I see a lot of people with 12.50 tires, but not too many with 13.50. What is the big difference besides price? Do 12.50's articulate more or what? I'm having a hard time deciding...

 

About 1" :-)

 

I got 13.5 LTB's and the tread width size was the same as 12.5, but the overall width at the sidewall is bigger. Gives you a little more floatation, I guess.

 

If you went with 13.5, you'd notice the difference in sand for sure, quite a bit in mud, not so much in rocks or gravel roads, and your miles would suck even worse. Other than that, not much difference.

 

Hah well thanks. I suppose that basically sums it up.

 

Uhm... 13.50's are awesome? Sheesh.. didn't you know? =P

 

Sometimes its just what that tire company decides to produce. Some lean more towards the wider 13.5, while other stick with a more traditional 12.5.
Also, I would think that some wheels couldnt handle a 13.5, while a 12.5 would fit, even if it was a stretch.

Mine are 13.5 in wide, but only beacause thats what was available in the tire I wanted for the wheel I wanted.

 

Another reason the 12.5's may be more popular is because most (maybe even all) brands can be used with the 7.5" wide stock wheels.

 

pretty much what everyone else has said.........but when you air down you are going to have a larger footprint with a wider tire.....you will be happy with either.

 

That was my answer... Always at least one smart donkey around.
