Slightly different tyre question

[vickster]

Riding my Whyte the other day for the first time in a while (happens when you succumb to the N+1 imperative ), the rear end kept sliding going round corners

There is a fixed rack on the back of the bike, trunk bag with expanding panniers, wasn't carrying that much weight (no more than I usually would on the roadbike commuter). Stock 28mm tyres (Maxxis Detonator). Rear was softer than it should have been.

A tyre issue, lack of air issue, weight distribution issue, other? Certainly a bit disconcerting especially as this is meant to be the wet weather bike with disc brakes

Thoughts?

I would suggest lack of air this will result in a creep around corners, to much air and it may bounce and bump around a corner but shouldn't slide.

more wind for @vickster i think

I have pumped the tyre up now, will ride it tomorrow. Can't use the Joe Blow with gauge though as when Evans changed the inner tube, they used one with the shortest valve possible!

PSI is funny, sometimes its best not to have too much so more of the tyre is in contact with the deck but too little and the tyre is too flexible and feel like its sluggish and sliding

Sounds to me that that might be part of the trouble, most valve stems I have come across during my cycling life are more than long enough to fit a track pump adaptor on, maybe your inner tube is not seated down correctly. Sometimes If the hole in the rim tape is not correctly aligned up it can restrict the vale stem protruding through the rim. I would remove the tyre and check the tape is fitted correctly

I had the same problem last week, it felt like the tyres were made from play doh. Put some air in and everything was fine
