noobie question front tire slipping?

[amazinkat]

I just noticed today when I am going around corners at normal sppeds it feels like the front tire wants to slip right out from under me. What could cuase this? My rear tire was low the other day had like 20 PSI so i pumped it up to 35psi. I had the front tire at 35 also. I now let 5psi out of the front so now its 30psi.

Will this fix whateveer is going on? any help would be great. Thanks

how old is your tire? and what brand is it? tires get hard over time. even if theres tread left they may not stick like they should alot of heat cycles on a set of old tire will harden them over time increasing the feeling of the FE sliding out.

its a metzeler 120/70r 17, not sure about the age I just got the bike about 2-3 weeks ago.

I'm 220lbs and run my tires 36 front 41 rear, you may have a cupped front tire due to running at low psi. This may be what you are feeling when you turn.

Either cupping or old tires. You can check the date code on the tires and if they are more than 3 years old replace them. I never run my bike tires more than 3 years no matter the tread depth. After that amount of time they start to get hard and will start to slip. Also you have to be aware of age cracking/checking also. Better to replace and be safe than to push it and have one come out from under you or blowout at the worse possible time.

Just my 2 cents on this one

Or it could be technique ......

i agree with the old tyre thing - i had a bridgestone battlax on the back of mine - it was practically an unused tyre - all tread left on it as new - but it was old - digging it in to a corner i may as well have been going over oil on the road - and acceleration used to spin the wheel without gripping - new squiggy rubber sorted that out - - 20psi sounds low deffinately should help a little pumping them up

cool thanks guys.

As to tire pressures, start with the ones on the swingarm and work from there.

I'm not sure I still have to look at the date on tire. Would an out of date tire just start doing it overnight?

Thanks for everyones help on this

Recheck your tires to make sure you didn't pick up a nail or screw, and causing a slow leak. If you are running Metzlers, try bumping the front to 36-37, and the rear 39-40, and see how that affects the handling.

[amazinkat]

ok, diavolo I will do that!

It starts pretty quick but usually you get small warnings for a month or so first.

i aired them up then went for about a 100 mile ride today and had NO Isues. I am still going to replace both tires. Are Metzlers a good tire?

[md86]

yes
