There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Are there any tread wear indicators on Spyder tires?

Hi Dave, there's actually a whole heap of threads discussing this very question if you do a bit of searching, even some with pics so you can see exactly what I'm talking about, but to answer your question, YES! If they are the OE spec Kendas, there will be a little triangle embossed on the sidewall to show you where to look for the tread wear indicators, which are little bars staggered across each of the deepest grooves in the tread face. When ANY those bars are within 1/32nd of an inch of being flush, or worse, actually flush with the surface of the tread blocks, then it's past time to fit new tires! :lecturef_smilie:
However, be warned, there are a few other bars across those deepest grooves, only generally these 'other' bars have a ribbed surface (if you get to see them before that gets worn off!) These 'other' bars, which DO NOT have the little triangle embossed on the sidewall/very edge of the tread adjacent to them ARE NOT tread wear indicators; they are there to help stabilise the grooves & tread blocks during cornering and to force any trapped water, slush, or ice out of the grooves as the tire rolls & anything in those grooves gets forced ahead of the contact patch.
So on the OE Spec Kendas, if you can't find the little triangle on the edge of the sidewall adjacent to the bars in the grooves, it's not likely to be a tread wear indicator! Other brands of tires might use other symbols &/or indicators; some even have 'Tread Wear Indicator' or something similar cut into the raised strip of tread down the middle of the tire and that slowly wears away until it says something like 'Replace Tire' in that raised centre strip of rubber; but generally, tread wear indicators will be clearly marked somewhere on the edge of the tread/sidewall to show that's what they are! :thumbup:

Center wears first. I changed it when the center got down to the wear bars. Air pressure does not seem to matter much.
The Kendas are soft and the center expands out at higher speeds, even if you lower the air pressure. It causes the center
of the tread to wear faster.
Only have a picture of the rear. Have not changed the front tires yet. They seem to be wearing more evenly.
This is the OEM rear tire. I put a different tire back on it.

Kenda's are medium soft .... what causes them to " balloon " above 40-45 mph is they are made with a with " carcass ".... you are correct about the PSI though. over the years every psi imaginable has been tried in the rear tires and their is no magic amount..... I have decided that as far as the front Kenda's wearing better is there are two of them, since they are much narrower the " carcass " doesn't deform as easily, so IF you have good alignment they will wear evenly ( even if you don't rotate them as recommended by BRP ) ........
