What hot tire pressure should you run on the track?
Short answer for our BMW M2: most Extreme Performance Summer and Streetable Track & Competition tires preferred a hot pressure of 34-36 psi, with R-compounds and Hoosier Racetrack & Autocross tires happier at 30-32 psi, and one notable outlier (the Falken Azenis RT615K+) thriving at 40 psi. Full results, methodology, and a tire-by-tire table are below.
The Quick Takeaways
- The 32 psi hot pressure we've traditionally used on the M2 sat a touch low for most tires in this group.
- Above 36 psi: nearly every tire got slower and produced oversteer that demanded constant correction.
- Below 30 psi: tires got sloppy, transitions between understeer and oversteer turned edgy, and the grippier sets started rolling onto the sidewall.
- Sweet spot for most tires: 34-36 psi hot.
- Notable outliers: Hoosiers preferred the low end (30-32 psi); the Falken Azenis RT615K+ wanted significantly more (40 psi).
- Outside the extremes, lateral grip differences across the pressure sweep were small - feel, balance, and even temperature distribution mattered more.
Skid Pad Performance and Competition Tire Test
Anyone who's prepped a vehicle for the track knows there are a massive variety of variables to keep track of. Maybe it's because we're tire people (that's absolutely the reason), but one of the most common questions we get from our enthusiast customers is about tire pressure. What's the right pressure to use when you're prepping for the track?
The honest short answer is... well, there is no single answer. There's a lot of discussion - online, in person, behind the scenes - but once you account for tire, vehicle, wheel width, camber, suspension setup, track surface, driving style, and many other factors, it gets complicated fast. Even with all of that dialed in, it's still a balancing act between traction, tire wear, and plain old subjective feel. It's tempting to throw our collective hands up and say "well, it depends." It does - but that's not good enough.
So we used the controlled environment of the test car and skid pad to gather concrete, usable data. This test ultimately serves a dual purpose: we wanted to provide general insight into how pressure affects tire behavior, and - more relevantly - to determine the optimal hot pressures for each tire ahead of our upcoming full track test.
We divided the tires into four groups, the same groups we'll use for the full track test.
The Performance Tire Groups
Super 200 - Extreme Performance Summer (275/35R19)
Endurance 200 - Extreme Performance Summer (275/35R18)
Streetable Track & Competition (275/35R18)
Racetrack & Autocross Only (275/35R18)
The Method, Man
We isolated pressure as the single variable, building tire temperature gradually with laps around our test track and increasing intensity until the tires reached their ultimate hot operating temperature. We then bled pressure down to the initial test value of 42 psi. We recorded one lap in each direction of the skid pad at every pressure level, dropping 2 psi at a time until we swept the full range from 42 psi down to 26 psi. Tire temperatures stayed under continuous monitoring to prevent any uncontrolled influence from heat.
Here are the numbers we landed on - and then we'll dig into what they mean.

What we learned from the pressure sweep
Several things made themselves clear as we worked through the specs. The 32 psi hot pressure we'd traditionally used on the M2 sat a little low for most tires. Incremental differences in lateral traction across the pressure range ended up very slight, but the high and low ends produced more notable results.
At 40-42 psi, nearly every tire was slightly slower and produced excessive oversteer that demanded constant correction. Above 36 psi was generally too much for every tire, while nothing excelled below 30 psi. In the sub-30 psi range, most tires went sloppy - frequent correction was required to manage sudden, edgy transitions between understeer and oversteer. At those low pressures, the tire deformed enough that we ended up driving on the shoulder (and even the sidewall on some of the grippier tires), producing audible scrubbing and visible shoulder wear.
The optimum pressure range for most of the tires landed in the 34-36 psi window, with a few interesting outliers. The Hoosiers generally favored lower pressures, and the Falken Azenis RT615K+ thrived with greater-than-average pressure. For most tires in that 34-36 psi window, they delivered their best controllability - allowing precise placement near the cones with minimal inputs and a stable attitude throughout the lap.
Between the extremes, the variation was more about subjective behavior than measurable grip. We ultimately selected final pressures on the basis of balance, precision, controllability, and even temperature distribution across the tire face - after confirming that lateral traction remained competitive.
