Can I do 33" Tires with 3.73 gears?

I have a 98 Jeep 4.0L wrangler and Im going to put the 2" BDS suspension lift on it and im just looking to see If I could do 33" tires with it or would it be better to go 32". I currently have 31" with no lift of any kind and im fine.

This is a jeep thats driven 98% of the time on the road and no major off roading.

Thanks

There are several members on here that run a 2 inch lift with 33 inch tires along along with the 3.73 gearing. It is not a good set up for driving off road but since you are only driving on the street you will be okay. You may get some rubbing on steering but you can fix that with the steering stops. Don't go fast through big dips or speed bumps either.

On the road you are fine. With regards to the 3.73, you are also fine. That what I have with the automatic.

I'm running 33" tires with 3.73 gears but mines a 6 speed and no problems on road or off but the 6 speed is geared lower than the 5 speed.

I have it in my automatic with 33's, you can run that but it's not the best idea or the worst really, it's sluggish up hills and your rpm's will stay low but you loose power not regearing I bought it like that and I am in the process now going to 4.56 wish I knew better but you live and learn, I haven't had problems offroad with it but i'm also not doing anything like the Rubicon it will work but you should look into regearing in my opinion

I'm running 33's with a 4.0 and 6 speed manual with tall ass 3.07 gears..... not ideal but it works. You'll be fine.

With 3:73 gears and 33" tires you are fine. I have the 3:73 with 33" tires and have no problems, sure I'd love to have 4:10 or 4:56 gears but I'd just start snapping axles and such. You'll just have to drop a gear when going up hills to maintain your speed.

I would really recommend 4.56 gears with 33" tires and the AX-15. I changed from 4.10 gears and it is a big noticeable difference both on and off road.

Those are nice looking wheels.

Regarding the OP's question. I have 33s with 3.73 gearing and a 4.0. (NV3550 transmission) It's ok on the road, but I noticed the higher "gearing" when offroad. I miss my crawl. But I've planned on regearing from the beginning. (Before the lift and tires.)

I always suggest: put the tires on, if you don't like it after 2 weeks, regear. I think you will be happy with 3.73s and 33s.

i too have 33s with 3.73 but 6 spd manual i don't have any rubbing because i replaced my stock ravine wheels with a set of rims that has 3 5/8" of backspacing

mine is a 2000, tried to look at the tag and its rusting off but from what i can see i think the ratio's last number is still visible and it looks like an 8 which i figured had to be a 3 bc there is no way that it has 4.88 gears lol so i figured 3.73 was logical. i honestly don't think that could be a 0 on there but maybe i'll have to look again.

Okay, you should have the 32rh transmission, which is a good thing as it has no overdrive. As far as speed is concerned when you go with a larger tire in diameter then your speedometer should read lower than your actual speed. For example, I went from 30's to 33's and my speedo reads 63 when I am doing 70.

I have 33s with stock 3.73 gears. I6 and 5 speed manual. And no 5th gear when going up any type of incline greater than 0.00001 degrees. Re-gear is numero uno on my to do list. Don't get me wrong, I get along fine in 4th gear, but I sure would like to get that one extra shift in every once in a while.

I run 3.73's and 33's myself. I lose a little power on inclines but not that noticeable. We drive Jeeps not race cars. Probably around 2000 rpms in 5th gear at 65. Hope this helps.

yeah it does help thanks, i finally stepped out of the baby jeep stage haha, took me a yr but it was worth it, now i'm just looking at a 2in leveling kit to get me a lil more room on my front fenders. i honestly like the way i sit right now enough to hold off on a full lift for a yr or two. plus as high as i sit now with just the 33's and Rubi wheels i think 2.5 is more than enoug for me and my style of off roading. you guys helped alot wit reassuring me that my 3.73's are fine. i was worried i'd dug myself in a hole and needed new gears and possibly axels. mahalo! and much Aloha! shaka bruhdah!
