From: stephen.packer on 8 Aug 2010 03:21 Air in modern tyres is surely optional. I was flying on Tuesday and left home with 1:20 before the flight (100 miles normally fine in 1:15). On Monday evening I'd changed the rear wheel on the K for one with an Avon Roadrider on; it was a new tyre I'd fitted six months ago and done about 10 miles on. As I left home it felt 'odd'. Ignored it. Got to heathrow fine but at around 100 it was on the verge of going into a weave. I put it down to some pirelli front, avon rear thing. Left for home on Friday and it felt odd. Even worse it was making funny noises. I blamed the wheel bearings. Got home and inspect. It's hot and sticky to the touch, nicely scrubbed in to within a few mm of the edge of the tyre. Something's not right since I've done a 200mile motorway trip. Check the tyre pressure in the morning... 6PSI. Ah. that'll do it. Added some more air and it's fine. Must keep an eye on that.

My K rear tyre definitely loses significant pressure over time (like a couple of psi a week). I've been wondering whether it's an ill-fitting bead, a porous rim, a slightly iffy valve or a combinaton of any/all. -- BMW K1100LT Ducati 750SS Honda CB400F Triumph Street Triple Suzuki TS250ER GN250 Damn, back to six bikes!

Looked fine from the outside[2] but totally bust up the sidewall inside. YMMV [1]Once on the Triple about three years back, total about 20 miles, once in the GT about a month ago. Total unknown cos the sidewalls are so stiff anyway. [2]So much so that they kid at F1 was very determined that I wouldn't need a new tyre, just a repair. Until he took it off, that is. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) 116 Giulietta 3.0l Sprint 1.7 GTV TS GT 3.2 V6 Triumph Sprint ST 1050: It's blue, see. www.cuore-sportivo.co.uk
