Seen 4 nice used tires online and am wondering if I can use them on my x type sport?
205 50 17
I think its supposed to have 45's...will 50's rub?

 

iownme, the size difference between the two is fairly insignificant. You should be fine with that size tire. Just keep in mind that your speedo will be off by 3.3%. So, when it is indicating 60MPH, you will actually be travelling 62 mph. Just something to keep in mind.

I am running 225/45R16's on my car right now. No issues with those.

 

They will rub.
I am assuming your Sport currently has 225/45/17 tires. The rolling radius is 199.27 cm.

The 205/50/17 that you are considering has a rolling radius of 206.50 cm. That is a difference of 7.23 cm or about 2.75 inches.

They are also narrower and will handle quite differently.

 

Thanks gents. I left the town where the tires were being sold, so that bargain will have to be snapped up by someone else..lol

 

Just a thought..why put any used tires on a car? If they were that great, why would they be on the market?????

 

Who knows what the persons reason for selling was...I have no problem with slightly used tires for a fraction of the retail price...same with the purchase of my used car and my used audiophile quality stereo...lol....for me, used is a good way to go
