I plan on getting the rock krawler 3.5" entry level mid arm lift. On there website it says with flat flares you can run 37" tires. So I've been looking at bfgoodrich km2 and heard they run a little small so does that mean I could actually run 38" tires. I have a 2013 unlimited rubicon. Thanks all help is appreciated!

 

I would stick with the 37's with that setup. You could make it work going bigger, but I would rather have the extra room between the tire and fender

 

I agree. Also, what gears are you running?

 

Stay with the 37"s like other said better to have the little bit of extra room

 

I have 4.10 and a manual

 

Shouldn't be too bad with the 3.6. Over 37" would make it a dog though

 

Bump. Any other opinions?

 

Bump bump.
