I just sent some PM's I am in Toronto

I know the 19's are worth more but I would still swap mint 17's for my 19's that have 2 small rashes but no discoloration like the way the older ones go.

glad to hear support for the smaller wheels - I don't know much about performance wheels and rubber but the average slammed honda has a way bigger proportion of wheel to tire sidewall than a Formula 1 car but then again maybe a rules thing...

I guess the theory is you get less rubber "roll over" in high speed corning with a lower sidewall/ bigger wheel but I also thought thats kind of how tires work - anyway, just a little off topic...
You can't compare a $7000 race tire to a street tire. The reason why the sidewalls on the race tires are so big is so the tire has some flex and does not lose grip due to the lateral Gs that are being exerted on it. I'm not a rocket surgeon, but that is my understanding of it. Many people believe that the less sidewall they have the more performance they get out of a car, which, at the limit, is rarely true, even for a street car.

I'll take my 18's over 19's

I agree with the point the original poster made, but for a couple basic reasons.

Larger wheels mean shorter sidewalls, thus less sidewall flex and better handling/cornering. Smaller wheels equals more rubber between you and the road, thus better resiliency to potholes, etc.

BUT, there's another point to realize as well... Moment of Inertia.

As more metal is farther out from the center of the tire, the more force it takes to turn it, thus you lose speed and acceleration.


My next Physics class is next week, at the same time. I expect to be there.

Pretty much agree. I have never been in the 'big wheel' camp. When I had my tubby, everyone was on 18" +, whereas I imported some racing hart 16" wheels, and the difference was astounding. Not keen at all on the look of big wheels either, especially as the bigger you get, the more people feel the need to get even bigger, hence those ridiculous looking cars with utterly oversize wheels. It's getting to the point where if you want to be unique, you have the msaller size, rather than huge chrome jobbies that look atrocious. Happy with my stock wheels, thankyou very much. I'd rather spend any money on other stuff, like brakes, or what have you. 95% of these wheels are no better, or worse than stock.

the F1 case (I assume is your $7000 tire comment?) I know sidewall is a function suspension - they need to cut all the turtles on those chicanes which is really hard on the car, they get air all the time

when I got my performance license I had 2 time altantic champ and he always said "da squeeling tire is da happy tire" (in a french accent) - of course its a nice even low squeel we are talking about

an old track rat I know (very good shoe) would take a bingo dabber and dab basically the area where the sidewall meets the tread when he came off a session the goal was to have all of the side tread wearing at the bingo marker - he would adjust tire pressure accordingly.

I don't pretend to understand all of the dynamic's at play - I think the wildest example of how sidewalls work is in drag racing - that sidewall looks like a toilet flushing - they must be getting 30% more tire surface area on the track

good times

by the way I am so happy to hear so many people that prefer smaller wheel fitment it speaks to the true driving enthusiats that frequent here

if you want to jam 20's on a G - go for it, you like that ride and I'll never be judgy about it, but its not for me

when I started this thread I was preparring to start the eye rolling waiting to get slammed but it never happened

its as personal as color choice

I prefer 17's too, although for different reasons.

Smaller rims usually = lighter rims = more mpg, more performance.

Also, you have far more tire selection with 18" and smaller rims.

Well, I'm not building a performance car, so I don't care about how much better 17's are. More MPG's is nice, though.
