Thank you very much to everyone who advised me to replace the Bridgestone run-flats on my 35is with 'normal' tyres.

In the 120 miles since the change yesterday, on A, B & M roads, there's been no tram-lining, no lurching sideways, no 'Whoa-what-the-Hell-was-that?'.

Instead, the car drives as I think it should ... very well, indeed.

Hi what did you replace them with make of tyre also is the ride quieter and softer also have you a space saver now in the boot incase of puncture or a can of tyre weld ??

Eureka.

Pirelli P Zero
Quieter
Not as bone-hard as run-flats, but certainly not soft
Much, much, much better
No space-saver
Aerosol - to be replaced by compressor & gunk

Just a tip from my years of experience of no spare wheel and non run flats - 2 cans of the largest Holt's tyre weld (others are available) and you won't need a compressor, there's enough air in them to get to the required pressure and then just check at the nearest petrol station
Btw, only works with small holes obviously, but 2 cans seem to always put more than enough air in the tyre (30-40psi). HTH

I twitch when I hear those tyre repair aerosols mentioned, a few years back I limped into work with a puncture in my smart roadster & crept out at lunchtime to fix it with the previously mentioned item
It was a boiling hot day and I was feeling pretty glad I wouldn't have to pump the tyre back up in the heat.
I hooked up the device to the tyre & flicked the valve open & the complete plastic assembly on top pinged off.
The contents shot out into space like mount Vesuvius erupting, then I realised the glue like substance was descending onto my boiling hot car
It took me weeks of washing/polishing/scraping to get the smart looking normal again.
I can't touch those things since then (the tyre weld, not smart cars)

That sounds like real bad luck there Smartbear, never had anything like that happen to me. I know a lot of people say they have never got them to work but they've been a life saver for me on many occasions. Holts ones seem to work best.

Thank you, I needed a good giggle after a crappy day

Thank you very much (again).

Yep, me too.
