when in all actuality the perfect 17 inch tire is 215/40/17? im have lots of problems finding rims and tires i keep reading tech but just having so many probs im scared to go with a 205/40 tach is way off and the 215 is only .1% off that is the perfect tire im not understanding

 

I am running 215/40/17. I am not sure why they try and push the other size.

Moved to tread & butter

 

I think you can get the service department to recalbriate your wheels after it's put on.

 

Most shops stock 205/40-17 and 205/45-17 because that's the size for Honduhs.

 

I wanted to get 205-45's for my box but there are more tire choices in 215-40-17. The 205-45 gives you a little more sidewall and the narrower width MIGHT help a little on rolling resistance and gas milage. Go with the 215-40's!!!

 

215/40/17 here

most tire shops don't think they will fit on our car.

 

Yeah, 215/40-17s are great for the crappy roads we have up here in the Bay Area. I love those Neo Gens!

 

215/45/17 Because I wanted more rubber between the
Chicago Pot Holes and the road. I ordered online and have
no issues.

 

I agree w/ loneyl raven, I'm riding on 215/45/17's for the same reason...

 

215.40.17 on my xA.

Biggest difference between the correct size and one size up or down is price. It's an odd size, so it costs a lot more. Maybe that's why they think you want something different.
