Absolutely
I am just trying to show that a lot of the posts are based on outdated opinon
I said nothing about 15" tires on a Kappa. I said CAR tire, not KAPPA tire, but I'll try to be a bit more explicit next time so the hard of understanding can keep up.
So now Kappa's aren't cars?

Your thought process is stalled in the 1960's
[and your high opinion of what you think is incorrect about all modern vehicles that don't fit your optimal mold for a car]
Emissions, Safety standards, increased engine performance, increased braking, increased handling and passenger comforts have evolved past your level of thinking. These new technologies [And REQUIREMENTS] have resulted in heavier vehicles. These heavier vehicles require a certain size tire to support the weight and at the same time have comfortable and safe handling.
15-16" tires will not work on most vehicles, but 17-18" are needed. I will admit 20" "AFTER MARKET" wheels are mostly chosen for visuals, but the purchaser of those are free to spend their money as is.
What's absolutely hilarious, is this current argument of yours completely contradicts your previous statement about how important good tires are.
Larger diameter tires can support a wider surface area, with a sidewall ratio that leads to increased handling and braking with adequate sidewall stiffness.
You are all over the place and floundering at this point.
Just give up.
Modern engineering has eclipsed your narrow viewpoint of what is necessary on a car.
