On the boggers life expectancy about 15,000 mi. I run 38.5x11x16.5. Awesome tire in mountains on two track roads. Their is no better tire out their, but the bogger likes to side hill and be careful. When you start to side hill throttle is your only friend. The swamper doesn't sidehill nearly as bad. On the boggers one problem I've had is blowing lugs off on the highway on hot summer days. The tire compound is soft and gets softer on really hot days. This has happened on 4 different tires. I was running a little above speed limit when this happend. My 4wd will run 130 mph on 40" hawgs. On the 44" tires on highway expensive. To build a truck on 44's you build to your tire. Steering gearbox and drive lines and yoke upgrades. those tires are great but reliability of componets is questionable. You have to build everything up to last. When a 44"bogger hooks up something has to give. Question is where is you weak link. Things just break sometimes. I run 40" hawgs and they weigh 137lbs on alloy rims each. Thats 548lbs of tire your truck has to get moving. A 38.5x11x16" bogger on alloy rim 8" is around 75 lbs. 300lbs of tire on truck to get moving. This is not counting other related moving componets. So u-joints and drive line componets have to be upgraded. Something to think about and serious financial problems especially in steering componets. Tie rods and frame upgrades and balljoints issues will be addressed with 44" tires. I like the big tires but they have their issues. frame issues on the gearbox area and steering geometry are gonna have to be addressed with 44". Its only money and hope you have a little to back up a 44" tire. My 40" hawg are about 16" wide and a 44" bogger is around 18.5",thats a lot of tire on the ground hookin up. Also hope you have some good friends that know something about big trucks to help you out. I had help on certain issues in steering situations and what is reliable. hydralic assist is the way to go. Offroad design is a good place to start with chevy truck stuff.
