well im looking into some new tires for my jk i currently have a 2 door rubicon with a rk 3.5 x factor mid armlift and xenon flat flares im running hancook dyna pro mt 315 70 17 im looking at going to a 37-40 range i do use it as a daily driver but i drive 1/10th of a mile to work i do enjoy rocks but on the trail i do see a little bit of it all so heres the tires ive debated now i just need some advice ive lookedc at the km2 37/12.50/17 and a 38/14.50/17 mtrs in a 37/12.5017 and 40/12.50/17 and falken wild peak ats in a 37/12.50/17 and also the mickey thompson mtz in a 37/12.50/17 and the open country mt in a 37/13.50/17 so heres what im looking at now some advice and if 40s are suggested what i may need to do to get these tires to work i have an idea but not completly sure

 

With your lift I would stick with 37's and go with Toyo mt's or Nitto trail grapplers. They are great on and off road and will be the most durable on the rocks

 

I love the mtzs but the km2 are the best on the road. The toyos are super heavy and will rub with their additional width. With the lower on road driving like you desccribe i would go with 37" Mtz followed by the nitto trail graps, then the km2. A lot of people dive the toyos but for me the extra weight weighing on your engine and axles and the rubbing are a turn off

 

The weight and size factor scares me I really want the km2 in a 38 but the width scares me

 

Didnt know the km2 came in 38. The width on km2 is legit 12.50. The toyos are closer to 14" and are really made for trucks (per toyo rep) the nitto trail graps are actually over 13" wide, that is whats on my jeep. Had the km2 in 37" but they were closer to 36" than 37" thats why i went nitto. Much closer to a true 37"

 

The km2 comes ins38/14.50/17

 

Here's my jeep now

 

My bad, was only thinking of the 12.50 family. That width is too much on the jeep. After a few more wheeling trips i am going to compare ground clearance and if i can get by with the 0.5" less on the km2 vs the nitto, i will go back to the km2. I like the narrower tire on road and they last longer
