I recently bought 2014 Impala LT with P235/50R18 wheels.
I suspect that it still has original OEM tires.
I strongly dislike its performance on a fresh slushy snow and want to buy some winter tires.

I am not excited about an idea of winter tires in P235/50R18 size and want to get smaller steel rims.

Do you have any experience with winter tires on smaller rims e.g. P225/60R17 or P225/65R16?
Would P225/65R16 even fit 2014 Impala LT?

According to my calculations both sizes should be OK.
wheel-size.com/calc/ agrees with me:

If you have the original Firestone Firehawks? I would switch to a better all season tire. I had the Firstones and hated the winter traction. I can recommend General tire altimax rt43. I just saw my old Impala at local dealer with 52K on them and they still looked like they had a lot of tread left.

I put 17" steel wheels with snow tires on my 2015. Stock wheels were 19". The 17" clear the brakes. Close fit but they do clear. Have run them for 3 years now, no problems.

Thank you very much greed!
Visually I saw a lot of space around brakes but wanted to get a confirmation from people who already did it.

Could you please share width of your winter tires? Are they P225/60R17 or else?

My personal all season preference is Goodyear Triple Thread Assurance. However this time I would like to experiment with winter tires.

Has anybody put P225/65R16 or similar on Impala?

Yes, I used 225/60/17 tires. For wheels, I used Unique Series 83 Black #83-7713 . They are made by Cragar. They are 7" wide, 5.5" backspacing, +38mm offset. I got mine from Summit Racing. The Summit part # is CRR-83-7713. The Summit part description says they are not TPMS compatible, but I have TPMS sensors in mine, no problem. For 3 or 4 month running time I did not htink the sensors were worth the expense but wife wanted them, so what do you do.

here is what you need to do (i am assuming you have a 5x120 spacing with a 66.9/67 mm center bore).

1) purchase 4, 2013-14 malibu ltz 17x8 r1u option rims off ebay. mine were from a salvage yard and were in perfect shape and had the tpms included.


2) purchase 4, 235/60R-17 Bridgestone Blizzak WS90 snow tires. they are just a little bit larger in total than my all season tires on my stock 19in rims. they are incredible tires.

this is MUCH better than trying to find an aftermarket rim that MIGHT fit. this system fits perfectly and is a stock GM setup. it is a close fit around the calipers and front strut but it works. i wish i had found a post like this when i first started looking !! would have saved a ton of time!! :)

your welcome.

Winter Tires on smaller rims?

I have a 2014 LTZ 19" wheels useless all season tires in snow!
I bought 17" wheels from Summit Racing $60. Goodyear Wintercomand 215/65/R17 28" O.D. and Amazon sensors all total it was cheaper than snow tires for the 19" wheel $225. each.
They fit and work GREAT!
You do need lug nuts to match the wheels 14mmx1.5 I think... Stock lug nuts for alloy wheels will not work!

Hello to everyone...
My first post... MORE TO COME!

Locations help a lot with us gauging just how much snow.

"all season" is a very rough term, use TireRack and you can compare tires some all seasons are great in snow some suck.

Here near Green Bay I put all seasons rated well in snow on my wife's car Last she had some General forget which exact model, was good with them the first winter but unhappy the second. Now she has Goodyear Weatheready and is happy so far this winter.

People fixate too much on rim diameter 18-19" on these cars is enough sidewall, 20 and the sidewall is getting too short and will affect performance. If coming down a rim size clears everything and opens up tire options great, but these days 17-19" there are a lot of choices, not like a few years ago.

Another thing to consider is if going dedicated snows and swapping to all season/summer tires you spread mileage over two set of tires. This can lead to one of both sets of tires "aging out" before they wear out. Are you willing to throw away a set of tires in 3 years or so even if they have tread left?

Most tires have a shelf life of 7 Years not 3 Years.

Here we have about as much snow as in Green Bay I assume.
However my primary concern is not about having a lot of snow on a road.
I want to have a better traction when there is just a bit of slush/snow on a pavement.

Here people already shared their experience moving two sizes down from 19" to 17".
In my case I want to move two sizes down from 18" to 16".
So far nobody shared such experience.

I suspect that my LT with 18" rims may have smaller rotors than LTZ with 19" rims.
As a result 16" wheels may be compatible with my LT.

I'm in Appleton, I have used dedicated winter tires since 1995 on 3 different cars and the last set on my P-71 Crown Vic lasted 6yrs. and sold with the car.
Never ever had tires "age out" if anything the summer tires last longer!

Maybe it was just the cheap Cooper's I had for snows then. By 4 years old fresh all seasons were better than the snows and o stopped using them.

I had 16" wheels on my 2010 Impala. 16" will not fit on the newer models. If you have a Limited they may (old body style) but I don't know if they changed anything on the Limited.

Last year I bought Goodyear WinterCommand tires with 17" steel rims from a GM dealer and I love them.
So far I do not have TPMS sensors installed and just manually check tire pressure from time to time.

What should be set pressure in 17" winter tires?
Should it be the same 35psi as in OEM 18" tires or something else?

Just go with whatever is on the side of your tire. I usually run 5-7lbs under the max pressure for better traction in the snow.

I live in a major city. So traction in a deep snow is not a primary concern. Also I noticed that Impala is not as steady on 17" rims at 120-130 km/hr (yes, we have a toll highway where I could drive at this speed during rush hour; at the same time I do not work there anymore and do not need to use this tollway anymore, so high speed performance is not my primary concern right now).
So my intuition is telling me to add 2-3 psi when I need to drive 120-130 km/hr or use the same 35 psi or a bit less when driving around a city.

Even so, just run them at whatever the pressure says on the side of the tire, or a few lbs below. Generally thats the best route to take. Not sure what advantage you'd have running them at 35psi just because your tires on the 18" rim were rated for that. They put it on the side of the tire for a reason lol.

The PSI Rating on the side of the tire is the max operating pressure for the tire, the proper pressure should be taken from the sticker in drivers door opening not the tire itself. The tire pressures on the sticker are what GM has determined is correct based on the weight of the vehicle and other design factors specific to the vehicle.

One thing to take into account is that the pressure will rise as the tire gets warmed up. I have my tire pressure set at 33 psi per the sticker. It will be at 35 psi after 30 minutes on the highway, and a bit more in warmer weather.

From my understanding the pressure indicated on the door applies to the original equipment that comes with the car no?
