Thursday I had a blow out on my rear passenger tire.

I have Pirelli Scorpion tires on all 4 wheels which were new at 144,000
miles, I now have 173,000 miles and the other 3 tires are in great
condition (I don't lrive like a maniac).

My plan is to replace both rear tires with new Pirelli Scorpions and to take
the rear right tire and use that as the spare i.e. the rear tire that didn't
blow, and which has 29,000 miles on it, will then be my spare.

When I saw how good the tread still was on the blown tire I was surprised at
how good it looked. The last set of Scorpions I had lasted well over 80,000
miles.

My question is: if I repace two tires (they will always be on the same axel)
is this acceptible, or do I have to replace all 4?

It will be fine to replace the two tires.

Assuming that your inflation pressure was correct, why did the tire blow?

I have driven for hours at sustained speeds of 180 KMh and never had a
blowout.

I believe that all things being equal you have a defective tire to make a
claim against with the dealer/manufacturer.

1. Define "blow out". Is it really a blow out? Or just a nail hole?

2. It would help if we knew whether your car was 2WD or 4WD or AWD.

3. If you replace two tires, put them on the front axle so you can take
advantage of new tires on the end that does all the steering. The rear
end doesn't do much in that area and can have the older tires.

Sure you don't......that's why you have Pirrelli Scorpions.....only used
for going to church on Friday nights.

You really only need to replace the one that blew. You're talking very
minimal diameter difference and unless you have a full positraction rear
end, it won't make a gnat's a.s worth of difference except in your wallet.
