Can i put H speed rated tires on my car, when Costco's system says it supposed to be V rated?

I have exceeded 100mph. On a public road or highway. For some length of time, not just a quick drag race through a deserted part of town on a Sunday afternoon. As often as not it was at night. The 1965 New Yorker (26 years old at the time) with bias ply tires was a bit exciting. The 1969 Olds NinetyEight Luxury Sedan was a smooth straight quite ride.

Mountainbike,

Me, too. On 3 separate occasions with 3 different cars.

I’m glad that I survived being young and dumb. I drove several Austin Healeys and Jaguars and a Datsun 240Z flat out for many miles. My last and stupidest high speed drive was on a 900cc Kawasaki.

As for tires in the 1960s I recall ‘red line’ tires that everyone put on their high performance cars.

100+ in the middle of Nowhere South Dakota, interstate, ruler flat, no other vehicles or animals in sight.
Just wanted to see what it feels like. Dropped back to 85 after a few minutes.

A guy I worked with said he drove his Z28 Camaro 6-spd all the way across Kansas in 6th at night with his right foot planted. He was disappointed it only went 130-135 mph. I didn’t tell him he needed to be in 5th to reach the advertised 160 mph. He was crazy enough to try it.

I had a Suzuki sport bike from just west of St. Louis, MO to Rolla with the speed reading between 110 and 115 MPH all the way. DUMB and I do not even want to know how much the speeding ticket could have been.

I’ll just say that it was under the most controlled circumstances possible and leave it at that, and that the statue of limitations is up.

I guess based on this very unscientific survey that it’s safe to say we should all get tires rated well above our normal highway speeds… at least those of us who frequent this forum should. One blowout above 100 mph can be deadly for the average driver. And I noticed that Danica Patrick didn’t post (bummer), so I’ll assume we’re all drivers of average skill levels.

@the same mountainbike, I have exceeded a 100 MPH on pubic roadways a few times. I’m a laid back casual driver so I don’t make a habit of high speeds anyway.

A 125 (at night) in my '68 Roadrunner and on bias ply tires…

A 110 (at night) in my '59 Corvette. (Boy, there’s a story behind that one…) :wink:

A 117 on a BMW motorcycle.

A shade over a 100 (at night and very briefly) on the same BMW. (Story on that one too…) :wink:

I’ll bet most of these high speed runs were made with the tires that came with the (used) car, mine were. This would support tire dealers policy on matching the vehicle manufactures tire specifications.

One could sign away there responsibility with regard to usage of the vehicle, never to exceed 100 MPH and not to use the vehicle on a track. Six months later the new owner might be a 17 year old speed freak.

I can only speak for myself, but mine have all been made with tires of a Z, V, or W rating.

@"the same mountainbike"‌ I’ve gone over 100 many times, but then I like to put my car on a race track that I go to from time to time.

I remember back in high school trying to hit 100 on public streets (back country highway) because I was a stupid teenager, but my dad wasn’t into cars (or more accurately, he wasn’t into spending any more money than he had to on cars) and so his slow piece of junk couldn’t get over 75, and it shook like an earthquake even then. :wink:

Shadow, you’re doing it the smart way. A tip of the hat to you.

Back in the good old days I worked at a tire factory and was curious about the test wheel that seemed to run continuously. The man who loaded and operated the wheel said that tires were run through a series of tests at increasing speeds and if they survived all the required tests they were run till they failed by increasing the speed until the wheel maximum was reached and if they survived that the pressure was dropped and then run at maximum speed. A cheap off brand tire labelled Impala seemed to be the all time champ on the test wheel. It never failed until well into the abuse phase. The tire was a plain blackwall generic looking tire with nylon cord. The factory produced the red line tires that were labelled Patrol Pursuit and they must have passed all the required tests but the Impala always seemed to win.

ank, as long as you won’t exceed the rated speed of the H rated tires, everything is fine.

As you might know here in Germany we can drive as fast as we want on the Autobahn (apart from some restricted areas) and it is absolutely common and allowed to use tires with a lower rating as winter tires. We just have to put a sticker on the dashboard, saying “Winter Tires - max. 210 km/h” (f.e.)

My BMW needs W rated tires, but currently I’m driving H rated winter tires, and believe me, I’m almost always driving as fast as possible. :slight_smile:

There’s also no higher abrasion/wearout or something like that. But check for the Loadindex, this value has to be accordingly!

Me thinks OP has left the building.

Those areas of unrestricted speed are becoming less and less common . . .

And that doesn’t help OP anyways

And, as Volvo said, I’m sure OP is LONG gone
