please help me understand tyres

[StuartH]

Hi all. i've recently got back into the hobby and i'm struggling to understand about tyres.

i'm running a schumacher KF2 with a 17.5t motor, while i learn how to drive again.

i have some sets of min spikes in both yellow and silver (as this is what used to be the go to tyre at the club 5 years ago)

I also have some yellow mini pins and some yellow cactus tyres.

the track i race at is a mix of short astro/outdoor carpet and a small bit of concrete. when it is wet it is very slippery and greasy, when it dries out it can get higher grip. it is also very bumpy. quite a few people run mini darts and say they provide more /or less! grip and that the mini pins might be too grippy.

they also talk about low profile and higher profile, and to be honest i'm a bit confused! i have low profile cut staggers on the front and they seem to be doing the job well

anyone who can explain this in a newbie manner please?
