So got a new set of wheels and tires. 3 piece rims. Running 225/35/19 up front 245/35/19. Cheap Achilles tires. Been having all sorts of balancing vibration issues since I first mounted these new wheels and tires. To this date in the past month or so have had them balanced 3 times. Each time they find more areas for improvement. Never fixes all the vibrations. Noticed I'm getting vibrations not just in my steering wheel, but throughout my car. Can even feel the shifter vibrating. Also going down hill, foot off the gas pedal, coasting in drive, I feel it more. As I've read throughout the forum, I went to get a road force tire balance. They inspected my tires and determined the rear tires did not meet the OEM specificatons of 95 lb/fts of force at only 93. With that said they would not do a road force test on the rear but did do the front and say it's good to go. Tires are good and rims are true. They also tell me if I'm feeling vibration throughout the car it's coming fron the rear. So my question is, does anyone know if this is true? My previous set of wheels I've never had this problem. They're recommending I step up my rear tires to at least a 255 and that'll bring it up to OEM specs of 95 ft/lbs. I'm so incredibly frustrated...

BTW bought brand new hub rings for them too.

Could you put stock wheels/tires back and see if it still happens?

Aspect

Did you upsize when you got new wheels? I'm thinking that's the cause of the increased vibrations since thinner side walls have less dampening. Else.. maybe check to see that your 3 piece wheel is bolted together properly?(just throwing out a random guess)

Since the only thing you've changed on the car are the wheels and tires, unless these wheels were used, I'd suspect the cheap tires are to blame here.

If the rims are "true" then buy yourself some quality tires - judging by your signature you don't seem to cheap out in other areas.. why stop short with the tires??

Deathrow23, I just got done swapping back to my old set of 19s with Hankook 235/35 and 265/30s. Rides like a dream again. No vibrations what so ever. Steering feels solid and inspiring.

Aspect, I didn't up size really, same size rims but changed the offset just barely. Not evendors enough to notice a change in appearance which wasn't my intention. Bad advise and not enough research on my part. Went from a 19x8.5 + 30 front and 19x10 ×38 rear to 19x9 +35 and 19x10 +35. I actually changed the profile on the rear tires from a 30 to a 35 but went narrower for more stretch and clearance.

Gville, these are brandspanking new Wed Kranze LXZs I waited for 3 months to get from Japan. As both yourself and SeanO have pointed out, these tires are cheap. I probably shouldn't have skimped out on some quality rubber but I've actally had this exact same set before in a even narrower profile of 215/35 and 245/35 on my old rims. I never noticed a difference in ride like this set I have today, that's why I didn't hesitate to take advantage of bargain rubber, especially how we go through tires with camber etc. I suppose now I've learned my lesson. This weekend I'll take my weds into the shop and have them mountil my old Hankooks off of my old rims and make sure I'm getting the same feedback on the weds as I am with my old rims. If all is good I'll upgrade to some better tires in a couple months. Going to have to sell these tires aND recoup some funds from all the shenanigans I've been going thru trying to zero in the problems I've been having. My Hankooks had cost more than twice what I paid for these Accelera tires.. oh and I made a mistake on the brand. Not achilles, accelera.

While inspecting the two different tires I noticed the Hankooks are far superior in build quality than the acellera brand tires are. Hankook tread plies 2 steel, 2 polyester, 2 nylon sidewall 2 polyester.
Acellera tread plies 1 polyester, 2 steel, 1 nylon sidewall 1 polyester.

A friend of mine is running toyo proxes sport in the same size as I am. Says tread 2 steel, 1 rayon, 1 nylon sidewall 2 rayon. Rayon same as polyester? He says he's happy with them.

I had Toyo Proxes on my 08 before I traded it in.. They were a great tire.. I tried to get them again but they didn't have the rear tire size that I wanted so I had to go with Michelin Pilot Sports

I was running 235/35/19's all around on my AWD setup with the toyo's

If you want a budget-friendly tire, look at the Federal EVO 595s. Been very surprised by the performance they offer AND the 240 treadwear they advertise is low. I'd say it's more a 300.
