Thread: Tire Wear

What pressures are you running and what kind of tire?

i had 36 in them if memory serves me correct. they are the stock diablo corsas.

You might want to increase pressure a little bit. I can't talk to the Diablos, but the front Dunlops on my VFR would cup if I ran them at 36psi ... and no cupping at 38psi.

Also, check to make sure your head stock bearings are tightened correctly, and your front wheel bearings are good. You can sometimes see the tire wear from these before you feel them in the bars.

if i got parts wearing out that quickly i am going to be upset. they are not cupping bad, but enough that i can see it

I didn't catch how old the bike was, so I mentioned those parts. On my VFR, that 2 psi difference was enought to take tires that would show signs of cupping within 500 miles, to no cupping in 5000 miles. This trend continued over several sets of tires.

i will try to bump up the pressures a bit. i think i have about got my moneys worth out of them, i am just above 9800 miles on them. i was running the stock psi and i wound up dropping the rear due to it feeling a bit loose on me.

so its safe to say they are just gettin worn out

Some would likely say they were worn out 4k miles ago. But that depends on how abrasive the roads are. It is time. Best I had was about 12K from a front, but those tires weren't as sticky as the Diablos.

Corsas need to run higher pressures. I was running 33/36 on the track on the advice of some more knowledgeable folk. I'd imagine you'd want something a bit higher for the street, maybe 36/38.

edit: i missed that 9800 mile part. What The French, Toast? I haven't gotten more than 3400 miles out of a set yet.

now that we have established that i have worn out tires and low air pressure, should i go back with the same tires or would a 2ct give me a better feeling in the corner or maybe even a pilot power. i found the 2cts deliverd for 265.

I went with Corsa IIIs. Other than the 'stones it originally came with, I've haven't ridden anything else.
