Question on tire contact patches shown in photos (1, 2 5, etc.), it does not seem that the tire edges are in contact with the ground. Only about 1/2 of the outside lugs (inside) touch. This may be from the 8" rim width and I would expect the 65% tires to be better than the 60% (which I am considering). So the question is: Is this normal (not knowing inflation pressure and truck appears unloaded)?
Just a question for you tire experts... The wet pavement provided a good contact read.
Thanks and happy new year...

SuperBlue... what Milwaukee said.
Milwaukee... no problem.
gimp419... will do.
1wheel... well the tires all have 50psi in them right now... I looked at them again and the fronts have under a 1/4" of tread(from the outside lugs) that's not hitting the ground, and the rears have around a 1/2" of tread(from the outside lugs) not hitting the ground... now I loaded around 2000lbs. in the bed a couple days ago and did notice the rears had a little more tread hitting the ground.

Perhaps you won't get the treadlife out of the tires that you would on a wider rim, BUT to me, I'd sacrifice the treadlife to have some kick-ace tires like that.
Probably going to think about it for a few more weeks but I really see myself buying a set of those pro-comps unless i find another tire with better fittament to the stock rims.

Hey Jank,
How about an update... How are you liking the tires still?
How many miles do you have on them now? Still happy with the handling etc?
You're my test monkey.. If you continue to be pleased with them I'm going to get a set.

I've heared horror stories about the pro-comp tires... welts splitting off road... Maybe I just want to believe them because I had a couple pro-comp suspension component problems... busting that is. I can never reccommend pro comp for anything more than cosmetics.

Milwaukee... I'm still loving the tires. 
I've got just over 5000 miles on them with no issues with them what so ever. I still can't believe how much better they are in the rain, the stock Conti's would spin big time when blurping the throttle, but these bad boys stick like there's no tomorrow, and because of rain I haven't been able to really test them out in the snow. My one regret is that I didn't put them on my tryck sooner.

Sweet.
As soon as I'm done getting my gauges installed I think I'll pick up a set. I did my tranny temp gauge yesterday and I'll hopefully finish the pyro next week.
I want to see what effect the larger tire has on tranny temps etc.

stebab... me and the truck are still loving the tires 
I've done some light mudding with them and they freakin' ROCK! They do self clean and seem to grip a lot better that my buddies F-150 with BFGoodrich AT's. As for PSI's, I've found that 45psi up front and between 35-40psi in the rear seems to give the best ride quality and performace for light towing/hauling and riding around empty... and for the heavy stuff I pump the rears up to 50psi and she rides perfect.
And for the people who deal with snow covered roads... let me say they are 10 fold better tham the stock Conti's. I can actually drive around in 2 wheel drive without fearing for my life.
Milwaukee... have you noticed any difference in the tranny temps when you swapped tires?

Jank..
I haven't noticed a difference in tranny temps. I didn't have any controlled measures, but the tranny temp before in 20-30 degree driving on a long high-way run was about 149 (just a tick under 150)
With the bigger tires the tranny temp is the exact same on the same trip, same temp.
I think perhaps in stop and go traffic it might get heated up a little faster, but running temp still seems to be abotu the same.
Same with gas(fuel) mileage. I think on the freeway I lost a mpg or so.. in stop and go driving I think I lost 2 mpg. Well worth it...
It looks like a real truck now.
I get compliments on the truck. With the conti's it looked like a grocery getter.
