OP, as far as a nice set of all-seasons go, I've been very happy with the Yokohama Advan S.4 tires I've got. They grip really well in the dry and wet, and do a decent but not amazing job in the snow. (No all-season tire will be "amazing" in the snow.) I've also heard good things about Continental ExtremeContact DWS. I was going to get those myself, but they were on mega backorder at the time I needed them, so I got the Yokos instead. They cost a few $ more, but realistically, I have no regrets, as they perform well and still have plenty of tread left after 22K miles.

 

Its actually within 3% not .8%

245/35 and 235/35 is 1.1% difference therefor safe for the time being. Im planning on switching rears to 235/35 sometimes next week.

 

Dude just change all the tires at the same time. Why risk damage with calculating size percentages? Its not worth it.

 

Do not get the Continental DWS!! I got a set less the 2 years a go,25.000 miles and they are shot!! And very noisy! Never again

 

Wow, I guess I'm glad they were out of stock when I wanted them. Like I said earlier, my Yokohamas have been good for me.
