So I have 18x9.5 Grid's and I'm lowered on Swift springs, what size Blizzak's would be smart to get for this kind of basic setup?

 

Narrowest tire best for ice/snow traction. The WS80 in 235/40-18 will fit a 9.5" wheel fine. Also a good size if you're dropped.

 

I've always ran wider tires.......... I'm a bit old school.

 

Why not get a second set of wheels? 18x8", +30 and 225/45/18 tires?

 

Since I have to take off the wheels in order to cross rotate them anyway, I figured I'd just re-use the same rims.

 

Are you mounting and unmounting the tires yourself?

 

Nope, having my local tire shop do it.

 

A shorter-than-OE size for snow tires is, um, not great advice. Yes, the wheel is too wide for the optimal choice, but 245/40/18 is better for an X than 235/40/18.

 

I run stock tire size blizzak ws70 in xxr 9.75. I've never had any issues with the stretch or any problems running in the snow and ice.

 

There's only a three tenths of an inch difference in tire diameter between them. Hardly enough for the car to know or there be any issues.

 

225/40/18 really sucked for me last year.

 

[wrote snotty reply about four tenths in width and keeping the air in the tire when you run a 235 on a 9.5"-wide wheel in the cold, but - you know what? - I don't care]

 

how so?

 

Stock suspension, kept scraping the bottom of the front bumper on the road when coming out of driveways

Less ground clearance, less sidewall = firmer ride, increased acceleration, increased gas consumption, terrible on a road with potholes, I can keep going. I was on the stock 8.5" wheels.

I'm going to 225/45/18 on a 8 inch wheel this year. Oh what a difference 5% should make.
