Speedometers are required by law to read -0/+10%, ie they can over-read up to 10% but must never under-read at all. Since it would be prohibitively expensive to make a traditional speedo that met this tolerance they are traditionally made intentionally to over-read by 5%, +/-5%. This meets the spec and is easy to do. So most will indicate a higher speed than you are doing.

65mph with the 2.2 tdci, it is just happy there, my ears are ok, mechanical sympathy in tact. The 300tdi is happiest at 50-55. I’ve got no sound deadening in either, no remap or different gear ratios, they are bog standard.

For what it's worth, 2003 TD5 90xs. On our trips to Cornwall from Merseyside we used to get just passed Exeter and needed to top up from a full tank to continue down to just outside Truro, that was over 12 years ago when it had not even done 10,000 miles, now at just over 80,000, we can get all the way down there and still have enough fuel to reach a Shell station 5/7miles away. We found best speed for fuel consumption to stick with the Lorries, but can become a bit boring, every now and then we speed up to 65 for a bit and occasionally shoot up to 70 just to overtake, last 3 years have gotten there with fuel to spare on a full tank, if we stuck at 65 all the way, we would need to top up. Hope this helped. Regards
Dennis. |

My 300 tdi ht 110, with roof rack, 235's and a pump tweak, will get up to indicated 95 ' in favourable conditions, twice in 12 years!' but I mainly cruise at an indicated 62mph. I find at 62 the motor is happily buzzing away, with enough revs to keep on top of it when hills come along, but at 55 it's also happy if there are no hills, on a run from Devon to Kent with a tail wind, best mpg was around 35mpg, and this was in the 65mph plus bracket, but usually avg 28-30

Forgot to say, yes to driving with the lorries, for various reasons.
1) they create a significant draft, which does help. 2) they sit high up, so can often see what' s coming up, and less likely to brake hard. 3) they travel at a constant speed, for hours, and this is good for economy 4) if you are behind one, then every time you put your foot down to overtake, you're using xtra fuel, for no real reason, because there will always be another one to overtake in a few mins. Defenders have been ' modernised' with the 6 sp/ tdci combo, but are still agricultural vehicles, and really should be driven/ treated as such imo. |

I just checked my tyres which are all Yokohama Geolandar AT-D “M+S” tyres bought in the last few years. Size is 265/75/R16 and the fronts have 55PSI stamped on them and the rears nothing re:PSI on them. 55PSI seems a lot as, with power steering on the XS model, it’s already very sensitive to steering wheel adjustment. I’m currently running them at 45PSI, to see how it handles. It’s only used on roads and decent quality farm tracks.
For my long motorway journey north should I up the pressures to 55PSI? Thanks —————————— 2004 110 TD5 |

I am genuinely shocked everyone runs their tyres sooo high!
My mechanic specialises in Land Rovers - Specifically Older LR upto the TD5 model and nothing newer... He has had his garage for a very long time - I do believe he even mentioned it was his dads before... So I trust what he says when he says to put 36psi front and 38psi back... im shocked. My truck handles great actually - sticks to the corners, firm pull away and braking - the wheels have locked under very heavy breaking... Im running BFG AT KO2 I am wondering now though... How does all your trucks handle being pumped to 55psi? Regards Adam Loving The Duchess The Defender 110 TD5 XS My Defender story - http://www.defender2.net/forum/topic64005.html |

36 front and rear on mine. I wouldn’t run higher tyre pressure for fuel economy.

Land Rover recommend 48psi in the rear tyres of the 110 for general use.
There must be a reason why this is the case, personally l find that the ride is actually worse at low pressures, as the bouncing from the tyres conflicts with suspension damping. |

interesting, perhaps ill top them up and see how they feel for a while..
I have scorpion suspension and terrafirma shocks on the rear, don't know if that makes a difference!! Regards Adam Loving The Duchess The Defender 110 TD5 XS My Defender story - http://www.defender2.net/forum/topic64005.html |

My suggested increase. In psi was for economy not comfort. If your not sure and have to ask your garage what pressure to run at then you are probably best leaving them at lr recommended pressures. Cheers

With stock tyres id run stock pressure, but not running stock, id queried what might be best, and thought id best to ask my mechanic who has experience with stuff.
its interesting though, those running 55psi - when someone stated that stock was 48psi??!!?! Either ither - my truck runs sweet!  Regards
