Will they fit? 15" Konig Theory

[BUSTIVA]

You may need a small spacer, I put on a 7in wide +40 offest on my car and it required a 1/2 spacer if I can remember correctly.

But as for tires 185/45 or 195/45 is really the only I would run. I had 195/50s on my car and they looked huge, couldn't imagine 250/50s lol.

Pic in my sig are 195/50s

Further, the main issue for fuel economy junkies is unsprung weight - that is, weight not supported by the springs of the car. Supposedly, it is said that sprung weight has a multiplier effect of 4x when changing speed... meaning that reducing your wheel/tire/brake/etc weight by 10lbs would have the impact of 40lbs when zipping around town, which is considerable. It's also a popular reason not to opt for the Aspire swap, as many people feel the weight increase of larger rotors could harm economy.

Very good explanation, all I would add is that you are actually talking about rotating mass, not unsprung weight in general (though at each corner the rotating mass is unsprung as well).

Guys... You do realize that this is my 7th Festiva, (Not to mention the 3 aspires I had either) I've had stockers, I've had a B6T, I know the Festiva road pretty well... I just have never tried to cram a 15" rim on the Festiva. Also, I understand how sprung/unsprung works, I just can't imagine that a 20% difference is going to happen.

I have 195/45/r14s on my festy with no rubbin no spacers all around yezzir

They will rub with the car stock, but with some fender massaging and spacers in the rear, they can be made to fit without rubbing. I have 15x7" rims on my car. Also, federal tires sells a 165/45/15. They can be purchased for around 60 dollars a tire. I just bought a set and they look like really good tires, but I haven't mounted them yet. I'm putting them on my 15x6 rims. With these tires you may be able to just bolt the wheels on and go, since they are very close to the stock outer diameter. This tire with a lightweight 15" rim will be lighter than the stock wheel/tire combo.

Where did you buy them?

^^ X2, I may put the old 15s off of my brother's MX3 on FestEvil if I can find skinny 15s that cheap!

Here are your tire choices from Tire Rack in a 175/55-15 size:

http://www.tirerack.com/tires/TireSearchResults.jsp?width=175%2F&ratio=55&diameter=15

These will give you about the same diameter as the 175/70-13 or 185/60-14 or 195/50-15, but the 175mm width should be almost as forgiving as the 165 width.

The three regular weather tires' weights shown run from 15 to 16 pounds each, which aren't bad at all.

Yeah, but the cheapest there is $76, which makes for a $64 difference on a set of four.
