"A three year joint study (3) with Forest Engineering Research Institute of Canada (FERIC) and the Alberta Newsprint Company (ANC) investigated the potential for using a B-Train combination equipped with central tire inflation (CTI). Three road surfaces were studied; native earth block-entry, lightly gravelled forest access roads and asphaltic-concrete highways. The native earth thawing block-entry road was constructed as a 100m X 75m two lane oval track. The track had a low section, a level section and a 6% grade. The outer lane was used for “high” tire inflation pressure and the inner lane was used for “low” tire pressure conditions. The single test vehicle operated on one lane at high tire pressure until the road failed - defined as when ruts of 10 cm in depth occurred. It then travelled on the other lane at the low tire pressure setting until the surface failed. During the test program, the tire inflation pressure settings were as follows; high-pressure condition was set to 100 psi; low pressure ranged from 34 to 39 psi. The test vehicle was a 7-axle unit having a GVW’s of 56.5 tonnes.
The tests found that tires inflated to the high pressure (normal) settings rutted the road surface approximately nine times faster than when inflated to the low pressure settings. This extreme result is due in part to the very weak structural condition of the road. It is estimated that the road had a CBR of 3, which is typical of weak, thawing conditions. In general, initial rut development decreased by 77% when low tire pressures were used."
It depends on how heavy the angel is, and how small the point of the needle is. But yes, potentially an angel standing on a pin will damage a road.
Have you ever ridden a bike with narrow wheels on a freshly paved road? I have. It made a rut.
