2018 Kia stinger GT2 tire scraping issue

[Albeeda1]

Hello fellow Kia crew
Question amongst the owner’s . I have a 2018 kia stinger Gt2 last year I purchased some 20 inch niche wheels from one of our vendors with tires fronts 245/35/20 bf Goodrich and rears 285/35/20 style and wheel looks nice and I hardly drive the car but lately I been getting up on the pedal if I hit a hard corner or a bump the rear tire scapes not the inner fender well but the outer bumper cover edges does anyone the proper size I will need for the rear tires not to rub & scrape anymore ?

Welcome. You should get a response, but you’ll get more responses if you post in the proper section and use a title that’ll attract people who can assist with your specific issue.

edit: I moved the topic and updated the title.

Howdy and welcome. You left out the most important factor, offset. And your description is tangled. What is "rear tire scapes not the inner fender well but the outer bumper cover edges", describing? I've never heard of any tire tangling with the bumper covers!? Those size tires should not pose any problems.

But, looking at these hypothetical changes on this calculator, it looks like you would gain clearance and a better sidewall match if you went with an aspect ratio of 30 in the rear instead of 35. Here are the two comparisons with OEM (offset is left the same; and I am assuming that you went at least half an inch wider on the wheels in front and an inch wider in the rear):

Most definitely not the inner fenders. I am having issue with the rear tires rubbing on the rear edges of the rear bumber cover only when i hit a big dip or hard turn when the car sways etc.. i have had to push the rear bumper cover back on its clips only along the edges above the wheel well . If you are referring to the Niche wheel offset i will call the vendor tommorow to verify what exactly the Rim specs. Tire shops have suggested me Going down to a 285/30/20 tire.

Tire shops have suggested me Going down to a 285/30/20 tire.

And the calculator I showed says as much. That should fix your rubbing issue (which I still cannot visualize from your description, but of course accept that you are experiencing rubbing, a bad thing!).

What are the sizes of the rims AND their offsets?
