I recently bought a set of 5 33X12.5" used tires from a friend of mine
and plan on putting them on my stock '76 CJ-5 rims in the near future.
I'm a little worried about the clearance for the back tires as far as
the leaf springs are concerned, width-wise. I'm not concerned about
the tires blowing off of the rims or anything like that. But then
again, I'm not the brightest bulb in the um... pack of bulbs.

A 12.50 is a bit too wide to go onto a 7" rim.

I'm starting to agree, An installer I spoke to said they would fall if
took a hard turn.

I currently have 10.5 on my 15x7 and was consider 275/60-15 ..

275/25.4 = 10.8 inches. Is this a correct conversion? and is 10.5
really 10.5? 275/60 look much fatter (since shorter) than 10.5x31
truck tires btw.

And for my other truck a 93 Ford 2wd ranger with stock rims 14x7, can
I get away with 255/60-14. 255 = 10.03 inches. I believe I've done
this before. Anybody doing this?

I can help but bring up the fact again, that when deflated, the inner
rim of most tires is pretty narrow and that tires seem to adhear the
ballon shape and might be safer that way as oppose the other extreme
of forcing the lip out with air alone.

Thanks *all* for the good info.

You came up with a neat millimeters to inches converter of dividing
by 25.4, but it didn't take into consideration the tire series
measurement, like the 275/60X15 is three inches less in height than the
31X10.50X15: http://www.1010tires.com/TireSizeCalculator.asp You might
familiarize yourself with tire terminology:
http://www.1010tires.com/tiretech.asp The series is a percentage of the
tire's width it has in height. Then maybe study the design of a rim:
http://www.off-road.com/jeep/wheel.htm See that rib on the rim the
tire's heel and toe must fit into, now imagine putting an incorrect size
tire on that rim.
