prime tire - 一級方程式賽車 Formula One

prime tyre=首選胎

在F1有四種乾胎可以選擇
Super Soft(超軟胎) -Is the fastest, provides the most grips but has the shortest
life span.

Soft(軟胎) - Is not as fast as Super Soft but still faster than other compounds.
Deteriorates quickly, but slower than the super softs.

Medium(中性胎) - Medium grip, medium wear

Hard(硬胎) - Least grip but last the longest.

The two harder compounds Medium and Hard are called the prime tyre(首選胎)

and the

softer compounds, soft and super softs are the options.
