hope you guys can enlighten me…
…i’m in the process of modelling an approximation of the NASA LRV from the Apollo programs
but running into some difficulty as i want to do the tires.
i started a thread in the works in progress area but it’s being buried by other more impressive things 
http://blenderartists.org/forum/showthread.php?t=192489
has a picture of what i have so far, and a picture of the tire that i want to replicate
it also has a picture of my pretty shoddy tire result so far.
any help would be appreciated
