Vantage V8 4.3 - Cracked Tyres
Discussion
Got my TVR SX out for the Summer last year and found huge cracks around the edges of the tread blocks. Didn't wait for the MOT - binned them and got new ones. Shame as they were SO2s - but had been on the car a good few years
Moral of the story - drive more and wear out your tyres before they drop to bits

Tyres fitted to performance cars should replaced when they reach lfive years old, especially if the car is not used regularly. The date of manufacture is printed on the tyre as a three digit number (046 = 4th week of 2006)
You should really start checking them after three years. How long they last can vary widely with the kind of environment they are in.My dealer said the same to me yesterday! That mine are starting to show a few cracks. Don't need changing yet but he said in 2 - 3 months they would.
Apparently Bridgestone have stopped making the AM9 version of the 050A's and don't recommend fitting a mix of the new spec and old spec, so the next bit of bad news for the OP (like me) may be that you actually need to replace all 4 tyres!!
Is this correct of not? I had a look for tyres and black circles and Event tyres are still showing the AM9's for sale.

So if Bridgestone aren't making the AM9 version what tyre should be used?Is this correct of not? I had a look for tyres and black circles and Event tyres are still showing the AM9's for sale.

Find that hard to believe as they currently still fit it to new cars and have just released a new variant for the Vantage S.Apparently Bridgestone have stopped making the AM9 version of the 050A's and don't recommend fitting a mix of the new spec and old spec, so the next bit of bad news for the OP (like me) may be that you actually need to replace all 4 tyres!!

What did they mean by new spec & old spec?
They were hard to find after the Tsunami
Check a few on line places for stock
I tend to use Camskill & black circles
I wonder if the "not making anymore" is down to the old and new spec tyres and not mixing them depending upon which tyres actually need changing.
AM9 spec used to be "CNB" designated and the production process was changed and "DAM" became the new spec
"DAM" is PAH free (polycyclic aromatic hydrocarbon)
I copy word for word a post from blackice1 who works at AM Amersham.
"Bridgestone changed there tyres to PAH free tyres early lasy year , now if all of your tyres are the old spec , then what the dealer said is true. CNB on the sidewall of the tyre is the old ones, DAM is the new spec.
Here is a bit from a service policy Letter in December 2009
• Only install Original Equipment Manufacturer (OEM) tyres.
• Do not mix tyre types at either the front or the rear of the vehicle (refer to Figure 2).
• The vehicle can have PAH-free tyres at the rear with current production tyres installed at the front (refer to
Figure 1). Thus, if a rear tyre needs replacement, you must replace the two rear tyres with OEM tyres.
• PAH-free tyres must not be installed at the front with current production tyres installed at the rear."

Both these designations are written on the sidewall. I changed all 4 tyres in May last year and they were "DAM"
