I currently run 185/60R14 on my honda crx. I'm wondering if I should move to 195/60R14, and if I can, why would i? IN other words, are there advantages to this?

You can (probably) switch to 195s. The probably infers that there may be width limitations on your rims that I'm not aware of. The "why" is that wider tires generally improve handling. Basically, each tire has an extra 10mm of width that further prevents the car from going sideways, and increases amount of tire on the road. This is as I understand it. This can affect mileage alittle, but I imagine the difference in tire designs is as much of a factor.

However, the increase in contact area isn't that much. Using my loose, creative math, I guesstimated that there is maybe a 10% difference in contact area.

Narrower tires can help fuel economy. They can also be better in snow, for two reasons:

1. In the snow, you want to sink to the bottom and get traction. The narrower the blade, the easier it will cut. The more weight per area.

2. Thinking of snow in terms of aerodynamics, a wider tire will have to push more snow in front of it.

All in all, your difference isn't a big deal.

Check out this site: http://www.tolan-hoechst.com/cars/tirecalc.htm

You can do tire calculations to see if the differenet sizes keep the same overall diameter. You can go wider but you'll probably have to go with a lower profile.

You can probably go fatter if you are willing to risk the very minor speedometer/odometer error. If you can find a 195/55R14 size, that would be something to go after instead of the 60 series. That is, if they even make such a size. One sure fit is a 175/65R14 which would give better gas mileage and a softer ride. I don't know anything about snow because we've never seen it here in Southeast Texas. (the high tomorrow is 70) Chances are the ride will still be stiff with a 175 tire since this is a CRX we're talking about. Hope this helped a little...
