I ended up going with the Wrangler Silent Armors this afternoon. Now I got nothing like the $572 deal - that's an awesome price. Mine will be about $820 after the rebate.
I found the lowest price at the local Ford dealership (of all places).
I also got mine from the Ford dealer. I got P265/70R17. Really thought about the LT's, but decided to go with the P's. So far I'm pretty happy with them. Gonna put the camper away for winter soon here, so I'll get to try them out towing then.
Max pressure is 44psi, but they only inflated them up to around 30. I think I'll run them a little higher when I tow, but will probably run them at 30 the rest of the time. They don't bulge much at all when I'm empty at 30psi.
30 is way too low. You are losing 25% or more of the weight carrying ability at that pressure. You should be closer to 38 non-towing and near max when towing.
Kingfish51, do you see that 38 in a manual somewhere, or are you just basing that off the max pressure of 44? I looked on Goodyear's site, but couldn't find any sort of manual. Why would they inflate them so low at the dealership?
I double checked and I misstated earlier - the dealer inflated it to 35 psi, not 30. So it's closer to the 38 you mentioned. I would be interested in seeing any reference you might have though. Thanks

Mostly from experience and looking at things like what the manufacturer recommends for different tires with different load ratings. As vehicle weights have gone up, the recommended pressures for the same LR have gone up. An example would be the 2001, 2004, and 2009 trucks I have had. All came with LR C tires with about the same weight capacity. The recommended for the 01 was 38, for the 04 it was 40, and now for the 09, it is 45. My 07 came with P series with a max of 35, recommended was 35 as the p series was right at the limit. You are closer to the limit with your P series than you would be with a LR C, so your pressures need to be closer to the max.
It is always better to run a little high, than run low, as too low a pressure will cause the tire to have excessive tread wear and build heat at highway speeds, which can cause blowouts and tread separation. Too high in general will only cause higher trade wear as long as pressures are within the tires limits.
I put 275 65 18's on in september. have around 5 thousand miles on them and they are great tires. I got the P rating due to the fact I have never had a blow out on any tires I have ever had and I don't tow a heavy trailer. Ive used these tires all over in all conditions (snow, ice, mud, clay, gravel, dry/wet pavement) and they are awesome. Actually, they seem better then the bfg a/t's.
I too was wondering about going P or Lt but went P. The price was somewhat a factor as my bill was 1126 OTD all included for 3 tires (got one free).
I've been running my 255/75/R17's (Silent Armor Wranglers) at 39 psi with good results on pavement. I left the pressure there when I drove about 30 miles through mountain snow from 1" to 4" deep and they were impressive, especially considering they are not a dedicated snow tire. The relatively narrow width allowed them to cut through the sloppy stuff while retaining good directional control and the tread pattern provided excellent traction even in the sloppiest transition zone (of course they have full tread still).
I also did about 30 miles of dirt road which was mostly slick, wet clay and they gripped really well. When I purposefully broke them free on some of the more slippery sections they hooked up faster than expected.
All in all, I'm suitably impressed. I still can't believe they were less than $600 installed. Normally I don't buy cheap tires.

Those silent armours do have the snow flake rating applied to them.
I've had my set since fall 06, love em. My only bitch is they don't come in 305/70/17, would of like to try that size next. If I can make a suggestion, get the LT IN 285/70/17 IF YOU HAVE 4X4. I think it's a good size, and makes the speedo dead nuts accurate too with gps as reference. They are great tires for the all season driver, never really off roaded with them, sure they do fine too.

That's true but when I said they were not a "dedicated" snow tire I was speaking to their rubber compound. A dedicated snow tire needs to be removed as the weather warms or they will wear out pronto. But dedicated winter tires are the only way to go if you want the best possible winter traction (and the difference is huge, especially in icy conditions). Modern winter rubber compounds have almost made studs obsolete.
