John

Also as tyre pressure lowers the difference in rolling radius between the belts and the tread blocks results in more flex and scrubbing of the tread blocks as they enter and leave the contact patch.

The less tread on the tyre, the smaller this difference and the smaller the change in rolling resistance.

Well that's my story anyway.

No problem Dizza, just pm me your email address & I will send you a copy. It is a 3.0 MB JPEG, taken on my point & shoot Panasonic.

...Noticed the new tyres on a bus i drove today... 225/90-Rxxx Looks like 100% is or was the standard aspect ratio for low speed buses and trucks... but the 10 percentage points / 'Low Profile' did'nt give any significant change in hill-climbing ability.

Or the lack of it...

The other comment I meant to make before is... the higher ratios give softer/quieter ride, but the lower ones give more 'handling' / harshness and noise. Which means in theory, your standard tyres are 'nicer' riding - part of the Range Rover mystique...


Pic looks very nice indeed...

Well here is a blast from the past. Whilst spring cleaning the shed I came across my wife's old Compaq Portable computer vintage Feb 1987 or so. This took me back to 1988 in Singapore where we used a not so portable Compaq to perform FADEC fault dumps on JT9D & PW4000 EEC's. So set it up for a Rangie fault dump:





Seems to suffer the same problems the one at work did.

Now what to do with it, as we are trying to declutter but its been in the family a long time. Wonder what happened to my old Apple 2C Plus?

Phil, many thanks for this - excellent, and I'm about to do the mod.
If I have got my understaning of your measurements right, the centreline of the new location for the right angled bracket for the upper tailgate swivel point on the door opening (near your little magnet) is about 50 mm above the two side locking mechanism bolts for the bottom door. Could you please confirm? If I'm not making sesnse, I'll send a diagram.
Cheers Gavin
