Substitute for 31x9.5R15
 

Hi all,

'been lurking around here for a few months, (just to make sure I
wouldn't ask the stupid question everyone else asks !) and already got
a lot of info.

I am looking to get new AT-style tires for my '03TJ. I do not want to
put in a lift on it until the waranty is out, so I am limited to what
can fit on it stock (more or less). I know that I could fit 31x10.5,
but I do not want tires that wide. 31x9.5 would be perfect, but I did
not find it in any AT tire. After a little looking, I realized that
235/85R16 would be a good substitute. They work out to about 31.5x9.5.
I would install a 1" body lift, and these should fit just fine. These
tires have an E load rating or 3000# per tire, while my TJ weights
about 4000#. I am wondering if there is any downside to using tires
with that much extra load capacity ? Any other thing I should be
considering ?

Thank yall.

Your TJ can take 31x10.50s without any lift. There is a small chance that
they will rub during full lock turns, like a Uturn, but this is easily
corrected by removing the steering stop bolts and installing a washer or two
then putting them back in.

Alan,

Just wondering why you prefer a 9.5" wide tire over a 10.5" wide tire?

See the load ratings for all the BFG AT sizes here:

I have never seen the load rating brought up before. Is this something that
really needs to be worried about? I mean my tires will hold more than my
jeep weighs, is there any harm in than? Not trying to start a war, just
interested. Has anyone else considered the load rating when purchasing an
off-road tire for a jeep before?

No expert here but I would think the higher load rating would ride
rougher on the street, but might have more sidewall strength for
airing down and running the rocks.

I'm curious as to your opinion for an alternative to the BFG 33x9.5x15
M/T. Unfortunately they are no longer available.
One tire mechanic told me it was because they keep 'flying apart'

The smallest now available is the 33x10.5 M/T and it has a 10.5" wide
tread as you mentioned.

I ended up getting a set of Goodyear 32x11.5 MTRs.
Nice tires. I'd recommend them but then I park my CJ-7 in the winter.
