I might have a deal worked out trading my rims and tires nitto trail grapplers 295/70/18 for a set of nitto trail grapplers 37s is this a good idea since I have a Dana 30?

37's is too large for a D30. Even 35's is pushing it.

You could reinforce with a sleeve and gusset, but I still would never go larger than a 35.

Do it! Lots of guy run 37" tires on their stock axles with only Sleeve and Gussets. Hell, there's guys running flat fenders, 2" bb, and 37"s.

Regear would be suggested though, you'll lose quite a bit of power, but if you don't care about power go ahead. I'm planning to.

I'd do it. I have 37's on a D30.

Totally off topic but how do you like those tires and that setup? I'm looking at the exact same tires on the stock Sahara wheels.

That's one thing I am concerned about is the power loss as I don't have money for a regear I do have a 2012 so that should help some. Plus not sure how it will be with the 2.5 lift rock krawler say u can run 37s with flat fenders so it sounds like it's doable just concerned with power loss and how the Dana 30 will hold up looks like many guys do it no problems. The guy will give 5 wheels but only 4 tires for my 5 stock wheels and tires plus 300 is that a good deal? As far as the tires go I like them a lot they perform great not loud on the road and they look bad ass.

Happen to have any pictures??

did some research found the 37's weigh 8 more pounds per tire than what Im currently running.

i love watching guys try and justify 37s on stock axles....on dana 30s at that,in no way shape or form can a dana 30 even be built to wheel 37s reliably...sorry,thats just the truth of it.i run custom built currie d44s, 35 spline cromo shafts,arb air lockers ,cryo 5;13 treated r&p & i still break stuff on my 37s.then theres the steering brakes and a whole slew of other crap that has to be addressed.do yourself a favor,look into what it takes to run 37s correctly,build your rig for them and then go with 37s,trust me,it will save you a lot more money in the long run.
