Hi All 
Installed mod successfully etc, I can select the slicks etc  no problems, in garage if I turn on forces view I get nice looking visual of slicks or rally tyres etc  ok, but in game they show as normal road tyres (visually) in game temps show no change from road tyres. track times  show no improvement ( testing with AI 100 + laps, cars  appear to have no better grip on "slicks" to road tyres.
testing with my own driving can't see any real difference in grip levels
 
Wondering if the mod actually is working or just allowing a non functional selection? fooling us into thinking we have slicks?
 
Any comments from the programmer? I'd love to get this sorted.
I run Athlon 3000+ system ati 9600 windows xp pro sp2
