Rear tire width requirements in relation to HP?

Spinnin ain't winnin but less likely to break something.

Grippin is rippin more likely for stuff to break.

I run 275 bfg ta's on my 400 hp 340 and already have had to install a torque strap and bent a pinion snubber. I cant imagine drag radials or even slicks.

Thats when the u joints start to go lol

Well, my rear end is an 8 3/4 fully rebuilt with 742 posi carrier in it all rebuilt, with new bearings, seals, etc of course, n 323 gears in it, with small bolt set up, with steel wheels, with 255/60/r15's on them.
the tranny is a 727 newly rebuilt with a stage one shift kit in it,

The 383 up front is all brand new, with a healthy cam, 750 edelbrock carb, ported heads, comp springs, I am not sure about all the more specific compression and other numbers... :burnout:

SO, do you think 255/60/r15's are wide enough for this set up (just for street fun)??? I felt like they were barely enough when I ordered them.
I was gonna go 275's maybe with a little more backspace on the wheels, cuz I have enough room towards the offset springs...

Anyways, I surely can't imagine someone running the tiny tires they do with built 440's, super high horsepower strokers, or a Hemi up front... Isn't that just dangerous? Or inefficient?(This was my original question) :wack:
