|drbandkgb||The biggest loss in power is due to the type of tire your running... If you went with a KO I dont think you would notice.. or maybe a Duratrac... When you start running big lug tires its going to take more... ATs have less rolling resistance I have 32 KM2s on my 90 YJ.. I had 35s on it.. talk about power loss|

I just installed 31 X 10.5 BFG KM2's on my stock rims along with a 2.5 inch Rough Country lift and spacers up front to level it out. It rides great, there is definitely a loss of power (My stock config was 225/75R15 I6 4.0 and 3.07 gears), but nothing I would regear for.
It is still quite nimble and I'm glad I made the change. Someday if I want more I'll add a body lift, regear and 35's.

|Dewry636||Yah, I just had 31 X 10.5 BFG KM2's installed on my 97 4.0 5spd wrangler with 3.07 gears and I definately notice the power loss.... I may re-gear later but for now, it's ok.|

|drbandkgb||I wouldnt re-gear till 35s|

|oIIIIIIo||I am running 31's now with 3.07 gears. Not that great with all the gears that I have added. I am getting a D44 rear with 4.10 put in tomorrow and install 33's on it also. It will bring the hp back to the Jeep.|

|Ektarr||I just put 31x10.5x15's on my '05 TJ a coupl'a months ago. BFG KM2's. They're fine with no gearing changes at all...great tire, if a bit noisy. Look better, too, with no lift.|

|JDsDream||You will be fine going to a 31x10.5. Anything larger and you may encounter a little rub on sharp turns. As far as gearing is concerned, you will be fine with the 31's.|

|ReconBubba6||Is it bad to regear for 33s if you only have 31s but plan on getting 33s later?|

|tlarm139||thanks everyone.it is my daily driver and i offroad every now and then but its nothing intense, so ill see how it feels. a lot of people have been telling me i dont have to with 31's so ill see. thanks !|

|yjkid95||The rubicon came stock with 31's and 4.10 gearing. So 4.10's would be optimal but is it a nessecity? No. Its mainly up to you. After you get them on drive around with them and if you like the way it feels leave it alone if you feel you want more power then regear to 4.10's|

|RubiCobra||No need to re gear for 31's. Wait until you're ready for a set of 35's, then re gear. Or possibly 33's, if that's as big as you ever plan on running.|

|InfernoGirl||No. Not as far as I can tell.... What size tires do you have now?|
|01-15-2011 12:41 PM|
|InvertChaos||What engine and gearing do you have now? I wouldn't think you would have to regear for 31s|
|01-15-2011 12:40 PM|

Okay so im getting my lift and tires soon. Do i have to regear if i upgrade to 31x10.5's?
