Default fitment issue... need help.

hey guys,
so im lowered on tien flex coilovers and have the 18x9 rota g forces. before i had 225/40 tires on these wheels and they were way too stretched. now i bought these tires that i thought would fit (245/40)but now are giving me lots of rubbing issues. i should have gotten 245/35 because of how low i am but if i can make these tires fit without selling them it would be awesome.
now they dont make rear camber plates for my coilovers and my shop (andrewtech) doesn't want me to go any more than -2 degrees rear camber.

i know ill be sacrificing some handling but i don't auto x my car i daily it. what are my options? i have the rears rolled... do i have to pull them too?

thanks in advance for any input.

So much fail in this thread. First, you bought wheels that don't fit. Then you bought tires that don't fit the wheels. Then you bought tires that fit better on the wheels, but don't fit the car. Now you have someone telling you to run 235/35-18 tires.

A proper size tire for that rim, on your car, would be 255/35-18, but that will never fit without a lot of fender work. I'll at least ask this, are your fenders rolled? If not, that's the first thing you need to do.

Not that he's posted an offset but I doubt 255/35/18 is what he's looking for. He has massive rims and likely an offset 10-20mm from stock. He obviously is looking for something that doesn't require massive fender work. 235/35/18 maximum rim size is 18x9" which he has. Hence the OBVIOUS recommendation. The tire is 2.8% wider than the rim so it won't be like he had before with the 225/40/18 (although this tire is spec'd to handle 18x9" rims in most cases) tire on there which is actually narrower than the rim. 255/35/18 may look more... filled out... but it is hardly the only tire size that works on an 18x9" rim. The rim is good for 235/35/18 to 265/30/18 or maybe even 275/30/18 if you wanted to push it.

Are the rims a good choice for his car and situation? HELL NO. I didn't recommend the rims though, I just recommended the narrowest tire he can get away with.

my front fenders are barely rolled but my rears are rolled flat. i'd rather not pull my fenders.
im wondering if more camber in the rear is what i need i think its -1.5.

i already am stuck with these tires and theyre not selling. so if i can make it work i will. right now the cheapest alternative is what im considering. but if you guys are telling me that the tires will never work and its better and safer to spend the money and get the right size then ill consider that too.
for the meantime im borrowing my friends 18x7.5 works.

No one uses a 235/35/18 tires, nor anyone makes a 265/30/18 or 275/30/18 tire. Like Luke have said 245/40/18 is too tall. If u don't want to chAnge tires then u'll have to raise ur car or pull ur fenders. But I'd suggest going to 235/40/18 and make minor adjustments to make them fit.

Going from 225/40/18 to 235/40/18 isn't that big of a change, so if u run -2 rear camber u'll probably only need a slight pull or might not even need it depends how low u are. 245/40/18 is just too tall in general forthe 5speed and it would take quite a bit more pullng to make them fit. So I would highly recommend u switch to 235/40/18.

Well u gotta pay to play, u can't expect to be slammed with aggressive wheels while not runnng camber, pullng ur fenders and not stretching ur tires at the same time.
