First thing you need for tire sizing is the size of the original wheel. Then you size the new tires to match the diameter of the old wheels.
And, you need to know how wide your new wheels are 18 x ?"

For instance, 05 MC SS came with 235/55R17 on a 17x7" rim, diameter 27.2"
If I wanted to upsize, I'd go 255/45ZR18 on a 18X8" rim, diameter 27"

p.s. 225/40 18 is 25.1" and needs an 18x8 inch rim.
Is that comparable to what your car came with?

hi Tom. I joined the forum a couple of months ago and enjoy reading all the mod's being done. I have a 2004 Intimidator and want to put wider tires on the stock rims. I read your info above and was wondering if 255/50/17 nitto 555's would fit without rubbing anywhere. says they will fit 7" - 9" rims with a 27.09 diameter so the spec's are ok I think. not sure about the rubbing. any info will be appreciated. Thanks Tom
