i think im getting these! lol should i do 245/45/18 rear and 22540/18 front will i have any problems like rubbing and stuff??

 

From what I hear that should be no problem, but I'm not the authority on that. I would imagine it has more to do with your offset on your 18's than tire size.

 

245/45-18? WAY too tall! You'd want a 245/35-18.

And, personally, I'd go 255/35-18 rears with 225/40-18 fronts. Or 215/40-18 fronts with 245/35-18 rears. Actually, I'd probably prefer 215/40-18 fronts with 255/35-18 rears.
225/40 is going to be visibly taller than 245/35 (big fronts/little rears look).

As mentioned, what widths FIT is going to depend on your wheel offsets. What are they?

 

I'll be tracking a set of Star Specs tomorrow, 215 F / 255 R. Looking forward to seeing how they do against old RE050's!

 

they are better!

 

Better by an order of manitude. But, still not fully on the bandwagon. The xs is a better tire for initial turn-in.

 

Turn in, steering feel, blah. Ultimate grip turns quicker lap times.

 

Indeed, these are quite a bit better! with -1 Camber F and -2 Camber R, car was pretty neutral. I need to work on improving the nut behind the wheel, but I have no complaints of the tires. Gotta see what kind of life I'll get out of them..

 

 

I have a set on my STi and I love them. They're by far one of the best tires I've ever run and I've experienced quite a few:

Falken RT-615
Hankook R-S2
Bridgestone RE070
Bridgestone RE01-R
Bridgestone RE11
Falkern FK512

They're certainly not cheap IMO ($225 a piece for 255/35/18 on my STi) but they're less expensive than their Bridgestone counterparts.
