New to site and need wheel advice, thanks

[RK05_BMW]

I have a 320Ci m sport coupe and am wanting to change the wheels, I am wanting to get the 3SDM 0.06. they are 18x8.5 ET35 and 18x9.5 ET40, has anyone fitted these to theres? I am wanting to know what tyres sizes to go for as hoping I could fit my standard 225or235 (as I can't remember what size they are) fronts and 255 rears. will they rub on arches, or catch on lock or anything, I don't really understand the ET40 bit so am just hoping these will fit without any issues, im not lowered if it makes any different. any pics would be good, especially for these on an un lowered car as orginaly plan was to go for 19" wheels to try and close that front arch gap as don't really wanna lower it and ruin it, ect.
