Um, is that supposed to be good looking? It looks like you either rolled your fenders with a crowbar, or those ill-fitting rims rolled them for you.....

 

I was about to say the same thing.

the rear looks like the fender wrapped around the wheel, and also messed up the line/crease that goes from the front fender, across the doors, and to the rear headlight.

i had 19's on a stock setup on a 99 civic and i had no problems

 

In what circumstances is this important? If you are cruising down a straight, flat road then you may have 16 extra pounds of vertical load giving you traction, but if you are cornering on anything other than a perfectly flat surface, the extra weight of a 30 lb wheel will be much less willing to move over a bumpy surface and lose traction when compared to a light-weight wheel that will easily move in response to an uneven road surface.

Yes, the tires provide a certain amount of spring that isolates vibration from the cabin that gets reduced with a smaller aspect ratio, but a heavier wheel will again be much less willing to move over a bumpy surface and less movement of the wheels means less movement in the cabin, superior ride quality.

How do the importances of sidewall or unsprung weight compare to eachother in the end effect of ride quality I cannot say...

I believe that if the bumps are the same height, they will move the wheel up or down the same displacement regardless of the width of the wheel.

I don't think the bed of nails analogy fits correctly here, I know that the weight will be spread out over all of the nails instead of just one, but in the situation of riding over a bump, a rise in the road will cause a force upward on a constant section of the tire ( the width of the bump ), no matter how wide the tire is. In the bed of nails analogy, the surface area of the bump (amount of nails) is changing, where in the bump in the road analogy, its the size of the person sitting on the nails. The guy will still get punctured, even if hes huge.

Perhaps if you are riding a wide enough tire, the ride quality may improve when you go over a hole in the ground as apposed to a bump. If the tire is wide enough, the sides may be able to hold the entire wheel from going down in the hole.

 

I was being sarcastic.

You are absolutely nuts if you think ride quality will improve going from a stock 16" (or even 17") S2000 wheel to a 19" wheel (much less a 20"). I'm sorry, but you saying the tires provide a "certain amount" of spring that isolates vibration... is kind of like me saying that the engine provides a "certain amount" of forward propulsion to a vehicle. Give the tire some more credit.

Why do you think luxury automakers known for their cushy rides (like Lexus, Cadillac, Buick, etc.) always use wheel and tire combinations with large sidewalls? All things being equal, less tire always means harsher ride.

 

I need to put a warning on this thread...

 

lol. that car was on ebay go 30k. 1 bidder at the time.

 

And that has what to do with putting 19's on an S2K?

Should have known you were a Civic boy

 

My old setup. They were 19" forged aluminum and weighed the same as the stock wheel/tire combo. The car is my daily driver and I liked driving on them a lot.
