I'll probably get Duratrac too.
For both on/off road and winter
I can't afford switching them and more than that, i wouldn't have space to store them
In my case, i'll switch the rims with some 15" steel rims (or most likely 16" because of bigger disk brakes on Sahara).
They steel ones are be better offroad as i already damaged the factory ones on some trails ...
And about the `bigger tires` my Sahara came with 32" tires (255/70R18) so without any changes you can go up to 32" without problems.
I know somebody running 33" with minor rubbing offroad.
EDIT: and if you find a good deal on your new tires, please let me know
I live in Montreal so i'm be interested.
JH- the brakes are the same diameter on all JK's- Sahara and X and Rubicon all run the exact same discs. The calipers are what cause interference, and with MINIMAL grinding, you can fit 15's on any JK (I do! )
Ok- I'll dare to be different here. I live and work at a horse farm, so missing a day is not an option. Here in upstate NY, I run dedicated winter tires on my rig. All-terrains are alright for most folks, but when you can't afford a stuck day, winter tires are the only way to go. Adding studs varies by legality- they're illegal here, as they chew up the roads (which are already crap to begin with). Check with a local tire store if they're legal in Montreal- they'd be the guys who'd do it.
Get a set of cheap steel wheels and winter tires, and be worry free- check out various types on tirerack.com Great site, great folks! Mark W.
