two set of rims+tires for the same car

my winter are on 17X7.5J rim, 225/45/17 tires

my summer are on 17X6.5J rim, 225/65/17 tires

Each spring I just put rim on and off myself, is there any problem? Do I need to adjust alignment each year?

obviously the car's elevation is lower when I am on winter rims. Is there any hazard with my current configuration? Your comment is highly appreciated.

No you do not need an alignment every year unless you notice the car is not driving straight or some other issue. However every year or two is not a bad idea because your alignment can be off by just hitting a good pothole or two.

As for your tires you generally want the thicker/taller tires for the winter so you have more rubber to absorb the impact of a pothole since roads are usually worse during the winter. But its not going to cause any issues the way you have it. Also having the car taller in the winter is another benefit to avoid hitting chunks of ice and plowing snow after a big snow storm.

Have the correct size tires at all times. It makes no sense that you have low-profile tires in the winter, and a larger profile in the summer.

^ Above replies are correct. Why do you have lower profile in the winter and higher profile in the summer? It should be the other way around usually. Your summers should be 225/45/17 and winters should be 225/65/17. If anything, you could have both sets running 225/45/17 and you would be fine. I'm running 225/45/18 in the winter and 245/40/19 in the summer.

For myself, I usually get an alignment every spring once winter season is over to make sure the numbers are dialed in correctly.

No, that doesn't make sense either. Like I said, you should have the correct size tire at all times.

OP didn't give us any details, so we don't know if that's the 225/45 or the 225/65 or something else entirely. Without details, my general advice is the best I can offer.

It’d only make sense to run higher profile in the winter and a lower profile in the summer, unless OP doesn’t care. As mentioned above, you have more rubber for winter driving because the roads are not the best in winter. Either way, on a 17 x 7.5 rim, 225/45/17 is one of the many correct tire sizes you can run. On the 17 x 6.5 rim, it seems 225 isn’t recommended according to https://www.tyresizecalculator.com/char ... size-chart, 215 is the max you can wrap on a 6.5, but 225 would still fit. For a 6.5 rim I’d go with 205 or 215.

Yes, you can have more profile, but you need to reduce the wheel size. This keeps the outer diameter the same, and that's what's important. That's what I mean by "the correct size at all times". Right now, OP has 2 sets of tires with vastly different outer diameters.

Derass is correct.

225-65-17 has a greater overall diameter than 225-45-17, it makes no sense to be running different overall diameters

What is the stock tire size OP? read the manual or check inside the driver door jamb

This setup is absolutely not recommended by any shop if the winter tires are actually 225/45R17 when the summer tires are 225/65R17, with the profile being the only difference. The 45 profile is a 12.4% reduction in diameter, WAY out of the maximum 3% recommendations when swapping different sizes. This will seriously affect handling and speedometer readings.

OP are you sure of the 225/45 size? What is your year/model?
