If the outside dimensions are exactly the same or smaller, then yes it will fit. Try a search

With 245s you may need to roll/trim your rear fenders, but that's the size I plan to put on mine after I get some new rims (someday!)

what about the front wheels will they roll clean if i turn the steering wheel to the end ?

Prolly roll okay but depends on how lowered you are. Also if you're driving hard in a corner and hit a big bump you'll probably still scrape.

im lowered with trd springz is it too low ?

Yours won't be as low as mine - but you're going up to 19" so like I said, it might rub while in motion turning tight corners.

Things working against me:
• -30 offset rims
• about an 1/2" lower than TRD springs
• I am a fat ass that drops the car another 1/2"

So I've currently got 225/45/18s on my ride (235's would be perfect dia and width on front if my offset was 40-42)

Seriously though, check out the calculator here and use the OEM specs as your guideline (215/55/17 - 17x7.5 40os)

MUCH better than the goofy Miata tire calc thingy and gives you fitment info with offsets, etc...

If you're planning on rolling on 19s then you're going to need xxx/40s if you want the closest to correct dia. If you actually use the calculator in the link I gave you then you'd see that as well.
