I'm thinking if going 18x11.5 rear rims and 17x9.5 front rims. The 335/30/18 in the rear will have a small side wall......

Looking for the lowest profile 275 so it will match the profile of the 335/30/18 as close as possible......

Any suggestions you guys have. I tried searching tirerack but can't find the right numbers for width/profile/diameter to match.

???

With a 17 go with the 275/40/17, it'll only have .19" more side wall height.
Why not just go with a 18 x 9.5, and run a 275/35/18 ...?

You know what, I guess the only important part is the rear tire and traction. Wo cares what's up front, right...?
I mean, going to an 18" up front won't change the wet traction ability at all, right?

I've been running 275/35/18s for over 10yrs, and I seriously doubt you'll have any less traction than a 275/40/17 in a identical brand/model. Plus with a 275/35/18 you'll have a large selection of brand/models to chose from.

you will also be able to upgrade your front brakes with the CTS-V or Z06 brakes later if you wanted too. i think you would be much happier with 18's on all 4 corners. i am upgrading to 18's from my 17's just for the bigger brake and larger rear tire options.

Yup......you're right too. Or the big Wilwoods or MovIts I've been wanting.....

Do you happen to know which thickness spacers I would need for OE Wheels 18x10.5's.........widened to 11.5"
Brand...?

I know I'll have to do some serious hammering on the inner wheel wells. But will my normal LCAs be cleared by the inner tire wall? I really don't want to do a mini-tub.
