"Tire shield" for protecting dual wheels from stone damage?

Good analysis!

I read up on these a bit. Sounds like this is more of an option for fleet operations. The engineering implications, especially for drive wheels, are large. Big changes in geometry.

> Tractor trailers

Two tire techs told me, when duals on dump trucks and road tractors are operated in an environment with large loose stones this problem occurs. When they are not, it doesn't.
