Well to be honest, no they don`t.. I strap mine in the back. I have no rubbing issues though!!!

Thanks gentleman, I thought that was the case from my reccolections of previous posts on tyres.
I'll stick with the 255/60 or 265/60 but will have a serious look at the Falken I think if I move away from the Pirelli AT+

So Peter, are you looking for something a little more aggressive or better wearing or ?? than the AT+ Pirellis?

I did look at fitting my BFG 285/60 once and then shook my head as I started to wind it up... I actually run a 265/60R18 spare (Achilles X-MT) which squeezes in there nicely inflated. I wouldn't want wider as it'd hang down too much. If I ever need it I'll run a bit more air in it and a bit less in the others to get the rolling diameter about the same. Touch wood, I have never needed it yet. Sensibly I should probably get a 265/65R18 spare and just deflate it and cram it in.

Air pressure doesn’t change rolling diameter.

Hi Mike. I'll have to respectfully disagree with you on this. It's how the cheaper (inferred/indirect) TPMS systems work. They look at the rotational speed of the wheels and if one is going faster (ie. smaller rolling radius/diameter) it must be going flat so it throws up a warning.

Absolutely. The Volkswagen system without in-tyre TPMS uses a running average ABS count to detect a flat. It’s very smart in fact how it works but it can be slow to detect in certain circumstances. I’ve found it successfully indicated a tyre with a slow leak that was under-inflated and and a blow out (but that was obvious anyhow!).

Hi Gavin, actually I was looking for an option that might give me a bit more sidewall, certainly not interested in any rubbing/contact or spare that doesn't fit. Wasn't really interested in going wider than 265 either, my AT+ is 255 and as an aside with the slight reduction in rolling radius from the D697's that I took off I think the car holds top gear when I am towing the van better than it was doing with the D697. I understand of course that more sidewall will take me back to the previous condition. I think the AT+ have been excellent in all but one respect, that being sand, but I would buy them again without hesitation. Even at 90~110kPa there doesn't seem to be much bagging for sand work, at least that's my impression, no clue really if other 60 profile tyres tend to spread laterally rather than longitudinally at low pressure.
I guess I am broadening my horizons thats all and the conversation in this thread intrduced me to RT style, so there you go.
