Did I screw up?

[campoo]

Currently own a 3.3t AWD G70 and recently bought new rims and tires. I might be a dumb teenager but recently noticed stutters when making low speed turns and was wondering if my tire/rim setup has something to do with it...

Heres the setup:


Feel free to be brutally honest and if anyone can drop some suggestions please do!

Should be just fine, something else during the install may be coming into play, but the tire & wheel specs look just fine, they did put the wider tires in back correct?

Yeah they did put the wider ones in the back. I just recently saw someone say 19 inch rims will cause vibrations when driving at high speeds. Of course there also could be numerous other reasons for that. Already booked a diagnosis at Hyundai (dont have a stand alone Genesis Dealership near me).

If the wheels/tires weren't road force balanced I would have them do that or find a shop that has one. 19" wheel/tire setup shouldn't have any problems assuming the tires and wheels are running true. Might have had some wheel weights fall off or a tire technician that messed up, it happens.

Two other things that needs to be mentioned, you have aftermarket wheels that will have a larger hub bore, if you don't have hub adapter rings I would definitely get some. The Genesis has a 67.1mm bore, and your Niche wheels will have a larger bore 72.56 mm is what's listed on their site. So these hub rings are what you'd need, this can reduce or eliminate high speed vibration in many cases.

I use hub adapter rings in all my aftermarket wheel sets that didn't have a custom vehicle specific bore, and have never had any vibration issues.
Also I'm sure you're aware but just in case, those wheels require conical seat lug nuts, so hopefully you have the proper set w/ your new wheels
hope that helps!

Okay sick man, I found these ones as the link you sent cant be shipped to my
country Would these work? https://www.google.com/aclk?sa=L&ai...CNAxUGNzQIHRAPBywQwg8oAHoECAUQEQ&nis=8&adurl=

Those would work, I prefer aluminum ones as they last longer, but the poly ones will be fine if you don't get too rough with them during the install and w/ rotations.

Whoever sold you the wheels and tires didn't include hubcentric rings? Or at least advise you that the rings are needed?

Plastic hubcentric rings work just fine for street duty but will get cooked at the track, when brakes get hot. Aluminum ones cost a little bit extra and last a long time. That said, aluminum rings do tend to get stuck to the hub from galvanic reaction, so make sure you paint it with anti-seize before mounting them on the wheel hub. Plastic ones don't have this problem.

This kinda makes me think it has something to do with your AWD not liking the new tire/wheel sizing. The numbers look okay, but you just never know. If the effective rolling diameter between front and rear vary too much, the AWD won't like it and will make noise.

Found out today by checking that yes they included hun rings haha! I bought the car used and the last owner had the stock rims with the same tire specs and the noise was there before... If you dont mind, how could I check the effective rolling diameter? Thank you very much for the help

Most direct method is to put a mark on a tire pointing straight down towards the ground. Draw a mark on the ground that lines up with that mark on the tire. Then, roll the car slowly forward, or backward whichever is more convenient, until the same mark is pointing straight down again. Draw a line on the ground that lines up with the mark on tire. Now measure the distance between the two marks on the ground. That is the rolling diameter.

Do make sure you have the correct tire pressure, or the measurement might be off.
