Hello all. I have a 1971( frame)/1972 engine T120 R. I need a new rear tyre. Front tyre 3.5 x 19 is a new Dunlop K70. I know it's supposed to be a 3.25 x 19 but here in Thailand 3.25 "No have, no have ". As a rear tyre, recommended size is 4.00 x 18 but in Thailand I can only get K70's in 19 inch sizes. "No good, no good."
I can get a 4.00 x 18 K87 however . I do not know this tyre from experience.I'd like a narrow-ish rear tyre ,unlike the rather massive Conti it has now ( and which makes it steer like rubbish). In your opinion does a K70 front and a K87 rear make a good combination ? Thanks in advance.

I got just 2000 miles out of the last K81 (Don't know what a K87 is) I tried. That's just not good enough now matter how cool they look or how well they stick to the road. I replaced it with a more modern tire that will go at least 10k miles. Bill

I currently running K70 tires on my TR6 because I wanted the original look. I would not use them again. I would say if it's not a show bike, put modern tires on it. Avon Roadriders come in English sizes.
Avon? Sounds expensive...When refurbishing my 72, I acquired a couple of "Chen Shing" tires, don't remember how much I paid for them, but they have worn really well after about 3000 miles(Front still very meaty), and as far as I could tell, handled just fine. Im being told these tires are very cheap and low quality, and that my bike would ride alot different with a quality "Avon" or something on it. But honestly, I have had no problems with them, and I've put ALOT of mountain road miles on them. Will probably replace the old trusty "Cheng Shens" (or whatever they are) over the winter time, and have new tires for the 3 state ride in May.
If you love it, let it go. If it comes back, you've highsided!"
