I found a complete set of nitto 555 drag radial with same fitment for the 135 almost in new condition only 2,000 milles in my dads garage and i put the rear ones, now the car is with no grip on rear,you dont fell the PULL as i used to with brigetone potenza (original tires). I want to know if since the Nittos are 10 years old (from prodcucion date on tire) they loose traction ? or they need to be warmup for real grip? do tires loose quality(grip) over time?

thanks

wow that's pretty old! Probably why they don't grip too well. It is recommended to change them if they are that old, even unused spares that are that old.

+1. Tires degrade over time. Most have a lifetime of 6 years or less, depending on how much natural rubber they use, sine it decomposes at a faster rate than the synthetic stuff.
