Hello everyone. I have a 2010 Mango Tango Ram Crew Cab 4x4, it is stock for suspension and tires/wheels 20".

I was looking at getting the Mopar 4" lift and I really like the American Outlaw Hollywood wheels and I would stay with 20" and I have not decided on 35" or 37" Nitto Trail grappler or terra grapplers.

I wanted your advice/opinions on this. Here are some questions I have;

if I run 37's, should I get negative offset wheels?
If I run 37's would I need to change the diff. gears?
I would be doing mainly road driving with little off road and by that I mean just driving across some farm fields, nothing outrageous, so should I stay with the Terra grapplers or would the trail grapplers be ok. I do not want to spend $500/tire only to have them wear out in 40k miles.

I would add wheel flares down the road so offsetting would not be a problem. I was thinking the Mopar 4" lift so that I could have the dealership install it.

Let's say I decided to go with a different size wheel, I know I could go as low as a 18" rim but, if I do would this mess up my speedo?


Thanks everyone, your pics of rides give me inspiration and your comments are greatly appreciated.

I need to get more pics of my truck but here is the only one i can find right now. As you can tell, I am a big fan of the color orange.

 

If you want to run 37's,then you better go with a 6" suspension lift.35's with a 4" lift......When i had just the 6" suspension lift,I ran 35x12.50R18 Nitto Mud Grapplers,with 18x9.5 Helo wheels having a 4.5" backspacing....Now with a 3" body lift added to the truck,I run 37x13.50R18 Procomp x-terrains,along with 1-3/4" wheel adapters,(not really needed)but installed them to bring my wheels and tires out further.Good luck on your decision...depends on how much you are willing to spend...

 

For whatever it's worth, I did a 4" Rough County and put on 35" Terra Grapplers on my stock 20"s. I'm very happy with it. And yes, if you are thinking 37" - I'd go with a 6" lift. With this setup, I did have to do 1/4" spacers all around to prevent some rubbing - because these are big tires on stock rims. You could probably avoid spacers if you get different rims.

Prepare for a significant reduction in mileage too. I expected some ... I've gone from 21 Hwy to 14 Hwy. Something worth considering considering the cost of gas these days!!
