My B44 Roadster bitsa is coming together. I plan to use some iteration of the Dunlop K70 on the rear wheel. I would like to use a ribbed pattern on the front, what's available? It will use a later 19 inch wheel with the 8 inch brake.

Why spend all that extra money on a ribbed front tyre (skid master) stick a K82 front and rear and be happy, I’d also stick with an 18” front wheel. Brake size is Up to yoU but 8” TLS is over kill. They used 7” TLS on the triumph Daytona.


Now let’s all have a beer beerchug

68’ A65 Lightning “clubman”
71’ A65 823 Thunderbolt (undergoing restoration)
67’ D10 sportsman (undergoing restoration)
68’ D14 trials (undergoing transformation)

In the UK, you can still get ribbed Avon Speedmaster AM6 19 inch front tyres, I assume they are also still available in the US. Ideally, these should be combined with Avon AM7 Safetymileage rear.

If you're not too worried about classic looks, go for Avon Roadriders which will fit classic bike wheels sizes and offer excellent handling.

The Avon 3.25x19 Speedmaster Rib front tire is readily available. Here are just two sources but many, many vendors carry them.

This is a bike that will not be ridden a great deal. It is kind of a styling exercise. I am concerned about a 'classic' look before performance. I'm using an 8 inch SLS brake.

Good, then either the Avon rib or the K70 3.25x19 will be ideal for you.

Heidenau k44 on the front. I race on the K44R on a A65. 3.25-19
Ribbed and modern.
More tire than you will ever need.

https://www.heidenautires.com/product/k-44/

Match it with a k34 on the back.

https://www.heidenautires.com/product/k-34/

Bigger is not always better. 3.50-18 (?) on back.

I race the K34r 3.50-19 also on the a65 rear and I have K34s front and rear on a street 1964 Lightning rocket. On the street bikes I run 24 psi front and 26 psi rear. High pressures cause the Front K34’s to wander on rain grooves. Lower pressures cure this.

My 1963 A65 Star has 3.25-18 and 3.50-18 K34s on it. Pleasure to ride.

These tires have a round cross profile when compared to a K70. So the handling of the Heidenau is quite neutral on roll in or rollouts. The lightning rocket and the race bike are quite flickable if you know what I mean.

YRMV.
