Anybody running 45 series tires, versus 40's?

I ran across a great deal on some 205/45R17 tires. I'm thinking these might give a slightly less harsh ride, less rim-dent worries, about a centimeter more ground clearance, and a slightly taller effective 6th gear. Downsides are slightly dulled steering, higher center of gravity, speedo cal issues, etc. Tire diameter increases by 3%.

Not sure if they might rub? Anybody already try this?

Been running 205/45/17 continental DWS tires since the beginning on my 15 fiesta. no issues.

I think if you drop the car you could run into some clearance issues but at stock height you should be fine.

Perfect timing on this tonight driving home I told the wife I love this car but the ride sucks on these ruff streets and roads I am on. I won't track this car so don't need such an aggressive tire setup. I will switch out to that size tire myself once these need replaced. Hoping the 45 series works well (car is not lowered) and smooths out the ride some. I also have a Edge ST it has 21 inch rims with low profile tires and it has the same ride over ruff roads.

I have 205/45ZR17 on stock suspension and definitely a lot more comfortable.

If you go both wider and taller (215/45R17) you get rubbing at full compression with stock suspension.

I have them but my wheels are 17x8 so it's a little bit stretched out. 0 rubbing on stock suspension which quite frankly is already lowered due to them rear spring perches disintegrating and overall use.

That speedo issue was solved with my tuner, Cobb has a section for tire height that corrects the wheel speed.

I have one profile higher on my winter setup because I already had the tires. rubs like crazy on big compressions. I am lowered on whiteline springs.

personally I would not buy tires one profile up just to save a little. I can wait to burn mine off so I can go back to correct profile
