What ever tires you get make sure there in alignment! i made the mistake of that with a pair of Titans and I made them completly bald in less then 2 months. before i found out they were an inch out.

 

I run like 6 in the front and 5 in the rear to balance the height out on my 27's. Probably should run 4 and 5, but it steers a hair better with more pressure and makes it a little bit taller. For that 25" size, I would run them at 4 probably.

My cousin's husband has a big bear 400 with stockers, and I looked at his front tires the other day and they were major tall and skinny. Took a high pressure guage and checked and he had 27lbs. in both fronts. The rears were normal, and wouldn't even register on the guage. That has to make for one horrible ride.
