Different Speed Rating

[bigd6983]

i bought some kuhmo tires to replace my back ones because the tread is next to none and the passenger side has a major leak, so i bought the tires in mind that in less than a year when funds permit i was going to buy a whole set of really nice ones, this is only temporary and the tires werent expensive and i couldnt spend the money I wanted on the tires. well the nittos i currently have on have a v rating and the kuhmos have an H rating. Went down to costcos tire department and they said they couldnt mount them because of the different ratings but he suggested a smaller shop would not turn me away. I dont see a problem putting the tires on, but is there something I dont know, remember I dont plan on keeping these on the whole life of the car, so keep that part out of mine.....

find a different shop. V rated tires are good for 150mph, H rated for 130. Neither of which our cars will reach. I don't see why the won't mount them.

yea thats exactly what i was thinking, and yes im taking it to a shop in the morning........i knew the v rating was way out of league and i knew i would never hit the H, and i didnt think there was a problem the two being on the car......but whatever.....problem solved........thanks for answering grouch

It's not so much the amount of speed the car can go, but the stregth of the tire itself.

If a tire can take speeds of 130 MPH, it's not as strong as a tire that can take 150 MPH.

You also have to look at the traction rating and temp rating. If one tire you replace has a lower tracion rating than the other 3, it could become a problem with rain, standing water, sharp turns, and so on. Your Nittios probably have a higher rating than your replacement Kuhmo's.

"H" isn't that far from "V" so you shouldn't have a problem. Might feel a little different at highway sppeds. If you have "V's" and put on a "R" or an "S" then issues will rise.

the ecstas........like ive said they are kinda temporary......and i only paid 20 bucks for each.......I made sure they are directional like the nittos just so there was no problem there.......
