Flat tire fun plus tire size question!
Well one of my rears is flat, and is also beyond repair. SO, I need a new set of rears for my car. Will 245/45/16s work with my rolling radius? I've got 205/55/16s up front that are nearly shot so those will get replaced at some point with 225/50/16s. Anyways is there any problem with these sizes? I need to get the new tires tomorrow(friday) for an autox saturday.
Also, Awhile ago there was a thread about the car being too low to get the jack under when you have a flat. IT IS ALL TRUE!!! ALWAYS KEEP A BOARD OR SOMETHING IN YOUR CAR TO HELP WITH CLEARENCE!!! Anyways I didn't have one, but I ended up jacking up the car from the front point, then sat the tire under the car inbetween the front and middle points. Let down the car to rest on the spare and jacked up the middle. It worked but I do not recommend it, I would have been screwed if that somehow messed up my spare.
Hope my poor luck helps someone else.

First number is width of tire in sillymeters.
Second number is sidewall height -- this is the percentage of the width.
So time the height by 2, convert to inches (think divide by 25.7) and add the rim diameter to get height.
I think that the 225/50's are too tall for the front.
I also think that the 245/45's are just too small for the back.

"Anyways is there any problem with these sizes?"
Those are the TurboS sizes and make a fine upgrade for a Turbo. A 225/50-16 is about the same diameter as the original 225/55-16 tire. On the rear, the 245/45-16 is a tad shorter than the stock 225/50-16, but should work just fine. A 255/45-16 rear would be best, but unfortunately, only the Michelin XGT came in that size for a very limited time.

I believe there's a typo in that post danno.
A 225/50-16 is about the same diameter as the original 225/55-16 tire.
That should read "a 225/50-16 is about the same diameter as the original 205/55-16 tire".

That was my post about the car being too low to use the stock emergency jack. I just had the car lowered using the rear eccentrics the week before having a flat in the rear. Now I have two 2X4s with a 45 degree angled cut on the end as part of my emergency road kit.
