^Narrower tires are better for snow. 225 - 235 is fine.

If you're getting Blizzaks, shouldn't you get a 2nd set of wheels? Unless you're willing to do a full dismount and remount of tires, twice a year, but that seems like a hassle to me. I'd rather have 2 sets of wheels than do that.

That's what I've read before too.

Wouldn't 225-235 be under-tiring the wheel quite a bit (rears)?

No because because it's still with the tire's acceptable width range.

The only thing it could affect a little is the odometer.

So what's the narrowest you could run in the rear?

I have 2 sets of the OEM 18s. I use one as my winter set.

^ also does anyone what the narrowest tire is that we can put on the front?

I'm not sure because I never tried running non-stagger on a stagger setup for winter.

I just ran the stock sizes.

I was told you can run the same size as the front all around and it should be fine, which is what the AWD model does anyway.

Yes, correct for AWD you can since the car was designed to run all around the same.

The RWD, not quite. Youc can technically put 225's in the back to make them all around but then the odo would not be quite accurate the revolutions is off.. Unfortunately the spedometer cannot be reprogrammed to take in account the different tire; if it could I would probably would consider going all around.

You can manage but have to be careful. I definitely recommend proper winter tires because it will make a significant difference.

When I had the 07 250 AWD, I was on A/S season too but was able to control the car being careful since I'm used to driving in the snow. At times, I gunned it to make the car slip to know it's limits of what you can and cannot do.

When I had my AWD is250 with all season tires, I had no problem driving in snow and on icy roads. We don't get much snow in Seattle area, but when it snows the roads can stay icy for long periods.

I also have a set of Dunlop Sport Maxx tires on my RWD IS350 and I assume I need to get a set of winter tires, but I don't want to get another set of rims. Is there any downside to mounting and dismounting tires on rims other than the cost of mount and balance? Is that going to affect life of rims or tires?

About about 2 years ago, there was a winter where SR-900 in Issaquah, was basically became literally became a sheet of ice (the snow crews didn't show up yet either!). So icy the cars were moving at idle to 5 mph at least because. Moving from a stop you instantly slip. It was a good way for me to test WOT to make it slip right away that the car literally started beeping and was cutting the power.

That was with the AWD on all seasons. Probably woudnt' of slipped that easily if I had Blizzaks on them. Now since I'm on RWD, I have Blizzaks for winters.

So, do you have another set of rims for your bliazzaks or you just mount them on your current rims? I probably will get some bliazzaks but don't wanna get a new set of rims...
