6 axle with 60" spread on tractor

Hello all,

Does anyone has a 60" spread in the drive axle of the tractor and 55" inch on the tridem of the trailer. Just wondering what's the max one can haul with that spread. I've hauled CAT 980's on a tridem RGN with the tractor drive axle spread at 55" and 55" on the trailer but it really makes the drive axle heavy. Was wondering if a use a tractor with 60" spread at the drive axle tandems what diff would it make on the weight.

Thank you,

 

Thanks for the quick response. I'm mainly concerned about IA,IL,IN,MI,MD,PA,NY. Thanks again it's people like yourself that makes this site a goldmine of good and credible info.

 

Almost 36k on drives with a 244" wheelbase 379 and tridem 55" spread trailking. I'll have to dig out the scale tickets to get numbers. Thank you sir

 

what's the max you have permitted?
