If you live in town and do a lot of school runs/ shopping trips when the engine doesn’t get up to temperature then you will suffer badly in the mpg stakes, putting the tyres to higher pressures for town driving won’t have any benefit. You do have an Expedition Roof Rack that will not be helping things but effect of that below motorway speeds will be tiny
Basis one and a half tanks full of diesel my consumption has reduced slightly since fitting Duratracs! I listed this in another thread
I don’t commute and in the current tank I have done one trip right into the centre of Glasgow which involves quite a lot of stop/start traffic light Grand Prix stuff. I look that one up and see what it worked out at but it is reliant on the LR trip computer - something not considered to be hugely accurate. Here are screen shots for the only trip I’ve done that in any way resembles a commuting trip, into town mid morning but returning at school coming out time (Scottish schools had just resumed full time education that week) Click image to enlarge Click image to enlarge The vast majority of my trips are like this one, from home to the nearest supermarket, done on the Duratrac tyres. I have no complaints about the mpg which is all most the same trip in my last RRS SDv6 HSE that got around 32 all the time on the same trip but as high as 40 mpg stuck at 50 behind caravans and tractors with no opportunity to overtake Click image to enlarge Here is the last few refuel numbers for my last RRS SDv6 3 litre HSE Dynsmic running into Continental All Season tyres Click image to enlarge And just to show what is possible with a PHEV ruing electric mode as much as possible with a max electric range of 19 miles in real world driving in the Countryman§an PHEV.. I would have loved to refuelled on June 12 when I parted exchanged the Countryman for the Defender - I had used about 1/4 of a tank of petrol and done around 200 miles during lock down but mostly short purely electric driving to the Co-op 5 miles away in the next village. I try not to hand over cars with a full tank of fuel though.........

Now gone - old faithful, no mechanical issues whatsoever ever but the leaks and rattles all over the place won’t be missed! |

Got my best fuel figure so far today, stuck behind a long line of tractors, trucks and oldies frightened to overtake all stuck for 12 miles behind a car towing a caravan at 40mph......... even through villages with a 30 limit...... I suspect the tow car driver didn’t know what the mirror things are for on his driver’s door.....
not sure if is cheating but I didn’t leave from home and at the departure place the engine was already fully warmed up but having said that the first 8 miles were up hill and down dale and one set of traffic lights at a road works where auto stop/start cut in on the red light. Outside temperature was 16c light tailwind and running on Duratrac tyres Even allowing the “LR Trip Commuter optimism” factor of 10% it’s still not a bad figure.

There is a tyre comparison video for off-road tyres on. We Defender on the Off-Road Adventures YouTube channel - the presenter reckons that the Duratracs increase the fuel consumption by 2-4mpg. I have to say that my consumption is unchanged since changing to Duratracs.
Something else I hadn’t picked up from the configurator that he points out is that there are two options of off road tyre offered as OEM factory/ dealer fits - the Wrangler Adventurer and through the dealership rather than (as I read it) factory fitted there are Duratracs as the “professional” off-road type option. Also interesting to see how many more aggressively treaded tyres are homologated by LR for the New Defender when you look on the tyre supplier websites.

Managed to get 495 out a full tank and all i did was put the tyres pressure up to 40psi front and 45psi at the back. I will see how the next tank does.
