TyreWeld, weight saving and pressure at speed

[SlowRider]

Wondering about tyres today ... Is tyreweld any good? Can you still have the puncture fixed or is the tyre dead afterwards. Was going to ditch the spare tyre to save weight, but it didnt feel heavy enough to be worth taking out.

Why do you have to increase tyre pressure for higher speeds? Doesnt seem intuitive to me.

Personally, i ditched mine because of the hassle of moving it when the roof had to go in and out. It must be ok as many cars have it only. I believe the tyre is still "repairable" but you have to pay to get the gunk removed.

Ditched my spare and replaced with 2 tins of tyre weld for good measure.
It only took me another 5 months to remember to remove the jack and wheel brace as well !

Wondering why you need to loose weight?

Odd isn't it? Speaking as someone who hasn't got a spare (just a couple of tins of tyre weld) I'd gladly carry spare in the boot if I had one (a spare, that is -- I do have a boot (and assuming it would fit)).

From purely anecdotal evidence, I've little confidence in the gunk stuff really. The extra weight wouldn't bother me. How much does a rim+tyre weigh, anyway?

btw, I think the extra pressure for high speed driving (is there any other sort? ) is to give the sidewalls extra support and so prevent more tyre flexing and prevent overheating.

Hint:
Fill with tyre weld BUT should also be topped up with air when you get the chance (finding a petrol station that has one working might prove difficult though).

Not that much, 30 / 40 Kgs I'd guess? But they do take up a lot of space. So far I've only had one puncture (nail) in about a quarter of a million miles. On that basis it hardly seems worth wasting half the boot. But I did take a full size spare to Zolder, just in case I damaged a rim while I was on the track. Not likely, but it's a long way to get back on three wheels. Rest of the time I'll take my chances.
