Just out of curiosity I have the stock 315/70r17s on mine currently and have just been casually been looking at other tires but someone close to me has a set of 305/70r/17s basically brand new and super affordable and was wondering if going to 305s would cause problems or just any general information or thoughts.

 

the tire is about 3/8 inch or 10mm narrower

 

 

As the first to answer your question, YES, it will work, as long as the tire rating is the same or better. This is a heavy pig, so you need to look at load ratings, overall tire diameter, etc.
