They may be in your future Vern, but clearly, they aren't in mine.

Cheers,
Ray Hull

PS: Funny that they aren't used on the M series cars....
If you had the opportunity to read the articles you would understand that the suspension has to be designed to use the RFT's and it won't be that long before they will be on the M Series.As of now they are using them on some race cars.They did a study through Tire Rack and found that they are 10% higher in price over the conventional tires and the benefits you recieve from the RFT's are greater,
Have a nice day
cheers

What articles vern???

For sure RF tyres are a safty measure in many ways,
but at least my car's chassi do not cope with them.

Actually all E60 should ride with 225/50 17" wheels on them.

In BMW measures the sports cars are branded M!

I'll agree with you, although 18's probably would be OK.

The articles are in the Roundel magazine available to BMWCCA members.
Correct me if I'm wrong but aren't all E60's with the Sports Package have the suspension designed around the RFT's and 18" wheels
cheers

My Ride: '04 545iS 6 spd, bought new via eBay, 11/05; Blk/Gry, Cold, L7, PDC, BMW Rear seatcover for pets. First "Bumwa" was a new 1971 2002. High performance 5s since 1987. Beamer motorcycles too, currently on an 07 BMW K1200 GT; also a Moto Guzzi 1000 SP III.

Sorry, but there was nothing in that article to convince me of their benefits...especially cost/benefit. The idea of bragging that RFTs will be the ONLY fitment for new models is arrogant and troubling, and recalls to me the screwing I took continuously with Michelin TRX metric-sized tires and wheels fitted to my 87 535iSport 5 speed. Don't get me wrong, they were good tires, and probably the first low-profile high-performance units on the retail market. My objection was their exclusive fitment, and of course with a metric WHEEL size, you were a prisoner of the BMW-Michelin agreement.

In fact, I wonder what guys do with restored models (635s too). I'd guess those TRXs are rare birds at this point.

Contrast those repairable, comfortable, performance models with my Dunlop RFT recent experience, and it's not good. That BMW admits that the new models will have suspension designed around the tires is admitting that by default, they installed inappropriate tires on our cars; in the interest of I know not what (but I suspect they get them near-free from the tire makers that are assured of BMW cache and repeat business).

Sorry, but I 'm not willing to play, especially at those prices. The idea of a $425 tire being unrepairable is simply inexcusable in my book.

Cheers,
Ray Hull

PS: Anyone have any idea why Michelin, the top dog, isn't in this market?

Great articles on RFT"s. No matter what most of the people on this site think about how bad the RFT's are fore one reason or another RFT's are the tire of the future.
cheers
