Just mounted my NTG 305/55/20's that I got from Ramhunter.
Thanks RH.
Needed to use 1/4" spacers. There would be no way they would fit without them. I got about an 1/8" left of clearance. Real tight fit.

What PSI do you guys recomend for everyday use? They are E rated and max is 65, but that doesnt sound practical for everyday. Shop put them at 45, but that seems too much too. Seems like it would wear out the middle. What do you guys run at?

Also, for those of you with SC and this size, did you adjust tire size on the tuner? What did you adjust to? The stock 275's measured at 31.5 on the truck and that is the stock setting on the SC. I measured the 305's at just over 32. Should I adjust?

Thanks guys. Kinda weak pic, but i just got back from the shop and wanted to ask these questions right away.

 

get a level

 

Haha. knew that was coming, but I thought get a wash would be first.

 

Set it at 33.25 on the chip. The overall diameter is 33.2

I've run mine at 40PSI for almost a year with no irregular wear

 

they look better on your rig than they did my buddies ....no $hitz

he ran them at 50 psi since day one and as you can see they are all evenly treaded .
i ran the same tire in a 35 with 50 psi no problems and the 37's are at 50 aswell

and yes alberta is spot on with the tunner .

 

also agree a level would be awesome . you need to post pics of that sick azz hood

 

truck needs a level . Go with 2inch bilstein struts they raise it two inches and you wouldn't need the spacers.imo Plus you get a decent shock in the spring instead of the piece of shlt dodge calls a strut!!!

 

Oh yeah....level is next on the list. Just got the truck about 3 months ago and have been doing other things. But since the weather is getting warmer, its about time to get out in the driveway with some beers and get her leveled.
Im confused about the tire size on the tuner tho. I know the tires measure 33.07, but shouldnt the adjustment on the tuner be the size of the tires at the proper PSI with the trucks weight on them? thats 32". I get diferent opinions on this.
BTW, heres another pic with the hood that RH was talkin about.

 

OOoooOOoOOOoOoOOoo sweet hood dude.

 

Well my speedo with the exact same tires inflated on my truck is dead on at 33.25...
Matches up to two seperate navs that list the same speed the speedo registers.
