When my previous front set of Goodyears were at the legal limit and I was short of cash, I searched for a budget tire to get me through the winter months thinking that I don't push the car hard on cold wet roads anyway. These Rovelo RPX998 had quite a few good reviews so I took a chance and put 2 on the front of my CLK500. One warm evening, I made the most of some quiet country roads and opened up the throttle a little. The CLK500 has a 5.5L V8 and well over 300 BHP. Although I wasn't pushing the car to it's limit, I was very impressed at how these budget tires seemed to be just as good as the previous high quality branded set they replaced. Great feel and feedback (although with Mercedes power-steering). Very good grip and road holding. I had the 92 Extra Load spec so the side walls should be stiffer than standard. Keep in mind, the Merc is rear wheel drive, and the 2 Rovelo's were on the fronts so they only had to deal with steering and didn't have to handle putting the power down. But they have really impressed me, even on cold, wet roads they seem just as capable as my old Goodyears. And when you consider I bought 2 (fitted) for the same price of 1 Goodyear, they are fantastic and I would highly recommend them. A very good quality tire.
