What are the carrier break points for 10 bolts and 14 bolts? And what are you guy's/ gal's MPG with 4.88's and 5.13's turnin 35's? I believe a 285 75 16 is close to a 35" tire. rjfguitar was laughing at me for not having enough HP for my burb. Since I have a new motor I may as well do the 3/4 conversion and get lower gears to help remedy this situation.
