They fit on mine but I've got wheel spacers so I don't loose the turning circle and a +3" lift, although there are plenty around with the +2" lift that have the 33" tyres fitted.  :wink:

You may find that the overall gearing is effected by the increased dia of the new tyres, in my case I changed the transfer box for one out of a Defender (1.41:1 ratio) to bring the gearing back to about normal. When I first fitted the tyres the Disco felt very sluggish, I couldn't get into 4th unless it was doing over 35mph otherwise the engine was labouring too much. Also, even on the motorway, when loaded, I found I had to go into 4th on some hills and heading up the M6 one time I was into a head wind and going up a long, but not really steep, hill I had to go into 3rd!!  :shock:
The speedo was also way-out but with the new transfer box it only reads 2mph slow.  :D

IIRC the speedo reads under as the large dia tyres mean less rev's of the wheel.
I have Scorpion Pro-Spacers fitted. Had them on the Disco for about 4 years and provided you keep a check on the wheelbearings so they are greased and tight then I've had not problems.
Get a set that are TUV approved and have the centering lugs on them. This way you know they have been tested, will aline the wheel and are fit for purpose.  :wink:

If the tyres don't already have wheels fitted then you go for wheels with a different offset, which means you don't have to get the spacers!!  :wink:

Budgie, they are on 8 spokes so i guess no spacers needed? !

Maybe they are on wheels, but, what width are the rims, and what offsert are they..... it all makes a huge difference!!

I think mine are on 8Jx15 8-spokes (that's what they were supplied on before anyone asks  :wink: ) and still needed spacers.

10Jx15 you may get away with, but you may still loose some turning circle.

I run 10x15s on my 90 with no steering stops and they dont rub. Still got good turning circle. Just about to put them on a disco (300) but it already has 90 transfer box so should cope fine. will let you know ! :shock:
