Okay to start it off. I have a 2011 xlt 3.7. It's mpt tuned (Performance/Street). It's currently leveled with fox 2.0 shocks and coil overs in all four corners. I'm adding a 4" spindle up front. My question is. Can a tuned 3.7 turn a 35" tire? Mostly street driven. Mild off-roading.

 

Sure, why not?

 

No idea why it couldn't. No doubt it can fit it. The difference in weight from the stock 32 isn't that drastic in comparison to the power of the truck.

 

You'll need to re-gear but once done, it should be fine.

 

Yeah, shouldn't be bad. MPG's will go down a bit and your acceleration won't be as good but it would work.

 

What gear ratio do you have? Can it turn them? Yeah, I'm sure it can no problem. You'll feel the extra weight for sure and the truck may not get up and go as well as it does now, but that's the same with any engine really. You have coilover's in all four corners?!!!!!!! Let's see that custom rear suspension. jk
