Wheel sizes and big tyres
DIR By: Snailer
Date: January 8, 2012, 4:34 am
---------------------------------------------------------
In the olden days there was a thread that had a picture of a
standard wheel and tyre and another that someone had fitted, one
thing comes to mind, it could have been in a green laning
thread?
I am not ready to swap the tyres just yet but wanted to start
looking out now if I needed bigger wheels first, steel of
course, none of that fancy alloy.
What looked impressive is that the new rolling radius was about
2 inches greater and this means greater clearance for green
lanes and better top speed and having no overdrive this would be
a great help.

I've got 235/85 Michelin XZL tyres on forward control/130/one
ton/whatever rims, and I'm very pleased with them so far! I was
told you can put them on standard rims, but it pinches them and
isn't recommended. But I don't know for sure!

does this work?
I'm now the owner of a 1975 SIII which, other than a
freewheeling hubs, overdrive and a second 2.25 petrol engine is
looking reasonably unchanged. What's stopping me from putting
BFG 235/85 R16s on it? I've got 4 new ones at cost from a mate
but I've had a chat with a local tyre fitter who said they'll
rub on the arches. My mate's got them on his SI and they work
OK.
I've trawled through the various debates from earlier this month
that ended up getting slightly 'off-track', and I've had chats
with other 4x4 owners of various vehicles and ended up
disappearing up my own arsehole with differing opinions.
I know there's no simple answer, but anything vaguely definitive
would be appreciated.
I a newbie to land rover owning but I've already decided that I
don't want to continue to be the wanker with SLTs getting stuck
all the time and I'm determined to get them fitted
somehow....any advice and ideas would be great....
Oh, and I've also got no broadband at the moment so I've got to
rely on somone else's router, so I might not be able to get back
online again until tomorrow....just in case you think I'm being
rude if I can't get back to you straight away. Cheers

235x85x16 with LWB rims, no problems. You may need to adjust the
lock stops a little to stop them from catching the springs, but
other than than that, they will not catch the arches.
What's stopping me from putting BFG 235/85 R16s on it?
Nothing, other than standard 109 rims are 5.5J and BFG recommend
a rim width of 6.0J to 7.5J for this size. 6.5J ex-MOD rims are
cheap enough from Vass/Withams, worth getting a set IMHO and do
it properly. Added bonus is you won't have to adjust the
steering lock stops, at least I didn't have to with 235s on
these rims.

I'm going through the same dilemma with my S1. I have some 1 ton
rims from Vass currently fitted with 7.50 x 16 Michelin XZLs
which are tubed. Can I fit tubes to BFG 235/85s? if not, what
tubed tyres are available in that size that have a less
aggressive tread than the Michelins?
Sorry if you think I've highjacked the thread, but it seems to
be relevant.

Yes you can, using 7.50 tubes, it'll be fine.

Hi there. Thanks for the advice. Much appreciated. So, bearing
in mind I have 205/R16s on my SWB SIII a the moment, you reckon
I could get some 6.5J rims from Vass, get the 285s put on them
and do a straight swap? I've checked and Vass are doing the 1
tonne 6.5J 16s for £20 ex VAT and the Wolfs for £30. Are the
Wolfs that much better and if so why? There seems to be
suggestions that you might be able to get away without tubes
with them.
Any more options/suggestions would be really useful thanks.

I've got 235/70/16 on mine and they look right in the wheel
arches and haven't yet caught the wing or springs. But they are
on gay wheels (apparently)
They have also helped to chase a boingy with BFG MT's up a steep
muddy hill.

As far as I'm aware the Wolf takes a tubeless tyre which gives
you much greater choice when it comes to what tyres to fit and
less chance of punctures. The downside is that they're made of
thicker steel and require a longer wheel stud.
I am aware that many people have fitted them without changing
the wheel studs, but a friend locally failed the MOT last year
because the tester felt that there wasn't enough thread wound
onto the wheel nut.

I presume this is a typo and you meant 235s, if so then yes
they'll go straight on.
If you are considering Wolf rims then be advised there are two
types with two part numbers, a tube type rim ANR5593 and a
tubeless rim ANR4583. The latter are stamped ANR4583 TUBELESS.
<edit> Good link there from Nugget.

My SWB S2 has always had 235/85 R16's on, on LWB rims. never
been a problem. They are the nearest metric equivilant to the
750's it came with from the factory.
235/85's are a wee bit wider than 750's but not so much as to
cause a problem. If you need to tweek the lock-stops a bit, no
great hardship.

