I had 35's on my 05. I had 3.73s and I didn't have any problems with towing. I towed a 14000 pound goose without and problems with that setup. Its just up to you. 4.10s your gunna get worse fuel milage.

Thanks for the quick reply.

Would the fact that the 4.10s bring the ratio back to stock with 35s help the mileage when I go to the bigger tires?

How does everyone else with larger tires feel?

Thanks again...

Are you going to delete or are you going to leave the emissions intact? You are going to have regeneration all the time with that short low speed freeway hop. I am 8 to work with 5 slow freeway. Had to drive another 30 to 40 miles every other day to get the regens to complete. Then I "repaired" my emissions to make the truck run correctly. If you are going to stay stock get the 4:10 to keep engine speed up, drive in tow haul mode or even manually shift to keep rpms way up.

I'm going to delete after the warranty is up, maybe before that if there are big issues. I'll be sure to drive it on longer routes as well. 30-40 extra miles every couple of days sounds pretty bad.

Well 1 vote for the 3.73s and 1 for the 4.10s. I'm leaning toward the 4.10s but still not 100% decided. Thanks for the info!

I am happy with 4.10 and 35's on my truck...

I'll take 4.10's any day of the week. I can still go 80. I like the lower gear with the larger tire. JMO.

i will never buy a truck with 4:10's but thats just me. i have 3:73 an 285's on my truck an so far they are treating me just fine. the fuel mileage sucks as it is i wouldnt want it to get any worse with 4:10's just IMO though

 

[OSUmaxx]

Thanks for all of the info... the dealer is having a hard time locating 4.10s so we'll see. Great replies though.

 

[dzlbudman]

Where are you located? Oklahoma? If you are theres a dealership in my town that has 2 trucks with 4.10s
:shock:

 

[OSUmaxx]

Thanks, but I'm in the northwest so that's a pretty long drive!

i had an 04 with 3.73's and 35's with an auto. that was a garbage combo when pulling heavy unless you wanted to drive 60-65 tops out of overdrive. In overdrive, you would have to drive 75-80 to keep it in the good rpm range and IMO that is kinda fast with a big load. I since have purchased a new truck with 4.10's and have 34" tires on it. The combo is good IMO.

Here is a good gear calculator so you can figure out which gearing will be best for you Gear Ratio Calculator

Are you getting an auto or a manual tranny?

 

[OSUmaxx]

Thanks, great calculator link. Going for the auto. Found a deal on one with 3.73s and although I'd prefer 4.10s, I might run the stock tires down with the 3.73s and upgrade later...

4.10's!!!!!

I had to get my dealer to look elsewhere in alberta for my truck because of the 4.10's. Mind ya i got 37's, but even stock size tires my vote is 4.10's
