Century 120 vs Volvo 760

[Mark and Dale Bruss]

 

Only if you have differential locks and they are engaged. The differentials allow just the opposite of what you describe as happening > differential speed of the inner and outer wheel sets.

There is no differential between dual wheels. They are bolted together.

 

A differential allows wheels on the opposite end of an axle to turn different speeds and directions..

Mark, I didn't understand you were speaking of the wheels on the same side if the vehicle. The example you describe is the same for any vehicle though, whether dual wheels or single. There is always tire scrub unless the tire tread is round like a bicycle and hard enough to not deform under load.

A power divider is a differential between two axles and power is going to both axles when both have traction. Locking out the power divider locks both axles together front to back. Using axle diff locks lock the axle shafts and wheels together side to side.

 

Lightly loaded tandem drive axle trucks tend to pivot on the front drive axle and scuff the rear axle in a turn.

Single wheels might scuff sideways in a turn. With duals, one the tire is scuffing in the rotational direction.

 

There are those who beileve that a tandem dual trailer (Newmar) has less tire scrub that a triple axle single. The tandem duals will have 4 tires scrubbing (assuming a pivot in the center of the tandems) wna d the triple axle will hve four scrubbing
