  why there are more no of tyres at rear of buses and trucks...is it related to roll stability of vehicle

  My general guess is that since the rear tyres have to bear more load than the front ones; they put more tyres. You may put more tyres on the front; but that'd cause make the vehicle less manoeuvrable.
  
  PS: I may be wrong.

  Notice tyre pressure in bikes and trend of remaining pressure while refiling air ☕

  Rear wheel drive(correct me if i am wrong), I think the more surface area give more grip and stability while the time of accelerating with heavier loads.

  To add to big k point
  If types are added at front it increases the width of tyre and it increases the steering difficulty.

  lighter the tyre in front, more easy to handle the vehicle. when we talk about two wheelers. But the reason for having a wider tyre at the rear is that it gives more grip and stability to the vehicle while driving...
  Here I would like to give a good and explanatory example. With commercial vehicles with smaller tyres, its hard to bend the bike while taking a U turn. But in terms of racing bikes, where wider tyres are present at rear, the bend is very easy. This is because more wider tyres, it means more surface are which leads to more contact with the road as a result to more stability.
  But there is a fact about having wider tyres at rear. With the increase in 1 inch tyre at the rear about 3 kmpl mileage is lost by the vehicle...

  You are correct bro but he is asking about number of tyre in rear and why in some vehicles more that two wheels are used in rear alone.

  The reason for more number of tyres at rear is to distribute the load & provide stability while driving uneven long distance.
  A vehicle having 6 wheels (2 front , 4 rear) can work with 4 tyres also (2f, 2r) but, will not get the balance to ride on the road. the two external tyres are used only to provide balance , grip & stability to the vehicle
  
  I'v observed in multiaxle trucks that during the full load condition they use all the tyres but after unloading they lift the pair of middle once. .
