Rear tire width requirements in relation to HP?


So, basically I learned from research is that pinion snubbers help reduce wheel hop and twisting of the rear. Some say good springs will make it no necessary to have a pinion snubber, but others say that it is important to have one because the higher hp you go the more it will come into play. So, it is a good idea to have? I am just using the ride for street cruising and some fun, with 235- 250 hp in a 70 dart, is it really necessary? I have extra stiff hemi springs I was told...
