Why dont you put you stocks back on
and then you can tell if it is rims or your car
This would be a simple way to help determine the problem without spending money

Actual size/wide/diameter varies by make and model.

Agree with mold release and alignment, but also keep in mind how worn your previous tires were. If they were close to bald then they had a much better contact patch (less tread), making new tires feel (and be) less grippy.

His 255 should be at least as wide as the stock 225 S02.. A typical 245 is as wide as the 225 S02, so unless its the thinnest 255 ever made, he should be ok.
Keep in mind, the first three digit's on the tire's sidewall is a measurement of sidewall to sidewall. The actual tread width can vary as in the case of the S-02 having an 8.5" tread width.
The 255 tire has a 10.039" measurement from sidewall to sidewall. If you times the tire width by the aspect ratio, you get the sidwall height. Times 10.039 by .35, and you get a sidewall height of 3.513.
Do the same thing with the S-02, 8.858 x .50 equals 4.429" sidewall height. Times the sidewall height by 2, add the rim diameter, and you get overall tire/wheel diameter. That would equal 24.858".
The same formula applied to the 255/35/18 comes out to an overall tire/wheel diameter of 25.026". This tire spins less revs per mile than the original OEM Bridgestone Potenza S-02 rear tires.
I guess you didn't read the previous post that talked about revs per mile

As your tires get to be bald (or near bald), the tire compound gets much harder (to help hold the tread against the patching) which SEVERLY decresses grip.

What brand and what model tire did you get those figures from OR are those just the theoretical norms?

i bought rota d2s 18x8 and 18x9. I wrapped them in 215/40 front and 255/35 rear, bfgoodrich gforce kdw 2 tires
The specs from the 225/50/16, and 205/55/16 are Bridgstone Potenza S-02
Tread width can vary from tire to tire, even within the same manufacturer. The S-02, with a tread width of 8.5" wide at the rear, is considered wide for a 225 width tire. The actual sidewall width of this tire is 8.858" from sidewall to sidewall, although on tirerack.com, it says 9.2"
The basic formula is divide the first three digits by 25.4, and yet get the measurment in inches. Thats how ya get 8.858".
I dun't know how tirerack get's 9.2
