225/45/18 on 235/45/18 car?

[kalpeshp]

My 2014, 18 inch option fusion's sticker tells me to use 235/45/18. Can I use 225/45/18 instead?

Hi kalpeshpand welcome to the Ford Fusion Forum. Yes...you can. However, out of curiosity, why do you want to go to a narrower tread width? Cost?

 

A few things to keep in mind:

- The smaller overall diameter will throw off the speedometer/odometer by approximately ~1.1% (which is actually rather negligible).

- Apples to apples with the same tire brand/model, it will also ride slightly harsher (~4.8% less sidewall).

- The smaller overall diameter means the tire will also look smaller in the wheelwell (if you care about looks).

- Be sure to purchase a tire which meets the load rating and other tire specifications required for your Fusion by Ford.

 

You can compare the tire size differentials here: https://tiresize.com/calculator/

 

Let us know how you make out and good luck.

Thank you @bbf2530 for the response! Yeah, The main reason is cost. The new 235/45/18 tires are costing me around CAD 1250, But I found someone who is selling hardly used 225/45/18 tire for CAD 800. Tires are good in good shape. So before making the decision wanted to understand if it's safe or not. 
Some more information:
Its Winter tires, Continental VikingContact 7.
Load and speed rating is 95T where as my fusion's recommended load and speed rating is 94V.

With this full info, Do you think it would be safe to use that tires?

Hi kalpeshp. They are a good snow/winter-only tire. Are you looking for snow/winter only tires? If yes, and they are not approaching being too old (>~5 years old), they could be a good deal.

Also, while they obviously can be driven year-round, the ride and handling in warmer weather will be of a lower quality than your factory all-season tires. 

 

My opinion: Due to the smaller size and lower speed rating (T rated is up to 118 mph) and winter only construction, I would not use them if it was for my car. 

 

However, if they fit your needs and preferences, then it may be a good fit for you.

 

Keep us updated and good luck.

Hi Kalpeshp, 

 

What does your sticker tell you to run your for air pressure in the 18" tires?

Sorry, for the delayed response. I tried replying for couple of days. But website was down for maintenance.
The sticker says 34 PSI. Would tire pressure change for new size?

Thank you for the reply. I was only looking for winter tires, I was not getting enough confidence to go ahead for the purchase. So, decided to buy new one. Thanks for taking time to reply.
