[net.cycle] Tires & Speed Freaques & Swingarms...

Well folkes, last night I just destroyed a Pirelli Phantom+1 rear tire
that still had good life left in it.
(sigh, i didnt need that $145 anyway...:-( )
 
On my rz350, I had a 120/90 tire
I got a new chain, and the tire came within 1/4 inch of the swingarm
(plenty of spare room!! :-) :-)
 
Wellllllll....., I took our local super highway (speed 60mph) and
travelled about 70 miles to a concert I was late for (at about 80mph constant)
 
Guess what!!! Tires (especially those that are inflated for full load)
can expand upto a HALF inch.....
Poof! 1/4 inch disappeared off the centre of my tire.
So be warned when using slightly oversize tires at high speeds with
minimum swingarm clearance!
Oh yes, I didnt notice the blue smoke coming off the rear, RZs always have
blue smoke!

ps: no accidents or anything, in fact i made the return trip in total
   ignorance, but close to the speed limit since i wasnt late and low
   on gas. I noticed the damage today when i got onto the bike with
   cold tires, felt like a rubber rear axle when i cornered.
pps: 110s look kinda cute on my bike :-}
