Early Fastback front tire

What are you guys who have an early Fastback using for a front tire these days? Since the narrow Dunlop is no longer available, and a K70 is too tall, what's left? A pal is looking for a tire that will work with the narrow fender.
Thanks!

I got an Avon Speedmaster 300-19 from Walridge maybe 5 years ago.

I'm using a 90/90/19" Avon Roadrider. It fits under the narrow front mudguard fine. The original tyres are still available. The front is/was a 3.00x19" Speedmaster. The rear is/was a 3.50x19" Grand Prix which are made in small batches, & whilst they are quite expensive they can be purchased from Vintage Tyres in the UK.

a 3.60 K81 TT100 will go under that front fender , will it not . ( actually 3.25 / 3.60 )

good to have matched F&R tyres . Early triples with drum brake and the old K70 front with a TT100 rear
wernt the best steerers under duress . Might be discribed in somewhat harsher terms . Not worth your life .

The nowadays K70s are better than the old rubber , and a good multi purpose ( sealed / unsealed / dirt - tyre )
The machine should DRFIFT comfortably. Not have pronounced understeer or oversteer ( front or rear WASHING OUT ) .

so dont mix radically differant tyres .

I would go with the 90/90 Avon Roadrider. It is a much better tire for the road. If you want to trailer it to events then choose the replica antiquated tire to get the points.

Agree with CNN. It depends what you want to do... For riding Avon road rider seems to have the best reviews I've found. Have ordered Avon road rider 90/90-19 for the front and 100/90-19 rear for my 68. Rear rim is replaced with a WM3. Haven't got it yet so can't give personal opinion.

+ 1 on Avon Roadriders, I think they are awesome tyres.

You may find Avons web site useful and informative, it gives a lot of dimensional information for their different tyre offerings.

It also shows, contrary to popular belief, Avon tend to specify wider rims than were generally fitted by Brit factories in the day, and even still fitted by wheel building specialists today (I had to insist most strongly to make Central Wheels fit the correct rims for my tyre choice, even though they also provided the tyres!).

The nice thing about Avons is that they stick right away, no break in necessary. I bought some Metzlers for the Daytona and went down coming out of the first corner on very gentle throttle application. I didn't mount the tire (190, too big) and hadn't noticed the coating of slimey form release all over it.
Avon must have an extra process which removes the slime. New Avons squeak like grippy running shoes on bare concrete, Metzlers do not. Wish I had noticed the difference before riding!

My Commando has 100/90/19s Roadriders on Flanged Morad WM3 s (Central Wheel) front and rear . The handling is wonderful.
As Nigel points out, wide rims are needed for small tires with the Roadriders. The WM3 is the minimum recommended width for the 100/90/19, WM4 is ideal according to the Avon chart. Central Wheel did not have WM4 in 19" at that time and did not know when they could supply them, so i went with WM3.
The WM3/ 100/90/19 Roadrider setup works down to lean angles where things are scraping, good enough!
