I have been thinking about get light wight rim, or get some 18". I just want to know if you save gas, and help the engine out for the long run? Really i just want to know what kind of rim will save my pocket, and car.

 

wight?

 

I was hoping going for 16" and the lowest wight you can get for a rim.

 

16s look silly on a tC. Stay with 17s or 18s.
I have 18s and only notice a slight decrease of 10-15 miles (if that much) less than the stock 17s on a full tank.

 

What about if i get 17" that have the lowest wight? Would that help.

 

Sure, that will help. A good place to start is the Enkei website. They have nice, lightweight styles for a decent price. If $$$ isn't a problem, then check out some Gram Lights or VOLKS.

 

Yes you will get SLIGHTLY better gas mileage.

BUT...
Something to consider. If getting a light weight rim gives you 1 MPG. You will gain 14 miles on a tank of gas. So you arent even saving a gallon of gas on a tank. So say you saving $2.00 on a fill up.
Average person fills up once a week. So you are saving $8 a month.
Now look at how expensive lite weight wheels are. Your gonna pay probably $400-$500 more for a TRUE lite weight wheel over a normal wheel. (and probably not be happy with the looks)

That means the to make the savings worth it, will take YEARS!!!

So just get what you like visually!!!!

 

cant go wrong with gramlights, there good looking rims, you don't have to worry about the size, there cheap and of course they're light.

 

Thanks for advice on rims and what will come out of it. Every penny help out in other ways, like getting my self a $.99 Double Chess burger from Wendy's .

 

double chess burger thats now thats funny

we all know you meant cheese

 

Need some t&a action

 

seriously, there are not cost effective measures to to increasing fuel economy.

the only ones that work accelerating leisurly, keep your tires properly inflated and maintained, don't drive around with excess weight in the car, and keep the vehicle well maintained.

other than that, there is nothing you can do. non of those stupid turbonators or gas magnets work, so don't waste your time and money on them.

you get light weight wheels to reduce unsprung weight and parasitic powerloss due to rotational mass, not for fuel efficency.
