G'day. I recently managed to get the Hasbro re-release of MP-10 with Vector Sigma. Pretty much perfect. Real happy with it.

I was watching Optibotimus' review of MP-22 Ultra Magnus, and in that he mentions that he hates rubber tyres as they split and crack over time. This has happened to his MP-10 and he showed it

Now My MP-1, MP-2 and new MP-10 all have perfect rubber tyres. As do my G1 Prime, Magnus and cars. So I have not experienced any tyre deterioration over time. Am I just lucky? Or is this something that has affected Australian collectors? I'd like to think that my new MP-10 has a decent shelf life of at least a few decades!

I'm thinking maybe Optibotimus' MP-10 has just been subjected to dramatic room temperature fluctuations, hence the tyre damage.

Would love some insight and possible preventive measures.

cheers
