If you’re in the market for a reliable, universal TPMS (Tire Pressure Monitoring System) sensor, Launch-X431 offers two popular options: the LTR-03 Sensor and the LTR-05 RF Sensor. In this technical breakdown, we’ll compare their features, specifications, and ideal use cases.
Quick Overview
Both sensors are dual-frequency (315MHz & 433MHz), programmable, and designed as direct OEM replacements. However, the LTR-05 is the newer, more compact and lightweight version of the two.

Key Differences Explained
- Size & Weight
The LTR-05 is clearly the winner for compactness and lightweight design. At less than 24g and with a smaller form factor, it’s less obtrusive and may be preferable for certain alloy wheels or for users prioritizing minimal weight.
- Installation Angle
The LTR-03 has a noted advantage with its 30° adjustable installation angle, allowing for better alignment on specific wheel hubs.
- Battery
The LTR-05 has a marginally larger battery (350mAh vs 345mAh), though both claim the same 4-5 year lifespan.
- Design Philosophy
The LTR-03 is a robust, feature-proven workhorse. The LTR-05 represents an evolution focused on miniaturization and modern industrial design.
- Compatibility
Both are compatible with Launch i-TPMS TSGUN, CRT5011E and Creader TPMS 5011 V2.
Which One Should You Choose? Our Recommendation
Choose the LAUNCH TSENSOR-03 if:
>> You value the flexibility of an adjustable installation angle.
Choose the LAUNCH TSENSOR-05 if:
- Compact size and lighter weight are your top priorities.
- You want the newest design iteration from LAUNCH’s TPMS line.
- You are working with wheels where a smaller sensor profile is beneficial.
Summary:
For a universal TPMS sensor, both are excellent choices, covering 98% of vehicles. The main difference is size: the LTR-05 is the smaller, lighter option, while the LTR-03 offers adjustable installation.
For most users seeking a direct OEM replacement, the Launch LTR-05 is the recommended choice due to its modern, compact design without sacrificing battery life or performance. The LTR-03 remains ideal for installations requiring specific angle adjustments.
