    I know its been discussed to death, ive tried searching but need tyre size recommendations please. I am not wanting a stretched look, not the rubber band look, nor a big bulky look.
    Im after nice straight/square sidewalls and recomendations as to what would be the correct size tyres for my wheels.

    I have always stuck with oem size wheels and tyres, but these wheels have me baffled.

    Wheels are BBS RS2's. Size 18x8.5 fronts and 18x10 rears. Tyre im looking at is michellin cup2.

    I was looking at the oem csl tyre sizes 225/40/19 front and 255/35/19 rear, but my wheels are a half inch wider so unsure if that would stretch and look too narrow. i already think the rear oem csl sidewall is too narrow on the oem csl wheel.

    Any recommendations for tyre sizes for my wheel size? if you have same size wheels as mine, what do you use? also any pics would be great.

    I'm pretty sure CSL sizes are 235/35/19 and 265/30/19

    yes sorry your correct. I quoted the oem 19's size not csl 19's.

    so my wheels half inch wider. do you guys think this will look too stretched if i went for oem csl tyre size?

    I have 235/35 R19 on my CSL rep fronts, perfectly square sidewalls (8.5j). I had 265 on the rear (9.5j) which looked square IIRC, but now have 255 and they taper ever so slightly, so I would say you want 275 minimum on a 10j. I love the slight taper, but it's noticeably not "square" on the sidewall.

    That is perfect ADL!! The wheels I have are similar to the rc 300/301 as mentioned in the thread. Mine are the rs700/701. Although personally i prefer and think, the RC300/301 gives the car a much cleaner look.
    That is such a useful thread Going to give it a good read now!

    I'm going through this now with my RS2s - I've ordered 245/40/18 for the fronts and 275/35/18 for the back, haven't got the tyres yet but really confused as to whether they'll fit - plenty of people are running either 245/40s on the standard 18 (albeit 8", so .25" either side narrower) and in the same breath people run 265/35/19s on ET35 19" Arc 8s at 9.5", which works out to be more or less identical to the ET22 8.5" RS700 up front.

    Think I'm going to get my tyres fitted and play with camber, see what fits. I used to run RC300 reps on standard camber on a 225/40/18 at ET13 and that tucked/fit really nicely, if you look here: https://www.willtheyfit.com/index.p...2=40&wheel_size=18&wheel_width=8-5&offset2=22 it comes out pretty similar so with a touch more camber, should fit? Who knows.

    I found 245/40 and 275/35 to be a really good match to the 235/35 and 265/30/19s I have now, so hoping they fit.

    Just a bit annoyed that since I've bought my RS2s (and then had to refurb) every man and his bloody dog on here seem to be buying them as well :p

    How much neg camber are you running now?
    Im guessing yours are the same 8.5j front and 10j rears?

    Because you have done your outer wheel lip in black, its really difficult to judge, as at the moment in the pics its made the wheels look really small and too much rubber for my liking. Or does it look like that in the photos due to the black lip and very different in real

    Yeah it's easier to differentiate in real life, the pics don't look great tbh.

    Yes same 8.5 front and 10j rear, standard offset, no spacers. I've just maxed out the OEM top mount for camber, think it's about 1.5 deg negative? just basically slid them as far back/in as they would go, which did give a noticeable increase and just allowed the 245s up front to tuck in.

    If I was doing it again, I may consider 235/40s on the front, but the 245s don't seem to rub so I'm less inclined to change now.

    Lips will change, but I'm going to do that over winter I think after they took so long to complete the first time!

    Im still waiting for my valves to turn up. Once they arrive i can look at having the tyres mounted and have the allignment sorted.

    Im tempted to have mine refurbed in gloss black.
