Re: 13.50's or 15.50's?
Hey Densonfrnc, did you regear? And what back spacing do you have? Your H2 is sweet!!

In fact, at 70mph on a hill, I can easily still accelerate up to 75mph or greater. Prior to the gears, my truck would downshift, and I'm afraid going with 40's would cause this again, even with the 4.88's.
Another benefit I've found by staying with 38's is that no programmers, custom tunes maybe, go up to 40" tire sizes. They top out at 38's. With the gears and programmer, my speedo is corrected. I feel it keeps the truck more drivable. But, please keep in mind, I'm saying this without having driven an H2 with 40's.
I will say, however, that all the pictures with 40" tires is really tempting me. They DO look awesome! Maybe after I get a third car...

Yeah, you can tell you live in FL....lol.
On both of my H2?s, I ran 38?s with 4.56 gears AND a supercharger. The gutless POS wouldn?t maintain 70 mph with the cruise control on without kicking in and out of overdrive.... thus, the reason why I pitched that piece of crap 6.0
At the slightest incline, it would drop a gear down if the cruise control was on.

Re: 13.50's or 15.50's?
Haha. How can you tell I live in FL?
And I'm still debating 40's. I talked to my shop, and they can have someone at Superchips send me a custom tune for my programmer that would handle 40's, thus keeping my speedo correct, and hopefully my powerband. We'll see.

Cause if you're using cruise control and having no power issues, you've got to be on flat pavement....
Speaking of Florida, we left my mom's house at 1pm today to come back to NC. It's now 11:48 pm and we JUST got on I-26.
Holy crap, traffic was a cluster fudge.

Re: 13.50's or 15.50's?
Ohhh, I don't actually use cruise control. I meant I can maintain that speed, but I figured you were referring to flat roads.
And, yes, traffic can suck sometimes.
