few newb tire questions

[R6Rupture]

is it safe to use a old pirelli supercorsa front tire with a new diferent type of rear tire, like a pilot power?i think the front is fine, theres losts of tread but ppl are saying its gone through too many heat cycles??i dont have a picture of the front but this is the rear, they both look like that.the middle is stained white their not dirty and their slick whatever that means.?thats what im woried about.il get a set if i have to its no big deal i just dont want to waste money if the front is fine.

Personally, I would say that yes, it's safe to do it. I mix tires on a regular basis with no problems.

I wouldn't do it.. but its your bike, not mine.

It's really a matter of margins. If you push your bike on the street as hard as one might at the track, then no way would I mix tires like that. The other thing is you don't want more grip in the rear than the front can handle (think front wash-out). If you take it easy until the front gets replaced, it should be OK.

My original concern about the pic of your tires is that they look hard and slick like they've been damaged by heat cycles. That could just be the pic, though. How old is the tire you would keep? There are date codes on the sidewalls if you can decode it. It that tire is 3-4 years old, replace it especially if the bike sat outside all the time.

i have the same tires mounted and they dont look that glossy...does look like it has some street miles though. looks a little slick, so i'd consider what ray is sayin....always better to replace them and be confident than to bin it.

New tires are never a waste of money.

track heat cycles can kill a tire and make it very hard and slick, even if there is alot of tread left. If you can see the tires and they are turning a blue-ish color, they may be fine for easy street and highway riding, but not for any hard twisties
