Sure, buses have fewer wheels per passenger but they are also heavier so go through their tyres much faster.
Per Passenger? A bus weighs like 40,000 pounds at most going by a quick google. The average car in the US weighs about 4,000lbs and the occupancy rate of cars is about 1,5, so 2,666lbs / passenger on a given trip. Every bus that has an average passenger rate of 15 and up beats that.
15 passengers on average seems way higher than most buses I've been on. Maybe during the very busiest times, but buses run all day. The many hours they spend with just four or five people aboard will really tank the average.
Buses also have more tires than cars – usually at least 6, but sometimes 10 or more. I still doubt they're emitting more microplastics than cars per trip but the math isn't so simple.

I don't wanna say there isn't busses that might producre more microplastic but an average of 15 passengers per bus isn't like some insane goal to achieve, even in the current world, especially once you factor in that there's also times that there's way more than 15 people on one for a given trip
