So I picked up a great looking set of C5 wheels for pretty cheap this weekend. Now I am trying to put tires on them so I can slap them on the car. The rims are 17x8.5 fronts & 18x9.5 rears. My questions is, should I go with the stock size wheels (245/45/17 & 275/40/18) or should I go a little more extreme. I was thinking of going with the stock sized fronts & 285/35/18's on the rear...any opinions on how that would look once on the car? Is there a better size for the front that might match-up with the 285/35 rears? I have read & re-read the FAQ's but still cannot make up my mind. Any help would be appreciated!! BTW, my car is a cruiser. No racing, no canyon-carving or hard driving.

Here is a picture of my wheels....


The wheels look a lot better than they do in that picture, btw.

 

You need to match the outside diameter of the tires that came on your car from the factory, as closely as possible. I think the Y87 package came with 16x8.0" wheels and 235/55-16 tires (26.1" diameter).

So you should consider 255/45-17 for the front, and 285/35-18 in the back (26.0" of 26.1" depending on manufacturer). The 275/40-18 is 26.7" and that's going to throw the speedo off, and be a lot larger diameter than the front tires.

 

Thanks a ton bro!! Any advice on how to talk the angry wife into letting me actually buy them? Last time I brought it up, it looked like this....

 

Just placed my order with Tirerack for the 255/45/17's & 285/35/18's. Thanks!! I cannot wait to get them on the car!!

 

Awwwwwww I'm telliiiiiing!!!

Should look sweet once its rolling!!

Which tires did you go with?

 

I went with the Sumitomo's. I know they aren't the best, but why buy a super expensive pair of running shoes when all you will be doing is walking fast?
