How long on original tires? - 2003-04 Mach 1 Registry Owners Club

rsnider · 05-08-2009, 08:03 PM

I have an 03 that was built at the end of February. I keep the car garaged 95% of the time. There are not signs of cracking or drying but I worry about the tire coming apart at high speed. I live in a warm dry climate and only drive the car occasionally. The car just turned 23k.

With such limited ultra-violet light exposure should I worry?

I might not understand the explination, but I'm looking for someone with engineering background (or at least a few years under their belt at Discount Tire and a technical background with tires).

I sure don't want to have a mishap at the track or on the freeway.

Can anyone help?

in your hot enviroment id be replacing tires. uv isnt the only killer of tires. heat in general is as the oils and what not in the rubber eventually drys out.

My original Skaterbacks have about 6k miles on them and are HORRIBLY weather cracked. There are 1/4 inch cracks in the valleys in the tread pattern when fully inflated. They were like this when I bought the car last year with 2700 miles on it. I was just waiting for one to come apart on the 800 mile drive home with it.

There was a report on a TV news special a year or so back that said seven years is the max age on tires regardless of the mileage. Not that they will fail immediately but they are no longer safe at higher speeds.

I think this has been discussed before somewhere in the forum because I found out the tires on my 1970 Mach were 14 years old and I replaced them even though the tread look good. I enjoy driving my classic Mach at "high-way" speeds at least once a month.

Tires on my 70 Mach are going on 11 yrs.....they have lots of cracks and are VERY VERY hard....Really need to focus on getting a new set.

Tires on the 04 are still like new and will last forever LOL If you decide to sell your original tires I would love to have one for a spare

I ran 6.5 years with 24K miles on my 1994 GT, I am still on the orginals on my 2003 Mach1 (only 14K miles) garage stored most of the time.
