Standard steelies for 110 Defenders (and Counties, and Series 3, but before that I dunno): 5.5 inch
Steelies for Range Rover Classic: 6 inch
Steelies for 130s: 6.5 inch
Steelies for Discos: 7 inch
Alloys for RRC/Disco/Defender: 7 inch
You can find other widths after market and I gather early SWB rims are 5 inch.
Depending on tyre and fitter you can put some 235/85/16s on 5.5 inch rims (I have some on mine). There are different wheels, of course, but a certain amount comes down to construction and offset when it comes to codes. For example the Series III LWB rims and the County rims differ in construction details but are otherwise identical for dimensions. Different codes of course.

and dont forget the Aus. LR milatary rims that look exactly like a series/110/def steelie but are 6.0 wide

Happy to edit but my understanding is that the military rims are still 5.5 inch but are uprated for strength and that Series 3 military rims are greater offset than Series 2/2a. There are visual differences: the Military Series 3 rims have a ridge raised between the wheel nuts which the later wheels lack. But the dimensions (width, offset) are the same.

Reference:
Australian Military Tyre types -REMLR

The 5 I have, and a mate also has 5, are 6 inch wide. These have the rasied rib between the wheel nuts. I will dig out numbers of them. they were bought from a memeber on this site. When I posted a wanted add, I got more than one offer. So they are out there.

235/85R16 33
I got a set of defender [UK] wheels last week from the wreckers..rims are 5.5jX16 33 cooper discovery S/T 235/85R16 33 looks ok.

spare was 7.50 16 8 ply desert dueler.it looks under sized on my spare.

disco steel is 6 inch,205/ 16
alloy 7 inch.16-31

disco 93 auto V8. stripping a 89 hiline.
im using on my disco A range rover 3 spoke 7X16 31,the original tyres are 245/70 16 bridgstone A/T.spare is 6j X16 avon rangemaster[as new].these ride a steer great.

the new wheels just fit the disco and are noisey-hard to steer when cold and has dropped power between 60-90 kmh.

the 6JX16 perentie wheels I fitted up was 7.50 olympics and these didnt look under sized at work we use a hankook 7.50 12ply and these look fine.

have lots of 5 inch wheels around farms and old bush fire trailers.
ROH wheels and ive seen these on SWB.

The master of all things Military Rover, UncleHo, says there are some late Series 3 6 inch rims. I accept my error.

I tried to edit the original listing but the system won't let me back there.

On the original question ...

What about basic commercial 7.50/16s?

Or these?

Have you tried to get some Road Grippers from a Land Cruiser, most Gov. dept and many companies fit after market wheels and 265/75R16 tyres from new.

Tony

So is there a difference between a 7.50x16, a 7.50-16 and a 7.50R16? Some of the road grippers I have seen are 7.00 - 16 rather than 7.50 so will they have the same tyre height? My main concern is making sure the overall diameter is the same so the speedo is accurate. You seem to be able to get plenty of cheap 6.00 x 16 bar tread tyres etc but I'm unclear if the number 6, 7 or 7.50 refers to the tyre or rim width, how do you know you are getting the right profile unless you measure every tyre?

My understanding (and happy to be corrected;)) the older sizes are 100% profile (aspect ratio). So 7.50 has a tread 7.50" and sidewall 7.50". So the diameter is 16+7.5+7.5 = 31"

Therefore the 7.00 and smaller would have correspondingly smaller diameter.

I dont think the format matters - although "R" indicates radial.

Tyres do vary a bit and if critical take a tape measure.

ish

I think the nominal total diameter of the 7.50/16 (however spelled and radial or bias ply) is 32 inches. But the smaller numbers are smaller in every direction. Most people wouldn't notice the smaller diameter of a 7.00 bar tread BUT you really don't want a bar tread for their look on a car used as a daily driver. Bar treads are for heavy-duty mud work - tractor work.

Series Land Rover speedos are not accurate except by extreme good fortune. Just learn the error and adjust your driving accordingly. After 5 speedos in 4 cars, I have had only one exactly correct.

The 7.50 tyres, or the 235/85, are the ones you want, in a tread which is functional on-road even if you want an off-road look (and/or function). Unless you plan to do mostly off-road and rarely highway driving, go for a radial construction.
