    The last high speed-rated tires?

    A recent tire thread caused me to do a little googling on high-speed rated tires including the "police pursuit tires" I profiled in a 2003 Corvette Restorer article. In particular I was looking for the 225/70R-15 100V Firestone Firehawk PV41. Much to my surprise I found several online retailers whose Web pages said they were in stock, but it took a call this moring to confirm.

    Starting with the lowest price, the first outfit, which is in Southern California did not have them, but the second outfit in Portland OR had four, so I bought them!

    If you're interested in V or better speed rated tire, this may be your last chance since all appear to be out of production. For C3 owners, google the following terms.

    Firestone PV41 225/70R-15
    Goodyear RSA 225/70R-15
    General XP2000V 225/70R-15

    It's still possible that there is some remaining stock.

    For C2 owner's the W-rated 215/70ZR-15 Pirelli P4000 Super Touring was the pick of the litter. These went out of production a year or more ago, then apparently were brought back with a short production run, and I think a few C2 owners were able grap a set in the last few months.

    There may still be some stock left if you're interested, so google:

    Pirelli P4000 Super Touring 215/70ZR-15

    This may well be the last opportunity to find a V or better speed rated tire for vintage Corvettes. They offer better all around grip and the safety of a spiral wound nylon cap belt that will virtually eliminate the possibility of a catastrophic tread separation, which can happen at legal highway speeds with S-rated tires.

    Given the superior materials and processes used to manufacture high speed rated tires, I consider their shelf life to be at least two decades if properly stored. This would be a cool, dark place away from any ozone producing devices like electric motors if stored off-the-car for future use.

    The same applies on-the-car assuming it is kept in a garage and is only driven occasionally as is typical for most collector cars.

    Yes we got 5 of the Pirelli P4000's in February for the '67 L71. Great tire. My local tire shop was able to get them from the warehouse in Orlando. Even if you can't find them from the big internet tire places, check with your local shops. There may be some still around.

      Duke, good post, thank you.

      So if V rated tires for C2s are going away, does it stand to reason that H rated tires are still available? Or even U rated? Both of those tires would suit many needs as they would allow C2 owners to almost double any posted speed limit......(not recommended)

        Chris,

        Let us know what H or even U rated tires you find. Even us C3 guys, and some of my friends who own former police cars (as I do) want to know.

        Oh, and BTW: my Caprices are speed limited to 149 mph and require V rated tires. What am I to do when they are no longer available? It is against someone's rules, if not the law, to put lesser rated tires on the car.

          H is usually the lowest speed rating that has the critical-for-safety spiral wound nylon cap belt, and I believe there are some H-rated versions of at least one of these sizes still available, but they may not be in traditional US or European brands.

          This thread by me is a heads-up to those who want the best grip and safest tire for their vintage Corvette, but I did not do a comprehesive search of everything that is available below V.

          I only looked for V and higher speed-rated tires in these two sizes.

          My point is: If you ever want decent tires for your vintage Corvette - something better than the common, generic S-rated, with no spiral wound nylon cap belt "van tires", now is the time to sit down at your computer, do some googling, and consider buying what you need for the furture, now!

            smaller tire shops do not worry about the speed rating as i ran into this with mrs clem's impala. sam's club and walmart would not sell me lower speed rated tires,less expensive but a small shop did it with no problem as they know my wife is not going to be bumping up against the 124 MPH governor any time soon.

              Sears.com still shows to have the radials that I bought for my 67 a couple years ago.

              Firestone FR380 whitewall.

              http://www.sears.com/shc/s/p_10153_1...&blockType=L14

              Technically an all season tire, but only H rated.

                The Firestone FR380 is only S-rated and lacks the spiral wound nylon cap belt that I consider a critical tire safety feature. It can save your life!!!

                  I think, at that point, your only option will be to go to a larger size wheel for which there are "V"-rated tires available. I don't think the larger wheel will "upset" the appearance of one of these cars too much.

                    I knew I should have bought a set of Impala SS wheels when they were inexpensive. I just don't think they are in keeping with the image of a former police car, and a daily driver. Maybe I'll have to go for some dubbs like the boyz in the hood.

                      didn't you say that Avon made a V rated tire for the C2's that was DOT approved?

                        Firestone Firehawk Indy 500 215 70R's smooth ride as fast as you want to go in a C2 riding on an original suspension.

                          Yes, I've mentioned the 215/70R-15 98V Avon CR6ZZ DOT legal racing tire before. It is available in two compounds. It is also available in a 205/70R-15 96V (only in the harder compound), which has the same 26.7" OD but slightly narrower section and tread widths.

                          This is probably more tire than most vintage Corvette owners can use, and they are quite expensive, but with a little supension tuning - nothing major, just alignment and adjustable shocks (and maybe a front bar change), and in the hands of a competent competition driver, a C2/3 could pose a serious challenge to a modern sports car in the hands of an equally competent driver.

                          The UTQG rating is 80AB, so this tire will probably deliver about 8-12K mile of normal road driving, and it is as good in the rain in moderate temperatures as most other tires. Of course, if you spend a lot of time carving canyons or running track events, life will be less.

                          The B temperature rating combined with a V speed rating is very unusual, but this tire is designed to retain heat. Optimum grip on DOT legal racing tires is usually achieved in a tread temperature range of 180-200 degrees F. These temperatures can usually only be achieved on a race track, but even at the lower tread temperatures typical of road driving, DOT legal racing tires have grip far beyond anything most have ever experienced.

                            Does anyone still sell high speed rated tires in a 205-75 size?

                              I have never run across a 205/75R-15 tire that was better than T-rated - maybe U, but that is not a common rating - so none have the nylon cap belt. They're all van tires!
