The longer stock antenna looked classic but the stubbier version is far more practical. Having a need to put a car cover on, it slips easily over the stub version. If I get the Dayton wire wheels i'll probably switch back for style. Problem I have with my 18" Potenza RFT RE050A summer tires is they won't wear out. I've got 18K on them and the tread depth is almost brand new.

The antenna that came with the car was loose & wiggly. The previous owner must have over tightened it or something. My teenage son purchased the short one for me for fathers day. I really like it a lot and prefer its look over the previous one. And it does make it easier when putting the car cover on.

I hear Michelin is now making PSS RFT's. They are on the new C7 Corvette but don't think they fit the Z4's yet. Now the question is, if you could get them would you go back to RFT's?

On 17" and 18" the 3rd gen RFTs would be an (expensive) option worth considering in countries with higher quality road surfaces. Especially since the suspension, steering, ABS etc are actually tuned for RFTs...

Hello all,
I had my grief with RFT and 19 inch wheels (I don't want to bore you with details, since I no longer have the Z4). I just like to pass on the tip I got from a Tire Shop Manager in the US that has seen many Z4's rear tire wear. He said;- "If you go for a trip with luggage in the trunk and lot's of driving with the top down then make sure your tire pressure is to spec. and add at least 2 PSI above specification to the rear tires" He went on "also your rear wheel camber is -2.5 degree your rear tires will last longer as will your rear wheels if you have that reduced to -1 or -1.5 degree" Anyway that is what he said, take it for what it's worth .... just passing it on to you. Happy and safe driving with your car once the snow melts

Michelin PSS sizes
Quote:
What sizes in 19" Michelin Pilot Super Sports (Non-RFT) tires did you fit? I'm struggling with availability of the original 19" width/profile for the rears in PSS in Australia, and hope you (or anyone) can assist me with an alternative. Cheers, BLKZ |

for those that are using Non Run Flats, how did you work with the tire shop to not use run flats? My understanding is they will not swap you out unless you have a spare. There must me alternatives

The car presently has no modifications. This little 335HP twin turbo will get up and go when you punch it. I was already doing close to 80MPH when the guy in the vette wanted to race. I over took him & have no idea how fast we were going. I only wish I had caught it on camera.

My work was performed at the BMW dealership with no problems. I also carry a compressor & tire repair kit in the trunk.

No issues here...$25.00 a tire to swap out. I supplied the tires from best priced vendor I could find.

Maybe its just a Costco requirement but thought it was across the board for all tire shops so they are not legally obligated to make sure you are safe. I really like the compressor with sealant idea. this should be standard for all vehicles

I use the compressor to pump up the tire from time to time if I have just a small puncture. If this is not possible I call BMW service to transport my car to the next dealer. |

when you finally get to the tire shop after using the sealant, isn't it a simple spray with water to wash out the sealant? The following seems to be a good solution to using run flats. The compressor and sealant if you want to use sealant. I like the idea of not using sealant but if you are stranded in a remote area, it may be the only solution, Also having both the compressor and sealant in one solution gives you peace of mind and allows most of us to go forward and buy non run flats without that "stranded" feeling

To be honest in Germany there are no real remote areas where you have to wait longer than an hour to get help. Perhaps that is the reason that just the compressor works for us here...
Never used that sealant which comes with the compressor, just another one in a pressure bottle with sealant included. Costed me hours to clean the rim from it. And it did not work out, because the cut was to large to seal it with the sealant... Last edited by itf joegun; 03-02-2014 at 12:22 AM.. |

peace of mind. I feel now with your input I can move ahead with non run flats. they are very noisy and you feel most every bump. With the compressor its cheap insurance and gives you something to play with while the tow truck in route.

Other companies like Alpina (BMW based more exclusive cars) never sell cars with runflats and that is also their argumentation. And for the M235i you must order runflats as a zero cost option here in Germany if you want some. So it seems that BMW also did a change in their strategy here. Anyway, I am looking forward to hear from you in this thread once you did the change and report us your experience. |
