Default Do bigger wheels effect engine performance?

I just bought a set of ADR 5 spoke 18" rims for my car.
Can anyone tell me if going from stock 16" to 18" rims is going to effect performance, and/or add extra stress on a Tip. Tranny.

Thanks

Default Unsprung weight is the enemy.

One of the most important considerations in choosing wheels and tires is the weight.

Default it may add more weight to farther out on the radius of the tire...

therefor having a larger moment arm blah blah, which hinders accelaration a little, but you wont have as much tire sway, and probably better handling depending on what rubber you choose

Default Short answer yes..

more energy is needed to rotate a larger mass. thus the 18's will take more to spin. IMO won't effect the performance of your car enough to notice.



Cheers,

Default Maybe not on a stockish tip car but toss a set of <14 lb wheels and light tires on your T28 and

see what you think. Might be surprised about the overall performance gains.

Default I figured that the main factor

was the overall weight of the wheel. Unfortunately I was not smart enough to check what a stock wheel weighs before I bought the ADR rims. I guess that if there's no noticeble difference in acceleration then I will keep them.

Default I went from stock 16 to 18" ADRs... I don't notice anything different, except>

rougher ride (obviously b/c of less rubber)

handles better

looks better too ;-)
