Well looks are playing a factor in the decision I can't deny that. I'll be doing a good bit of work to this truck to make it look half way decent, including painting it sometime this year or next. But the functionality and fitment are my main concerns. So It looks like I'll be going with the 38x12.5" TSL/SX then. For it's height they aren't all that wide or at least I don't consider them to be? Another project for this truck in a couple years will be a 460 with around 400-425 horsepower.
My truck is a trail rig, not a hardcore mud machine, and boggers on all 4 corners is the best way to fly with the local terrain. Wide works better here, skinnies always try to find the bottom, but when there isnt one you are toast.
I would go with the lighter ply rating unless you absolutely need the extra weight capacity, the tires will ride and flex much better.
A 460 in the power range you are thinking; which is around where mine is, isn't going to have any issues with those 38's.
Yea I won't trailer anything or put weight in the bed, my concern for more plys was for highway driving as the truck will see around a max of 65mph. I don't know how much plys factor in to higher speeds? I know you need to watch the air pressure and I never had any problems with the bias 36" TSL's on my old F100.
So would you suggest goin with the SX in the front and Boggers in the rear then? I've got a few months to make a decision.
The bogger/swamper combo is a good one. Especially if you do lots of off camber stuff, boggers don't sidehill nearly as well. Nothing like having to dial in over half a turn uphill to go straight across the bottom of my field...
My 44's are 6 ply and I run 9.5 psi, no issues up to 60 mph. Haven't had it faster on these tires as it doesn't see much pavement anymore but I did have it up to 110 on the old 38.5's...
