2 row front tyres?

[Npdp72]

Are people running these 2 row front tyres (U6797) on full width 2wd rims and with standard front medium foams (U6733) like it says on the Schumacher website?

I want to try them on my KF on grass, any advice / experiences welcome.
Thanks.

Tried them on my RB6 at the weekend and Tuesday evening, our track surface is 90% grass and 10% astro and in the damp early morning and late evening they were brilliant, wasn't to sure on them for the rest of the day, worked well when the track was blown
