tire size fit inquiry
The OEM tire size for our Kia Optima is 205/60R15 and I'm wanting to acquire a set of winter treads for it. I came across what seems to be a decent asking price from a guy who has a barely used set of size 205/55R15. I'm unclear on whether that size should be fine, or not a good idea (and if not why not) to deviate in that regard from OEM recommendation. Any advice/comments appreciated. Thanks.

Here is a chart to check

The only difference is sidewall height. this may make speedo off. Be sure tires on same axle are the same size. Different sizes can cause problems. Here is a caluator

If there's a big difference in tire height, it can throw off the antilock brakes and stability control I believe? That could be if you just have one tire different, not sure.
One thing before buying used tires. Do some searching for how to read the DOT number to determine how old they are. DO NOT TRUST the seller, unless he's a good friend or neighbor.
Drove 30 miles one time to pick up some "barely used" tires that were supposedly taken off a new truck 1-2 yrs prior and stored in a garage. Looked in very good condition, even still had some of the nibs on them. Paid $100 plus another $40 or so for mounting and balancing. Second day driving thought I had a flat but couldn't find anything wrong. Went to a shop and they said "tread separation". Called the manufacturer hoping for warranty....turned out they were almost 8 yrs old!
Lesson learned...

A lot of retailers won't mount incorrect size tires due to legal liability.
Be sure the load & speed rating is the same for the different tires.

Thanks for all the advice/comments. Actually it turns out the seller was (is) selling 16" tires, not 15. So no way on the whole idea anyway.
