Default can someone double check my winter tire/rim purchase?

about to order a set of winter tires and rims for my IS350.

Tirerack has b-grade rim packages with brand new tires. $999 for the whole set. couldnt ignore that price.

The wheels are TSW Kyalami 18x8et40 5x114.3 hyper blk

Tires are hankook w300 winter (225/40R18)

will i have any fitment issues around the brakes with this setup?

thanks in advance,

-Andrew

Unless they have a very large lip, that should work just fine.

I would consider going with something a little larger in diameter such as 225/45's or 245/40's in the rear to keep the front to rear stagger.

not arguing, but why would you want to keep the stagger? for looks?

i want to keep the tires as narrow as possible...especially in the rear for better snow traction.

sounds like a good deal. tire rack should be on top of this for your car and if it will fit. i got mine from another member who purchased from tire rack also. they are also 18" and they are not staggered. i am going to have to put them on in about 2 weeks here and looking forward to see how well they handle. i went thru the last winter on the performance tires so this will be a first for me. i have never had winter tires on any of my cars...good luck!

I agree. No need to stagger your wheels. The tirerack set-up should work with no problems.

Yup, narrow snow tires = better traction.

The stock rear tires are about 1" larger in overall diameter than the fronts. It stands to reason that the Lexus engineers developed the traction/stability controls and perhaps the ABS with these specifications in mind.

If you run a non-staggered setup, you might invoke these systems prematurely or even retard their intervention as the computers expect each axle to spin at different rpms.

With that said, most cars probably have a little margin of error built into them to compensate for uneven tire wear between the axles. Many rear wheel drive cars wear out their rears quicker than the fronts. So, going with a non-staggered setup may be within the computers parameters. However, you're going to be closer to those parameters, which may not be the smartest thing to do especially when traction is critical.

Hope I've made sense.

Keeping the stagger and having skinny tires is not mutually exclusive. As I mentioned above, 225/40 in front and 225/45 in the rear will keep the stagger and still keep the tires skinny. Besides, we're driving ~3600 lb cars, not light weight subcompacts. 225's are fine but going slightly wider probably wouldn't hurt either.
