I was just curious, not many people, including myself, keep their original tires. So what is the stock tire size on a 16in. rimon a 2nd gen. ram 1500 4x4 long bed st base model, not the slt or slt laramie, but the st base line model. thanks to anyone who knows

 

I think it could have varied. Some had a 265, others had 245. The off-roads had 275's for example. Check the sticker on the inside of the driver side door frame for what your truck came with.

 

The base ST should have 245/75R16 tires. 265 is an option
