Hi Ben!
Wow, amazing info, really helpful. Many thanks for this.
Personally, I agree with Tom that 72 psi can be a good option for usage and you won't face any troublesome issues with this.
As for the pressure, it's easier to drive at 72 psi than at 80. But it's up to you to decide for sure what's more convenient.
As for the brand, I tend to Toyo, if comparing two abovementioned ones. They are cheaper and other options are nearly the same.
I've bought mine here
giga-tyres.co.uk and happy with them completely.
And what are your favourite??
