Am planning to fix 35" tire on my jk sport 3.73 ratio. Any advise

 

what exactly are you wanting to know? what year is your jeep and is it a 2-door or 4-door? for the most part, 2.5" of lift or there abouts will get you clearing 35's but, answering the other questions will help.

 

2012 , 2 doors, 2.5" kit . They told me that the car will not run the same.

 

It's a Jeep not a car.

It will not run the same. It will be slightly slower during acceleration, and if you have an Automatic transmission it will most likely not hold 5th gear going up an incline or a hill.

That said....35s on the new 3.6L Pentastar....which is the engine I am assuming you have would be OK with 3.73s and pretty darn good with 4.10s.

If you have some other engine like a deisel, I cannot comment on how it might perform. Also....you might need a AEV Procal to adjust your speedometer.
