It’s a real shame there isn’t greater choice of tyre in 255/85. 2007 110 TDCi Station Wagon XS

235/85 R16 are more readily available, which is why I prefer them over the 255's so if you destroy a tyre in the middle of no mans land, you've more chance of getting hold of one.

In the grand scheme of things the difference between 235/85, 255/85 and 265/75 are likely to make naff all difference. You're talking just over an inch difference in width and about 3/4" difference in ground clearance.
Realistically the tyre pressure and tread depth will make as much of a difference as the actual tyre size. The biggest impact it's likely to have is on turning circle depending on your wheel offset. For example a couple of weekends ago I was laning with some friends and my 110 has a better turning circle on the Zu alloys with 265/75R16s than most of the 90s. One thing to consider - which is why I'm unlikely to change away from 265s is that if you change tyre size it's not as convenient keeping the old ones as spares. I've got the best KM2 on the back door as a spare but there's also another three tyres in the barn which could be used as spares if need-be. [edit] I should have added that 3/4" is theoretical and in the real world you're likely to experience even less because the weight of the vehicle will obviously compress the bottom half of the tyre more. So in the grand scheme taking a subtly different line will make much more of a difference. Ed 82 Hotspur Sandringham 6x6 95 Defender 110 300Tdi |

I have run 255 85 16" BF Goodrich Mud Terrain for a couple of years now. Latest are the second generation ones which have great grip off road and reasonable manners on road. On the Tdci Defender I find they slightly up the gearing - at an indicated 60 mph I would actually be doing about 65 - 66. On 16 x 7 black modular they fill the wheel arches well without the need for wheel spacers of which I'm not a big fan.

I'll say it again as i think it's an important point that is lost here.
In reality a 255.85 is far superior for clearance off road than a 235.85 or 265.85. Over the last 15 years of running driving days the evidence for this is over whelmingly high. There were several examples again today of 265.75 km2 not making it where a 255.85 km2 did on like for like performance. Both on 90s. If you just want an mt looking tyre to fill the arches and look right the practical application of them may not hold that much weight. In which case consider 285.75. Bw, I run 235.85 ko2s in winter and take the vehicle with them on over the one with 255.85s km2s when there is snow,ice on the ground, compacted or not.

How much does the taller tyre raise the gearing? Is it noticeable. I really like the slow first gear crawl in low range on standard tyres and wouldn't want to spoil it. 2007 110 TDCi Station Wagon XS

It's a lot better, brings speedo to about bang on accuracy.
I've checked against GPS, and with 235 if the Speedo said 30 the GPS would say 27 - 28mph. With 255 if the speedo said 29 - 30 the gps would be about 30 - 31. I would say it's closer accuracy, the gearing is great and is especially good at higher speeds. After all you have low range too. I have also had great success with Dynabeads too, as has Blackwolf.

Thank you, your last para (quoted) actually sums up where I have come to in my reasoning, 235/85 ko2 for winter, 255/85 km2 or 3 at all other times. Have you any experience of the KM3 yet? The grown up reviewers seem to rate it highly, better on tarmac, snow and ice than the 2 by a considerable margin, which might make it an acceptable all-year tyre. The only downside of the 255/85 KMs in my view is that they are just too large to run tyre chains without suspension mods. |

I'd like to see that last picture with some weight on the 255/85 tyre.
Funnily enough everyone always posts size comparisons either with no weight on them with the smaller tyre (because usually they're upgrading). Ed 82 Hotspur Sandringham 6x6 95 Defender 110 300Tdi |

i use the 255.85 purely on a practical application for the clearance and currently run 90/110s fitted with
285.75KO2 255.85s KM2 265.75 KO2 235.85KO2 235.85Contis 265.45.20s Grabber so its not an 'upgrade pic' just for the sake of it for my usage, but i follow your logic. BW - sorry i dont have any KM3s yet but have heard similar - plus quieter on road. Cheers James 110 XS Utility 130 Puma Station wagon/camper (in the making) 90 Puma Hardtop |
