@Sharp_Coyote:
What really sucks is that high performance tires cost a lot. There’s a perfectly good reason why they’re called, “runflats.”
But if you have 1 flat tire, you have to replace the whole 4 tires for over $2,000.
@W0LFB3AT5:
There are always exceptions, like mis-matched tires on an axle, multiple non-repairable punctures, or companies with fragile, overly-complex AWD systems: some require the maximum difference in tread from front-to-rear to be no more than 3/32. Like Mercedes for example, and not for a Honda Civic.
If you paid $2K for (4) new tires on your last car, just be prepared to add 50% to that for runflats on the new one :(

I still maintain you were ripped off by that facility; remaining tread should always be the main factor in whether to replace (1) (2) or all (4) tires on a vehicle.
Say you have skipped a couple rotation intervals, and your tread readings are 4/32 4/32 front (with one front puncture) and 7/32 7/32 on the rear: I'd recommend replacing both fronts. If, however, your tires are newer and @ 8/32 all around, by all means replace only (1)
Any facility that requires you to replace all (4) tires as a matter of policy, not of wear, is a facility to not trust.

Yeah, they have highly-reinforced sidewalls and beads so a compromised tire can be driven on with low or no air pressure for a short distance to be able to get to a facility without a tow.
Runflat tires should never have a puncture repair performed, as the repair-er does not know how much damage has been done to the repair-ee by driving well beyond their capabilities of range and/or speed; runflats must always be considered compromised by a puncture. This sucks when a tire is near new, yet must be replaced due to a small nail.
Runflats are also so stiff and heavy as to ride like hell - akin to walking in shoes with solid steel flat soles, no arch support, no cushioning, no comfort.
