Glossary
Service description
The part of the sidewall marking that states load index, speed symbol, and sometimes single or dual designation — separate from the size string.
Read the complete service description, not just the size. Two tires of the same size can have different service descriptions and different rated capacities.
Real-World Use
A buyer comparing two 295/75R22.5 tires from different suppliers checks the full service description and finds different load ranges, meaning different capacity tables apply.
What to Pair It With
Read this term with the full tire sidewall, vehicle rating information, manufacturer documentation, and the actual condition of the tire.
