Hoping to get advice from some experts on here.
Brand new summer wheels and tires for a new Genesis with only 2000+ kms.
Tire is Uniroyal Tiger Paw Touring A/S. 265/40/21.
Tires ordered online from big online retailer in BC, wheels from one of two distributors here in Canada, and tires were installed at by a local shop that has a Hunter Road Force balancer. That was a must.
Got home last night, removed my winter wheels and tires, and installed these brand new 21" wheels with new tires. Wheels are Rotary Flow forged, custom bore so hub centric, custom offset, so pretty decent quality. Over $800 a pop.
Issue:
First drive after putting them on - very slight drone noticeable about 55 kms per hour which increases in frequency faster I go. Lessens for a bit and starts to get much louder as I hit 80-85 kms/hr and up from there. Noticed once, that upon deceleration, also got louder, but have not driven enough to try this again at various speeds. Also have vibrations at around 70, and over 110. Mostly in the body, not really noticeable in steering wheel, which suggests vibration issue stems from either or both rear wheels. So question is whether the vibration is tied to the drone, or separate (ie. issue with tire is causing both, or tire is causing drone due to defect and wheel is slightly out of balance)
The shop that installed said they would have a look, so I will be going back in the next few days when I can. Retailer recommends having it looked at by a mechanic...they are, and point me to warranty form online if they find an issue with tires. Suggestion is that it could be defective tire.
Anyone have any experience with this issue, thoughts on potential causes if a mechanical issue or tire issue, and if tire, what defect in the tire could cause this drone issue?
Any feedback or guidance would be appreciated.
thx.
