    I recently purchased a 1997 355 with low miles and plenty of life left in the original tires. Should I have any concerns about the age of the tires and safety??? I drive on the street only no track but I have been known to lean on it a bit!!

    Absolutely positively change the tires. The rubber gets hard and starts to crack after a long period of time. Not only is it a safety issue but handling will decrease as well due to the rubber being hard.

    The correct answer is: yes, after 7 years (or whatever the tire maker specifies, but for some reason the '7' sticks in my mind) you should replace them as the rubber has begun to harden and lose its performance properties. On low mile cars you probably also have flat spots from the car sitting around so much.

    In real life, my tires are at the 7 year mark, with 90% tread left, I drive like you do, and I'm waiting till the spring.

    The other factor is that new tire technology should make the car even more fun to drive. (And tires are probably the cheapest part of a Ferrari anyway. ;))

    I wholeheartedly agree! Not only is 7+ year old rubber dryrotting, it gets hard, loses traction, and also, tire technology improves continuously! It will be the best $1000 performance upgrade you could possibly imagine!!!!!

    Something bad could happen at any speed with really old tires. Change them.

    The tires are Pirelli P Zero's, were they OEM original equipment??? They look new and have no cracking or drying as I had seen on several other cars I looked at prior to purchasing this one.

    Go on Tire Rack's website and learn how to read the tire manufacture date. Don't be surprised if the tires are actually older than the car! If they were replaced, I would still follow the 7 year rule! TRUST ALL THIS GOOD ADVISE!!!!!!! It is always surprising when an old "no dry rot" tire is taken off how it looks like crap ON THE INSIDE!!!!! TRUST US.......THIS IS THE MOST VALUABLE FREE ADVISE YOU WILL EVER GET!!!!!!

    They are 10 years old, you are better off putting the cheapest new tyres then leaving them on the 355. You have got 380bhp!

    Well it would seem new tires are in my future...Any suggestions on brand or size??? Still hate the idea of tossing these but the thought of a problem while exploring the upper rpm limits overides my desire to hang on! Thanks for everyones inout.......

    Can't beat Michelin PS2's for performance, can get in OEM size (rears listed as Porsche) or upsize rears to 295's which fit and perform well if interested in larger to fill the wheelwell. I have OEM's and know several 355's with the upsize. These will transform the car to a handling beast!!!

    I dip my tyres in a bath of Armorall every week. They will NEVER perish that way! ;);)

    Second that. Almost all my tires get a "send off" that way. When I changed mine in the spring I went with the BFGoodrich g-Force T/A KD. I like them a lot. Not as sticky as the PS2's on my 996 but the trade of is the slower wear. I don't track the F-car but in every circumstance on the street, including torrential rains, the BFG's were excellent, and on the lower end of the price scale as well.

    definitley change them. Old tires are no good, regardless of tread life.

    I never thought of that. Do you actually remove the tires each time to do that? It seems like you could rig up a deal where you kinda drive through some pans of armorall once a week and accomplish about the same thing.

    Maybe I should change my tires, I bought an old vette in 1988 and replaced the tires then, they still look new and don't have many miles on them but I did drive it yesterday.
