H78 x 15 rims

i'm going to use the original wht steel rims
this winter.
what are the largest tires that can be mounted
on this rim size?
thanks
dave

 

H78-15 is the size of the tire, so the rim should be 5" wide. Most tire manufacturers will suggest a rim size for a specific tire in their list of specifications. Pick the brand of tire and look on their web page for specs.

 

I've been using 235's with no problems,,,,

 

i'm pretty ignorant about sizes etc.
i guess i want the biggest tire size
for this rim to run in winter.

i drive mainly in town.
pop = 1700
usually never get over 40mph

Oops - stock rim size is 5.5" x 15", not 5x15. Anything listed for a 6" wide rim should be fine.

 

thanks tim
i'll take a peek at the
4wd mag

If you go to www.tirerack.com, pick "tire size", enter 235 75 15, and check all terrain and off-road, you'll get a few dozen options to look at. A 215 75 15 will be a little shorter and narrower, and a 30x9.5 15 will be a little taller and wider. I've seen larger tires on stock 6" rims, but the sidewalls angle in a lot, likely too much. The 215 75 15 is the usual recommendation for that rim size, from my quick look at the listings.

 

Dave, I run those same wheels on mine. I put BFG KO AT's, 235-75R15 on & it looks right plus drives great on the road & great off road. JMTC

 

hi tim
do you have those tires on the jeep in your avatar?
if not, could you post a pic of what your jeep looks like
with them on?
thanks

They are. For more pics got to the thread "Need help figuring out my 73 CJ5" and you will see some better photos that you can enlarge.

 

Just removed a ratty old set of 32x11.50's from stock steel 15x6 Jeep wheels that my Dad had, so obviously larger tires will "fit" on narrow rims, but it's not really recommended.

 

hello mr pathkiller!!
here is a picture of my original 77' CJ5 rims.
i bought them from the gentleman who
now owns my jeep!!
i plan to put the biggest tires on these rims
that is possible.
i only plan to drive this jeep around town
and to use them only during the winter.
