Cars No Shadows under wheels

[Little Senna]

Does anyone know how to fix the issue with no shadows appearing under the tyres? this only happens with a select few cars.
I'm running csp 1.76 and sol 2.1.3

It may have been made using 3dsimed, which disables objects casting shadows arbitrarily, and should just be avoided when making cars for AC.

go to KS editor and make sure the tires casting shadows are set to "true"
