Tramlining
I really need to do the same thing.
I didn't realize it was the RFT's that caused the tramlining. And my odometer is off a couple of MPH's also. I already have 18's on the Z4 but my wife complains about the rough ride. Sounds like this will fix all the problems. Except one.... Don't think she even knows there is no spare in the trunk |

All I've read are posts about how much better the car rides and handles. You do lose the relative "safety" of the run-flat, but the only flat tire I've had in the last 20 years was a run-flat on the Z. They're expensive and they wear out quickly. They make your Z ride and handle like crap. Not a great trade-off for being able to drive on a flat for a few miles.

With respect to flat tires, get yourself a AAA membership and / or a roadside tire repair kit, can of spray flat tire goop that reinflates and plugs the tire and a 12 volt compressor. With the exception of the AAA membership, I bought all of that for less than $100 and keep them stowed in the trunk in one of those black reusable grocery store fabric shopping bags that are so popular these days.

And don't ever be fooled by the "safety" of run flats. If one gets a flat with a rft. it does not mean you can just blast down the road to your destination. You still need to stop driving within a very short time. And try finding a new rft at Billy bob's gas station in the middle of Nevada on hi-way 50.
Only two reasons BMW did rft's 1, Money saved from no spare. 2, weight. But mostly number one |

I just can't see the advantage because of the cost and trouble involved. I have towing on my insurance for up to 150 miles so no worries from me. I just changed the rears to BFG G Force Sports and the ride is so much better. I waiting for the fronts to wear out and then I'm replacing those too. They are wider at the rim than the RF's.

Got rid of my RFs today finally. I noticed the difference just pulling out of the service area. Already felt smoother and quieter. Major difference on the highway. I was wondering for a sec why my engine sounded like it was working so hard at normal highway speeds. I looked and saw I was indeed in 6th, but I was turning just over 3g on the tach. Then I noticed I was at 95MPH, even though it felt smoother and quieter than 70 on the RFs. I'm going to really enjoy these tires if they don't get me into too much trouble.

The best way I can think of to describe the difference is, with NON RFT I no longer feel like Im crashing into cracks on the raod, but rolling over them instead. I cant stress enough how bad the RFT idea was for this car, and I dont think enough people realize how bad the ride is cause they either dont know it can be better or they've bought into the bumpy sports car myth according to Jeramy Clarckson - "It reminded me of a Corvette which adheres to the American principal that sports cars should have no suspension at all." He's an ass, but he's got that one pegged.

I wonder if Clarkson would have judged the Z4 less harshly, had he driven one that was equipped with conventional tires.
And more importantly, how many prospective customers between 2003 and 2008 drove a "non M" Z4 and were so turned off by the horrible feel of the run-flats that they went elsewhere and bought a different car? I think BMW could have had much better sales numbers for the 2003 - 2008 Z4 if it had been equipped with conventional tires and a mobility kit like the M version.

Definitely. A bone stock Z4 3.0i could go toe-to-toe with the Boxster (cf. Fifth Gear comparo); one with the same tires would more than hold its own in performance and ride comfort. The difference is so dramatic I have trouble believing BMW developed the suspension for run-flats - they're too good to have gone that far wrong...

I haven't had a Boxster try me yet but there are a metric crap ton of them running around eyeballing me when I'm out that it's only a matter of time. Jeremy from Top Gear is my hero.

I just made a 500 mile road trip with the new wheels and tires. I couldn't believe the difference in ride at 80-95 on the interstate. Granted, I didn't do 95 for more than a minute or two, but crusing at 80 was really nice and comfortable. Just reinforces that I should have done this a long time ago.
