Default Dunlop Wintersport 3D H vs V rating

Those of you who run wintersports, are you using the H or V rated version?
Is there going to be an appreciable difference or not?

I'm going to be mounting mine on 16" rims if that helps.


Thanks!

I am running h's on 16s. I chose them because the were 10 bucks cheaper a tire. The top speed is still over 100mph so just realize you are on snow rubber and don't drive triple digits like a mad man and you will be ok. If you can't do that then it would be worth it for the V's. Although I would still not advise driving triple digits like mad man on snows.

the carcass is usually stiffer with the v rated tires.....usually better with a heavier car on dry roads

H's here...unless you plan on doing extended periods of 130mph (H speed rating) save some coin and go with the H rated WS 3D's. Slightly softer sidewalls on the H rated tire will give you a more comfy ride as well.

Nice. Good purchase. I just mounted mine like 2 or 3 weeks ago. I havn't got to use them in the snow yet I can't wait. Good call on going with deticated winter tires and wheels. Not to start looking for some new summers. Lol

3d H's on last week. theyre still in good shape after 1 winters season. they are a good snow tire, but just like DKT-GT said as long as your not going in the triple digits your fine. I mean, it's a snow tire! i don't do over 80ish with these just because i dont feel as confident as with a summer tire 070's, Star Specs....etc...

this is the only snow tire ive ever driven on with the STi so i cant really comment on how well they perform vs others. However, i am able to control the car easily on snow and ice. acceleration traction is not a problem with the AWD, but stopping is still a little sketchy... not much, but a little.

I would buy these again, and i think youll be happy with the purchase.

they are by far the best handling snow tire i have driven on. cant say i have driven on other high performance snows, but compared to a blizzak its night and day.

Hello Everyone,

Thanks for the replies even though this isn't my thread. I read this thread yesterday and was confused. I'm looking to get the Winter Sport 3Ds and didn't even know there was a difference.

I just wish tires were not as expensive! $637.12 shipped for all 4 to my house

FWIW, most of the published tests are with H-rated variants.

Granted, there's still the possibility that there may be differences between tires marketed in the European market - where those tests are conducted - and the North American market.... Also, there's the possibility that differences in sizing may also contribute to observed differences as well.

Those, unfortunately, cannot be controlled for, as they are factors out of our hands.

Me?

My specific end-goals were to increase my safety-margins in wintry conditions, with the caveat that I did not want to sacrifice any more clear-roads capabilities than I would see with a typical UHP or HP all-season tire.

I therefore went with the V-rated - if only for the reason that, by logic, they should be only a stone's throw away from their "all-season" cousins: that their harder compounding (compared to their H-rated variant) should provide somewhat better feel/accuracy on clear roadways and highway, as well as perhaps a little better objective performance under such conditions - and at the same time, hopefully a bit better durability/longevity.

I do wish there was some data to either prove or refute that possibility, though.

FWIW, CR gave the V rated 3D a snow acceleration score of "excellent", and an ice braking score of "good". They gave the same scores to the V rated Pirelli Sottozero 240 Series II, and Toyo Snowprox. The usual caveats about CR tire testing apply.

how much harder is the sidewall on the V rated vs the H rated? I'll be also using this tire for rally cross events.. (need stiff sidewalls to prevent jumping the bead)

i dont think anyone knows for sure what the differences are. people are just guessing that the sidewall is stiffer or the compound is harder. i doubt you could run the h on one car and the v's on an identical car and have anyone tell them apart.

yer way wrong here


the v rated tire is a higher load rating....therefore it HAS a stiffer carcass

there is no way to make the 'same' tire, one with a sl and one with an xl load rating and have them NOT be different in this way

the compound is almost certainly the same, the carcass is NOT

and it was real easy to tell some tires of different load ratings apart just by sitting on them

you cant just sit on a tire and tell how its going to handle. some squishy feeling tires handle better than some that feel stiffer. load index and speed rating dont tell you how a tire handles.

I guess being the shop manager of the states biggest custom wheel and tire store for 7 years doesnt qualify my opinion in the presence of an e-thug with a piss poor attitude. Until i get to be as smart as you ill suggest to tirerack that they rate tires based on sitability to further educate the uneducated mouth breathers like me.

Default avg temperature for winter tires?

I live in NC and drive up to the mountains for weekends for skiing / boarding. I drive 2 hrs to the mountain, most of it by interstate or 4-lane highway.

Additionally, the average high temperature in Charlotte NC during the winter is in the mid to low 50's F (lows is the 30's F). Between the high avg temp's and the interstate drives to the mountains, I have wondered if the 3D's would wear quickly. Given this, I wondered if the V rated tires would last longer...

We have enough snow / ice in the mountains that the winter tires could probably be justified.

Theoretically V should last longer than H, based on assumption that V have harder compound than H. It may or may not be true.

I think that 3Ds (or any performance winter) would wear normally in your range (mid 50s - low 30s). Probably similar to High Performance All Seasons. The thing to watch would be the tread depth when you head to the mountains.
Snow tires have snow tread wear markings (usually 6/32"). Their snow capability greatly diminishes below this tread depth. It is the same problem with all seasons.

I'd love to have a set of H-rated 3Ds to cross-compare (any manufacturers/distributors listening? ), but alas, I'm (very sadly :redface a real person, with real financial limitations: besides, my wife would kill me if I got *another* set of winter tires.

Logic would say yes, but that's all theoretical.

The only thing I can say is that I've got somewhere between 10K to 13K miles on my V-rated 3Ds (225/45/17 sizing), which I've abused the hell out of, these past 4 years, during the warmer parts of the transitional seasons. They are currently just above the "snow platforms" or "winter wear bars," which are at 6/32". I really like to have fun during the warmer/clear transition months - so I'm really pretty hard on these tires.

FWIW:
