Default is this normal??

Hello guys I just installed a set of 35" mickey thompson mtz's with the mickey thompson beadlock rims and now it seems like my steering wheel shakes back and forth sometimes. Thats the odd part, it's not always consistent. Is this normal for mud tires? If not any clue as to what could cause it? I was told possibly adding a steering stabilizer would fix it?

You can get some wobble in the steering wheel from an aggressive tread, but shouldn't be much. I'd be more inclined to think either they didn't road force balance them or you got a bad tire.
Don't hear a lot about bad Mickey's out the box, but it happens to all of 'em on occasion. Of course if you just went up in tire size, could be you got a bad component exposed by the larger diameter tire. But a competent shop should have checked your tie rods and ball joints when replacing tires.

I'd still have 'em checked where you had them installed, and if they are not road force balanced and only balanced, I'd pitch a fit. Can't cut corners balancing a 35" tire...

I got them mounted and balanced at the local discount tire center and I believe they were only spin balanced? any way to tell for sure? from what I hear road force balancing is not really found around here besides tire rack.. They charged me $68.00 to mount/balance with tape weights

EDIT: I did not have the tires installed on the vehicle by them, just on the rims and did the job in my driveway to assure clearance.

A standard wheel balance (aka "static) only measures a single weight plane from top to bottom as a tire is spinning.

A road force (dynamic) balance measures for wheel variations along two planes, both top to bottom and side to side. Many of today's thicker sidewall tires (D and E rated tires especially) can have a variation in sidewall stiffness which can only be detected and corrected using this method...

LOL - I remember when spin-balancing was the "good" kind, and "bubble" balancing was the cheap way. In our service station, we only did bubble-balance because we didn't have a spin-balancer.
