Which size tires - slow down the car
Let's justt say stock 195/55/15.
If I was to go with a 17 wheel package that that's 5% taller overall compare to wider tires (bigger footprint, like 215), which slow the car down more?
Wider will improve handling, how wide can one go before it slow down the car? Or does tall slow it down more because of more rotational mass?

Re: Which size tires - slow down the car (GoLowDrew)
Wider will not imporove handling, it will just increase your chances or rubbing. It is also best to stick to the stock overall diameter.
If your car did come with 195/55-15 stock going to 215 will probably not lead to rubbing but there are no guarentees. I would concentrate more on getting better quaility tires. That is what will improve the handling.
If you do get tire that are a bigger overall diameter that will affect your acceleration. Yes, a heavier wheel/tire with more wieght on the outside of the tire will affect you acceleration but not as much as you think. It's almost negligable. It will have ever effect your steering, handling, and suspension as it has bigger rotational inertia and is heavier. It will be like having bigger gyroscopes for wheels.

if you are worried about performance the go with a 16" wheel
stay as close to stock height as possible....205/45/16 or 205/40/17
technically a wider tire will grip better but...
in my experience it is better to spend the extra money on a stickier tire than a wider one. The rubber compound make much more of a difference than a half an inch of tread.
Goodyear Eagle F1 GS-D3 is a good choice on tirerack.com for either size
my personal favorite is the michelin pilot sport, but they don't have it in those sizes.
the bfg kdw or g-force sport is a good cheaper alternative
the Yokohama AVS ES100 is decent as well but the sharp edge design makes lateral handling not as good
you get what you pay for in grip and handling
and if you are worried about size and acceleration go with 16" and keep the height the same

Yes and no.
copy pasted from another thread
These facts seem to be important.
1) Wider tyres are more prone to aquaplaning.
2) Wider tyres are more sensitive to camber control.
3) Wider tyres on the same rims might not perform as expected, as rim width relative to tread width can have a significant effect.
4) It is virtually impossible to get a result with all other things being equal as there are a lot of variables.
It is also important that the car be set up correctly for wider tires if there is any possible advantage and under what circumstances/conditions. You don't see any rally cars driving with wide tires in the snow. So it comes back to the great compromise. Unless one wants to own about 10 different sets of tires for every condition that he/she may encounter in the morning on the way to work.
I think there is a big marketing thing onbehalf of manufacturers. The cars look meaner and better if they have wider tires. People are willing to spend more on that.
other stuff I have found:
1)Soft compound tires are required to be wider in order for the side-wall to support the weight of the car. Also to allow them to last longer. Harder tires can afford to be narrower and still last.
2)Wider tires, assuming all other factors being equal, commonly have stiffer side-walls and experience less roll. This gives better cornering performance.
3)asphalt is not a uniform surface. Even with steamrollers to flatten the asphalt, the surface is still somewhat irregular, especially over the with of a tire. Drag racers can therefore increase the probability or likelihood of making contact with the road by using a wider tire
4)I personally think wider tires allow for a bit better speed and efficiancy as the tire will not have to deform (flat spot at the bottom) as much to allow for the same contact patch area. The less deformation the less energy wasted.
And of course you usually find wider tires on plus one or plus 2 size rims. Thus you have a shorter stiffer sidewall.
Like I said, many more unseen factors.
Of course you are totally right that one should spend the money on getting a better tire as oppose to a wider tire.
Cheers.

I agree with most of this post. One thing I do not agree with is the BFG recommendation. Compared with the Yoko ES100 or the Kumho SPT, the KDW and KDW2 have similar performance but are MUCH more expensive, and the g-Force Sport is about the same price but has MUCH worse performance.
