H: Hubs, Wheels and Tyres 4.00-19 rear tyre advice please

[Peter Holmes]

It would interesting to know whether the tyre to mudguard clearance issue became more evident when we swapped our original Birmabright mudguards in favour of stainless steel mudguards, it is well documented that they were not always that accurate in manufacture, and required spacers fitting at the front fixing point, and pulling around a bit to get the radius sort of correct, bring back Birmabright I say!

Her a picture .The profile is period looking and the grip on tarmac is modern.Erik

The radius of mudguards can be altered by springing them wider or narrower this alters the curvature they are not really a braced solid object

I have the Heidenau 4.00-19 on my Comet without any problems with the space. Erik

which type of Heidenau?

There is no special name on the Heidenau. Only M/C 4.00-19 ! that is all I could find. The profile is a little bit like the old Metzeler Block C . Erik

Hi Kerry,
I use the Avon Roadrider 2 on the rear of the Shadow and on the Rapide.
Apex style tyre much better road holding.
I recommend using the 100/80-19 rather than the 100/90-19
Reason being better match for the roadrider 2 front and gives better clearance for the rear guard.

I use 90/90 19" front and 100/90 19" rear Roadriders on my Rapide and it seems to handle pretty well to me. There's loads of space between tyres and mudguards front and rear. Since 102mm is 4", I assume that equates roughly to a 4.00?
