i have 325 65 18 they measure around 34" and i hear everyone saying 356's but i dont know if i want it that low i drive a little on the highway but its not like i need to cruse at 80 anyway and i pull a lanscape trailer around town frequently and im really concerned with gas milage any feedback would be great thxs mike i have 373 now i wanna try to get it back to stock

 

Your tires are actually closer to 35s than 34s. I assume when you said 3.56s, you meant 4.56s? As far as I'm concerned, 4.56s would be perfect. I have 4.56s with 35s and it's a great all-around combo. I can tow, cruise on the highway, and drive around town. The lower (numerically higher) gear ratio you have, the happier your truck will be about towing (within reason. of course). 4.56s will put you slighly above stock RPMs, but you said you don't need to be cruising at 80, so it's all good IMO.

With 4.10s you will still be a bit lower than stock. 4.56s will be a bit higher. It's all about what you want. If I were you, I'd go 4.56s.

 

Oh and that's a sweet looking truck. I just hope that's not like tranny fluid leaking out there lol.

 

Going from 3.73 to 4.10 on 35s is a complete waste of $$$.
A "one ratio" jump isn't worth the dough in most cases, as the improvement is not significant enough to notice.

You're going from crappy to slightly less crappy.

Search this site to find many, many people who are thrilled with 4.56 on 35s... I don't think you'll find one unhappy person.

4.10s are for street-sized tires...tires closer to stock than what you're rolling on.

 

thxs for everyones opinions it really does help

 

I agree the 4.56 ratio with your 35's would put you where towing the landscape trailer around and daily driving would be great.
Oh yea, that's one SWEET A$$ Lookin ride.
