the only place I am aware of is http://www.ricksontruck.com/

if I were you I would head more to a highway tread if possible...fits yer application better I think

 

My first set of tires was the yOKAHAMA ty 303 AND THEY WERE VERY GOOD TO ME.......THOSE WOULD PROLLY BE YER BEST BET FOR HOT SHOTIN

sorry caps lock got me

 

no prob thanks for the info

 

the 225/70/19.5 should be close to the same height as stock tires around 32 inches. the bigger the tire over stock the more your truck will lug, so it would be harder to pull the bigger tires, dont know how much weight ur pulling but my dodge pulls 40,000 through the small hills better with 215's than 235's

 

you have a manual or auto tranny .........makes a big diff

 

the 225/70/19.5 tire should be about the same height as your stock tires which will keep the pulling power close to what u have now, I now mine seems to pull better with 215's than 235's just my personal experience

 

i have a 6 spd manual tranny.

 

excellent........I wouldnt hessitate going to a 35-36 inch tire............this will work great for ya

interstate travel at 75 you will need the mph to keep yer rpm up.......I think I run 1900 at 75 mph.........jam er into 5th and there aint a hill around ya cant take

 

hell yah, she does good stock loaded down with 20,000 lbs of thick wall pipe as is. so i will go nuts. to get them big wheels on there.

 

I am running 22.5's on my truck and it is by far the best thing I have ever done. I have a 6 speed manual and the gearing is now perfect.
Couple things to consider if you do 22.5's Rubbing isn't a issue in the front. But it is in the rear. Air bags took care of that problum.
Front adaptors get from arrow craft incase you ever want to put in a dyna trac free spin kit.
I went all aluminum rims saves a lot of weight. But the adaptors need longer studs. no big deal they are at every truck shop and they are cheap.
I was going threw 6 tires every 18 to 20K. I have about 50K on the 22.5's and the way they look 200K should be easily possible.
