People did say it at the time. Perhaps not everyone but some people.roofer said:
I chose these sizes because i'm getting a set of Alpina Dynamics in 8"/8.5". You can fit a 255 from an 8" upwards rimpreppeller said:roofer, I notice you went for wider tires but with a profile which kept the rolling radius within 1%. Do the wider tyres fit on the standard bmw 18" rims? because mytyres have plenty of those sizes in stock.
preppeller said:Also, does it bugger up the flat tyre indicator on the onboard computer?
I was under the impression that the tyre deflation detection didn't measure pressure but monitored the rotational speed of all four wheels. When a tyre deflates (even a RFT) the overall radius decreases, so the rotational speed increases - the ECU sees this and interprets it as a flat tyre. Hence the need to re-initialise the system every time you change tyres, or (strictly speaking) top up tyre pressures.Tyre pressure monitor works fine
That it does 8)So, in summary, it should work perfectly well with a non-RFT
I'm jealous roofer- my RFT are too new to change but will certainly be considering this option later. Can you tell us whether you needed to modify your guards to make the new tires fit? Especially the rear- the OEM 225 is already pretty tight??? Any rub on big bumps with 255?roofer said:...For P/Zero rosso, 255/35 rears, 225/40 fronts.
Ride quality is transformed, turn in is crisp.
I will never buy a Runflat shod car again
Of courseAny pics? The rear view must look awesome
Hi Preppeller,preppeller said:The best tyre sizes which are in stock in plenty at mytyres (with good brand names and not run flats, fit comfortably on the current rim sizes and only change the speedo by -0.7% (well within boundries ie 70mph on the speedo is actually 69.51mph) are.... *drumroll*
225/40x18 on the front and 245/35x18 on the rear.
