I want to get as much contact patch with some 225/45/16's.

Does anyone know of any wheels that at 16x7.5 instead of the common 16x7?

Are there ary wheels out there that are close enough in offset that might be able to be custom drilled for 4x108?

Well, rim width won't really help with contact patch. That is all about what tire you choose to run. I run 205/50/16's on 16x7 Enkei RS-6's and they seem to have a very nice contact patch. I've looked into wider tires, but the thing to keep in mind is the overall diameter of the wheel/tire when going wider. It's tough to find something wider with the proper aspect ratio to keep the overall diameter the same as to not mess up your speedometer and throw off you final drive gear ratio. I'm very happy with the 205/50/16's I have, so I'm not so worried about going wider until I go to possibly a 17 inch rim in the future, but also, living where I live, I like to have a decent amount of sidewall to help the suspension due to nasty country roads here.

Yes, and wider wheels allow you to run wider tires. For instance, a 6.5" wheel with a 205/50 and a 7.5 inch wheel with a 225/45 have approximately the same sidewall and overall diameter, but one has a much nicer contact patch.

That said, 7.5 is a weird size. You could certainly have some custom-made, if you were really serious, but I imagine you'd have to go up to a 16x8 to get any mass-produced wheels. Rubbing would be a serious issue.

A 7 inch wide rim should be plenty to run like a 225/45/16. The overall diameter is only 1/10 of a inch different than a 205/50/16. I don't know what kind of rubbing issues you'd have with a 225/45 as compared to a 205/50. It is a substantial bit wider.

*EDIT* According to a rim width guide on the Kumho tires website, you can run a 225 on rims from 7 to 8.5 inches in width. Don't know if that is of any help, but there it is.

I run a 7x16 wheel 45mm offset and 205/50 tires just like the other guys and it works and looks great. I don't think you will gain anything from what you are talking about.

Absolutely it will.. to a point.

I know for sure that I gained somewhere around 1" of tire when I went from a 6" wheel to a 7" with my 225/45-16s.

My friend has 16x8" wheels on his M3 with the exact same make and model of tire that I have, and they are measurably wider than even my 7" wheel.

I'd love a 16x7.5" wheel, I'd most certainly gain contact patch.

Yeah, like what Omni said.

I think I have heard that for every 1/2 inch of wheel width you gain 2 tenths of section width. Thats excellent. You need everything you can get when you are trying to competitively autocross a Focus.

go up to a 16x8
And leave STS...7.5" is the allowable limit. Anyone make some 15x 7.5"'s...thats what I'd like to see (with a good offset, 42-45, of course).

Thanks for bringing up this is for my STS car.

And what tires would you run?? I am not willing to try the BFG KD's, I heard they are not very good in the wet, which is what it's like much of the time up here in WA.

Not even the Azenis RT-215 205/50/15 on a 15x7.5 would be as wide as the Hankook 225/45/16's on 16x7.5.

I am thinking I will just look for some light 16x7's such as the Rota Slipstreams or Grids and throw the Hankooks on and shave them to 4/32's and install them for race events only. Sell the 17's with bald Kumho's on them and put tires on my stock 16's for daily drivers.

I would debate that. The 205/50-15 RS215's on my 6.5" wheels are wider than the 215/45-16 'Kooks on my 6.5" wheels (yes, I have both). I would guesstimate that width-for-width, on the same width wheel, the 205 Falken would be about the same as the 225 'Kook.

Erik-

SSR makes a 15x7.5, that's what all the Cibics run up front...
Indeed, but I dont seem to recall the fittment being offered in our 108mm bolt circle, and I also recall an offset of 40 (not ideal, 43-45 would make me happier)...which is less of a concern than actually getting something that bolts up.
Maybe Roger can chime in and talk a little about custom drilling and the like on the SSR's

Isn't that crazy how wide the 205 rs215's are?! Isnt the 215/45/16 rs215 wider than the 205/50/15 rs215? I've seen those laid down next to eachother. I bet the 215 azenis are about on par with the 225 kooks.
