Tyre size.

[vin16660088]

Hello, i am just wondering what tyre size people are running on thier series 1's, is there a supplier of the original size/type in OZ, if not the 51 (Dingo) is being rebuilt as a daily driver so what would you recommend as a brand and size for daily use on a 80inch, any suggestions would be appreciated, thanks. Anthony.

Hi there Anthony

I am running 700 x 16's on my Series 1 Fire Engine.........they seem to do the job quite fine.

I bought them through my local tyre dealer in Port Augusta (tyre brand MRF) and approx $100 each fitted.

Hi Anthony, I have on my 1951 80", brand new 600 X 16 - 6 ply radial tyres MRF NDMS made in India of the Jeep Ladder pattern(I thinks that is what they are called). I got them from my local Tyrepower Store. He had to get them in but at $120 fitted and balanced (with tubes) - I couldn't say no.

Anthony,

On Shorty I currently have a set of 7.50 x 16's (Bar Tread) but I do have the 6.00 x 16's that came with the car. These smaller ones will probably go back onto her, I have some Deestone bar treads in this size and they were about $130 each fitted with a tube.

When I had my 107" - I had 6.50 x 16's on it.

Anthony,

If it is for a daily driver and you are going to do the distances on bitumen I would go for a 205R16 or 195R16 if you can get them. R is for radial, a radial tyre will be much quiter and will provide you with better performance in the wet than any xply with an agressive pattern like bar treads. I have no experience with the MRF tyres, they look the part for a 4x4 off road vehicle and have a fairly aggressive pattern so will be a bit noisy on the bitumen. I am sure that you will get some who will claim that a LR is so noisy that the tyre noise is inconsequential.

Daily driver, bitumen and rain do not equate to a agressive cross ply but each one to their own.

Anthony,

If you head down the route of fitting a 195 or 205 x16 be careful because the rolling diameter of the tyre (circumference) is reduced which effectively lowers your gearing. The last thing you want on a Series I is to lower the gearing !
7.50 x 16 will fit on the rim but as the rim wasn't designed for this tyre size I'm not sure how you stand on a roadworthy.

Dunlop still make the Road Trak Major (listed now as the RTM) in 7.00 x 16. I fitted 4 new ones for the trip to Cooma and had an old one as a spare. The new ones are made in Indonesia and are now 8-ply (old one was 6-ply), otherwise identical.
From memory about $160 each fitted, balanced and with new tubes. Dunlop bring them in in batches of 100, I remember waiting and waiting and then just getting them in time for Cooma. I've attached a photo.

Do a search on this forum and you'll find several threads relating to tyres and also I remember Diana posted a list of wheel rim part numbers and correct tyre sizes.

Hope this helps,

Colin

600 x 16 = 150 x 100 R16 diameter = 28”
650 x 16 = 165 x 100 R16 diameter = 29”
700 x 16 = 180 x 100 R16 diameter = 30”
750 x 16 = 190 x 100 R16 diameter = 31”

195R16 = 195 x 80 R16 diameter = 28.3”
205R16 = 205 x 80 R16 diameter = 28.9”

Thanks Slug Burner,

I hadn't got figures to hand but remembered when being offered an alternative tyre size to the 7.00 x 16 that the rolling diameter was reduced by close to 9% (by their figures).

From your figures:-

7.00 x 16 rolling diameter = 30 x 3.142 = 94.26"
195R16 rolling diameter = 28.3 x 3.142 = 87.98"

87.98/94.26 = .93 or approx 7% reduction in 'gearing'. The 205R16 is better at approx 3% reduction.

If Anthony is doing long runs then 7.00 x 16's will give the old girl slightly longer legs. For regular wet weather driving or enthusiastic cornering the radials would be a better option.
As you said in your original reply, each to their own....

The original size on the 1951 80" like Anthony has is 6.00 16 in bar tread, or 7.00 16 in road pattern which you could consider equivalent of a 95% on road tyres like Michelin Synchromes etc. You must remember that a '51 is only using the 12HP 1.6 litre engine not the 15HP 2 litre engine like the later ones and pushing around big wheels is a bit much for the poor old dears.

G'day Folks

The rim part numbers are stamped on the outside of the Australian made rims, and the rim size is stamped on the inside in the well of the rim.


R231601 = SWB (88) 5.00 x16 will take 6.00,6.50, 7.00 size tyres

R272309 =LWB (109) 5.50 x16 will take up to 7.50 x16 tyre sizes, this is the standard Aust Army Series 2/2a rim, S3 was AYG 3038 or ROH AGY 8108 also the UK Number was NRC-7578=5.50 x16, from memory.

The R 272309 rim is 1 13/16 inch centre offset,which would give the wides track on a standard vehicle.

205 R 16 is /was the original tyre size fitted to the Range Rover on it's release.when fitted with Rostyle wheel rims.
