The main reason for this is to see what increase there is in fuel economy. Currently averaging between 22.9Mpg to 24.2 Mpg tank by tank (26.8Mpg on a run up to Manchester) so as I am doing the same run again this weekend to see my daughter I will see that the difference in fuel economy is.....

With the rack on at those speeds it did about 12-13mpg and the wind noise was horrific, hence me upsetting Dave and taking the rack off ;) At 70 and below it's much more economical. I run on 19" Pirelli ATR's and to be honest, I didn't notice any difference in economy between those and the road tyres it came on, nor was there an increase in road noise from the tyres. I've never bothered going back to road tyres since, especially when the ATR's lasted 50k miles and the road tyres only lasted 15k, the cost difference wasn't worth it. Now I have all the kit back on it here in Oz, bearing in mind the speed limits are lower so I'm generally trundling at 62mph (100km/h, snooooooze) or just round town at 80km/h, it's doing 17.5mpg. If I bimble along without using the cruise control I can get better than that, but boredom usually sets in. I'm getting about 450km's to a tank of fuel at the moment, so it's not too bad but if & when we do start using it for travelling I'll likely have to fit a longrange tank under the back and use my spare wheel brackets on the roofrack. I'm told the snorkel makes a difference to economy as well, but I really couldn't be arsed unsticking it from the wing and driving around with holes in the side as well for the tiny benefit I may have gained. Let's be honest here, it's a V8 petrol in a 2.7tonne barn on wheels, so it's never going to sip fuel like a vicar sips tea, it's more of a scotsman in a McEwans brewery. Besides, the V8 sounds great through the snorkel with the window down a bit :cool: BV55 YZE, Fleet No 19 - Thailand 2006 Now registered as YZE 481 in Melbourne, Oztralia.

Watch this space..... This is a diesel rather than a petrol v8 right? I have a new set of 19" rims together with Pirelli Scorpions and it has certainly saved a couple of MPGs in petrol on the urban and extra-urban (avaraging now around 16mpg urban and 18mpg on the motorway using around 80mph. Off to the Lake District this weekend so will see how we do on the 550 mile round trip. (I have debated doing other things, but then it is a G4 and the reason to buy it, is to have all the toys - snorkel, roof with lights and ladder, and possibly even the Goodyear MTRs... That said, when i have saved up £2k, I think I will convert to LPG)

Group: G4 Member Posts: 131, Visits: 3.6K	Hi When I had that Disco 3 I only used Shell or BP diesel and regularly got 27- 28mpg I always had Mtr tyres and cruised on motorways with needle on 70mph. The tyres you have fitted must be much wider than 255 which will cause more drag and increase fuel consumption go back to 255/ 55/ 19. I am getting same fuel consumption as you with mt RRS TDV8. 23-24.5 local and up to 26.7 on motorway. paul (sandy)

Group: G4 Club Member Posts: 33, Visits: 158	Must admit I am slowly coming to the conclusion that there is not that great a difference between the Goodyear MTRs that the G4 comes with and the Pirelli Scorpions that I have recently fitted, albeit the initial belief was that I was saving significantly on MPG and Road noise. (maybe I am driving the vehicle harder now!) More importantly, as noted by some recently, the G4 looks better with original tyres that "mean business". . . So may get a bit more wear from the Scorpions before putting them back on eBAY and reverting back to the authentic look. BTW: In this months, LRO Magazine it also has an article on tyres / rims and suggests Show / Specialist cars stick with the original! The money from the tyres may go some way towards the new suspension compressor that is required rather soon!
