I bought my 2500 with the 4. 10 axle ratio because I new I'd want to switch to a larger tire size. After months of reseach I think I found the perfect tires for my application: 295/70R-17 Nitto Grappler all terrains. They are noticeably larger than the BF Goodrich 285's and the tread is quieter. They have a load rating of 3415# @ 65psi so they give me 440# more capacity per axle and a better ride. After having the computer reset for 624 rev's per mile, the speedo is dead accurate and I picked up almost 2 mpg on the highway with the lower engine rpm.
They look great on the truck and don't rub like 315's. If someone can help me figure it out, I'll download some pic's of them on my truck.
