:headscratch:Ok, so I see I'm not the only one have the stupid shimmy problem...... makes me want to drive my DJ in a lake a leave the stupid thing there....... but never the less, I am going to let you know it isn't a tire issue, its a wheel & tire issue.... what I have come to conclusion to, is this....... The fake chrome, well the Chrome Clad 19' wheel is a piece of junk wheel, and the 225/55x19 is a very heavy tire... Now I have contacted about 15 different Dodge shops, and here is pretty much what Ive been told by almost all of them..... Its a really bad wheel design because dirt, road grim, and brake dust can build up in side between the alloy and chrome cover over time..... best thing to do to get rid of it, get rid of them, Ive had 5 alignments done, lost count of balances ive had, I know its more than 20 or so, and about $10K worth of suspension work front to back done. Yeah Im tired of it so im going to be looking for some wheels.....oh oh oh and if your shop doesn't have the special wheel balance adapter it wont be worth it at all to get new tires because the vibration will wear a tire down faster than you would even want to imagine.... but yeah Im going to be looking at new aftermarket wheels, wish I could but some 17" Pro comp wagon wheels on my DJ but there isn't enough back spacing for it Hell who knows I might just go all Frankenstien with my DJ and cut the flares off and cut all the plastic out and jeep flare it and put the jeep wrangler front brakes on there and put some fattys on there hhahahahahaha..... Im an automotive engineer so who knows I might do it...... hope this helps
