[motex]

Need to know the size of the factory tires that comes on the 19" wheels of the M3

[tdizzle]

255/35 front and 275/35 rears. Same width on the 18s but 40 profiles if my info is correct.

M cars don't get run flats or a spare. You get a M Mobility Kit in the trunk.

Howdy from San Antonio ya'll.

Does anyone know if is 275/30/19 front and 295/30/19 rears will fit on a completely stock 19 inch set up?? Will they fit with appropriate spacers? If not, what I the widest one could go?

Is this ratio of tire widths optimal?

Sorry, my M4 ETA is in 8 days but i'm already feeling like I want some meatier tires though wish to stay with stock rims for now.

Here's a great link to make all your tire comparisons, I have been using it for so many years, is the best tool I have found on the net yet, hope it will help you in some way

Thanks motex!

It does help with the ratios.

Still hope someone can chime in with what the largest tires size they have gone on a completely stock 19inch set up.

Thats going to be interesting to know, I'm on the same page

I wouldn't run tires that wide on a 9/10 inch width wheel personally

They're already pretty wide for the wheels they're on. I'd maybe go a 265 and 285 but any more and you're really pushing it. I'd stick with the stock size personally unless you get wider wheels.

[BCMgunner]

Thanks all for the reply. Sounds like 265/285 may be the way to go on the stock set up.

Of interest, Per BMWUSA site, the M5 is configured as below:

Double Spoke forged light alloy wheels (Style 345M), 19 x 9.0 front, 19 x 10.0 rear; and 265/40 front, 295/35 rear performance tires1.

I know these may not fit in the M4 wheel well but still gets my hopes up for stock rims.

Are the spacers necessary, or are they for appearance?

I would like to run 275 front, 295 rear Yokohama AD08r in those sizes, but I would prefer not to use spacers if possible.

Also, has the car exhibited any odd or bad behavior with these tires? I would like to ensure that the electronics don't get confused by the slight change in rolling diameter.

And +1 for pictures, please.

Thanks

Yeah that's about what I'm thinking except I might go 265 in front. The stock tires look stretched like you should be able to run much wider tires. I'll be doing 15mm front and 12mm rear spacers on mine.

Ordered my M3 today and I'm glad about the omission of the RFTs. Do they mix the brands at the factory and if so, other than the PSS, what else do they mount?

AFAIK it is just PSS. I read that Mich. designed the tires with BMW specifically for the M3/4.

Thanks. It should work for me in Florida with our monsoon downpours.
