New here, but just a quick question. How will 22.5 alcoas with 255/70/22.5 tires affect my truck. 2007 QC DRW 4x4 6.7L 6spAuto with 3.73s. Don't really do any hauling just alot of city and highway driving unloaded. Will I need to change gearing to the 4.10s or will the 3.73s be okay. What kind of mileage may I expect. Purchasing tires, wheels, and adapters from American Force Wheels in Miami. Any help will be greatly appreciated, thanks.

 

3.73's, 22.5's, and no extra power you might be unhappy. I have got some serious fuel and the 22.5's slowed my truck down a good deal. But it would look good. Just be sure you are ready for some power loss, the only good thing is you have 6 speed auto so it may have some lower gears than the 48re and help you get up and rolling. Give it a shot and let us know how the 6 speed tranny does.

 

I have 3.7 in my truck and they are still really low and have no problem with it at all, the key is the 6spd, however like rye i have alot of engine mods. Also try not to take as long as Rye did to decide if they are on your mind just get them and I am pretty sure you will really enjoy them, hahaha Rye

Oh thats funny, what Mr.Wiggs is off so now you get to pick on me .
But seriously that would be cool to see how the 6sp auto handles them.

what happened to him

 

I thought he posted about going out of the country for a while, I have no clue. I thought you were under his bed so I thought you would know.

 

Ya I had fun teasing him but it was all in fun.

 

I know, it sure made me laugh.

 

A friend of mine got a 07 with the 6 speed auto and his rpms are lower then my 06 manual with the 37's You are going to wish you had 4.10's

 

just wanted to thank everyone here for their thoughts and comments.

 

My 2004 is totally stock mechanically. I do have the 4:10's with the 48RE and did notice some slugishness when I installed the 22.5's. I don't haul anything, just tow my 24 foot enclosed car trailer. I don't really miss the extra ommph, because the looks seem to overcome that. All in all, I am happy with the conversion.

 

The new 68RE trans has a really low overdrive, so your power and mileage will really suffer with the new wheels and tires.

"rstone" on here went to 20s and 305/50s and it dropped 4mpg, even when he installed a Edge Juice w/att it didnt help, he still got around 14mpg and that was in a single wheel short bed 4x4 all hwy driving....

He now has a 5.9...... again
