Those Avons are used by many Morgan Competitors, because they give exceptional grip in both wet and dry conditions.
Dave and I have discussed this on another thread, it may be the conditions he found were exceptionally testing for a tyre with minimal tread, pattern and therefore limited ability to clear deep water BUT under all other conditions they are superb. In the dry they will hang on for ever, you will run out of brakes before you run out of grip. On a "normal" wet road they are also excellent and you won't need to slow down too much from your dry speeds (but please remember you have no abs in a Trad Mog and therefore should use cadence braking)
You do need to scrub them in well before using them in anger (like a track day) but once ready they will give great performance . Don't worry about warming them up, they are a very soft compound and will start to respond well from the outset.
Apart from deep water clearance the only real downside is the price.

I have to agree with Andy, There is one thing to add there are Two compound choice's Hard and Soft. The soft not an option for Road use and should be avoided. Kind regards Cain

Thinking of upgrading my 4/4 to a narrow body 4/4 and asked the factory the tyre size which nobody seemed to know! Have heard that some have the speed tyre CR6Zzs but to use these on the road would probably damage them due to lack of heat required to race this tyre. Did borrow a +4 gdi from BHM for the morning which was a great drive with 16 inch Avons but lacked the feel of the 4/4 at lower speeds in my opinion although the extra power was great together with steering hardening up when cornering at greater speed! So now need to drive the narrow version! Anybody owning one woul appreciate advice on handling, suspension etc.
RogT 4/4 Ort Sand HDY Roger , Thinking about this again , the factory fit 2 different Avon tyres to current cars, firstly is the CR6 ZZ that we have been discussing above , but they also fit the ZV5 , which is a much more "general purpose" tyre. I have those fitted to my +8 , and in general I am pretty happy with them. It cost me about £220 for a set , fitted, and I would expect to have to replace them after 5 years well before I wear them out. The CR6 ZZ are approx £200 per tyre, and (provided you go for the hard compound) will probably be much closer to the wear limit at 5 years. You might want to check with BHM which Avons were fitted.

I needed to take advantage of this afternoon's fine weather , so I took my +8 out for a drive down to Borough Green and visited BHM.
I can confirm that the BHM `+4 demonstrator (the lime green one) is shod with Avon ZV5 tyres and not the "competition" CR6 ZZ. They are 195/60 x 15, but there may be other options.
Just out of interest I asked Keith (who has driven more different Morgans than most) about the CR6 ZZ which he has fitted on his own 4/4. He is of the opinion that they cope with deep water very well indeed, much better than any other he has used on Morgans despite the lack of any deep tread. He does also agree that the levels of dry and wet grip from these tyres is exceptional , the only improvement he could think of would be pure racing tyres.
