I need to order and fit new tyres to our 1948 FS as the ancient rear is crumbling away after all the excitement of being used in anger this year. Currently I have the following fitted;
Front: 3.25-19 Avon Speedmaster MK11
Rear: 3.25-19 Dunlop GoldSeal K70
I do not know if the rims are standard sized or not which obviously doesn’t help. I would appreciate any advice as what tyres I could fit as I have effectively no idea what people fit to “old” bikes. I would prefer good handling and grip to a “period” appearance. I would certainly rather avoid a Speedmaster rear as I hated the feel of that on my dads Speedtwin (why on earth did someone think it was a good idea to design a rectangular section tyre??).

Go for Avon Safety mileage SM 3.50″ x 19″ or the same size Dunlop Universal.
I should have said that those are for the rear. 3.25 x 19 for the front.
If you’re looking for a more modern tyre I can recommend Avon Roadriders which I have on more than one of my machines. Check them out here: https://www.avontyres.com/en-gb/tyres/roadrider?cartype=motorcycle
Thanks to you both. The rear rim is definitely wider then the front (~3.0″ vs 2.5″ outside width) so I’m a bit baffled why it has a 3.25 section tyres on both front and rear. Clearance doesn’t look like an issue so I don’t know why the correct size rear was not fitted. My current preference is for more modern section tyres so I’ll have a look at the Road Riders. The budget option appears to be Mitas tyres – can anyone comment if they are any good?
I went with the Mitas tyres in the end as I could get a pair for £88. A single Roadrider was about the same price so it was a big saving. They have a fairly “modern” profile and I suspect they will be fine with the limited performance of my FS. They also went on without a struggle which was a bonus.
