ALLOY WHEELS & RFT's

Hello fellow Z's,
I'm hoping a few of you can chip in with your opinions and knowledge, here's the deal...

I bought my Z4 around a month ago and I was planning on ditching the run-flats as many of you have advised on other posts. Even more so when I found that the rear passenger tyre had been recently replaced with a cheapo budget tyre! So i'm rolling on 3 potenza RFTs and one KJUG3455GOFASTBUDGET GT'S (joke-no idea on the make)
Driving through town this afternoon my RFT warning light illuminated red, i pulled over and checked all tyres which seemed fine (and the drive wasn't affected either, besides the normal harsh ride of RFT'S & Low profiles) I restarted the car and held down the button with the same symbol which made the dash symbol turn yellow then off. I assumed all was fine and continued to drive on, wondering why there was a button for the RFT indicator???
1/2 mile later the car became wobbly and I felt the wallet raping motion of the updownupdown ride when the tyre comes off the rim (alas... it had)
Long story short.. kwik-fit quoted a replacement Potenza @ £275 (Nearly £300 for ONE tyre... almost punched the smiley Kwik-Fit Fitter in his fat face) Budget tyres coming in at £135 (which in my opinion is no real cheap option) the chap advised not to fit non RFT's on those alloys since they may not be designed to fit properly and may be the cause of the blowout.

I had the AA tow me home on a flat-bed and so i can take my time and perhaps order online for a better deal. I'd appreciate any advice or warnings on suppliers, changing from RFT's, size difference etc. I'm not looking to kit the car for performance, i don't corner at a million miles an hour! I just need some reliable tyres for the car considering its a 2.5 and rear wheel drive.
I'm considering a wheel and tyre package from an online company (also listing/trading on eBay) I've found M6 style alloys with rubber for around £450. This seems like an attractive deal since I would be paying out £300 for one corner! I'm obviously going to try to get the best tyre with the package and many are reasonable (Toyo Proxes seems quite common and I've heard good reviews) Another question is if I were to buy a new set of alloys would they need to be the same size difference as my originals? (i.e. I have 18" 8.0 on the front at 47mm offset and 18" 8.5 50mm offset on the rear) Would the new set need to have the same difference in width and offset? I fear this may be tricky when buying 'off the shelf' aftermarket alloys.
Finally, can anyone advise if/how any differences are dealt with in switching from RFT's. Is the indicator/sensor removed with the wheel/tyre? I'm not sure if I'd need to change anything in the process???

Many thanks in advance for any tips or information that may be useful. (Oh and feel free to suggest designs for the new wheels, I'm considering the M6 style or some similar to the early porsche cup alloys since I've always likes their sweeping style)
 
Many questions in this one but a few comments to get the ball rolling:
Not sure how you checked the RFT's when the light came on as they look exactly the same without air. It took me 2 minutes to identify which of mine was flat recently.
Firstly you can fit Non RFT's to your rims. Many have it already so the Kwik fir comment is wrong
The club members tyre of choice seems to be the Falcon 452. Run a search on it for many rave reviews.
Wheel and tyre packages off ebay - not for me due to unknown quality of the rim, generally greater weight, etc. I'd stick to OEM rims and a good non RFT
 
OK - I had read the comment 'kwik-fit quoted a replacement Potenza @ £275' as indicating an RFT had gone. It would of course have been obvious to see the tyre deflated. :)
 
I bought mine on line from Best Buy Tyres (here) and went for Michelin run flats and they are great - much better than the Bridgestones. Price wasn't too much more either :thumbsup:

others have no problems fitting normal tyres to BMW rims :)
 
I've fitted Goodyear F1 Asymmetrics to my 18"s and am very pleased with them. Local tyre fitter was as cheap as online.

He did warn me of the risk of damage to the alloy when removing rfts though. so beware. They were difficult, but he managed.
 
Me too, Goodyear F1's. Lovely tyres. Mine were £ 560 a set on 18" rims. No problems to fit, transform the car. I have a compressor and a can or gloop in the boot in case I get a puncture.
