Not sure about it. The biggest I've fitted so far was a 130. A 140 may *JUST* squeeze in (assuming that you still use the chain enclosure) without rubbing on the chain boots.

ok,,thanx for input.
seams to must ride with original tyre then.

Schorrsch fragt das weil er immer noch den ersten BT 45 drauf hat seit 81....... ......ne im ernst, der BT45 ist auch meiner Meinung nach die beste Wahl für die Trine. Langlebig mit gutem Gip und der Preis ist auch in Ordnung.

Regarding the "a 140 tyre came off the rim" part, you have to be aware, that your rear rim is only 2.15" wide and that the recommended minimum width for a 140 and beyond is a 2.5" rim, so even if it is fittable, you will actually run it down a lot faster, because of its balloon-like shape AND it may induce some rather bizarre handling qualities… (mostly I'd say a trade off in straight-line-stability vs. slightly increased cornering feel).

Hope this helps
Cheers,
Greg

P.S.: If the 140 came off the rim, it was most likely low on pressure or damaged during installation. At least that's my guess.

It's cast onto the wheel ..... Perhaps it needs a wash????
