I just bought a spare kit for the F-type and it is stamped 19" so they are different from the 18"

 

It was a front which tend to wear slower than the rears, and it was a Michelin Pilot Sport 4S which in turn wear waaaay better than the OEM Pirellis.
That said I have never tracked the car and only sometimes get the tyres squealing in the twisties so I usually get good mileage out of my tyres (all except the Pirellis that is!).

 

Purchasing from tire rack, at least in USA, gives a two year road hazard warranty included in price. My first unrepairable flat tire was reimbursed for full amount (about 5k miles on tire). Most recent unrepairable flat is in for warranty claim. I'll see what they come back with. Eases the pain somewhat at $400 plus per tire.

 

The only issue I've had with tire rack was receiving a tire that was five years old. Have to watch out for that.

 

Yep, I have bought tyres from Tire Rack in the past as they are nearly always waaaaay cheaper than the same tyres in Oz, around half the price. Well at least that held true when the Oz $ exchange rate was on a par or better than par with the US $, going back some 5 to 10 years now.
With the current set of MPS4S I bought two years ago I did the sums and worked out that with the now crap Oz $ exchange rate and the heavy shipping cost I stood to save almost nothing by buying from Tire Rack.
So I decided to buy from my local tyre shop - very close by and very handy, I managed to haggle a good price from them, I have had good service from them for years for tyre swaps and puncture repairs etc, no waiting for the tyres to be shipped, and any problems would be quickly and easily fixed.
When I see them tomorrow to get the new tyre fitted I will ask them about tyre damage warranty / insurance although they never mentioned any such thing last time.

 

Did you return it? I have heard some have been received out of round (sent back).

 

Sort of. They didn't want it back. Got a replacement. Then I put the old one on the end of lease car I returned and kept the new one.

 

Well, its good to know they replaced it.

 

The adventure continues!
On the way home from SWMBO's joint this morning the steering felt a bit "off" and was pulling a bit to the left.
Stopped for fuel, lo and behold the two day old new tyre was half flat!
Pumped it back up and drove the remaining 2 km home, thoroughly examined the tyre and zero trace of any puncture.
Checked an hour later and it had already lost a bit of pressure. Hmmm, dodgy valve or hairline crack in the rim thinks I. Pumped it back up again and drive to the tyre shop that fitted it (only about 2 km down the road).
They chuck it in the water trough, hey presto leaking air from two or three spots around the inner rim.
So they pulled the tyre off the rim and discovered some traces of burnt on rubber from the blow out on the inner edge of the rim, enough to cause the tyre not to seal 100% over those spots hence the slow leak.
The tyre fitter filed all the old crud off, refitted and rebalanced the tyre, rechecked for leaks in the water trough - none - so chucked the rim back on the car, all good to go.
Well so I thought!
Just as I was hopping in the driver's seat to drive off I saw a couple of small froth bubbles on the edge of the rim, of course this time on the outer rim.
Tyre fitter checked, yep, definitely (still) leaking air.
So start from scratch again, rip the wheel off, test in the water trough, yep now leaking from the outer rim, rinse and repeat previous operation.
This time I stood over him at the water trough and made sure he checked both sides for leaks twice before giving the all clear and fitting the rim back on the car.
Got home, checked the pressure - 42 PSI!!!
Way too much for my liking so let it back down to 36 PSI.
Moral of the story - if you have a bad blowout and are forced to drive a bit further on the destroyed tyre, the heat will melt the rubber on the edges of the tyre where it joins the rim and some of that melted rubber will stick to the rim real hard. Make sure the shop that fits the new tyre thoroughly cleans the burnt crud off the edges of the rim before they fit the new tyre!
