techathy, I'm not disagreeing, just explaining why

Re: Just who signed off on the OE tyres?
But it doesn't really explain it. By that I mean the Pirelli tyre doesn't have more traction than the Bridgestone on smooth roads. It's just the RFT carcass can't keep as much tread in contact with road when there are imperfections.

But a softer tyre will help with imperfections in road surface, where on a smooth flat surface the wider tyre probably makes the difference less noticable

Broken or rough surfaces sure, but not things like 10<30mm steps, 20<50mm wide cracks in an otherwise smooth surface. With things like that we're beyond tread deformation and well into carcass deformation.

My M135i came with MPSS as standard although you could spec NRFs as an option. If I go for another will definitely be speccing runflats, I have a love hate relationship with the Michelins but generally fed up with them and never liked the thought of relying on a can of hopeless foam.

My Discovery 3 was fitted with Pirelli std rubber when it left the showroom - they lasted until 20k when they were goosed!sars wrote: ------ the downside is that they won't last long
I fitted Vredestein wintracs at that point and 21k miles later they still look good - I would guess about 5-6mm tread depth.
Like most, I had the fear af rapid wear rates but I needn't have worried.
(That's with 2900kg of car depending on them)

So I bought a 35is with all the toys to play with.

Re: Just who signed off on the OE tyres?
Problem with RFT tyres is the moment you have any sidewall damage then you can't trust the tyre to run flat! Got it a little wrong & bumped up a full height kerb... light scuffs on the sidewall, especially round the shoulder? Well if you have a puncture you now have to treat that tyre like it's a non-RFT tyre!TitanTim wrote:My M135i came with MPSS as standard although you could spec NRFs as an option.
