Tires: How wide can you go on stock ray wheels??

How does widening decrease safety? and traction? Your gaining traction if anything.

You are stretching a tire beyond its recommendation, there is a reason for that. For racing, it is probably okay. Street tires? I don't know.

The car already plows like a truck stock, extra wide tire in the back and still the skinnys in front? The car will turn worse than my Prius!

If anything you will be making the tire bulge as your putting a slightly to large tire on the rim as opposed to the stretched tire that is on the rear rim now. Also you can go 275 on the front as many people have and that will retain the same 30mm difference in width between the front and rear of the non-Nismo cars. If anything your actually reducing the difference between going 245f 275r to 275f 305r, from a 11% difference front to rear going to 10% difference. Whopping difference, I know

Hi,
Small tires up front and large tires in the back do not mean that the car will turn worst then a Prius! IT depends on the car’s need... Check out the Ferrari Enzo for example:
FRONT 245/35 ZR19 – REAR 345/35 ZR19 !! And I am pretty sure it handles pretty well

But I agree with you and most of the others that you should not stretch a tire beyond its recommendation. A therefore, I do not suggest going with tires that require rims of 10.5” if you have the stock wheels. ...I won’t !

Too bad I can't find 305's that fit on 10" wheels...

Thats exactly what he is saying, the car needs larger tires in the front as it already understeers with 30mm difference between them. So by making the difference front to rear larger by going bigger in the rear and staying the same in the front your going to have more understeer.
