please bear with me im new to all this and trying to understand everything i want the best for my truck i have a 99 xj limited with the 4.0 engine and the dana35 so ive red on here that re gearing can b a really good thing to do this is my every day truck so want good street performance but still have good 4 wheel capability can any explain why or when is a good idea to do it or not and any pros or cons

 

When larger tires are installed, the vehicle takes more effort to get them turning. Highway speeds will suffer as will gas mileage. Regearing will regain the power and fuel mileage lost because of those big tires. Are you running on larger tires? If so what size are they and what is your current gear ratio? If you do not know, take a look at the tag on the rear axle. If the tag is missing we can go by the normal standards for each Jeep. Do you have a automatic or standard transmission?

 

i dont know it i looked the tag is missin so i have automatic and i dont know if this helps but i i plan on runnin 22in rims with some meaty tires dont know excactly yet for the hellified potholes in the spring summer and 30 something in the fall winter i live in chicago so i need some good street performance and 4 wheel help year round

 

If you want good off road performance 22" rims are not the way to go unless you can run a 44" tire. The rule is that the rim should not exceed half the tire diameter. Off road tires need to flex and they can't do that without adequate side walls. I know they look cool, but they are not for Jeeps.

Generally you can only run 30" tires on stock wheels without rubbing without trimming fenders or lifting. You can go t a 31" on stock wheels with a 3", 33" tires on a 4.5" and mild trimming.

 

i understand this is mainly a 4wheel forum but i mostly thought a jeep lover forum witch i am this is my third and best 1 yet and gettin better with great help from all of u and i do plan on gettin a dedicated 4wheeler but this one is for both mostly street so if u can please help me on that well i do plan on getting a 3in lift to and the 22s r for for summer and switch in the winter to the 30 something what ever size is the best overall street n bad condition

 

Do you know the size of the tire for the 22"s and what size you are looking for on your winter rims? Knowing the tire size will help get a better idea of the need to regear or not.

 

sorry i try do overall research first.... so no not yet i know i want meaty tires but not to big and not to much on the low profile side cuz of the bad streets and dont want to crack rims or drop suspension parts in the chicagoland area runnin over those basements with no house over them oops sorry i mean potholes and i do almost all my daily commute 60% on the eway so for winter driving i want what ever 30 something size is good all around street and off road performer for the winter in thoes conditions..... id like and im trying to do the mods the right way performance and reliablity then looks

 

Since you have a 4.0 and an automatic, your stock gearing should be 3.55. With a 3 inch lift you can run 31 inch all terrains or mud tires. All terrains would give you a smoother ride and will more than likely have a little better traction in the snow than most mud tires. With a tire that size I don't think a regear would be absolutely neccesary. If you wanted to feel more power from the skinny pedal, then go ahead and have it changed to 4.10 gears.

 

22's and 40's would be sweet! I know a guy that has 42's on his XJ, but on 15's. Good luck and post pics!

 

fitting 22" rims under a 3" lift is still gonna leave you with really low profile tires and ruined rims, no two ways about it. 17's would be pushing the envelope with something like 245/65R17's but you still might get some rubbing. you might want to come up with an alternate plan in regards to da bling, that's going to be a tough fit!

 

thank u all very much for the info my not set in stone plans was 22in rims and 17 with 30s but will change my ideas what ever is best for my truck and performance

 

Hahaha, 22rims with 44 tires! lol!

 

LMAO!! no u misunderstood although 44's on a jeep could look sweet the 30 something inch tires will not b on the 22 in rims the 30+ tires will have diffrent 17 or 18 inch rims
