in the detail i did,nt see
after getting gav to look into diff gearing
looking in to aftermarket overdrive ect
i went for wider wheels so i can use a bigger profile tire
to gear my G up a bit and maybe get better MPG
TODAY received the shipping document by email from graz
the wheels alone weigh 130kg without the tires
i don,t think this is going to help MPG at all
that is more than a tank full of diesel
on the + side they will look dam good
Just going into training before you buy your V8?

A pallet and packaging may be part of that....also what do your existing wheels weigh?
Might not be such a big difference.
On another note, what speed and what rpm are you currently running, for you wanting to bring it down?
Lower rpm doesn't always mean more economical.
Hi Adrian, I've gone up a tyre size and consumption has dropped from 400 miles /88 liters to 335 miles /88 liters. Not sure what my wheels weigh but 650 kilos including a spare dues sound quite a lot. Let us know how you get on. On the bright side those Hutchinsons look great. Once I see a pic of your G I may well get on to the guys at S-tec.
Good luck
Kevin

Granny eggs sucking teaching, all that aside, is that with mileage corrected, as bigger tyres register less on the trip meter due to less revolutions for same distance travelled? Seems a substantial difference for one size up.

24 is nothing to be ashamed of. The 617a is a brilliant engine, but from an age when diesel knowledge and technology in terms of fuel efficiency was just not quite in the same league as the 601/602/603 series. On the plus side, it is the most robust of them all. Either way, yes you should be able to better 24 by changing tyre size. The most fuel efficient diesel is doing it's speed at half-throttle with rpm at torque peak, or just above, so keep that in mind. The 4-speed is just about the sweetest changing manual MB ever made. Also the only manual you could get from factory behind one of the old 116/117 V8's. So I'd definitely keep the drive train as it is. Maybe scrutinise your EGT's and play with adjustments. Tyre size is something you could change, so quite right you're busy with that. 3100 at 60 is a bit too high, even considering the 5k capability of the 617(a). By comparison, my 4-speed 460 SWB with a standard 617 (book thrown away, tuned by "ear") would quite happily sit at 70 all day long with 255/75-15's. That's 5.84% bigger in diameter than what you have there. Driver behaviour/habits/preferences are the biggest variables, together with individual engine characteristics. Me in your position, I'd get a few different size sets of part worn tyres off ebay to experiment with. Maybe 245/70-16 and 265/75-16. Spend a bit of time with each and see what you think before making a final purchase of decent tyres. Just remember to use a GPS for speed and correct distance travelled by adding the percentage of tyre size increase, as your speedo and trip meter only counts wheel rotations and not actual speed or distance.
As for the weight of things, weigh the wheels when they arrive. TNT for example, as standard provide insurance at £xxx per kilogram, so quite often, the cheapest way to get the right insurance level is to book a higher weight.
For reference a standard 16x6 steel wheel with a fairly worn 235/85-16 Grizzly Claw (heavy tyre), weighs 37kg.
Hope the above helps
before and after + a nice comment from GRAZ
Your car looks awesome with the Hutchinson rims!
All best

I do like the look of those....do they affect performance?
Spider1V
what was the cost of the new wheels? they look much better suited to the G than the others...
Im still pondering options...
John
hi joe for the better as i can fit bigger rubber which has dropped the RPM
SO before 21mpg now 24mpg
THE ONLY down side you need to press the brake peddle a bit harder
but fantastic OFF ROAD
