🏁 MG kart tire pressure guide for Rotax, IAME, LO206 & more in all weather conditions

At Nashville Karting Group, we support local racers with real-world data and tuning tips for success on track. This guide covers the best MG tire pressures for Rotax MAX 125 Evo Senior and Junior engines, as well as LO206 karts. Whether you're racing in summer heat or winter chill, we’ll help you fine-tune your tire pressures for maximum grip and performance.

☀️ Dry Weather – MG Yellow & Red Tire Pressure Recommendations

Key Tip: Always check pressure immediately after a session. The goal is to land around 14–15 psi hot for MG Yellows and 13–14 psi hot for MG Reds. If hot pressures are too high, lower your starting pressure next session.

🌧️ Rain Tire Pressure Guide

When the skies open up, you need a completely different tire strategy. Here's how to adjust for rain racing:

Rain Setup Tips:

• Increase tire pressure to build heat quickly.

• Remove seat struts (if allowed) to increase flex.

• Soften the rear by using a softer axle or loosening seat bolts.

• Widen rear track and narrow front track.

• Remove front torsion bar if adjustable to add front grip.

🔧 How to Adjust Tire Pressure Based on Track Conditions

• Grip fades after a few laps? You started too high. Drop cold pressure by 0.5–1 psi.

• No grip in the first laps? Raise cold pressure for faster warm-up.

• Uneven tire wear or temps? Consider pressure balancing left to right or adjusting camber.

• Hot + humid day in Nashville? Start at the low end. Moist air and radiant heat will raise hot pressures faster than expected.

🛞 Final Thoughts

Tire pressure is one of the most important — and affordable — tuning tools in karting. Whether you're racing a Rotax, IAME, LO206, or even a shifter kart, the right MG tire pressure can give you a serious edge on track. Use these guidelines as a starting point and fine-tune based on your chassis, conditions, and driving style. From blazing hot summer days to cold, grippy winter races — tire pressure matters more than you think.
