20x11 Wheel Offset - Advice Needed

[Loco38SUP]

I'm unsure if this is a troll question, but in case it's not, the general consensus amongst people with fast cars is more tire sidewall = more grip, especially in a straight line. But even autocrossers and circuit people drop from 19s to 18s. There's tons of science behind this. Suffice to say, assuming identical tire compounds, inflation pressure, rolling diameter, tire width, ambient/road temps, road surface, suspension set up, etc, an 18in setup is going to outgrip a 20in setup all day. Our A90s can make almost any street compound 19in tire set up break free from a dig, even low speed rolling launches can make traction control kick on, I can hardly imagine the ice skating nightmare going to 20s would be.

I agree with some of your statements here but in the one above you mentioned that 20s have zero grip. That simply isn’t true.

You can get 20’s the with the same sidewall as the stock tires. For example a 275/35r20 has the same side wall as the stock rear 275/35r19 but with a bigger circumference. This leads to a longer contact patch and more forward traction.

Now if you jump to a 285/35r20 this contact patch is longer and wider. A longer wider patch will improve both forward and lateral traction.

All I’m saying is lets not generalize but rather provide useful info. for future members
