17's look good?

Ok so I have searched the entire forums and I have found nothing that really goes with what im asking.

I found some 17" Drag DR8 rims for my pearl white 06 4-door. I did not know if 17's would look too small on my car(even though stock rims are 17)? I do not have a drop and i do not have the money right now to buy bigger tires and rims. If I could get some opinions it would be great. Basically, 17" ok or no?

Here is a pic.


Thanks

You could probably score used oem 18s w/ tires for the price of those new. Unless those are seriously cheapo wheels.

IMHO, if you don't have the $ to upgrade to 18s+, then just save your $ and run your stockers. It's a waste of time to buy another set of 17s. IMHO

too small! run the 18s...it shouldnt be that much more neways these days...
everyone is pricing up the 19s 20s staggered look...but for the sedan u can run all the same offset, non-stag 18s should be the minimum. we have a pretty big wheel well and decent size car.

^+1


u can find some in the marketplace...ebay has some decent priced rims...take a look at the picture share in the sedan section to get some inspiration and find the right offset and wheel sizes..good luck

The oem sport 17's are the style that comes all the way to the lip and they look tiny on the sedan. I can't imagine how small those would look.

I'd save up for 18s, which I think are the ideal size for the 1st gen cars if you care about ride quality, tire life, and keeping most of your acceleration in check.

As ttrank pointed out, getting rims like the ones pictured will look smaller than they really are because the spoke line ends well inside the wheel which takes away from the overall size of the rim. The OEM 17s pull the spokes to the outer edge of the rim which makes them look acceptable.

Actually The larger the rolling diameter is the better your acceleration is, they make less rotations with the same power. IE: Think if you put lawn mower wheels on a G, they would be spinning a zillion times before you moved 10 feet, and your rpms would be through the roof.

Just being technical.

There is a happy rolling diameter for every specification. I'm not saying if you put 44"s on a G that it would accelerate better than 18"s, because there is a ratio, of RD/Tq /ft-lb/Rpm

effective ratio = (old tire diameter / new tire diameter) x original ratio
actual mph = (new tire diameter / old tire diameter) x actual mph
mph = (rpm x tire diameter) / (gear ratio x 336)
rpm = (mph x gear ratio x 336) / tire daimeter
gear ratio = (rpm x tire diameter) / (mph x 336)
tire diameter = (mph x gear ratio x 336) / rpm

So like when I changed from my stocker 17s to my 20s I utilized formulas to figure what rolling diameter I need to be close to:

Orig Rolling Diameter: 26.74 in
NEW RD: 26.96 in

Orig Radius: 13.37 in
NEW RAD 13.48 in

Orig Circumference: 84.00 in
NEW CIR: 84.69 in

Orig Revolutions per Mile: 777.8
NEW REVS P/M: 771.5

When Speedometer Reads 60 mph
Actual Speed 60.5 mph
Diameter Difference: 0.82%

using
tire diameter = 2 x selection width x aspect ratio / 2540 + rim diameter
effective ratio = old tire diameter / new tire diameter x original ratio
actual mph = new tire diameter / old tire diameter x actual mph

At any rate. I think if you are asking about Looks alone... I would go bigger.
peep the thread in my sig...

Actually, it's the opposite, the larger rolling diameter, the slower you will be with the same HP.

It's all in mechanical advantage. True, larger wheels cover more distance per rev, but they also take more power to spin since their center of mass is farther away from the hub. Add to the fact larger diameter wheels are usually heavier and you are increasing the amount of work needed to spin the wheel...requiring more HP to overcome.

It's the equivalent of adding taller gearing, or stepping up to a taller (smaller sprocket on rear) gear on a bike.

Also, say you have two wheels of the exact same weight. One is a 17" wheel and one is a 20" wheel. Even with tires they are the same weight, but the 20" wheel will require more energy to spin because the area of most mass (the actual rim) is further away from the hub. The 17" wheels rim is closer, so mechanical advantage allows it to be easier to spin. it's why drag racers go with small diamter wheels. Less HP needed to spin them. You also get larger sidewalls which help absorb the shock of a launch resulting in less tire spin. Short sidewalls on low-pro tires don't flex as much, so it's easy to break them loose.

So larger wheels usually costs you speed.
