i use saharas in 235/85/16. Your links didnt work for me so I am not sure which pattern you are considering.
I have been extremely happy with the performance off road. imvho better than bfg mud pattern (insa dakar pattern). I've been out with guys with BFG muds and often seemed to fair better - even they were commenting. i've used them in mud and extensively over sharp rock (shredded a Niva mud tyre in 5 minutes :shock:) and never managed to slice one open so the quality must be pretty reasonable especially for the price. Impressed with the on-road behavior too - no excessive noice or cornering problems. Some of the sholder lugs have come off now but they do get some pretty harsh use

.
From my experience to date (1 year of very frequent off roading) they are extremely good value for money. Like you, I was very much on a budget when i bought them so I appreciate your situation. I only anticipated a years use out of them before I managed to destroy them (they are cheap!) but looks like they will do me a second year after all.
