TexasT It's great to have you on board. I've had 2 cjs and a yj but the TJ is by far the best because of it's versatility and ease of working on. You will enjoy.

TexasT Complicated? Its fill in the blank. If you know what transmission you have it fills in the gear ratios for you...same with Tcase. It already has ALL the transmissions that jeeps have so you don't need to know their gears. It also has jeep Tcase options so you don't need their gear ratios either. You enter your jeeps axle gears and tire size and you will see performance at 65 mph. This is basic info that I see people asking in the forum all the time. Knowing this data is basic to making changes to your jeep. spend a few minutes putting your jeeps driveline then put in other tire sizes and see how it effects the hwy speed or crawl speed.

You've really done your homework selecting a jeep, this is homework for making modifications...especially simple changes like tire size.

Enjoy your new jeep!

AWESOME! I was hoping this would be the case! If the Jeep is stock gearing with no lift, what would you expect the range of wheel/tire sizes to be useable? Thanks!

Thanks. That site was WAY over my head!

NOOB Gearing Questions...

So I hear alot about gearing on this board, especially in relation to tire and wheel selection. Just wondering as I ponder my first Jeep purchase, how do I know what gearing is in place when I look at perspective rides? I'm assuming that Jeep gearing is similar to sprockets on a motorcycle, which I know more about. Unlike a motorcycle which you can see and count the teeth, figuring this out on a Jeep seems more mysterious to me.

Right now I'm closing in on a 05 X. Anyway to tell what the gearing is before purchase? If not, does anybody know the stock gearing and the range of wheel and tire sizes that work well with this model?

Thanks, Peter
