Just wondering when anybody is thinking of putting their summer tires back on. I have sumitomo htrz II's sitting around waiting for warmer weather, but I can't remember above what temp you're supposed to use them. I know if it gets too cold the tire will suffer, but I'm really clueless as to how cold is too cold..

any ( help / suggestions / telling me how i'm wrong ) would be greatly appreciated, thanks

I use my summer tires year round............

 

craziness .. i'm bad enough in snow even with all season's on.. i'd be dead by now if I left the summer tires on year round

 

I say wait till you know for certain that there won't be any more snow. I learned my lesson today.

 

It's going to be slightly different from model to model, but the temperature that's best for "summer" compound tires is generally 10 Celsius or 50 Fahrenheit or above. It's not "bad" for the tires as far as I can find out, it's just that they have less grip and tend to harden below that, which is why sometimes you read tire reviews where the person complains that the tires are hard and bumpy until you drive around a little bit (presumably because they warm up).

Besides trying to find time and waiting for good weather to do some repairs, I'm waiting until the ambient temperatures are going to stay at or above 10 C for most of the daytime.

I've tried looking in Almanacs and stuff like that, but they only go by month, so they're pretty useless...

 

cool, thanks..

 

When it snows I drive my winter car (minivan)

 

heh......I used to do that too
