Foams are great on prepared surfaces, sprayed with sugar water.
They will hook up great. Otherwise they slide around a bit. A very controllable slide though on unpreped asphalt.
I have no track in my area that preps the track. SOoo I use rubber tires, 24mm HPI Advans, 33r with HPi Green 24mm inserts.
Or Ofnas K-1 slick on Ofnas Hyper rims, with HPI red 26mm(firm i think) inserts. The Advans have some tread so they chew
thru the dust and debris on the asphalt. Ofnas K-1 have no tread but on a cleaner surface they can rock.
