Thread: Cooper ST's on a Disco 2

Aha....and now I am confused again! So if my 1999 Disco 2 handbook says the same thing (dont have it to hand, but think its similar), is it ok for me to go and put 225/75/R16 tyres on it or not?!

I went to my local Cooper dealer at lunchtime and he definitely will not put 245/75/R16s on. He says they rub without a doubt. I kind of believe him as what does he has to lose? He is actually persuading me into getting the cheaper STs at 225/75/R16.....

They were great on my forester!

You can fit them, but they might be a little smaller.

The 245/75 R 16 won't cause any dramas. As mentioned, a friend of mine has that size on his Disco II, although on 8 inch wide rims.

My 265/70/16 didn't rub but they looked HUGE in the arches. Now they look small with a 2" lift.

Any chance he has a set that he's finding hard to sell?

Apoligies if this was not you Baz.

Yep, I would read this thread carefully. The original Cooper ST is still the same as when it came out. There was the ST-C which is the same tread pattern but with a softer compound which they thought would prevent the outer lugs from being torn off the tyre - and this in it's limited size range has been met with mixed success.

I would not ever fit the Cooper ST to a Disco2. I don't believe the manufacture of the tyre is satisfactory, and I believe the fragile design of the tyre which is intolerant of wheel spin (which causes outer lugs to tear off) is incompatible with ETC traction systems.

These are 265/70/16's on a D2 which has not been lifted.

They do fill the arches a fair bit more than the original Michelin's, but there is no problem with rubbing on anything. They have made a huge improvement in the way the vehicle rides / travels. The only problems are that the speedo is definitely a bit out, though I haven't had a chance yet to measure against GPS (I'm guessing about 10% error based on indicated speed vs rpm compared to previous), and that the spare would not fit onto the carrier in it's orginal position - had to raise it by about an inch, which is a very easy mod.

Changing tyre size won't have any effect on the indicated speed vs RPM equation. The change is downstream of both the RPM sensing (tacho) and speed sensing (speedo) so the relationship between the two won't be altered.
