What size wheels do you think you get the best performance out of?

What are some of your opinions?

Its not the wheel size as much as it is the overall wheel/tire weight


Correct

An 18" wheel with a 35 series tire CAN be the same height and weight as a  stock 15" GT wheel - depends on brands,  so it wouldnt make any performance difference unless it is lighter overall


Not entirely true. A larger diameter wheel will have more of its mass farther out from the center of the wheel, thereby making the car work harder to rotate it, even given the same weight as a smaller diameter.

The best performance gain will be seen with the lightest wheel in the smallest diameter that will fit over your brakes. This is probably going to be a 14". Run whatever tire fits your application best, speedo error be damned.

In pretty much every situation, though, you are going to have to make compromises. You need to decide what compromises you are willing to make. Do you want your speedo to be off by anything? Do you care that a smaller wheel won't 'look as cool' as a larger one? Is the tire choice you make going to be one that you can drive daily? If so, you are compromising dry traction in order to gain wet/snow traction.

All these choice are going to ultimately determine what you can run, and then from there you can take a look at the choices available in that size/weight/diameter.

In my experience, there are a LOT more choices of wheel/tire combinations in 15" than there are in 14". Rota Wheels makes a very affordable, lightweight wheel that fits our cars, and it tips the scales at 12 pounds each. If you want less weight than that, you are looking at dropping some serious change on some Volk TE-37s or SSR Competitions... about 3-400 per corner, but at 7 and 8 pounds, respectively, a significant gain. How much do you want to spend?

The best dry weather tire out now is either the Falken Azenis Sport or the Kuhmo MX, but running those is going to compromise snow traction, and to a degree, wet traction (as the tire ages and tread wears). Figure on getting around 10K miles on a set of these, too. *wince*

It is all about compromise. smile.gif
