I found this new (or new to me) tyre on Aliexpress and it actually seems pretty good compared to other cheap tyres I've tried. Not sure if anyone else has tried these Arisun R1. Check the table for the specifications but at £25 they are very competitive with other options out there.
My current favourite tyre is the Schwalbe One and it seems like a potentially great alternative. Unfortunately the R1 doesn't meet it's claimed 35mm width but it's still wider than the Eagle F1 which are the ultralight king but a bit too narrow for my liking.
Anyways, hard to draw conclusions before putting some serious mileage on the tyres. But it definitely slots nicely between the Schwalbe One and Eagle F1.
Originally i was going to just measure the actual width of the tyres on the wheel but then I went kind of crazy with it haha. You can see my testing/measuring methodology in the youtube video I made: https://www.youtube.com/watch?v=Vj02TrbWBvg
Also, it looks like Arisun have a nobbly tyre, if it's a light and supple tyre it would be a welcome alternative to the pricey Schwalbe Almotions. I haven't seen them for sale yet though.
