15x6.5 or 15x7 ?

[bryan]

If I went with a slightly-wider-than-stock wheel like 15x7 instead of a 6.5 width, would any advantages of the wider wheel be negated by the slight wheight addition? Thanks! Also, I searched but didn't have much luck.

Wider wheels are better for getting wider tires. Actually, even if a tire will fit over both, it'll probably work with the 7" wheel a bit better since your contact patch will be slightly increased. In general, the diameter of the wheel has more to do with weight than the width.

lots of autocrossers have professed that 15x7 is way better than 15x6.5 with the same 205 width tire, even if they do weigh more.

Thanks, I will be getting the wider wheels.

So which ones are you going with? I have some ideas for my next wheels (15x7s) but I'd like to see more.

There are some custom-made Rota Slips in 15x7 with the Honda hub-centric bore available now for $115 each. They weigh 13.5lbs.

I'm not exactly sure yet, I just know what size I want. Can you tell me what the Honda hub-centric bore is? I have never heard of that. Do I need to look for a wheel that has one? thanks!

A honda hub-centric bore means the wheels have a hole in the center that fits perfectly around the hub, as if they were made by Honda.

Almost all aftermarket wheels come with a larger center bore, so that they can fit on other cars than hondas, and you need to use plastic or metal hub-centric rings to fill the gap.

This ensures that the wheel stays perfectly centered and takes some of the load off the wheel studs, but its a bit of a hassle to take the front ones off, as they usually get heat-bonded (melted) to the hub.

Imagine you have a flat, and you cant get the hub-centric ring off because you dont have the necessary screwdrivers-mallets-pliers you need to pry them off so your spare will go on.

I change my wheels back to stock on occasion for long trips, and it takes longer to get the hub-centric rings off than to do the rest of the change.

I think having the honda-sized hub is a good selling point for that reason. The only other place you'd get that is though a custom racing wheel made to your specs: http://www.circleracing.com/

Buy me some 7.5s just for autox next year. Wider wheels allows better turn in I believe. I think volks te37 and ssr c comp are the only wheels are offers 7.5.

I have metal hub centering rings, they snap into the wheels and do not get stuck on the hub. The wheels & hub rings are made by OZ, so i'm guessing they thought of this beforehand.

I thought a wider wheel equalled sluggish turn in, but increased cornering grip, which equalled higher cornering speed.

A little toe and caster adjustment can make your turn-in uncomfortably aggressive if you want.

A thicker rear sway bar, and thinner front sway bar will help turn in too.
