Ill call them today, i emailed them yesterday, and someone from carlisle tire replied. And the lady that replied appeared to be incompetent to me. Can only assume they are the same company. EDIT:Well Calling yielded much better results. The technician said that they don't have an exact load specification (that he has anyways, im sure there is one, there is ALWAYs a load specification) but they are built to handle all ATV and UTVs on the market many of which reach 2000lbs GVRW. Again the topic of conversation was ITP Delta Steel rims.
