Do the airbags make a big difference???????

Yes they do...

But only in stance, not carrying capacity. They don't help the axle bearings.

No. But unless youre towing more than 10-15 times a year long distance, theyll be alright. Gotta worry about tires before anything else

I only tow my 5 th wheel about 6 times a year about 200 miles round trip..I know my f150 can tow it with no problem

I've shown that you will run out of GAWR (rear) before anything else, including tire weight rating. My tires for example are rated 4500 lbs (2250 each). The rear axel is rated at 4000. This is based on gears, bearings, axel and suspension.

I have Pirelli 275 55 20s on by the way. For me, tires are not the limiting factor.

omaraleman2002

That is correct ..

I sort of amazed that you're hauling all that weight with P-rated tires. Not because they aren't rated for it, they are, but don't they squirm quite a bit?

The LT tires should have stiffer sidewalls making for a less comfortable (unloaded) ride but also less "loosey-goosey" handling. No?

Fair question..

With it being a 55 series tire, there is not a lot of sidewall to allow the tire to warble. By inflating to 44 PSI (cold, checked before every heavy haul), I think that also helps stiffen the sidewalls.

Re: less comfortable ride, my *** (the jury) is still out on whether LT, or more inflated tires are less comfy than OEM/less inflated. I have super springs in the rear, it lifted it a bit and I am sure, stiffens the ride, even unloaded. Do I notice being in leather seats, closer to the front coil-over shocks? I don't think I can tell. The F150 ries real nice, even with 44 PSI and the helper in place, I am not sure it changed the ride. As a test, I took dad for a ride once, never said anything, and he told me how nice the truck rides. Not scientific, but good enough for moi!

Once these P rated wear out (and so far there is no unever wear), I'll look for LT/E rated. BUT! Ever see the price of 20" LT/E rated? Damn! you could buy a small car for a price of 4 of these. Damn!

I'v got a set of 17's that I bought cheap, now I just need to get the tires. My plan is to use them on the rears when I'm pulling heavy. It might look a little goofy but at least I will lessen my chance of being on the side of the road with a blowout. I'v seen the prices of 20's they are crazy high.
