i went with 245 front/275 rear since the 265 rears were backordered. that said, i was already lowered on tanabe springs with 15mm/20mm spacers. i dont recall seeing that combo on here...do you guys think i could potentially have issues with the change in tire size?

I'm assuming you are on the stock 19's? I'm running 245 and 275 on 20in wheels and started experiencing rubbing issues in the back. Had my wheel shop roll the rear fenders and that fixed my problem.

This isn't just a nuisance vibration; its significant enough to shake the water bottles in the cup holder and I can see my empty passenger seat shaking. I can't isolate where exactly its coming from as its in the rear and in the front. Looking for some additional troubleshooting ideas. I'll give you the run down on what I've done so far.


I first noticed the vibration was there when I bought the car but didn't really sweat it as the car needed new tires anyway. I'm still on stock wheels and suspension at this point. So I have new Continental DWS06 tires installed at discount tire (mounted and balanced). I noticed the vibration is still there from 70-80mph. Multiple trips to different Discount tire shops (8 visits) to have them balance and road force balance with no luck. The second road force balance test did reveal one of the continentals had a slight bump in the tire. So we replaced them with a set of Michelin Primacy tires. Again vibration is still there at highway speeds. The manager of discount tire is determined that I'm imagining things and insist that he personally balance and road force check them to prove me wrong. I won that round but that still doesn't fix my issue. At this point I'm thinking its the wheels so I bought a new set of wheels and while I'm at it I lowered the car on Tanabe springs. Had the wheels balanced and once again...vibration is still the same. We noticed I didn't have any hub centric rings installed on any of the wheels so I ordered them for both sets of wheels thinking that would surely be the problem. I ended up getting another set of wheels just for a backup set with new Continental DWS06's this time with the rings installed...again vibration is still there. I just had the alignment done as well...surely this will fix the problem....no luck either. I thought...maybe the front rotors are warped; but shot that idea down as my car doesn't shake under braking but I had the rotors resurfaced anyways as the brake pads where grabbing part of the rotor when I spun them. That didn't fix the vibration either. I checked both tie-rods and all wheel bearings and everything is tight.


The car currently has 58K miles (majority being highway miles). I have an appointment scheduled in the morning with Lexus; but I have a pretty good feeling they will blame it on the lowering springs and the aftermarket wheels.


I ordered the SPC rear camber kit and will be adding that as well as getting my alignment accomplished again. I'm thinking coilovers to swap out my shocks as I think they will need to be replaced soon and re-surface the rear rotors; but I'm not sure that will solve my problem.


Any ideas of what I could try next would be greatly appreciated!
