choices, choices. I have been contemplating switching back to my stock 16x7 wheels and running a spacer. My reason for this is that they are lighter then the steel wheel and sometimes but not all the time I get a small amount of steering wheel shake as I drive. I have had my tires rebalanced and it did not correct this. But really it isn't too bad most of the time. I still have some time before I need new tires but I have decided on General Grabber AT2, so here are my choices. 1 - I stick with the steel 15" rim and get the 31x10.5 they are 39pds and measure 30.8 in dia. 2 - Go stock 16" with 245x75 they are 44 pds and measure 30.5 dia. 3 - stock with 265x70 they are 41.6 and measure 30.6 in dia. 1 seems like the best option lighter and taller but I may consider option 2 to run the lighter aluminum but it seems like I am going to even out unless the steel wheels are that much more heavy then the stocker. And I am on the fence about option 3 what would you do, FWIW I got this info off their website. |

Hi im a tire tech and what you are saying kinda sounds like your tires might be cupping or just were not rotated at the right time. |

Ditto, the increase (or decrease) of weight with your tire/wheel combo alone will not cause shaking or shimmying. Bad balance, Cupped/poorly worn tires, balloints, or bearings maybe. |

tires are good, ball joints are good, bearings good. This has happened since I got the steel wheels. May be a bad balance but I have had that done..twice. Like I said it isn't really a bother. I just don't know what I should do tire combo wise. I just found out the 245x75 are and E rated tire and I don't want that. so I am either going to stick witht the steel 15" or swap back to stock and run 265x70 or maybe a 75 not sure sure if I want to go that big. Thanks |

A much heavier tire & well combo can exagerate the problems he is describing. I just switched to some street biased p265/70/16's over the e-rated 245/75/16's and noticed an improvement. I did not weigh them but I would put the weight difference between each set at close to 10#'s a corner. |

I have been paying a little attention while on the road and i noticed that at the same changes in the road during my morning route the steering wheel starts to shimmy a tad but on smoother roads it is perfectly still. I just think that the steel wheel you can just feel the road changes more and with the alloy. may also have a bit to do with the tire combo. That being said I am going to stick with the steelie, they just look sexy on the jeep and I want to "tallest" tire I can safely fit on it. |

Have you had the balance checked with no weights to see where they are out of balance? Maybe they can figure out where it's out, mark tires/rims, then dismount and move tire on rim. I've seen this help cure balance issues that cause vibrations. I get wierd shimmies on my Tahoe from the front, not all the time or at specific speeds. All were balance, but I get it from time to time. |

Dirk at DPG Off-Road told me that many steel wheels are bad from the factory. From his experience, 1 out 4 Cragar Soft 8’s will not balance out. For this reason, he now has a cheaper 15” aluminum wheel that he recommends. |
