Wheel rim original size & what make tyres to fit ?

(1/4) > >>

McCabe-Thiele (Ted):
I've just checked my old wheels they are fitted with the following that look original as regards rims etc the tyres have never been used on the road.

Front Rim is marked DID 1.60 x 18 Tyre fitted is a 3.00 x 18 Pirelli Tyre MT65  marked for US only (made in Brazil) they have rotational arrow marking.

Rear Rim is marked DID 1.85 x 18 Tyre fitted is a 3.50 x 18 Pirelli Tyre MT65  marked for US only (made in Brazil) they have rotational arrow marking.

As they are for the US market I can't see any obvious year of manufacture. I will probably just keep these as spare wheels as they are.

I am fitting new alloy rimmed spoked wheels of the same size just need to take advice on tyre brands of choice these days - last tyres I bought were Metzlers on my XJ900.

What tyre makes are folk using here on the 400/4 & aspect ratio to keep as standard ?

Your tyre was manufactured the 39th week of 1995

 With the greatest respect Ted, the best thing for tyres which are 26 years old is a hacksaw cut right through them. I still have clear memories of a close friend of mine buying a used Suzuki Super Six which had been stood unused for just under two years. I watched as the rear tyre let go on him on a dry tarmac road. It will also enable you to see the condition of the rims on the inside. I always thought that my rims were in good condition, especially the rear one because it was kept rust free dut to chain lube fling. When I went to change the tyres, the insides of the rims were dangerously corroded. New standard size D.I.D. rims and spokes from Silvers, and to keep a fairly traditional look, I had Dunlop K82 tyres fitted. 3.00 x 18 front, and 3.50 x 18 rear. Classic tread pattern but modern rubber, and give enough grip for my antics, but at 74 years of age I think I'm probably more fragile than the bike now. Take care and have fun. Mike.

Thanks Mike,

For the tyre age information they are too old to use I did not know the tyre age code - I agree completely at 73 yrs of age I too feel vulnerable on anything but the best rubber.

I have been a little ambiguos in my post I have no intention of using my old wheels & tyres I am getting a new set of wheels made up by central-wheels.

I'm after advice as to the best all round tyre brand and the correct size fitted as standard, the tyres do not appear to have an obvious aspect ratio unless I'm missing something.

The aspect ratio I think, in broad terms, is because they are likely the same height as designated rim width and make them 100% with no protocol to mark them as default.
