| islandbound Member Date registered: Jun 2015 Location: PNW, USA Vehicle(s): landcrusier (RIP), e320 cdi, w113 280 SL, W460 Posts: 18 | 240g tires I got a 240g from my dads estate that was a 230G and someone transplanted a 240 diesel. I live a few states away do daily wrenching is more like quarterly. The G had been sitting for 10 years out of the elements. I rebuilt the lift pump, changed some fluids and got her licensed. The tires are bad and over sized, top this off they are at 4500ft elevation. Lets say this is the slowest vehicle I have driven. I need tires first I was thinking 235/85-16, eventually I will bring the G to sea level, however, after driving it should I go with 235/75-16? I am pretty certain it has 5:33's, I don't know if the trans (4sp) was replaced with the engine. The speedo is off the wrong direction, it reads faster than GPS speed and it has oversized tires. All this combined (unknown engine health, old diesel, oversize tires and elevation) and the G couldn't pull to 55MPH. It was about 100 degrees out and the temp did climb under load but nothing extreme and didn't reach the third of the 3 temperature marks. List for next visit Tires- Diesel purge, see if there is anything more that could be wrung out The fuel is old (at least 10yr) I have no way to dispose of old fuel and was thinking about syphoning half and filling with fresh fuel and repeat? She seems to smoke a little at idle and it could be injector smoke as it more white than blue. My thinking is first since the engine is very smooth, get a reasonable size tire. If that doesn't allow 55-60mph see what the other issues might be as I go through routine maint. Should I have any expectations of power with this combo? My thoughts are it should be close to my vanagon diesel westfalia I owned, aero of a toaster pushed by 48hp. It would do 60mph on the flat all day long. Edited by islandbound 6/25/2018 5:53 PM | ||

I failed to mention it is a cab so there is a little weight savings. If there is anyone on the Seattle area with a w460 I would love to check it out. | ||

hipine Date registered: Jul 2006 Location: US, CO, Bailey Vehicle(s): 460 1980 280GE w. 617A | RE: 240g tires Factory stock tire was 205/85-16. I run 235/85-16 with lower gears (mine are factory 280GE gears, 4.77 I think?) and the very fresh 617A (3L turbodiesel) that's now in the truck is just adequate. It actually prefers the 215/5s I run in winter. There's no way I'd run 235/85 on a stock 240D. It will be too much gearing and you won't be able to go up a hill in anything above 2nd gear. -Dave G. | ||

I failed to mention it is a cab so there is a little weight savings. If there is anyone on the Seattle area with a w460 I would love to check it out. From new the GD240 did 0-100 km/h in 45 seconds and top speed of 115 km/h. That converts into 0-62 mph and 71 mph. I have a diesel lwb that gives a reasonable pleasent driving experience. 0-100 in about 22 seconds. Top speed is 135 kmh. That takes 120 hp / 250 nm. 4.86 axles and a overdrive gearbox to do that. The G is a boxy and heavy vehicle, you need engine performance to overcome that. | ||

Thanks this helps, so I am thinking 235 75 16 are a better size. One thing is if I bring it home it would be at sea level and the highest speed limit is 55mph for about 10 miles around me. | ||

Johnny this is the time to speed that I have seen for a 79 Mercedes-Benz 240 GD Open-Top (man. 4) 0-20 mph (s):3.5 0-30 mph (s):6 0-40 mph (s):10.5 0-50 mph (s):16.1 0-60 mph (s):27.2 0-70 mph (s):53.1 If the 300gd has 8 more HP and higher gearing it is 4 seconds quicker to 60. I wonder what gain could be achieved replacing the mechincal fan with an electric ( main TIC ) mainly for a grin. Edited by islandbound 6/26/2018 11:10 AM | ||

| Fenalaar Elite Veteran Date registered: May 2006 Location: Narvik, Norway Vehicle(s): 2001 ML270CDI, Polaris 400L Big Boss Posts: 826  | RE: 240g tires The car will be more comfortable with 235/75R15. (Yeah, I know they look dinky...) The basic problem is that the engine has unsufficient torque for large tires. 235/75R15 works well on a 300GD with 4.77 axles. The 5.33 axles on the 240 helps, but then again it has even less torque than the 300, so it needs all the extra help it can get. You will rev quite high, but the engine can take it. It will have (barely) adequate accelleration, but not much top speed. Johan-Kr Edited by Fenalaar 6/26/2018 2:32 PM | ||

This size might be the best compromise tire size for your 240GD and your 0-60 expectations. | ||

I wonder what gain could be achieved replacing the mechincal fan with an electric ( main TIC ) mainly for a grin. Hmmnn.. that would be the first time I have seen these numbers for a GD240. To me that looks like the GD300 performance. I know that a open top swb is lighter, but would it really do that much for performance? | ||

One real advantage for a 235/75 is if you shread a tire a replacement should be easy to locate. ajl | ||
