In an ideal world I am looking for 255/85/r16 AT tyres, however I am not sure if they exist - certainly can't seem to find any in the UK. So the current debate is 285 AT vs 255 MT. (Currently running 285 MT).
285 AT 'in theory' is likely to be less noisy than the 255 MT. But the 255 MT would have less surface area in contact with the road so would have some noise reduction, and also thinking the 255 might increase acceleration slightly (less surface area?). Does anybody have any experience with both tyre sizes? Any feedback with either? Would changing to 285 AT have a significant reduction in noise to the current MT (I don't really have anything to compare it too as when we bought the truck it had a right mix of road and AT tyres on, from what I remember it was quite loud even then). |

255/85/R16 BFG, KM2 MTR here, really happy, would go for the current KM3 when needed.
No problems at all or issues with noise, not good in snow or ice as expected and not to be driven rapid in very wet conditions but I’m really pleased with them. Off road they’ll go anywhere pretty much. They do very good miles as well, which is why the price is that bit more. Toyo are close though, people seem to be quite happy with those as well. |

Not sure I follow your logic at all about widths. For overlanding I'd have thought a common and easy to replace size would be ideal. 285 is arguably the poser tyre and unlikely to perform better anywhere over a more narrow tyre. Personally I'd probably go something like an XZL, very tough tyre and there is a reason they are used by the military. Although it would limit you to the 7.50 x 16 size. Which is a great performing size and you could always run with a 235/85 or 265/75 if you had too as they are all a similar diameter. |

It all depends where you are overlanding and the tyre availability.
Personally I'd go for 235s or 7.50s for ease of replacement. Mo The Land Rover 90 - Many are called, few are chosen. 50 Shades of Pennine Grey |

Where are you going? You don’t really want to be fitting an unusual size, you have to be able to get replacements where you are going. When we go to Africa in a couple of years I’m sticking with standard size.

I am with mo and chicken drumstick on this.
An AT will be quieter. Do you need MT? What are you aiming to do overland wise? Gravel tracks and camping a light duty AT would do it I wouldnt use MT s for overlanding. Noiser and use more fuel. I would also work with ready available sizes. A 235 of a good choice. 285s tend to be quite wide for some narrow rocky tracks and can pickup more sidewall damage.

Just got arguments sake which I'm sure Mr Drumstick will absolutely love but I find my 110 more sure footed off road on it's all terrains in 235 85 16 and an ATB in the rear no ABS or TC compared to my D2 that I used to have with 265 75 16 muds on which would slip alot more off road even with CDL TC and a rear ATB in was good when it really went but always seemed to slip a bit here and there. 110 Td5 Ex Utilities slowly converting into a pop top camper one day

I have extensively overlanded with both size, 255/85 BFG KM3 and 235/85 Cooper AT3.
My personal experience is that 98% of the time I was on tarmac or gravel roads. In terms of noise, driving agreement, fuel economy, mecanic sympathy, sticking to 235/85 is the way to go. For look, slight addtionnal ground clearance, true speedo reading go with the 255. Unfortunately no alternative in 255 AT in Europe but Ziarelli Cruiser retreaded tire. |

I’ve used 285 and 255 sizes. 255 is only available from Toyo and BFG in MT at the moment, from what I can see. 285 is manufactured by several companies and in both MT and AT. In terms of on road driving characteristics, there’s not an awful lot to differentiate a 255 and a 285 MT. Off road I’ve found 255 is preferable as they drop into wheel ruts and don’t float across the top. That’s not to say I’ve had problems with 285 ever.
255 is slightly taller than 285, by something like 0.2”, meaning it will raise the gearing and worsen acceleration. 285 also seems more ubiquitous if you need a sudden replacement.

It really is dependent on where you are going ! Down through Africa, central Asia eastern Russia is overlanding. You will find getting clean fuel, exotic oils and non standard tyre sizes very difficult.
Anywhere else isn't really overlanding and you will be able to get tyres, lube and fuel easily. HTH Mo The Land Rover 90 - Many are called, few are chosen. 50 Shades of Pennine Grey |

Just did 20 000km through Europe, Russia and Central Asia and back on 255/85R16, they are siped. Cruising at 85-95 fuel consumption is about 10.5-11L/100km.
The engine and wind noise is way louder than the tyres, I have a 300Tdi. Parts of the trip made Camel Trophy look like a parking lot driving exam... I see no point in fitting AT's these days. The Toyo MT's are superb. I used to run same size BFG KM2 but would not go back to them now. |
