      I have goodyear wrangler rts i think on my 2000 xlt. It came on the truck from the dealer and looks brand new. ive put on about 1000 miles so far. and just today noticed slight rippling on the sidwalls of 3 tires. by rippling i mean almost bumps but very small, like half a centimeter sticking out along the sidwall. Does this mean anything? someone just told me that this is normal for the wranglers... but i dont know if itz cus of underpressure or overpressure in the tires. I run about 34-36 psi . any ideas? hope i dont need new tires...

      go to a tire place and ask them..... if there are bubbles in the sidewall that could lead to a zipper failure... that aint good...... then again they may just be seams from different belts being pieced together and that is normal...... are they cracklike and run with the circumference of the tire? or do they only run from the rim straight to the tire tread?

      they arent cracking.. the ripples start from the rim and go to the threads.. in very thin strips..

      than its probably just the tire belts at the seams.... nothing to worry about if it is.....

      It doesn't sound healthy. I'd have them checked out manana!

      EDIT: do they look uniform or are they spuratic? The only thing that doesn't make sense is its only on three tires.

      i guess the easiest way to picture it is by look at the tired from the side view of the car... pretend ur karate chopping the tire ..the mark ur hand would leave on the tire is the ripple.. and there are a few of those per tire...

      oh yeah, forgot to ask, are the ripples inward toward the frame or outward toward the curbs? if they are inward, then your probably ok.... since i cant diagnose this without seeing your truck, go to a local tire place and ask them... you may need to go to a few different palces to make sure they arent trying to scam you into a new set of tires.....

      all this is is a cord splice. you will be fine. if its a round bubble, then it is an open splice and the tire will fail. but, from what you have described, it is just the splice. it is in all tires, but the thinner the sidewall rubber, the thicker the cord, the more noticable it will be.

      so i got my tires checked it.. the person said itz not that bad. and that i shouldnt be worried at the moment. but he said that i should watch out for the ripples to get any larger. he said that the metal wires on the sidewall are bulging because of the potholes in the streets. the tire tries to compensate too much.. and starts to expand sideways. i avoid almost all potholes.. i guess these tires just suck.. wrangler rts... he said i shouldnt expect more than 25000 miles out of them.. my firestones lasted almost 60k. dang.. but the bridgestone dueler a/ts, the new ones.. look pretty nice.. and $576 from the firestone dealer with mounting and balancing and insurance doesnt seem that bad. hopefully i wont have to get them for a while.. :p

      sorry to tell you this, but your tire shop guy doesnt know what hes talking about. the "metal wires" are belts, and they are NOT on the sidewall. the belts are under the tread. the ONLY thing in the sidewall is layers of cord, and the sidewall rubber itself. a radial tire will not try to compensate for pothole abuse by expanding sideways. what you have is a tire with fairly heavy duty cord and relatively thin sidewall rubber. this lets all of the cord splices show through much worse than normal. all tires have these, but due to design some just show it worse than normal. as long as you never get a big bulge, then dont worry about it.
