Does anyone have an Avon Safety Milage MKII - 4.00 x 18" tyre fitted to either of the following rims?

If so could you please measure the actual width of the tyre at recommended pressures?

1. WM2 (1.85") x 18"
2. WM3 (2.15") x 18"

The Avon website gives the width at 4.40"
So why is the tyre not called a 4.40 x 18"
 
Hi Possum,

Whilst I don't have anything with that tyre fitted, I have always found the Avon site to be accurate & far more use than any other tyre manufacturers site, most of which are close to useless.
The size ratings of tyres is crazy. If you take the example of a 120/90/18 some makes are 114mm wide whilst others are 116, 120 & 124mm all on the same WM3 rim.

The 4.00 x 18" tyre is a throwback to the pre metric tyres – Avon amongst others produced this tyre because there was very little else on the market at that time. Wheel rims widths were designed for different purposes, i.e. Load of bike, tyres the same, including max top/permitted speed e.t.c.

Don’t believe the (tyre width) hype;

Often tyre widths are fractionally different to even the manufacturers published dimensions. Usually it’s under-sizing by one or two millimetres. The position of shoulder tread blocks, rim width and tyre pressure the manufacturer uses for their control data is the root cause. Nothing unplugs the truth like taking a set of Vernier callipers and a digital pressure gauge into a bike shop and finding out for yourself.

A friend has a new one on his Commando, and it seems to be working fine for him. It is a pretty soft rubber compound, and the bike handles just fine if you just want to ride and not scrape the footpegs.
 
I have a 400-18 on the back of my Series II Interceptor and I rode it 88 miles yesterday and 60 the day before so it gets used.
They are very square in profile. The contact patch is almost the full width of the tread. Modern tyres only get a big
contact patch when they are nearly worn out. When leaned way over I can only imagine what the contact patch looks
like and indeed, what the tyre looks like. The rubber feels fairly soft though it wears well.
It is not the tyre profile you would select for your serpentine road footrest scratcher. On bad road surface it tends to move
around a bit. On good surface I have no issues.
Oh, and as mentioned before, the side walls could repel a battering ram and I find it impossible to mount them with spoons.
