I'm in el paso. These were on my 2007 that was built in winter 2007. Then it had about 500 miles put on it until I bought it this may. (kid who built it, went away to school and it sat in his parents garage). When he graduated, he sold it to get a house....plus his parents said sell it or they would!!where are u located, did u buy them new, how many miles on them? have they been recently charged?
