We purchased a certified used Honda Odyssey with about 20k miles on it. From the start the tires caused the van to pull and act like it was out of alignment. Rotating the tires alleviated this problem, but there was still some shuddering/shaking. I purchased new tires and the shudder and shaking is still present. When I took it to the dealer they claim the tires (Falken SINCERA SN250 A/S) I purchased were just cheap tires and causing the shuddering and shaking. They did a $100 road force balance which maybe helped some, but there is still noticeable vibration when driving.
I haven’t been able to pin point at what certain points the vibration/shuddering is coming from. It seems like during acceleration, but also when cruising at 70 mph highway speeds. It seemed like at 65 that it was less noticeable. Aside from buying yet another new set of tires, what can be done to check out what might be causing the issue. I just rotated the tires and it doesn’t seem to have helped at all.
The van is still under warranty, but I am hesitant to take it back to the dealer since they weren’t much help in pinpointing the issue. The van had the original expensive Michelin tires on it when we purchased it and I feel like they had the same issue. Also neither the tire installers nor dealer mentioned anything about the tires/wheels being bad enough out of balance that they couldn’t get them to balance.
