235.85.16 is just slightly larger than a 7.50 but if you are
wanting wider? 265.75.16 is your boy..... You will need 7" wide
rims though!!

Tyre sizes are supposed to be standardized however different
makes end up at very different diameters and hights.
750/16 tyres range from 30 inches tall to 33 inch tall. The
tallest I have found are the Michelin XCL coming in at just a
fraction under 33inches. Yet require just a standard landy lwb
rim.
235/85/16 are the metric version of a 750/16
i have just fitted 8.25/16 michelin xzl tyres to my LWB they are
mounted on wolf rims and come in at just under 34 inch tall.
Go to a tyre warehouse armed with a tape measure. Even when
using the american system for tyre sizes the hight is often over
exagerated with "35 inch" tyres often measuring at 33 inches in
the real world.

7.50 R16 tyres are +/- 7.5 inches across the tread.
235 section tyres are +/- 235mm across the tread (9.25 inches),
so whilst in diameter a 235/85 is close to a 7.50, it is quite a
bit wider.

If the real world matched the theoretical world I would agree
with the last post. But when you start to measure older 750
tyres you find many are wider and often 235s are smaller than
advertised.
So if you want a specific size use a tape measure on the tyre
and wheel combo you intend to use.

That's true for rolling radius but not width as Doug says.
Whilst variety exists in the real world I've not yet seen a
235/85R16 from any manufacturer where the published tech data
approves fitment on a 5.5J rim. I've seen 235s that look so
narrow you'd bet money on them being 750s (remoulded shite to be
fair) but that is at the tread, the carcass must be wider at the
beads. There is no true metric equivalent of a 750 (it would be
something like a 190/100R16) although Mich do make a 255/100R16
which is a direct metric equivalent of a 900.

I love tyres I do :rolleye0012:
I run said Michelin 255.100.16 xzl flavour the old pattern same
as the 7.50 & 8.25 xzl... They are the tallest 9.00, stand 37"
xcl 9.00 stand 36" as I had a set and the good old 9.00 bar
grips stand around 33/34" ??? so as usual nothing can be taken
for granted when it comes to tyre size make and model!!
The question at the top, next metric size up from a 7.50 16 is
answered... A 235.85.16 very near same height but slightly wider
than a 7.50 also needs a minimum 6" wide rim, 265.75.16 very
near same height as 7.50 but wider than a 235, also needs 7"
wide rim.. 285.75.16 taller, around 33" also wider needs a 8"
wide rim, this is a big tyre, you will need to look at a chassis
lift +2" minimum, parabolic springs etc will get you on your
way, still may catch bits n bobs..
Hope this helps to answer your question? Having run just about
most tyre size and model, I would say you can't beat a Michelin
7.50 for a good alrounder for both SWB & LWB models, Michelin do
stand a little taller than most and unbeatable for quality..
I personally run Michelin xzl pattern my LWB models, 825.16 &
9.00.16/255.100.16 but I run 235.85.16 BFG AT's on my SWB.....
All are mounted on 6.5" wide rims..
Cheers
Chris..

allot of the widths v.s aspect ratio tend to include the
sipes/shoulders of the tyre which aren't touching the road and
look (visibly atleast) to be part of the sidewall

Me too :smilewide:
I've got a bit of variety on mine as well. 7.50R16 Mich XZYs on
the 2a 109 (5.5J rims), 255/85R16 BFG MTs on the 88 (6.5J rims)
and 235/85R16 Cooper Discoverer STTs on the ambulance (6.5J
rims). I'm a real fan of 255/85R16s as like 9.00s they're
approved for a 6.5J rim and are usefully bigger than 235s. I had
rear tub rubbing with the 2+1 leaf parabolics off road when
articulating but the 4 leaf jobbies have sorted that.
To be fair the Coopers have taken far more abuse off road in the
US with a fat old ambulance sat on them without a hint of a
problem, I went that route as one of the mags about 10 years ago
did a review and found them more resistant than pretty much
anything else to punctures from sharp rocks and stone. Most of
the US stuff is on that surface.

I have the 235 on my SWB and they are awful bulbous things. I
don't think they look right. If mine are 6.5 rims - then what's
the next best option - 205 ?
