Bus routes can be short or long, while they still need to get the passengers to their end destination in a safe manner. They also have to do so regardless of weather conditions, so regardless if the roads are dry, wet or even filled with snow the buses should be able to safely and remain on schedule. The buses depending on if they drive in cities or more regional driving will have some different requirements. The city buses will have more frequent stops, be impacted by curbs and potholes to a higher degree than the regional buses that tend to frequent more motorways and rely on more long haul driving with wear resistance being key instead of impact durability.
Key with bus tires is that they can withstand the high load, have good low rolling resistance, so that you have low wear and good fuel efficiency. Low fuel consumption is good for the environment, as you will have low CO2 emissions. So make sure that you equip your bus fleet with tires that have long trouble free service life, with minimum unscheduled downtime that will impact the bus passengers and add costs to the operations. Check the tire condition so that the tires are free from cuts and cracks, then make sure that the tread depth is good so that you have good safety properties.
