Gears for 24's???

[Mean Green]

It has 275/30ZR24.
What would have come stock?

More then likely it came stock with 245/70R/16's, you can take a peak on the side of your drivers door and it should say what it was equipped with originally!

So I tried the tire hieghth calculator and it shows about an in taller for my current set of wheels.
Is that a big difference?

Well an inch isn't that big of deal really, but you went from whatever size tire your truck was originally equipped with to the 24's you have now. So in reality you did make quite a bit of change in size. Now if your tire is a 30" like you said earlier, then if you upgrade to 3.73's i think you will be happy with it! I have 3.73's in my truck and my tires measure just shy of 32" or so, and I'm at about 2000 RPM's at 70, and about 1600 rpms's /at 60

Yeah, I just want some of the performance back. Just so it doesn't feel like going backwards when I get a tune or anything else. Thanks for your help guys. Gonna order some 373's and a posi next week.
