Instead you should be compensated for your losses - the time and money it took you to repair that tyre.
Same with a web service. If I pay for 24 * 7 service and it's not working when I go to use it, I want compensation for my time and effort resolving the matter.
For some that'll be small - eg. Searching Google instead, taking 30 seconds. For others it'll be a big headache.
But downtime of 1 hour is almost certainly more costly for the consumer than 1/30/24 * subscription price.
Your contract doesn't have an SLA. If you are important enough, you can certainly negotiate one - and it will be far more expensive than your prosumer subscription.
And even then you will not get a 1:168 or 1:720 SLA like you are expecting - that's simply ludicrous and totally out of touch with every reality. Even if you were a lucrative enterprise customer (which you are not) they'd tell you to get lost.

Actually, you wouldn't get a refund at all unless you suffer damage or injury, which is an high bar to prove in court and a totally separate ball game.
