh cleaners, wire wools, electric buffers, and car wash rim cleaners.
To get even more out of your wheels, apply several coats of quality car polish from back to front. This will ensure they last longer and prevent brake dust, dirt keying, and road salt damage. We also recommend treating your rims to protect your wheel paint.
