Ok so i lowered my supra with koni shocks and eibach springs, now the rear size tires are 265/45/18 and they don't rub, the front once are 245/45/18 and they rub. The suspensions and springs are used but almost new. Now is it my suspensions fault or the tires too big for this setup?
Tire question.

245/45/18 seems a bit tall. You want to try and stay with the stock height. Which would put you around 245/35/18. A 245/45/18 is almost 2in taller than a stock tire that is probably why your tire is rubbing the strut. You also need to find out if your wheel has the correct offset. Go to a tire shop and they should be able to set you up with the right tire and wheel size if you are bent on running 245's up front. I run a 235/40/18 in front and 275/35/18 in the rear and have no problems.
If you go to tires.com they have a tire size calculator on there. You type in the stock size and then the desired size and it will tell you the diffrence in size. Try to keep it the same height. Your speedo will only be off if the rears are not the same height.
MkIV TT wheels are 17x8 and 17x9.5 F/R respectively.
Crypton is bang on, 245/45/18 doesn't just seem too tall, it is way too tall.
225/50R16 (Stock Dia) is ~24.9"
265/45R18 dia is ~27.38", 9.25% dia difference
245/45R18 dia is ~26.68", 6.86% dia difference
In short, your tires are WAY taller than they should be. I'm gonna assume that since you're here asking these questions, it wasn't intentional either
You could consider these sizes:
265/35R18: 25.3" tall, 1.78% dia difference
245/35R18: 24.75" tall, 0.41% dia difference
I should also point out your speedometer will be reading 10% slow with your enormous tires: so if it says 60MPH, you're actually doing 66MPH.
EDIT: Nice catch Shaeff
