My bad,...were you being sarcastic? I'm a little slow this morning.

Centrifigul force when driving is not enough to overcome the difference in rolling diameter between the front and rear, even if this was the case, the rear would also be subject to the same forces as the front.

guess what guys.
I have another screw that is poked into my rear left tire, on the Michelin PS2.
I will see if the tire will go flat tomorrow morning.
If it doesn't, I would probably drive to America's Tires to have them fix it, or replace it ( I think that's part of the warranty that they offer).
If it does go flat, I will change to spare and drive to get the tire fixed.
The question is:
Can I drive on the spare with 3 17inch work cr-kai with 225/45 17?
Will the car be tilted to the back?
Thanks again.
I think i am having really bad luck this year.

man, sorry to hear that bro...
use this and calculate the difference in diameter...

Don't worry about the width, just the diameter. if it's just a little bit off and a short distance it should be okay.
Good luck! and I mean it!

I just received a ticket in the mail. CVC 21453 A.
It's gonna cost $360 !!!!!!
and if i wanna go to traffic school, i would need to pay 390 !? and i thought going to traffic school would reduce the penalty.
I cannot recall what i did on that day, and that i don't think i have ran a red light. I haven't gotten a ticket in the past 6 years, so i believe i drive safely, and would not risk my life running a STEADY red light.
I think i am gonna call on monday to ask what did i exactly do.
I think i need lots of luck this year.
No I wasn't being sarcastic. Seriously go out and look at your front and rear tires. Measure the distance from the ground to the top of the tire on the front( lay a stick acrosss the top of the tire and measure from the ground to the stick to get a good measurement) and then measure the rear tire. The difference in overall height is just as much as if you were to compare a bald tire(in the rear)and a brand new one.
Centrifigul force when driving is not enough to overcome the difference in rolling diameter between the front and rear, even if this was the case, the rear would also be subject to the same forces as the front.

The diameter doesn't matter. It is the circumference that counts.
If you lift the tire off the ground, the diameter left to right should be the same as top to bottom. When the tire has load, the left to right diameter will increase and the top to bottom will decrease as the tire distorts under load. However, the circumference (which determines how far the tire travels in a revolution) will not change.
