I had P600 in the front and in the rear for over a year, before I put on "two" sets of Yokohomas AVS on my DeLorean. Yes, I had two sets of Yokos AVS on my DeLorean in the last three years. The Yokos' threads don't last long. They are great riding tires ... but they last long. It was four years ago in the month of May 1998, when I needed new tires to attend Ken Koncelik's first DeLorean Show held at Cincinnati, Ohio in 1998. I wanted to replace my Dunlops that I had for little over a year and I wasn't happy with the ride nor its handling abilities, besides the Dunlops I had, they had very little threads left and I also need tires right away as to attend the show. I wanted a set of Yokohama's AVS and they were not available, not even form the US Yoko Distributor that I called and they claim it was on the freight boat from Japan and due to arrive in mid July of that year. The Tire Rack and many other tire distributors did not stock any tires of the same manufacture for the front and rear sizes. Either they have the fronts or the rears. There were no tires at all to be found, from any tire distributors to fit the DeLorean. So, I desperately did some research and found that the Pirelli P600s were available for the fronts and the rears from a very large tire center some 10 miles from me. The P600s had different speed rating, but that is okay for my usage, beside they were cosmetically all the same. I had ordered them by phone and had them mounted on my DeLorean immediately when they arrived. After driving the P600s a year and a half, I had replaced them with Yokohama's AVS that were available from PJ Grady. There was nothing wrong with the P600s that was on my DeLorean, I was just curious as to the ride of the Yokos which everyone was "raving" about on the DML News. I wanted to experience this "rave" for myself. The Yokohama's AVS have the same high speed rating for the front and rear ... the P600s are not...only the rear are high speed rated and the fronts have a lower speed rating. Folks, don't worry, unless you have a different motor than the standard PVR, your DeLorean will NEVER exceed the lower rating of the P600s. The Yokohama's AVS looks rounder-"fat," while the P600s are "squarer" looking and its "visual" flows well with the contour of the DeLorean ... IMO. P600s and the Yokos are both good tires. I personally like the looks of the Pirellis P600s and the ride is slightly different then the Yokohama's AVS. The Yokos ride is softer, slightly quieter and holds the road "just" a bit better in the rain. The P600s is great on dry roads and slight better in the snow, from two to three inches ... the Yokos are NOT good in snow at all... not even in 1/2" of snow. I have driven many long road trips, at times for over 18 hours per run on both of these brands of tires and the conclusion is that they both have different qualities that I can live with... The P600 makes the DeLorean run and handle like a sport car, harder stiffer ... the Yokos yields a nice "rich-luxurious" ride (Cadillac ride). The Yokos and PJ Grady's shocks are a great combination ... given the DeLorean a great ride! BUT, on my next set of tires... I will fit them with P600s again. I like them just a lit bit better ... for that sports car "feel" and especially for the winter (emergency) snow travel. I don't like slipping in the thinnest of snow. Again... to each their own...... I hope this helps. Kayo Ong #5508 Lic 9D NY [Non-text portions of this message have been removed]
