If & when you decide on new tires, you might look into the tire package offered by CostCo here on the island.
It looks to be a pretty comprehensive plan with good after buy service included.
Also, they do offer that 'nitrogen' inflation. Although, IMO, the jury is still out on actually how much of an advantage that is for non-commercial users. Still, if it has a good side and its part of the package - good for them.
Paper on tyre failure mechanism. (Its specific to tread separation, but the conclusions may be generalisable)
I think this research arose out of US litigation and recalls over apparently tyre-related Ford Explorerrollovers, with associated mass-recalls of Firestone tyres.
N filling is mentioned towards the end. They find a 70% reduction in rubber deterioration compared to air.
As they point out, you can't get the oxygen below 5% without repeated purging, which I suppose Costco might not be willing to shell out for.
