Lift off or snap oversteer is a lot harder to control than understeer. bad or mismatched tyres at the rear on a FWD can make this happen quite easily. BUT, as long as each rear tyre has the same speed, load and wear rating, exact dimensions and general wear (tread depth) then it'll most likely be OK. Just don't hoon in the wet.
Meh. Given utterly identical road surfaces and utterly identical loads matching tyres are optimal, but I'd say so long as both have the same speed rating and similar tread depth you're highly unlikely to die.
