At least you don't have to worry about blowin' a tire!

 

Got 37s this Jan. Went through the whole, Toyos, Nittos, and KM2 consideration.
Ruled out KM2, and went for the Nittos. They are 1" thinner so no spacers for me and a little more flex than the Toyos and slightly lighter than the Toyos.
The carcass on the Nittos are same as Toyos, so should be tough.
I've put on about 3K miles since, rockcrawling and highway. Couldnt be happier. They are pretty quiet on the highway as well.

You probably know this, but if you go 37s, youre going to have to beef up your front axles, housing, and Cs at a minimum.

 

Yours are lighter than air Reminds me of the first Star Wars movie

 

I had KM2’s and ran them for years. Played on the rock and anything else I could find. I had total confidence in them and abused them to the point that the raised letters on the side wall are gone from rubbing on the rocks and stuff. And 75% of people I go wheeling with use them without a problem. I did try a set of Toyo’s this last time and I feel they stick better on the rocks and I have not had a problem with them either. FYI weight always matter, but even more with the smaller 30.
