Help identifying these tyres

[DerbyDan]

Does anybody recognise these tyres... my mate gave them to me inside a bag with the mini decal sheet that sometimes came with old Schumacher tyres, there was no header card & there's no markings on the sidewalls so i'm pretty sure they are not Shumy tyres. They have quite a distinctive 'waffle' pattern on the inside of the tyre face & a Losi X-Pattern style small sidewall-extended rib detail. Another distinctive feature is the extension rib in the middle - like there is a narrower version but the original mould has been altered to gain width?

Here's a pic;

I have a set like them with ARP header card.

Thanks Dennis - that must be them, must admit I'm not familiar with the ARP brand..... they appear to be nicely moulded, & yes they are 2.2" & feel quite soft. I guess they were good in wet conditions?
