My husband and I are arguing over whether the replacement tires for my Mustang must be Z rated, and if so, why, if I never EVER drive that fast? Is there a safety factor involved? If they can be replaced with a different speed rated tire, can anyone recommend a decent tire for this specific vehicle? I would be really grateful for any help you guys can give me. Thanks in advance

It is recommended to at least maintain the speed rating of your manufacturer's original equipment tires. Though you won't drive even higher than 80 mph, speed rating translates into the handling of your car. Higher speed rated tires have arguably better handling. On the other hand, if you downgrade the speed rating you should expect poorer handling than what you are used to. It may be a safety issue at a higher speed.

No reason to stay with a Z rated tire on a Mustang. Z rated like for over 150 mph... get real what Mustang needs that? I would stay with a High performance tire... a V or H rated tire would be a better choice. Remember that for the rubber to be able to withstand that super speed 150+ mph it trades away lower speed grip that you could use in every day driving. If your going to race to work at 150 mph buy those Z rated tires, if you drive in a more normal fashion and want to enjoy your car buy a V or H rated tire. The company puts these tires on as a macho thing not because the car needs them....LOOK AT ME, MY CAR IS SO FAST IT NEEDS Z RATED TIRES.

Bender is correct in that you do not NEED to go with Z-rated replacements, but NV99 has a point in that you may WANT to put Z's on.

The rating tells you up to what speeds the tire is capable of handling. Higher rated tires also have stiffer sidewalls so they will be firmer and tend to have less roll, which feels better to most performance oriented drivers.

I disagree with Bender that higher speed rated tires offer poorer low speed grip and as for the macho thing, you would need to be looking REAL close to see the speed rating.

But if you don't push the car real hard and prefer a "softer" ride, go for the H rated tires, or the V's as a compromise. It won't hurt the car, and as long as you don't exceed the speed rating, it won't hurt the tire.

Jay is right on the money, and sorry to say, but Bender sounds like he is still on one...

hi,
i recommend a good H speed rated tire to get a lot longer life out of your tires and still have decent handling, braking, etc...
The tires I have now are excellent, Nitto NT 460. I bought them from tires.com
Another excellent H speed rated tires that several friends have told me about are the Firestone SH 430 which can be bought from tirerack.com. Compare the prices from these two places. They are both very reputable companies that I have done business with myself. You will get about 65,000 miles out of these two tires, especially if you drive more conservatively, not flooring it all the time spinning the tires and burning the rubber. Hope this helped you and your husband out.
