I want to get these Vossen 078 silver rims for my 2004 (non brembo) coupe. The size of the rims are as follows:

Front 20x9 offset 25
Rear 20x10.5 offset 30

I want to make sure these rims fit correct and dont stick out any. I would also like to know if I have to roll the fenders. I am running stock suspension now. What would the correct tire size be for these so there is equal footprint? I dont want to stretch them too much but still want a clean look.

I have attached a G with the rims on but I want to make sure thats how they will look on my car.

Thanks in advance for the help....

Those offsets wont stick out at all, they'll actually be a little sunken in. You can run a 255/30F 285/30R with those offsets easily and still not roll your fenders.

Would 245/30F 275/30R be stretching it too much on the rims?

I can get some Falkens mounted onto the rims from vendor for another $1000. Sounds like a good deal but im not sure of the quality of Falkens or the warranty.

Please help with correct tire size. I have seen that 255/30 and 285/30 are a good combo as well as 245/30 and 275/30. I would assume the latter will be more stretched out. Please let me know how bad it would look with 245/35 in front. Will the profile look funny or performace be impacted. I would like to get as much meat on the front as possible without any side effects.

Thanks....

If you want to run a 245/35 on the front, you'd definitely want a 285/30 on the rear.

i have those on my car. my bodyshop rolled my rears just a lil bit on the inside because i have greddy type s coilovers.it was just a precausion but prolly wasnt needed. i also got the falken f452's for my tires, 30 series 245 front and 285 rear. but my bodyshop said our cars have so much tire room we could prolly fit 300's in the rears. in that pic of yours, that car is lowerd. i would recommend coilovers because you can control ride hieght. my greddy type s are pretty good, look into those.
