Longacre Racing Products Tire Pyrometers: Race-Grade Temperature Analysis

Tire pyrometers are one of the most powerful chassis-tuning tools a racer can carry to the track. By measuring temperature across the inner, center, and outer tread zones of each tire, a pyrometer tells the story of how a car is loading its rubber — revealing misaligned camber, incorrect tire pressure, suspension imbalance, and more. Few brands have invested as deeply in this discipline as Longacre Racing Products, whose pyrometer lineup has become a benchmark for serious competitors at every level of motorsport.

A Lineup Built Around Real Racers' Needs

Longacre's tire pyrometer range spans from straightforward digital memory units to advanced tablet-integrated systems. The Standard Memory Tire Pyrometer is a proven entry point: it shows three temperatures per tire and up to twelve temperatures at once , while a backlit display ensures easy reading in all light conditions, and ten-set memory enables easy tracking of tire temperature trends and comparisons between different sessions or races. It is equipped with a Type K thermocouple probe that is replaceable, ensuring durability and longevity of the tool. The display is factory switchable to read in either °F or °C, providing flexibility based on user preferences or regional standards.

Stepping up, the Deluxe Memory Tire Pyrometer adds even more capability for the data-driven racer. Memory stores 10 complete sets of temps (120 total) with quick and easy recall, special software prevents accidental erasure, and the unit computes tire temp averages for temperatures just taken, recalled from memory, or manually entered previously. The pyrometer comes with a built-in night light with auto shutoff, fast-response coiled cord adjustable tire probe, and carrying case, and also features a built-in four-car stopwatch with 70-lap memory for all 4 cars.

Anticipation Circuitry: Longacre's Key Innovation

What sets Longacre pyrometers apart technically is their proprietary Anticipation Circuitry. The pyrometer has special circuitry that determines the final temp more quickly and accurately than ordinary pyrometers — simply stick the probe into the tire and push the READ button; no need to wait for the reading to stabilize, as the microprocessor does this automatically. This is called "Anticipation Circuitry" because it electronically anticipates and computes the final stabilized temp based on the rate of temperature change of the probe. This system gives more accurate and consistent readings and helps minimize the variations caused by different people's style of taking tire temps.

Tablet-Integrated & Wireless Models

For teams that want to bring their data workflow into the modern era, Longacre also offers tablet-connected pyrometer systems. A new magnetic mounting base allows the user to easily operate the pyrometer as a handheld unit, while the large high-resolution display shows all 12 temps at the same time. These models store up to 99 sets and feature an exclusive Anticipation Mode that uses a precision algorithm to predict the ultimate temperature, making taking all 12 temps even faster and more accurate. A wireless probe version is also available, designed to fit any Android phone or tablet via the universal magnetic mount.

The Right Tool, Properly Equipped

Used to fine-tune vehicle setups, Longacre's pyrometers provide precise data for optimizing tire performance and overall vehicle handling. Whether you are campaigning a kart, a dirt late model, or a road-racing sports car, this level of measurement intelligence can translate directly into faster lap times and longer tire life.
