Tire help?

[JC70SS]

I am thinking of getting a 275/60/15 set of ET street radials for the rear. Anyone run these on the street? Is wear ok? I guess I could also just get some 295's in a regular tire. What would be better. BTW....no tubes!

had some on my brothers challenger and took a couple months and maybe 4 burnouts to wear out. hooked ok when we first put them on there and by the end they would start to hook at about 70 mph
