I'm a firm believer in that you should not be getting wider tires than you are comfortable sliding in emergency scenarios. Of course, you may be more comfortable than I. If you are petrified of all 4 tires sliding and therefore don't know how to handle it, your tires are way too wide and therefore you are above your safety threshold.

My 2 cents
You are comparing two totally different vehicles, one of which is AWD.

Comfortable sliding in emergency scenarios? WTH?

also, FWIW, i can definitely tell the difference between 215 and 225 fronts.
can't speak for the rear, as i have only run 255s

So much grip it's getting dangerous LOL..

You shouldn't be pushing ANY tire to the limit on the street. More grip means more safety in the case of an emergency, not the other way around.

[QUOTE=PJCC,Sep 29 2010, 09:07 AM] The additional 10mm per tire will give you a larger contact patch which equals more grip.

Just an FYI, changing the tire width only changes the contact patch SHAPE. The overall contact patch area stays the SAME.
I knew there was a reason for running non-staggered setups - it is the shape of the contact patch what gives you traction.

[QUOTE=Suzukaboy,Sep 29 2010, 04:44 AM]I'm thinking about Star Specs, 225/45, 255/40, but I see the the 215/45,245/40 combo saves a few bucks.

Since I posted the question I looked at the specs and the larger set adds 3 lbs. to each front and 2 lbs to each rear. The larger set adds 1.2 in. Diameter to the fronts and 0.3 in. to the rears. Is any of this significant for a street car?. Thanks for the input so far. I admit I didn't get the emergency sliding thing either.
generally speaking:

215/45/17 : 24.62" OD
225/45/17 : 24.97" OD

245/40/17 : 24.72" OD
255/40/17 : 25.03" OD

a 1.2" difference would be significant, but that's not the case. .30" is...something, but whether or not it's significant is up to you.


hope this helps

Sorry to long post, but I hope someone is actually interested in this, I'll be long winded. Two friends of mine just damaged their cars for possibly this reason, its heavily on my mind So here I go.

Okay, I don't even understand what you're trying to get at.

It seems to me that you're basically saying some people don't know what to do with too much grip, which.... does not make sense at all. If those drivers following you could not keep up with you because they were uncomfortable pushing their car, that's their problem, not the tire's.

In an emergency situation such as braking or swerving, more grip is always better. I've never heard of anybody having an accident because they had too much grip. That doesn't even make sense.
