My current tires are shot, and I'm considering going with SLIGHTLY wider tires... however, I'm thinking about doing this without decreasing the aspect ratio, so I'd end up with tires just a little wider and a little taller than stock. My speedometer is already reading a few miles per hour slower than I'm actually going, so I figure if I go with 215/70/15 instead of the stock 205/70/15, it will actually make the speedo more accurate than it is now.

Does anyone have an opinion on this? Is it a bad idea? I'm thinking that it might result in a slight loss of power coupled with a slight increase in fuel economy (particularly on the highway), since it would increase my gear ratio, thereby lowering my cruising RPM's.

I have a '98 LX, without anti-lock brakes, so that system wouldn't be affected by the taller tire. Since the change is small, I would hope it wouldn't affect the suspension or any other components either.

Anyway, I don't really know what the pros and cons of doing this would be, as far as handling, ride quality, fuel economy, etc etc. I'd love to hear your thoughts!!

Actually, Honda speedos like to read a hair faster than you're actually going. Larger tires will compensate. Had it been reading slower, larger tires would make it more inaccurate.

Unless you want to modify your suspension, I'd say 215/75/15 is the biggest you should go. Otherwise you risk rubbing.

Unless your CRV is lowere 215/70 is fine, I run that with a 3 inch drop and i get a little bit of tire rub when I turn hard right. Seems to ride smoother and softer with the larger tires. MPG and performance didn't seem to suffer.
