26 inch kenda executioners

So I’m ordering a set of 26x10x12 kenda executioners. I’m thinking of running tens all around. The site says they weight 33 lbs. And have heard on here they tend to run smaller then listed. They are going on my Kodiak 450. No clutch mods just aftermarket air filter and fresh carb clean. I will be installing a pipe and jet kit soon. Will the tires be too much weight on my wheeler? They are going on stock wheels with 45mm spacers. I also have a 2 inch lift to throw in as well. I do ride in some sticky north Dakota clay. Also is there a benefit to running tens on all 4s or should I bump to twelves on the back ?? Can’t decide
