if u didnt see i recently went to 35's and im currently running 3.73's. after doin previous research ive known id have to change gears to 4:56's or aleast 4:10's. But ive been drivin around lately and it feels good for my drivin style. i was runnin about 76 mph on the highway at right around 2150 2200 rpms... umm im pretty sure thats damn low for a 3.0 and gonna me prime for gas mileage. so am i wrong or my truck playin tricks on me

 

your low end power is going to be lacking. Top end whould be fine, but for off roading its going to struggle. How long does it take you to go from 0-60?

 

Are you a manual or an auto? I would think you are going to have serious trans problems in the future if you are an auto. It is going to put alot of stress and load on the tranny, heating it up quickly and excessively. A manual you could get away with it, but be prepared to replace the clutch sooner than later.

As well gas millage is not exclusively due to RPM's. It is where the engine is most efficient.

 

i got a manual. i personally like it. i never off road and do about 85% drivin at a constant 50-65 mph. and i never take off the line cuz hey i got a 3.slow so why bother.i im no hurry to get anywhere if that helps lol

 

If you dont mind me asking, if you do not off road, then why 35's?

 

i feel ya. old worn out 4.0 OHV with 3.55s

and my 9" takes more power to turn.. I can cruise at 3-3,500 at 75 in 3rd gear

5th is wayyy too low (high?)

 

why not?

 

Well I mean I not here to tell people what to do or how to spend their hard earned money but it just seems like a waste of money in my book to buy tires that big and not really use them. I just do not think that you would want to loose that much mpg's if you do not really use the tires. But hey, opinions are like *** holes, everyone has one.

 

Whatever floats your boat though
