im running 39.5 tsl's on the street...well, it's my DD and offroad toy too. im running onetons(which you will HAVE TOO) and im running 4.56 gears, i get MPG in the double digits and it's very reliable. i can take it up to 70-75MPH...but i can hear the tread wearing down and costing me money...haha....isht is expensive no matter how you look at it. i just picked up some 40MTR's to swap on for DD duties, about 80percent of the time...but i do plan on going 44boggers when these 40tsls are done. im also reagearing to 5.13(atleast) possibly 5.38. oh yeah, i've got a TH400 also....3speed, so 5.38 will prolly kill me as far as DD will go.....we'll see though. good luck man. jumping from 32's to 44's is quite the jump.
oh yeah, once my tires get the flat spot out..they ride like butter...that's with 16oz of airsoft pellents in each. now if i could get my damn aligment right...haha
