I have pirelli diablos on the front and rear. do i have to get a new set (front and rear) or can I just get another rear for the next time around? | ||

Rear is fine, just try & not mix brands. Also never ever mix bias with radials. | ||

I assume you've actually seen and felt his front tire then? XB's are very sensitive to tire wear. Rub your hand backwards along the front tire. If it feels wierd, I would replace it too. How many miles are on it? | ||

Mookie - what M1 said - it all depends on how worn your front tire is. In general, fronts wear less than rears - especially on the roads you and I live on. Chances are your front is still in good enough shape to forego it this time around, but I would still give it a good once-over. Make sure there is still enough tread, that there are no nicks or grooves in it, etc. | ||

ok. the tire is fine then. my rear was fine until i decided to do 1200 miles in the past week. theres only about 1000 miles on the front and rear | ||

The wear bars are a good indicator, however if a tire is cupped severly then I would replace it. | ||

My front Pirelli looked nicely scrubbed but absolutely no sign of any of the cupping or feathering found on the Dunlop. IF I hadn't been changing to a sport touring tire I could easily have gotten away with just mounting a rear Diablo. | ||

Anyone have a picture/illustration of the mysterious tire cupping syndrome? I *think* I understand what this means, but I need to visualize... It's like this, right? Yes, that's a cage tire, but it works for the point of illustration...  TIA, Chris | ||

Basically cupping is where some of the treads are lower than others in a rythmic pattern. I guess the best way to describe is they generally match the shape of ocean waves coming onto a shore but the waves are only 1/16" high and each tread curves similar to the backside of the wave as it approaches the shore. | ||

Thanks Matt...looks like the pictures in my post above match your description. CHris | ||

Its just that on a motorcycle tire its not quite so visibly obvious. It is detected by running your hand counter to the rotation of the tire. Often times if you run your hand in the same direction as the rotation you won't feel it. So start with your hand laid across the tread at the front of the fender and slide you hand towards the ground along the front of the tire. If your motorcycle tire is cupping or feathering you will feel the tread "bite" into your hand. Or a roughness that isn't there when you run your hand backwards. |
