E82 / E88 1 Series (2008 - 2013)
BMWs throw back to the iconic 2002, with a renewed form and function. The smallest car in BMW's line up but still packs a punch. Available in coupe or convertible, powered by either an inline 6 in the 128 or the twin turbo rocket sled 135.

Mein Auto: 2013 128i convertible
128 wheel, tire, pad replacement

Hi all,

If you like to speed read like I do, I'll get right to the point of this post -- and you can read the details to follow if you like.

Vehicle: '13 128i convertible, M-package

Situation: 17 inch to 18 inch wheel and tire upgrade / swap / replacement, stock brake pad replacement with performance pads

Total cost of everything involved, including parts and labor: 2080.00 USD

Disclaimer--all of the following points are purely subjective and based purely on my own experience:

--The new 17" M-package 10-spoke wheels are even uglier in person than they looked in the picture when I built the car to order

--The 10-spoke wheels were a bitch to keep clean, and hard to clean when necessary (which seemed like every other day)

--I don't care for any of the newest 18" rim options from BMW that are available for the 1, so I found a really cool member of this forum and bought a set of used OEM 18" 5-spoke rims from him -- perfect fit and no issues

--Run-flat tires suck. I'm glad I did extensive research since I was forced to buy new tires as well because of rim size change -- so I got a set of Michelin Pilot Super Sport (non run-flats) and the tire repair/pump kit from Tire Rack -- also a perfect fit and no issues

--I had the stock brake pads replaced with Cool Carbon sport brake pads from BavAuto -- so far, I'm also very pleased w/ this decision and from what I can tell, there is minimal dust as BavAuto and the buyer reviews claimed.

Bottom line: the combination of upgrading to 18s and ditching the run-flat tires was the best thing I could have done without even knowing just how drastic the improvement would be.

Details:
I just took delivery of a '13 128i convertible w/ M-package, which comes standard with a 10-spoke 17" M-label wheel and run-flat tires. I was originally going to opt for an 18" rim upgrade as part of the specs when I placed the order for the car, but since none of the newest available 18s really appealed to me, I opted out of that and waited for the car to arrive so that I could see the 10-spoke 17s in person. Since they were uglier in person than as shown in the picture when I built and ordered the car, I began to look into replacement details. I also didn't want to shell out 1600+ for rims knowing that I could probably find a decent used replacement set from a forum like this one, and also get to pick the exact tires I wanted.

So I found a set of BMW Style 264 wheels, staggered setup -- 18x7.5" ET49 in the front, 18x8.5" ET52 in the rear -- 500.00 USD w/ shipping included for all 4.

Once I decided on the rims, I ordered 215/40ZR18 and 245/35ZR18 Michelin Pilot Super Sport tires from Tire Rack: 1060.15 w/ shipping.

My landlord and fellow car enthusiast recommended that I upgrade to a ceramic brake pad set -- so I did some research and while the wheels were going to be removed anyway for replacement, I settled on the Cool Carbon Sport pad set from BavAuto and got a set of replacement brake pad sensor wires in the event that the shop needed them: 302.33 w/ tax and shipping.

Delta World Tire was recommended by Tire Rack to do the installation -- I've also had positive past experiences with my nearest Delta World, so I set up the appointment -- total for mount/balance/installation of the rims and tires and to replace the pads on all 4 wheels: 220.00.

As I stated above, I cannot even begin to describe how thrilled I am that I ditched the run-flats. I thought the ride experience would be rougher by increasing from 17 to 18 and to the lower-profile tire, however, it is quite the opposite. In fact, everything improved significantly -- handling, stability, connection w/ the road. I can't believe that BMW is ruining their owners' driving experience and limiting the capability of the performance and drive experience that we love that is unique to BMW w/ having run-flats standard on their vehicles.

And while it might be placebo effect, I have noticed an improvement in "bite" with the Cool Carbon pads. Objective observation: there is significantly less dust settling on the rims. I hypothesize that this is also due to the fact that the 5-spoke rim is more open to air flow for the dust to escape, and also has less surface area to hold dust than the 10-spoke rim. I've had similar multi-spoke and 5-spoke setups on previous cars I've owned, all with standard brake pads, and I feel like the 5-spokes always stayed cleaner, and cleaning was much quicker/easier with the 5-spokes. Anyone who can reject this hypothesis and offer a different explanation -- please do -- I am always looking to learn something.

I hope this post helps to encourage and inform any of you who may be considering the same or similar situation in the future. --JLR

Mein Auto: 2010 MB SLK & BMW 135i
On my Mercedes, I installed Akebono pads, and they work well with no dust. However, the OEM pads are softer and have a bit more bite. BTW, I have a nearly new set of pads for an SLK if anyone is interested.

Akebono makes pads for nearly all BMWs except the one, but I expect this to change soon. Incidentally, I have found Amazon a good source of parts for the Benz - maybe the Bimmer?
