With 225/40-18 tires they will be just about perfect.snowboardin58 said:I am debating whether or not to get 18X8 42mm offset or not. Will these fit on a 2-door Viggen with stock suspension? And how will they look..stick out too far?? They are the MSR 044 wheel. Perhaps I would be better off with a 17" wheel though..less weight further out on the wheel. A larger diameter wheel will generally make the car slower, even if it is the same weight, because the weight is further from the center, correct? http://msrwheels.com/auto_car_wheels.cfm?id=282
Yea I learned about that stuff in physics..and kind of on my own when spinning on an axis and sticking my arms out and then in, ect.99Saabnut said:Try looking at O.Z. Ultraleggera 18X8s. They only weigh 18 LBs each. You still are pushing the weight out further in the diameter (18) but they are far lighter to begin with.
17s will generally accelerate/decelerate faster because the weight is closer to the center. Closer to the center means spin up/spin down faster. while 18s will handle better due to less tire deflection under load. To feel the effect yourself try doing this:
-Get a length of sturdy rope. First tie a 2 Lb weight on one end. Hold the rope about 2 feet up from the weight and try to get it spinning in a solid circle. Next do the same thing but do it with about 6 feet of rope instead of 2.:cheesy:
None of this is exact science of course; as an 18 Lb 18 inch rim will still do everything better than a 28 Lb 17 inch rim... Less overall weight by that far means less unsprung weight to get moving
I was just trying to answer your question...snowboardin58 said:I'm not sure if this is right, but 18" vs 17", with the overall weight being the same to both, the 18's would be a little better for acceleration/deceleration?? My logic is that the tire weighs nearly what the wheel weighs, but in a smaller area, and on the outside of the circle. Am I right, or would the 17" be better? Its either the 25pounds shipped...probably around 18-20pounds per wheel...MSR 044, or the Borbet type FS. Thanks
Oh ha I understand, I wasn't trying to be snappy or anything.99Saabnut said:I was just trying to answer your question...
