Hello everyone;
I'm looking to upgrade my rims/tires but I'm not sure about the sizes...I already have my eyes set on the 18 inch Konig oversteer. And i imagine the tires would have to have lower profile since the rims would be bigger. Also if I wanted wider wheels, what would I have to look for size-wise...thanks in advance

This is the wheel calculator I use: https://www.rimsntires.com/specspro.jsp

Assuming the stock 17 X 7 wheels have an offset of 45 with a tire size 215 X 55 17 (Touring)

An 18 X 8 48 wheel with 235 X 45 18 tires would have the same diameter (+ 1mm). This setup would be 0.5" closer to the suspension and 0.3" farther out which should not create a clearness issue. At 60 mph for the stock set up, it would be faster at 60.1 mph.

This combination would look the same in the wheel well and provide a 1" wider contact patch while not effect the speedometer reading very much.
