Choosing the Right Tires for Your RV
Selecting appropriate tires is crucial for both safety and performance. This section explains the distinctions between various tire types and how to choose appropriately.
Understanding Tire Ratings
Tires come with specific ratings, indicating their load-bearing capacity and intended use. RV tires are typically denoted with the letters “ST” for Special Trailer tires, designed to handle heavier loads.
On the other hand, passenger vehicle tires (indicated with “P”) lack the sidewall strength necessary for RV applications.
ST vs. Car Tires
Using P tires on RVs can lead to myriad problems, including faster dry rot, increased risk of blowouts, and poor handling. ST tires, designed specifically for trailers, provide stiffer sidewalls that reduce flex and sway while enhancing durability on the road.
Brand Recommendations
Selecting reputable brands can significantly impact safety and durability. Survey data indicates that brands like Goodyear, Michelin, and Sailun have garnered positive feedback for their high-performance ratings and resistance to wear.
