When brand new these tires produced strong vibrations at speeds above 50 mph, as well as when accelerating from rest. Returned 3 times to vendor to rebalance them, even did a road-force test, and never any improvement. Ended up rebuilding the car's front end in hopes of smoothing the vibrations with little success. One tire had 2 very small pin holes, which, within a month after purchase made itself evident because the tire was going flat. Never saw a nail or anything in the tire, and the holes were literally less than a millimeter in diameter, so the holes looked very much like a manufacturer defect to me... but since I had already been back to the vendor 3 times in the first 3 weeks for balancing issues, I decided to avoid them for the pinhole issue (as the relationship was becoming ascorbic - i.e. i didn't want to be labeled a pain-in-the-ass customer). Not long after the pinholes were discovered, a second tire also began to lose pressure (again, no sign of any nails in the tires) - they were losing probably about 10 psi per week - so my routine became something like: fill to 40 psi, and 2 weeks later, refill back to 40, and don't forget, or you'll have 2 flat tires... which eventually did happen. After a can of fix-a-flat sprayed out the sides of the tire, I slapped on my spare, and I was faced with the choice of paying $30 per patch, and needing at least 2 patches... and hoping that this would fix the flat problem... or give up after 18 months and replace all 4 tires. I ended up choosing to replace them with 4 Falken SN211 tires.... and my first time on the interstate, there was no wobble (not even at 80 mph). The wobble was not the car, it was always those damn tires. What a waste of money! In conclusion, one would be wise to spend an extra $100 on a better tire... unfortunately, when I went in for service, I was never given an option on tires, and was simply promised that my car would be fixed... and now, finally, it is fixed. So, yes, by my experience, you may as well throw you money in the trash and set it on fire - it is essentially the same thing as buying these crap, unbalanceable, tires.
