(I mean, I agree with 10.5. I don't mean "10.5 x 2", or 21.)
I have seen narrower tyres do better than wide ones in mud too many times.

correct me if im wrong, wouldnt a wider tyre be more stable. as overall edge of tyre to edge of other tyre you are gonna lose 50mm in width.

what do you mean more stable? An extra inch each side isn't going to do much and the negatives of running a completley square contact patch outweigh the maybe once in a blue moon benefit of having a slightly wider track width.

you see everyone putting cruiser offset rims on patrol just for the wider track = bit more stability, same as 25mm wider tyres. also depends on what sort of driving your vehicle will be doing, my driving i would want something a bit more stable even the smallest amount.
can someone also explain the benefits of a narrower tyre to a wider one.

I can't explain it but I've seen narrower tyres go well in mud even when wider tyres with better tread struggled in the same spot.
The theory I heard was that the narrow ones sink through the soft stuff and bite into the hard stuff underneath it, while the wide ones "float" more. True or not? I don't know.

Very true my Dad told me when I was young and hes never wrong
Narrow mud
wide sand
Tryed to find 33 x 10.5 gave up and went 33 x 13.5

Maybe 10.5s were the way to go during world war 2
when they were under landrovers and jeeps and there wasent much rubber around becaause everyone was making bullets

Very likely, what with all the rubber bullets they defended our shores with.

ill try and explain why narrower tyres are better in soft conditions, ie: mud and sand.
when driving in soft sand, the sand mounds up in front of the tyres making it hard on the vehicle as if you are constantly trying to climb up a little hill.
the wider your tyres are the wider the mounds of sand are that you are pushing forward.
a narrow tyre with a tall sidewall will allow a nice long footprint when deflated and will give the best results in THESE conditions.
I run 37 inch { 930mm O.D ) tyres which are 10.5 inches (255mm) wide and they work great allround and i have 2 mates running 33/10.5/15 BFG muds.

I was running 750R16 on the 80 for awhile and on sand dunes they were awesome never would have expected it because they are pencil thin! I'm all for skinny tyres for all offroad situations and they get slightly better fuel economy over wider tyres.

Yup maybe but they look ghay as

It's ok you won't be able to see them from the bottom of the dune

yep because that's what;'s all about, how the 4wd looks. Don't worry about making it perform better just don't look ghay. If that's the case I think you're probably on the wrong website try a Jeep forum perhaps.

Silverstone make 10.5 wide 33's. But if you can fit 33x12.5 BFG muds, you can probably fit 35x10.5" Silverstone xtremes. (their sizing is a little out. The 35's are closer to 33's)
And they make the BFG muds look like all-terrains. Very cheap too.

Thanks mike but im after a mud terrain that will be used on the road mostly with a bit of mud work thrown in.. Ive got a set of simex that were my off road tyre but selling them as dont get away to use them anymore..
I will check out the maxxis and kelly range aswell but on thinking about it i might stick with what i know.. The BFG Muddies

maxxis dont make a 33/10.5x15....they make a 255/85x16 in the bigohrn which is 33.3x10.3x16
simex make alot of tall and narrow tyres as do Interco with their swamper brands....

i ran 34x10.5x16 tsl's
that cut deep in mud like simex or silverstone
but cut deep in sand like shovels at low speeds
or fluffy sand or foot down up hills
or taking off in sand
where my mate was in same kind of truck
but with 12.5 mt/r's didnt have same
problems in sand and they preformed good in mud
i run 13.5s wide now and no problems
on sand running road pressure.
i would say wider the better for sand as more
weight displaced over a greater area
saying that in the army there was a
formula for weight /wheelbase/terrain for tires
that why l/rovers had skinny s.a.t's
and different tires for sand/snow
and pull artillery around behind them
and still do since ww2
lol that might be why most other 4x4's have fat tires
to keep up with landies???
old horse n karts and vintage cars had skinny wheels
for mud roads and it seemed to work
but Imo stick with 12.5s for a bigger foot print in sand
10.5 in a bigger tire can run lower psi
to make them bag out to get a bigger foot print too

Pirelli Scorpion MUD 33/12.5R15
but they are 12.9"
and abit cheaper than bfg's
but wouldnt no how good they are compared to
bfg's

comparing a TSL to a MTR is a bit unfair. Tyre design will be the issue there more so than tyre size
Width is not what you want it is length and that is what happens when you air down your tyre, you lengthen the footprint

This has been the topic around many a camp fire, along with the " which tread pattern is best in sand " discussion, and its been proven again and again on beaches and dunes all over WA that narrow tyres are better in sand.
sometimes the exception to this rule is if you are running at road pressures.
driving in sand with narrow heavily treaded tyres may require a change in driving technique, with a little more finesse with the clutch and more restraint with the right pedal, for example, this tosser im unfortunate to know would dig himm self into holes quite regularly on the beach, but after fitting a 350 chev and 35/12.5/15's he's buried alot quicker and alot more often now.
The moral is you've got to learn to adjust your driving style to suit more than just your mood and doug's useless behind the wheel -- there its been said --
