That was definately a bad experiance you had with ZLOs and it definately will not be the same for everyone using ZLOs. And the roads i drive on are definately one of the worst you'll find. You were unlucky to get a defective tyre but I have had a very good experiance with the ZLOs so i cant write anything negative about it right. I just wrote down my experiance with the ZLOs and hence my recommendation. And i believe the ZLOs are better then Acelere's anyday.
