Highway bounce

OP, the secret to getting a good balance, assuming the tires are not defective, is you must mimic as closely as possible the way the wheel/tire sits on the balance machine as to how it sits on the truck. The principal issue is the wheel will go slightly askew on their mounting cone.

@muddog321 nailed it in post #17 above. I've posted this many times before but here it is again at the bottom of this post. Look for a shop who has the Haweka adapter, and actually knows how to use the road force machine. The adapter is used with the wheel/tire combo on the machine. I bolded and underlined the text because around here the road force machine takes special training and the tire techs tend to avoid the thing, or worse they fake it, so its the dustiest piece of equipment in the shop.

Alternatively call around and find a place that has the new Hunter Road Force Elite. It is significantly more user friendly to techs with minimal training, but again one must use adapter along with it at the time it is spun on the machine.

Ok should if I can get a good tire with a rim package should I stay same size tire?
Also highway,all terrain,cross over?

 

I got the video finally. Doesn't show ton, I can't zoom out any more.

I've seen some really good reviews on these tires. 4.5 almost all of them.
Wanna make sure I'm fixing the right thing before I drop 800$ or so

 

Ive never heard of this

OP sounds like the tires may be separating at highway speed. Rotate the tires front to rear and see if anything changes

I don't really believe the hype in Road Force balancing. I've got 275 LTs balanced the lazy way with sticky weights on the inside edge only (static balance) and my truck rides smooth as glass. In my experience an out of balance tire will cause the whole cab to shake not just the steering wheel

 

Well the tires in front are much better than the ones in the back I am due for tires really soon going to need to get them before October that is when my sticker is due

 

8 year old truck w 80K miles on the suspension and suspect tires AND the steelies??

I go to Town Fair Tire. ( They were the only one around me that could mount 315s for my Shelby.)

They’ve been good but not terrific for me w my Tacomas. I typically get the Michelin LTX M/Ss all around. Several times I needed to go back to have them rebalanced on both my ‘07 OR with the alloy wheels and my ‘15 with the steelies. Eventually they get then zeroed in but I plan on it being a PITA every time I get new tires.

I wouldn’t go w one of their packaged tire/wheel combos. Get yourself a take off set or go with one of the vendors here for your wheel needs. Delay the purchase if you need to or just make sure TFT sells you a known name wheel with a good reputation. You don’t want to end up with the ‘Eldorado’ of rims...

Good luck

 

I had this issue once. It was due to a bent rim. Even after the tire shop balanced them, I could still feel it at highway speed.

 

I know what you are saying. A long time ago I had an old jeep with mismatched tires and simply could not afford to balance. For some reason it never had vibration issues. The Taco I have though is a different animal and problematic even with three different sets of new tires now. The only way I can get the steering wheel to settle down and keep from driving me crazy is a meticulous balance on the RF machine using the adapter. I now have smooth-as-glass rides but what a pain.

 

Ding ding ding

Using the adapter FTW

 

We just mounted four brand new Firestone Destination A/T's P245-75-R16 on stock off road rims and static balanced, with stick on weights on the inside of the rim. No vibration at any speed up to 65 mph and very little weight required. We also just mounted 4 new General P205-55-R16 on a VW Jetta. We peeled off A LOT of old stick on weights and static balanced only again with very little weight required. No issues at any speed so far. I don't doubt that dynamic balance is better and road force may be best in some cases but I think often worn, damaged or poorly manufactured (at any price) tires are at fault. The other big one is poor quality balance work at the shop level ( weight chasing, dirty rims, failure to remove existing stick on weights, labels, pebbles in treads ect.) Of course this is based on the assumption that the rest of the suspension is not worn out, that the rims are not bent and properly centered with the correct lugs and the tires are close to stock sizes.

 

That makes ZERO sense for all 4wd double cabs to be prone to tire shake especially if its DCSB since it is the same truck as the access cab.

Not sure what tires you are referring too but if talking about El Dorado those are not even a name brand tire in my opinion. Look for Goodyear, Michelin, BF Goodrich, Nitto, Toyo, Yokohama, etc.

 

What tire pressure are you running or did I miss that?

 

Damn, I need to go out to the garage and take a few tape on wheel weights off so mine shouldn't ride so smooth going 90mph on the highway. Sorry but I don't buy this unproven statement. OP, speed sensitive vibes are usually always tire/wheel balancing related issues, not suspension. You need new good quality tires installed, balanced, and alignment done at a reputable shop to fix your issue.

 

Its hard to tell for certain what parts are causing your condition. I can say for sure that if you drive long enough with the vibration, other parts will start to wear at an accelerated speed as well.
