I must have had a flat battery 4 or 5 times in a year in my first car, a MKII Cortina! Never carried a spare battery, but always had a tow rope and jump leads in that POS!Martinrcooper wrote: ↑Fri Jun 23, 2017 6:10 am But how often does a puncture happen? I haven't had one for 25 years. It has always struck me as crazy that we (without run flats) all cart around a heavy spare tyre in the boot at cost to performance, space and fuel economy to fix a problem that almost never occurs. I've had a flat battery probably half a dozen times - but nobody carries a spare battery.

To be fair I've probably only had the 3 punctures I mentioned in the last 20 years, but in the same 20 years I've never had a flat battery (my 1 Series actually told me it was dying before it did) but on that 3 to 1 ratio I'd rather carry a spare wheel or have RFTs! I don't worry about weight - there's nothing of me!
Anyway you don't have that spare wheel weight issue with RFTs!
