Tyres Sizes on a Series Land Rover

[92.9]

What is the reason for it not being advisable able to fit 7.50 16 tyres to a Land Rover that originally had 6.00 16? Is it simply a case of messing up the gearing and not necessarily having enough power to cope, or is it also to do with tyre clearance?

If I wanted to fit 7.50 16s on my 88" 2.25 Diesel, what problems might I encounter?

Thanks

The 88 has the same engine/gearbox/ transfercase and differentials as the 109 which had 7.50x16 tyres as standard to cope with the higher 3/4-1 ton payload . 7.50x16 tyres among other sizes were an optional extra on 88''series Landys anyway so go ahead. The only reason 6.00 x16 tyres were fitted standard to 88's was cost and to make the vehicle look like a fat spindly legged old lady with her skirt hitched up.

It's funny because it's true!

The speedo will read a little slow with 750's. There are 2 types of speedometer for 750 or 600.

I've run 750R16's on my 88 with no problems, I just fitted a speedo from a LWB. Personally I think they look better too - not like the 109 that lived in the next street that was fitted with 600 x 16's!

[92.9]

Thanks everyone. 7.50s it is then!

Will those tyres go onto the standard rims, or will I need wider ones?

Thanks

LWB rims are an inch wider (6.5 not 5.5) but I think you can get away with it.

[92.9]

Thanks; I'll look out for some of those then. I also like the look of the wheels that were fitted to 1 ton Land Rovers. I expect they were quite wide to take the 9.00 16s!

[rtbarton]

Use LWB rims, not worth risking it where wheels are concerned.

[bill van snorkle]

Series 1,2,3 swb rims are 5'' wide, Lwb rims for 7.50x16 tyres are 5 1/2'' wide. The 1 Ton and Forward control rims for 9.00x16 tyres are 6 1/2'' wide. Many people over here used to successfully run 7.50x16 tyres on 5'' rims although the tyre companies recommend 5 1/2.

I fit in mine 88in 7.50 tyres in wolf rims. Because the wolf rims are thicker there's a need to change bolts for longer ones.

[tiagoc]

6.00x16 on SWB really look silly. i imagine what that LWB would look like, with them!

if you fit 7.50 on standard rims (without spacers), you'll find that the wheels will rub somewhere (shocks, i believe). you'll need to adjust the stop when turning the wheels.

i use 8-spokes with 7.50 and i would never go back to 6.00. uphills will be slower, but i can live with that

I fitted 235/85/16 on a LWB and had to adjust the lock stops a teensy bit. I'm fitting the same size on catflap (SWB)

You need to add a V8 then

Occasionally I see Land Rovers with standard-looking steel wheels, but there's quite a bit of positive offset, so they look really good. I'm not sure if I'm just looking at standard LWB rims, or if there are wider standard-looking rims available. I'm wondering if I've seen 1 Ton rims.

Paddock Spares list the LWB rims as 5.5" x 16" and the 1 Ton as 6.5" x 16". Will 7.50 16 tyres go on 1 Ton rims? I can't see that the rims would be too wide.

I think these are the wheels I was on about (1 Ton):

[V8Nick]

That's a One Ton allright, but those are the rarer 'extra offset' rims. There are at least two types of 6½" rim which were standard or optional on the One Tons and Forward Controls...

I've got a photo somewhere... Ah, here they are...

Note that the position of the hub, and therefore it's fixing rivets is the only difference between the FC rim (grey) and the Extra Offset rim (silver).

Cheers, Nick

[92.9]

Thanks for posting those photos Nick. Very informative!

I wonder what the rims are that Paddock Spares sell as 1 Ton rims. I presume they won't be the rare wheels that you mention. Maybe they are Forward Control rims.

Blimey, I forgot about this particular thread.  Over a decade since my last post! 

Thanks for the link though, Martin.  Some helpful information there.

I suppose the original poster has got his tyres sorted but maybe he's in for a new set by now ;-)

255/85R16 fits real nice on an SIIA. I recently downsized from 900x16 to this size because of availability, price and weight.

What are those wheels off?

This topic is about tyres. Not wheels, isn't it ? 

These wheels are two piece, forged aluminium, 6.50 x 16. Originally made for one of the heaviest Land Rovers, the Shorland Mk 3 and Mk 5 Armoured Patrol Vehicles.

Being two piece rims it was possible to mount a run-flat system on these. Rim lips are extra wide to better support the side walls

 at zero pressure. Weight including all nuts and bolts is just 13,5 Kg. The run-flat system was optional on the APV's , guess they are pretty rare.

[Daan]

Interesting, you could fit pvc inserts and you have double beadlocks.

 

Groeten, Daan

[AV8R]

Yes, I did think about the beadlocks but I probably will not air down the tyres enough to loose grip on the beads. I might paint some witness marks as they do on aircraft tyres/wheels to keep track of this.

Not worrying about deflations either. Inner tubes are a must with these split rims.
