I have been riding the same road bike, a Fuji Espree, for a few years and am very used to it: I used to be able to ride it without hands on the handle bar very easily, take 90º turns in city streets because it is well balanced and responds in a predictable way.

I recently changed the old Strada-K Forte tires to new Continental Ride Tour Extra which have a more square profile, deeper grooves.

Since then the balance of the bike has felt off: As soon as I remove my hands from the handle bar, the bike starts steering to the right and even with my hands on it, turning feels harder. I'd like to find new tires that won't have that same effect but am not sure what feature is causing this? My intuition is that the more square profile is causing, do you think that is the case?

  • how worn were the old tyres? I find the rear tyre to square off with wear naturally, while the front stays more rounded. – Criggie Jun 16 at 20:28
  • I have a hard time imagining the tires would explain it. Is it possible you didn't put one of the wheels back in straight? – Adam Rice Jun 16 at 20:47
  • I triple checked that the wheels were straight. And it is more the way the bike responds to a shift in balance than being offset completely – Just trying Jun 16 at 22:36
  • What width was the tyre? Also, worst bit is, it's not even square, it's more like triangle profile. – abdnChap Jun 16 at 22:41
  • old and new were both 27 x 1 1/4 – Just trying Jun 17 at 16:56

I did the exact same thing a long time ago. I wonder what width tyres you used?

Basically, I had a touring bike which I used for "rough" touring, and used the 38c version of this tyre.

It was fine at lower pressures in rough roads.

I then bought a set of 25c versions for a winter road bike. Horrible! These, tyres are not designed for smooth roads and high pressures. If someone doesn't understand this problem, basically, the tyre has no smooth corning edge. None.

Just replace the tyre for something more friendly.

We can recommend tyres for specific scenarios, but you haven't mentioned the type of riding or your preferance in setup.
