Tyre question
« on: 17.09. 2017 17:57 »
I will be needing new tyres/tires soon. I bought the traditional Avon Speedmaster and Safety mileage when I put the bike back on the road. I think the Avon's look proper; I don't like to see modern tyres on a 1950's bike, especially when you can see a large gap between the tyre and the mudguard/fender; however I don't think that squareish profile on the rear is conducive to good cornering. Can you recommend a tyre that looks good on an old bike yet gives good handling?

Mitas H02 at the rear, and H01 upfront. Keep 'em pumped up to 32-35 PSI
At the rear you can go up to a 4.00 width, wich I find way better looking than the usual 3.50, but that's up to anybody's taste...

I always preferred Dunlop profile ( more rounded )
360 x 19 Dunlop Tyre TT100 K81 available here and elsewhere https://www.feked.com/wheels/tyres-and-tubes/

1961 Flash - stock, reliable, steady, fantastic for shopping
1959 Rocket Gold Flash - blinged and tarted up  would have seizure if taken to  Tesco

Avon Road Rider for me - yes I know, modern profile. Used to have spedmaster/SM on, but the Road Riders has transformed the bike in my opinion, I feel much more confident with them, used to have an unsure feeling with the speedmaster/SM when getting low in the corners or roundabouts, not with the Road Riders. So for me the looks come second to the safe feeling

Thanks for that Joergen. I also feel unsure about leaning the bike over too much with Avon Safety Mileage on the back hence my question, however I'm not willing to put low profile modern tyres on a machine that's as close to original as I could get it so I'd like to hear other opinions on tyres that look ok and feel safe. I think my main objection to moderrn tyres is the large gapping between tyre and guard. Does the Dunlop K70 (https://goo.gl/W68Sgk) look ok? Anyone got a photo I can see?

A10 with Road Riders front and rear.

The rear is not much different in size to the dreadful Avon SM. The Road Rider front is a bit bigger than ribbed Avon Speedmaster.

Tyres for safe riding in my opinion.

Those tyres look ok.

By the way: If you are about to put that dog in the rubbish can I have him?

I'm impressed with the grip of those tyres!

Seriously though those tyres look just the job. What size are they? Looks like you have the same tyre front and back.

I thought I looked after my bikes and the A10 had an MOT in July (1961 so has to have one), just checking sizes for GB and the rear is bald !!!!!

Both Dunlop goldseal K70
Front 325-19
Back 350-19

Think I will order the same again, also need tyres for the A7 (showing some small cracks) and the Notrun, (so old there is no date on them but they are nice and soft and no cracks) which is running and clocking some miles.

I run a 4.10 (equivalent) avon roadrider on the rear of the A7, I have since I had it at 17 and see no reason to change now.

What's the significance of the 'Goldseal' name?

Heres a pic of  Dunlop Roadmaster TT100 K81  4.10 x 19 on my GF

No problem with fitment on the rear but just to big for the deep valanced front fender clearance.

I fitted a different front mudguard (mocked up in pic) and achieved better clearance but still a bit tight for this sailor

I'm guessing K70 would fit me better

They were fitted to my B series and I found them to be a great tire
