hey folks,

picked these pirelli corsa III tires about 6000km ago and they are already worn down. I thought they would have lasted longer, i do alot of commuting, but i also get out to the twisties daily so i thought my tires where wearing down pretty evenly.

fast forward to yesterday. I find a spot on the tire that is down to the metal (other sides actually have a decent amount of tread left which I find odd). how long do i have on this tire before it fails. im a poor college kid so im trying to make it untill friday when i get paid to either get a new set of tires or just throw a missmatch on for the remainder of the season. the bike is my daily driver for the remainder of the season so i need to ride it every day.

- could i ride out the season in current condition or the tire is just to far gone? could I commute down to the city from Aurora safely 1 or 2 more times?

the bike is a 06 zzr600 with a 190/55 rear on it if that makes a difference, ive also droped the pressure today a bit on the rear to widen out the center contact patch if that makes a difference.

As a tire expert by trade...my professional opinion is that any tire with exposed cords are expectable to rust through moisture which will lead to a catastrophic failure. Also If MTO or any officer pulls you over for an inspection they can fine you. The lowest point anywhere on your tire can not be below the minimum legal tread depth remaining for MTO standards.

In short, sorry bro it needs to go!
 
i would still need to ride it to a mechanic and the closet one i trust is 45km away.

regardless of how legal it is or not im still going to be riding on it at some point to replace it

Thats ultimately your decision. Sounds like you already know what you're going to do anyway.....why ask for the advice?
 
well I know it is dangerous and illegal already but I also know of other people who have ridden with tires in way way worse condition then mine and came out unscathed. so basically I would like to kno how long i have on it untill it goes, if i should stay off the highway etc. i dont have the option to tow, or pay some jackass to come to my house and change my tire for a insane fee. im used to paying 30 dollars a rim to change the tire. cant take my rim off and get a ride down to a mechanic either.

and if using a missmatched tire (different brand and tread pattern) on the rear is alright for the remainder of the season because this would be my cheapest option, and seems stupid to get brand new tires with only a few weeks left of the season

I wouldn't ride on that. But it's really easy to take the rear wheel off, then you can just take it to a shop.

Agree! take it off yourself and get it replaced. If I did everything that "other" riders did I'd be dead by now knowing my luck! #Just saying
 
i wouldn't ride on that...my 2 cents i value my life much more then having it blow out...
 
i would go only the distnace you must go to get it changed. no highway. gentle acceleration etc.

there is no specific point for it to "blow".

people have done a couple hundred k on cords and been fine. others have had blowouts immediately.

buy a used rear. get through the season. replace over winter.
 
1. That bike should be running a 180/55, not a 190/55 for the rear.
2. Looks like you scrubbed one side down, either downshifting/locking up rear....
3. Wouldn't run those tires.....
 
IMO, you are asking for trouble if you continue to ride on that tire. Having a mismatch is better than your current situation - no? :dontknow: Personally, I don't screw around when it comes to tires and brakes. If I recall correctly these guys sell scrubs and that will definitely save you some money http://www.bikeyard.com/.

BTW 6000 km is not that unusual for a sport bike tire, you may want to consider a sport touring tire for your next purchase if you use the bike to commute. Michelin Pilot Road may be a good choice for you.

that really depends if you want to die or not...
 
You might be a poor college student but you bought rich man's tires. You can get tires with harder compounds in the centre of the tread and softer rubber on the sides. They should last longer.
WRT riding on those... You think you're poor now? Wait until you see how much an accident will cost you. It will cost you time (away from school) and money (fines, insurance deductable, ambulance etc.)
And it will cost you short term and long term (insurance rates for the next few years).

i got the tires for cheap from reciprocty, i would never have paid retail for these tires. i read reviews on them and people had been getting 5-6 thousand miles off them, so 6000km is a little less then i was hoping to get on them.

i was going to get sport touring tires as they better suit my needs but couldnt good pass up on these tires at the time, thats why im not going out and grabbing another corsa tire to replace it. I need to ride from aurora to rosey toes atleast on my tire, taking it slow off the highway i hope ill be alright

littlesaki - you are most likley correct, had a late night close call with a deer in the road late august where i locked up the rear but still came to a stop safely. i assume thats where its dug in

Tire longevity is not as simple as "oh that's what this guy got"

PSI
driving habits.
compounds
road surface
load
speed
etc....

All factor into to tire life. (its the laws of physics)
 
How were you planning on making it to school once the snow hit?

If (cost of new tire + install) is less than (cost of taking GO to school x projected number of riding days left in the year), then just buy another tire. If it's not, take the bus. If you can't afford either, sell the bike. You don't even have to ask if riding on that tire is a bad idea. You know it's bad, you're just trying to get people to validate a bad decision.
 
Why are you running a 190/55 ? you should be at 180/55 for your bike. There is a significant price difference too from what i remember. That is a liter bike tire, most riders avg about 2500-3000 miles on the ducati board with a 1098/1198 with that particular tire . You got more because you dont have the torque as the bigger bikes. You are probaby better off with like a pilot road 2 that will give you about 12-15k kms on the tire, plenty sticky on the twisties too.
 
I've done over 1000km with the cords showing all the way around the tire (coming back from the east coast), but when I got home, I threw the tire in the back of the car and got it changed. It may last, but with the cords showing, it's damn slippery.

Why do you keep bringing up spending money for only a few weeks left in the riding season? Your tires won't melt over the winter. Fresh rubber makes for a fun spring.