Having had issues recently with tubes puncturing all the time
I've now decided to fit the right tube for the tyre 'cos I'm fed
up with it.
HTML http://www.tyre-rite.co.uk/searchresult_innertubes.aspx?CategoryID=168<br
/>
This place is good, a 7.50x16 tube is listed as £8.68 and a
235/85/16 as £12.72 so I presume it must be wider.
The difference between the two isn't so much the width its the
lenght/depth of the tyre/tube that may make it more expensive.
A 7.50x16 circumference is about 755mm (if the aspect ratio is
85%) , a 235/85/16 is 806mm so its a small difference ( 6%).
A 235/70/16 is 735mm round and so is only about -2.6% different.
(+/- 2.5% is acceptable for most old school speedos)
Bored yet?
So the '70' may be closer to the 7.50's but an '85' will make
you go a bit quicker for every turn of the wheel and will
probably look cooler!
( if anyone has driven a self propelled sprayer they will know
how this can be shown on an exagerated scale, you have to re
programme the computer when changing from floaters to row crops
and the machine goes significanlty quicker on the row crops
because they have a much bigger circumference)
granny/eggs/suck Sorry!

This has been covered at great depth on here in the past and at
the risk of raking up past arguments I shall say what I've said
before. A 235/85R16 is the nearest metric equivalent in terms of
height to a 750 but not width. 235mm equals 9¼", considerably
wider than 7½".
The tyre specs I've seen for 235s (Coopers/Mich/BFG) all state
5.5J is too narrow a rim for safe use of 235s and I figure they
know better than I do!

The old money aspect ratio is subject to much debate and
generally accepted as 100% so a 7.50 should be 7½ wide and 7½
tall. I did find a very detailed site on the web a while back
and that said the correct figure is 93% so close to the accepted
100%.

I never knew that the aspect ratio of a 7.50 was 93/100%.
So, if it is 93%, the circumference of a 7.5 wide x 7.5 tall on
16'' rim is going to be 2387mm.
A 235/70/16 is 2310mm
and a 235/85/16 is 2531mm
But if you want to be closer a 255/70/16 is 2396mm round, but
unless youv'e got RR front axle its really going to hamper the
old steering.
It all depends on how much you want to affect the gearing IMHO
( if the aspect ratio of a 7.50 is 100% then the circumference
is going to be somewhere between the 235/70 and the 235/85.)
Oh shit its a bloody minefield!! I'm out.
I get on better talking ballistics and trust me that is even
more of a mine field!

So then if you are using 5.5j rims you would need to shod them
with 215/85/16 in new money? Be about the same circ, and
slightly wider at 8.5inches.
Bollocks ,i'm really out now.
(fingers crossed i haven't stuffed up the forum)

Here you go:
7.50 on left, 235/85 on right, same tread for comparison.

Yeah, 235/85 are the same height but a bit wider. Didn't realise
they were 1 3/4" wider, they don't look it in reality, I have
series with both on and you have to look at them both quite
closely to notice one's a bit wider.
There is no problem with 235/85's on LWB rims, that's what
defenders have always had? I've used 235's on my series for as
long as I've had them. You can even put 265's on LWB rims I'm
told.

Nope, Defenders have 7.50R16 on 5.5J (now tubeless) steel rims
as standard. At least they did until very recently, the 58 plate
boingy hicap that our fencing contractor uses does. Those that
run 235s or wider have an alloy wheel option or theoretically
Wolf rims although in practice I don't think that is a published
option. Wolf rims tend to be shod with 7.50R16s ex-factory.
I'm not saying that running 235s on a 5.5J rim is dangerous as
many people have done it with no problems. My point is if the
tyre manufacturers state a certain rim specification for use
with a certain tyre then they must do so for a reason. Certainly
a 265 is far too wide for a 5.5J rim, it's too wide for a 6.5J
one ton/Wolf rim as well. The widest tyre I've seen approved for
a 6.5J rim is a 255/85R16 which I have on the 88. I would have
preferred 265/75R16 but the minimum rim width is shown as 7.0J
on the BFG website so I didn't go for it.

So, in the end I got some BFG M/T 235/85 16s, with some ex MOD
6.5 steel rims from VASS. No tubes. All on....lovely. Just took
delivery of some parabolics from GBSprings too. Rang them on
Saturday, left a message, they rang me back at 10am Sunday
morning (!), delivered by Wednesday. Couldn't rate them highly
enough. Better prices than Brookwells or Paddocks and nto
Britpart either. Fantastic.
Thanks for all the tips. Would have cocked up royally without
them. I'll put a photo on soon.
Cheers. Jerry

brill - looking forward to seeing the pics.
I need to replace the 235/85's on mine soon, presently on lwb
rims, and considering getting another set of 6.5 rims from vass
for them.
Don't like wolf rims on a series. gayer than pink frilly
underpants.

Basically; and this debate could go on and on and on, from what
I understand, the easiest thing to do is get some 110 rims that
235/85/16's will go on or if you want more of an offset, wolf
rims ( and probably some longer studs) .
I'm no expert and run gay mods with 650's ( 235/70/16) on. For
better spring plate clearance and slightly upped gearing the
circumfence of the 750's ( 235/85/16) will suit better.
If you use rivetted wheels you'll most likely need tubes unless
you put alot of paint on them, hence using 110 rims.
Thats all I'm going to say, cos! :)
