What size tyres for 17x8 rims?

[m3ben05]

Im not sure what size tyres i need to go for for my new rims, they are 17x8, any thoughts?

[Jimbob]

I'm planning on 215/40/17 on 17x8.5, still a bit undecided though!

[m3ben05]

I have 16x8 at the mo with 16/40/225 and the tyres seem to fit ok. Will 215 fit ok or is it better to go for the wider ones? There are not many around at 17/40/225

My 215 40 R17's rubbed on the rear arch (but i dont know how wide the wheels are)

[m3ben05]

there for an M3 so i shouldnt have to many probs with rubbing (hopefully)

Il get 215's if they will fit i think

ive got 16x9J all round, running on 215/40/16 for the euro look

[m3ben05]

well if yours are 9s then 215 should be no probs running on 8s yea?

[TW166Y]

u will be fine mate, mine went on no probs without a "cheater"

8.5x17 i have 215/40's
10x17 i have 245/35's

a bit beyond recomended limits but i tooks good, never had any probs and i doughnut the shit out of them!!

[panesar_e30]

i would go for 205's. on 8j thy give a stretched look. 205/50/15.

[gav_s14]

If they're the 8x17Et20 rims then 215/40ZR17 is the correct size for your M3.

[Mr_Rossy]

I was thinking about putting 205/40/17's on my new 17x7's

What do you guys think ? Should it be 215 or would the 205 stretch be better (Baring in mind the wife is driving the car, kurb'age !!!!)

Cheers M

The right size for 17 x 8 would be 225/ ratio (you will have to work out what your standard is an subtract the inches to keep the rolling radius within range)17 - 225/ratio/17
