It appear many on here use a knobby tread 4.8x4x8 rather than the ribbed ones like the promos use. Is there a reason? I copied the LLF mini axle drawing provided . I came up with about a 5.2 degree angle of rear wheel cant. Is that right? Does any one prefer any more or any less? I started building my mini 2 days ago. It's really different than anyone that I have seen. It is monocoque construction with an enclosed front fuselage and front wheel. Don't know if it will work but am willing to try something new.

Yeh as Vic said, a knobby tyre is what comes fitted to the Falshaw rims.

I keep rotating/exchanging them with all the new ones I get, to wear them evenly.

My LLM axle angle is 5 degrees and the rear wheel can simply be turned 180 degrees to wear the other side evenly.

Our “Pink Lake” in Esperance, is not abrasive, so my wear problem is only at Lake Lefroy and I'll put up with any amount of wear to sail there.

At Elvington, UK which is an old airbase (one of the designated European sites for landing the space shuttle if needed) we get really high wear rates so the knobblies go on the club yachts as they last a while and the ribbed get used for racing....there is another variable as well which is the number of plies, as these tyres come in 2,3, or 4 ply.

I use 2 ply ribbed tyres on my ski axle minis. They are used on tarmac carparks mostly
and stand up quite well. They are set at 5 degrees but with the flex of the axles they end up with more camber depending on weight

Maybe you are not sailing hard enough!!

I had a favourite sailing spot in the Gladstone Harbour precinct which was a hard standing area that was "hot mix" tar sealed, about a half an acre in area and 200 metres from the water's edge (great wind exposure).

A pair of new ribbed 2 ply Deli Tyres (standard issue on blokarts) could be turned into baldies by the end of a good 4 hour session. Go 6 hours and you are down to the canvas.

In the gybe turns you could hear the sweet sound of the rubber being peeled off. The slide outs were real ooombacacky ( a word from my early teen contemporaries used to describe anything that gave you a hard on) .

I also tried DEESTONE tyres (2 ply rated) which stood up better, possibly because they are nylon. However, they are slightly heavier and not as well balanced which robs speed.

I have not yet sailed a dry salt lake bed but until I do my opinion remains that "hot mix" bitumen and smooth concrete are the best for SPEED landsailing.

When I have found my 100 acres of ocean front land, had it laser levelled and sealed with "hot mix" bitumen, I will let you all know.

The landsailing will be free because the on site tyre shop will fund it all.
