Question Running a 205 tire instead of 215. Good or bad idea?

Hey I ordered a set of speedy lite 5 wheels 17x7 with 45 offset. My question is I am going to put some summer tires, havent chose which yet, and I would like some help on selecting a size.

I had 17x7 42 offset wheel, and it rubs when I have a full load in the back and hit a bump. It didnt rub really when I first got them, but I'm thinking the shocks maybe bend a bit more than before so I get more rubbing these days. I'm hoping the 45 offset wheel do not rub but I thought If I put a 205/50 17 tire on instead it wouldn't rub for sure.

Are there disadvantages to 205 tire, or the difference minuscule? I've heard running slightly more narrow tire could make cornering better because sidewall would be more stiff and trade off a little of comfort.

Thanks for your input

Without knowing what tire you want to run, the thinner tire will have less contract area, so you will lose handling. Better snow performance though ;-)

Check to see if it even has the same load rating. Going to a larger tire rarely has any negative side effects but undersizing tires can be bloody dangerous in many cases.

I would stick with the 215/50.

I'm running 225/45/17 on my rims. I'm also at 17x7 but my offset is 50. No rubbing so far. I would go at least 215 and you can always do a fender roll, but I'm almost sure you won't need a fender roll unless you're lowering your car. By the way 215/50/17 are stock on the 6 with 17" rims.

thinner tire means more curb rash
