Mud terrain tyres 255/85 vs 235/85

I am looking to buy new tyres to my Defender 110 300 Tdi. I have a set of BFG A/T 265/75/16 currently on my Td5, the performance of these have led me to the choice of BFG M/T KM2 for my 300 Tdi.
However, I am unsure of which dimension to choose. I am currently looking at either the standard 235/85/16 or the slightly higher 255/85/16 to mount on a set of modulars. I have read a lot of threads that the 255 sort of are ok on a non-lifted Defender (very little rubbing), but would preferably be coupled with a small lift.
I have searched all over internet for good pictures showing the difference between the two without much success. I would be very greatful for any posted photos of these dimensions fitted onto a Defender (preferably the KM2, but KM1 would look similar I am sure).
Even similar dimensions of other manufacturers would be of value to judge for myself what size would be the best.

BFG = punctures

go for kumaho or coopers.

Not quite what you asked for but have a look here

Custom rims, wheel tire packages for your ride - RIMSnTIRES.com

just to change the mood slightly

(BFG are unstoppable by the way! (this ought to start a debate))

i need some 35/12.5/15 KM2 muds if anyone knows of any. I can get hold of a set of five but can only afford two and i only need two. if anyone else wants to go for three or maybe individual spares maybe we could chip in to get the set. (£600 for five in good condition)

What I am looking for is just pictures of Defenders with the above mentioned tyres. I have not been able to find images on the internet that both show these and tell what dimensions they are. It's always either or, unfortunately.

Just spent three weeks off road in the stony hammada of Sahara with BFG A/T's over thorny desert bushes and sharp rocks all day, not a single issue despite the tyres used are in less than perfect condition. I was quite impressed as I expected punctures...

B3aker has 255/85R16 on his 110. Not lifted. Contact him for more info.

I would go for 265/75 16 Cooper STT's I am on my second set now after by BFGs and they are excellent in the wet and mud, £400 for four fitted at National Tyres and I sold my old ones with around 4mm left on them on Ebay

Dad runs the old style BFGs (KM1) in 255 85 r16 on his 90. they up the gearing a nice ammount.

They also stand exactly the same height as my 285 65 r 16 coopers (33.3 inches)

Thanks for the photos Boris, exactly what I was looking for!

Are you going to compete in RTV style trials at all?

The narrower 235 will offer more lock and a tighter turning circle.

Not sure I can help with both tyre sizes, but these are what I can do:

255/65R16 ~1" lift



31.10.50R15 ~1" lift


33.11.50R15 (290/90R15 equivalent) ~ 1" lift





235/85R16 stock height:




32.9.50 16's


7.50's

Amazingly good post! op2:

I have been running 255/85s for a while now. the new KM2s are awesome. I would either go 265/75 or these 255/85s. If your leaving it stock 265, if you want to raise it an inch or more 255. I would leave 235s alone. The 255s give you a good extra height and space under the diff. It all depends what you want it for... see my site for photos
