Can folk who run or have run these advise as to their compatibility with series vehicles.

I know that have a thicker centre.  I wondered about clearances, offsets and if series wheel nuts have the correct bevel to attach them.

My focus then turns to tyres.

I run LWB rims with 7.50s and an overdrive at present.

I was thinking of 205 16 tyres, but feel I would miss the taller gearing of the 7.50's

Am I correct in thinking that 205 are very near identical to 6.00x16 in height and circumference?

I also have MAP FWH and wondered if there is any conflict with the discovery rims.

I have zeus disc brakes on my Dormobile. The options were wolf or disco 1 wheels
I haven't got fwh, never saw the point of them, but everything else works with the wolf rims, so can't see why disco 1 wouldn't be the same
6.00 x 16 are very similar to 205s in circumference, but all makes vary a considerable amount. Obviously they are much wider
You would need to get the appropriate speedo to match

[2286]

Vehicle was originally on 6.00x16 it was the first thing I changed.

I retained the speedometer.

The width could be an issue as I am researching assistor ram for current set up.

I also have some 7.50 crossply that I may try versus the 7.50 radials as I have been led to believe they give a lighter steering feel?

Like Akrc I have Zeus discs fitted, when I first had  them I borrowed some Disco steels to check as I thought I was having clearance issues, they fitted fine and no issues with my MAP FWHs either.

[2286]

I am on 10" drums with the later larger wheel studs.

Are the series wheel nuts the same and correct for the discovery rims.

No issues with tyres fouling the springs, chassis or bodywork particularly the front when on full lock.

With them being land rover is it insurance company notifiable if they were to be fitted?

I think 205s are closer in circumference to 6.50s than 6.00 ?

Happy to be corrected.

I wonder how many Disco 1 finished their lives on steel wheels, the craze was to swap them for alloys at the earliest opportunity !

I'm running 235 65 16 on Disco 1 rims with no issues. No noticeable in turning circle either. I also have parabolic springs.

Mine still has them. Look the part more than alloys.

I've had D1 steel wheels on my 1967 88" for years with no issues,
I had 10" drums all round but now have 11" on the front and 10" on the back
The studs are still the thiner early type but I use the nuts that are 27mm on the outside but fit on the thiner studs, part number? but I'm sure its on here
When started I used 205/16 tyres but now run 235/85's
A lot of people dont like them but I painted mine satin black to dull them down a bit.
I only paid £5 each for mine and now have a number of spares, so a lot cheaper than Wolf's

[2286]

Thanks all.

I did some number crunching and genem is correct that 205's are closer to 6.50.  With that in mind did land rover have a speedo head for 6.50's and what is its part number in series 2 and series 3 guise.

I personally like steel wheels over and above alloys.  Of the steels I like disco hence acquiring them way back.  The only exception being 8 spoke wellers.  I saw on a large land rover part site that new disco 1 rims are approaching £300 ea!

On the same site avon 6.00 were nearly £350 a piece.

So it seems to canvas opinion really does save time money and effort.

I had found some 205's on disco alloys locally for very little money, but the cost to swap them to my disco steels is more than the cost of the tyres.  When all that is done it seems the 205 has fallen out of favour?

Oh to be young and have the use of a tyre removing machine!

Hi,

The TPM (Turns per Mile) should be embossed on the tyre's sidewall, but note that the TPM can vary  between manufactures.

Some forty years ago, an enthusiast's magazine (KIT CAR? HOT CAR?) published a table of tyre manufactures  listing tyre sizes & TPM. There were some big differences. I don't know if anybody else has published anything similar.

Some 50 years ago our convoys of Leyland Hippo 6X4, carrying "unclean warheads", accompanied by "Snowfrops" carrying loaded .38s. The Hippos had (from memory) 20" x 10" tyres ... a wheel and tyre weighed about 2cwt. All tyres were remoulds, all produced by the same manufacturer.

I "had cause" to measure the circumference of two tyres on the same vehicle. There was 10" difference.

602

[2286]

I have had a look at my circa 1982 series 3 brochure and the 88 county was fitted with 5.5f rims (lwb) shod with 205x16 radials from new.

Then I looked at the s3 parts book and only two speedometer heads were offered, one for the smaller 6.00x16 and one for the 7.50 x16 fitted to 88 as an option or 109 as standard.

Would I be correct in thinking that the 205x16 fitted to 5.5 rims would reduce the sidewall height or aspect if compared to the same tyre fitted to the 7 inch discovery steel rim?

Thus the 6.00x16 speedometer head would be closer to correct.

Failing that was the 88 county fitted with a unique speedometer head that is not listed anywhere.

Speedometer input drive ratios I assume are fixed in series boxes where they have interchangeable colour coded pinions on the LT 5 speed.

Out of curiosity I searched leyland hippo, and they are earlier in manufacture and different in appearance to what I had in mind 602.  Like a baby aec matador.

Tire calculator Android App is pretty good

[2286]

I have no tech other than occasional internet.  Is there an equivalent site to the app you have in mind?

Other than that I have been doing pie r squared on width and aspect plus rim.

[Rustandoil]

There might well be a online version of the App, I will investigate
