|
|
On my 57 daily driver I just switched from 135r15s up front to 155/60r15s (wow what a difference). Set the pressure @ 18 psi, visually they look low on pressure, driving they feel too high. The tire are Achilles Atr-k Economist at $85 usd for the pair I couldn't pass them up.
For those running 155/60r15s what tire pressure have you found to be the sweet spot? |

Me, I'd try dropping them to 16 or 17 and see what they feel like. I'd not go any lower than that though. Yes they may "look" underinflated, but with the more rigid structure of radials, they are inherently more rigid overall. _________________ Andy T.

I do not know how to fix this. All I can say is it all works fine for me with what I use, Firefox. |

60 profile tires usually have a stiffer side wall.
Just curious . . Are you running gas shocks in front or standard oil shocks? |

Running standard oil filled shocks, standard width adjustable beam, original rims, and a single set of caster shims. |

All of the answers above are correct.
Check that something hasn't seized up in the front.
Honestly I let mine sit for a few years without checking tire pressure,
It drove weird one day, I found the front tire pressures @ 10 PSI _________________ Good Luck
