wheels and tires

My wife just bought a 2010 328i xdrive. I have worked as a director in a domestic service and parts department. It's a nice car but the 16" wheels make it look bland. I have been doing some homework on putting 19" wheels 313 style 8.0 frt and 9.0 rr...40 offset frt and 35 offset rr....tires i would like to go with 235/35 frt and 275/30 rr...i just want to fill the gap with more wheel and tire...since it's an xdrive, i have read that the diameter needs to be real close....my question is will that combo work on my vehicle without rubbing and do you think it would fill the gap some?

I believe it will, but if I had to do it all over again, I'd go with 18s. I think the 313s come in 18s. The other issue that has been alluded to with putting 313 19s on the 328 is that the brakes are smaller on the 328 and with the 313s having so much open area, the brakes look small. If true, another reason to go with the 18s.

You can find multiple threads discussing the pros and cons of 18 v. 19. Read Nordic Kat's sticky how conducting searches.

19 inch 8" and 9" ideally 34front 37rear offset something like that have a look at realoem.com and check 19" offset

18s will look very good and they will perform better, be more durable/less prone to road hazard and more comfortable.

18" Style 313 wheels are standard on the 335is. Awesome wheels! The 335is is the first car I've owned that I have no desire to change either the wheels or the exhaust!

Hey Tom glad I found ya..Went with better judgement and chose the 18' 313's with plenty of deliberation but other than the bling factor couldn't find another excuse to exercise stupidity i.e Bent/cracked rims coupled with excessive tire wear. Thought about tearing off the run flats but this is all becoming a pain in the butt. How do the wheel wells look??Too much room?? Or just right??

There is no hard & fast answer on the fit. I have 245/35/19 & 265/30/19 on 313's. I know others who have 275's on the rear.

The problem is there is no standardization among tire sizes. My tires are Conti DW but a set of Yokohama Advan AD08 in the same sizes are a bit over 1/2 wider at the tread. When I had a Acura TL I ran Yoko 100's in a 255 size all the way round. They were a full inch wider at the tread than a Goodyear F1 in the 265 size that someone else was running.

You will just have to take actual measurements against the spec of the specific tire you are interested in to see if it will fit.

not sure what you mean that tires are not a standard size. it shouldnt matter who the manufacturer is but a 245/30/19 should all be identical in measurement from each manufacturer. I am sure there is a tolerance but plus or minus an inch, I doubt that
245 would be the tire tread width in MM
30 is the aspect ratio, tire height in percent of tread width ie 30 percent of 245 mm is 73.5 mm height( but not sure where they take the measurement, from the bead to the tread or what is showing when the tire is mounted
and 19 is the rim size in inches that the tire fits, or the internal diameter of the tire

maybe you are measuring the tires wrong. But 245 millimeters is 245 milimeters no matter what ruler you use or county you are in

Thanks for the info

245mm really actually is 245mm but it depends a what point on the tire tread the factory took the measurement, how rounded the shoulder is vs. a more square cut shoulder. Take a look at tire rack specs Conti DW[B] 265X30X19 tread width 9.5" vs. Yokohama Advan AD08 255X30X19 tread width 9.9"

So here we have a 255X30X19 tire putting almost a 1/2" more rubber down then a 265X30X19 tire. When you are increasing tire size you really need to be very careful about what you are doing. Another very critical dimension is section width which is the widest part of the tire. To wide a tread might rub the fenders & to much section width can hit the suspension components.

BTW if you really have a problem with this I can take the trouble to dig up an old picture of my 255 yokos driving over a ruler showing 10" gone from a 12" ruler. If I am just speculating about something I say that I am so as not to mislead people in the threads I am in. Just like everybody else I can & have made mistakes but generally in a contentious situation where I can I will post a picture. There is a whole thread on 255 tires on the Acurazine 3G Acura TL tires forum where I and another guys posted pics of our 255 tires & my Yokos were wider then his Goodyear's by an inch & equal to a set of 275 Goodyear's.
