Tire question

Hi all,

I have a 2011 access cab 4x4 with about 2700miles on it. I have been using the truck recently on forest roads (nothing crazy). I noticed this morning that all four tires seem to be starting to bubble out on the sidewall. There aren't any bubbles yet but I can feel and see where the seems are weakened. My question is, is this normal or should I be worried about it since I will be using these tires quite a bit on forest roads for the next 6 months or so.

any help would be appreciated,

Thanks

what the thoughts on this tire size. i have reg cab 4x4 3" lift, pizza cutters sound cool however not sure if they will look any good?

 

WHAT tire size? And what does this have to do bubbling sidewalls?
