they are fine as long as you dont get stupid with them they will brake loos on a 3rd gear roll on me though in the wet

lol gotcha

If you find a tire that is good at performance in the summer and goes in the snow call the tire companies because you will be rich. You are best off with a dedicated set of each or suffer with no seasons. A goof performance summer tire will likely be brittle in the winter and a good performance winter tire will burn up in warm weather. You drive something like a DR in the winter you are taking your life in your own hands, my 555R's never had an issue although I did very little low temp driving, but I know of several that have chunked and one that even came completely apart. Having said that my 2 choices

Summer/Rain
Nitto NT-05

Winter/Snow
Dunlop Wintersport M3's

I dont think dunlop makes them in a 245/16

will 255/45 or 255/50 fit on my 8.5" stock rims?

depends on the brand check under the specs on tire rack

i preffer blizzaks for strickly winter season. they were AWESOME in the snow on my buddies Z28. drove threw a foot of unplowed parking lot like we had 4wd. but they are all right. get one tire for summer and one for winter. i just never drive mine in the snow anymore. so i have one set. good luck

ya i got lucky with mine and i also kind of didnt have a choice lol...i also did not find out about the temp rating on those till months lata...will i do that again ummm no hahaha

Honestly mine were on the car in the winter, parked in the driveway stuck in 2" of ice and they are still going strong. I keep them indoors now though.
