Slight bounce when low speed. Thoughts?

[Beachcomber72]

Yeah… I was just going to suggest a tire rebalance and rotation. Also, it is possible you could have a wheel that is not perfectly round, too. But less likely I would think. Other thought would be if you have lug centric wheels and aren’t using the appropriate ring spacer. Not sure though. ?‍

Exactly what I couldn’t think of. You might have nailed it with the hub centric idea. That’s why I summoned the better minds.

I’ll start with lowering the tire pressure and see what that does and then from there I’ll move into getting them rebalanced. I just rotated them two days ago thinking if it was a tire it would move from the front to the back but it’s still up front. Do you think an alignment would do anything for it?

Never hurts to check. I’d work my way through it from least to most expensive, though. A lot of times, it can be the simplest, cheapest things that cause it.

Now your speaking a different language to me lol! I have no idea what hub centric is. I don’t have spacers on the wheels. Rims are a 0 offset 8.5.

What’s the lowest psi I should go for topical road driving conditions before ruling that out?

I just had to scroll back up to check what tires you were running. 34 psi on E rated… I’d drop to 30 and see if that feels any different. E rated tires can feel stiff depending on the brand. ?

Hub centric wheels or vice versa hub centric rings designed for larger opening wheel hub centers are there to properly center the rim in a true centered rotational function. If that makes sense. But also there are lug centric variations too. If either of these mentioned are possibly the issue.

Like @TheBirdie72 stated start with the easiest thing and work up from there.

I appreciate your help! I’m just about ready to slap one of these emblems on it and call it a day lol!

LOL …definitely more eye catching than mine! ?

Often, tires that sit overnight will flat spot the carcass. When driving the first time of the day, the tire can really bounce, depending on the construction. Once you drive for an extended time and the tire warms up, they run smooth. Cold weather exacerbates it.

Maybe this is your problem?

While greatly possible, that would be some serious crappy compound tires. Only tires I ever recall having that specific issue were the first generation milestars. Heck even our lifted golf cart with Kenda tires don’t do that and it’ sits for weeks with no use with a ton of weight on them. But once again, I know it happens.

A bounce would typically be due to something wheel and tire related. Alignments typically help with steering feel and even tire wear.

I'm a big fan of KMC's XD series wheels. I've had their XD138 Brutes for over 60k miles now. The one downside is that they are only lug centric and require hub centric rings. I don't know if they were supplied by KMC or the tire shop, but after several rotations, the nylon spacer rings were starting to loosen just enough to cause a similar feel on my front end. Only difference is that I was feeling it mostly in the 45-55mph range.

Research led me to finding out that nylon rings are great for extreme temperature environments, but they only hold dimension for so many rotations due to having a heavier and larger wheel and tire getting dragged on and off of them. I found a set of aluminum rings that are supposed to hold dimension longer.

They smoothed out my front end. I still haven't gotten around to swapping the rear rings, but will do that on my next rotation.

These are Metric 121 E Loads, so they’re rated at 80 psi instead of the standard 65 you’ll see in say a 35x12.50. Normally means you’ll run a little higher.

Doesn’t hurt to drop to rule out pressure, hell go to 25 and see if that fixes it. Short term testing isn’t going to hurt anything.

No change from a spring and shock change really rules out suspension. Alignment would be toe, which wouldn’t change but that’s more steering feel.

Those “E” tires aren’t known for a great ride-they’re designed for a load. I’d try lowering the pressure. If it still bounces ck balance. Good luck.

You are tightening in a star pattern then torqueing in a star pattern right? Not going to completely eliminate the potential for being off center but helps without rings.
