I used to use something similar when I was big into my R/C car racing... but these slicks should be ok. They're only 2 years old and have been in the loft (nice and warm) since I bought them. UV lights does more damage to the rubber.
I'm hoping they're just hard compound tyres... I'd need to check the number on the side. I'll get softer ones if they turn out to be a handfull
