Recommended Tire Options
In order to get the most performance out of the other modifications you've done that are required to use these fitments, these setups should only be used with aggressive tire compounds such as the Nitto NT01 or Hoosier R7. Other tire sizes may also work in addition to what’s listed below.
Nitto NT01 (100TW) - The NT01 is one of the highest performing track day tires on the market and is available in all of the most popular sizes. This tire is not recommended for a daily driven car, or even for a car that is driven to and from the track. These tires will wear extremely quickly and are best used for cars that are trailered to and from events.
Hoosier R7 (40TW) - The Hoosier R7 tires are as close as you can legally get to a full-on racing slick. These tires are recommended for race and autocross ONLY. Due to the tread pattern, these tires are not recommended for any street use, even when driving to and from an event. The Hoosier R7 is developed for drivers who compete in road racing or time trials, where responsiveness and high levels of grip in hot & dry conditions are desirable. The R7 is not designed for damp or wet conditions. The R7 is a rewarding tire for the enthusiast looking for the fastest and most consistent lap times. The R7 provides extended wear for this tread-wear rating due to the tire compound being a bit harder than the Autocross-only “A7” variant.
Fitment Type: Dedicated Track/Race
Recommended for: E46 M3. All hardcore track enthusiasts, time trailers and W2W Club Racers. This category prioritizes performance above all-else, and includes both staggered and square configurations to best suit each individual drivers priorities, goals and preferences for their vehicle. Motorsport oriented suspension setups with aggressive negative camber specifications are par for the course here, unless class rules prevent such modifications.

FIT MATTERS
The right solution for every application
The SM-10 wheel includes details specifically implemented to enhance the BMW owners' track day and street performance experience. An optimized car setup begins with the right wheel and tire fitment, and without model-specific attention, maximum performance is compromised. These wheels were developed for various BMW chassis’s and will work in either square or staggered configurations.
FACE PROFILE
One design, many levels of beauty
Two face profiles will be utilized to maximize spoke concavity and reduce weight on the SM-10 design. The medium concavity is offered on narrow-width applications, while the deep concavity is offered on the APEX wide-width applications. Concavity is dependent on fitment, and not selected independently.
“I” BEAM SPOKES
More than just a pretty face
The spokes of the SM-10 were designed to be robust where they need to be, and extra lightweight where they should be. Weight is reduced by CNC machining material out from the sides of each spoke. It’s expensive and avoided by almost every manufacturer, but affordable with volume. In each size of the SM-10 designs, the I-beam spokes are carefully evaluated from structural aspects to ensure minimal weight, brake clearance, and remarkable strength.
BEEFIER LIP
Ready for more abuse
By saving weight elsewhere, APEX has added extra material where it counts. The barrel’s inner lip is beefed up on the SM-10 to better handle the repetitive abuse seen on the track.
OPEN HUB CENTER
Easy to access lugs
Race wheels can't just be light, they need to function in a high performance environment. Unlike the narrow lug recesses of most other wheels, the SM-10 wheel features a wide open hub center that easily accommodates oversized race lugs and beefy impact sockets. This allows for quick and easy wheel changes and prevents chips and scratches from tools.
HUB CENTRIC
No rings or adapters here
All APEX SM-10 wheels are purpose built for select vehicle applications, and centering rings are never required for any BMW application. All 5x120mm bolt pattern wheels feature a direct-fit, 72.56mm center bore.
BRAKE CLEARANCE
A lot of room in a tight space
Spoke clearance is only half the problem. The barrel construction on a wheel also needs to be big enough to clear the sides of your caliper and rotor. Many aftermarket wheels that have aesthetic compromises in their design may work with smaller stock brakes, or smaller diameter big brake kits, but the larger kits will pose a major problem. The barrel of the SM-10 wheel offers unmatched caliper clearance because wheels shouldn’t limit your choice of aftermarket brake kits, and brake kits shouldn’t force you to run oversized wheels.
WHEEL HARDWARE
Original or aftermarket, it all works
The SM-10 wheel can be used with all OEM and aftermarket mounting hardware with a 60° tapered seat. Lug bolts, wheel locks, and stud conversion kits all work perfectly. The SM-10 wheel also accepts wheel spacers without issue. The shallow rear chamfer allows the wheel to remain hub centric even when 5mm flat spacers are used. The chamfer is deep enough to clear the chamfered lip found on some aftermarket spacers that would typically cause improper seating of the wheel and, therefore, wheel vibration.
CENTER CAP
A factory fit and finish
Every APEX wheel is designed to work with factory center caps. You can easily replace APEX center caps with OEM roundels for a clean factory look. APEX wheels will come with the redesigned, Gloss Black center cap that mimics the size and shape of a BMW factory center cap.
TPMS SENSORS
They all fit
TPMS sensors, which monitor tire pressure, are one piece of technology that can't be compromised. The attention to OEM compatibility on the SM-10 wheel doesn't end with center caps. All APEX wheels accept OEM and aftermarket equivalent TPMS sensors, and any standard sized metal or rubber valve stem.
