Luke or whoever else that can help.... I wanna go with the 265s in the rear, but keep the 235 in the front. What I wann know is do I have to change to from 45s to 40s or what?? Right now I have 235/45/17s all around. I was gonna go 265/45/17... but what's the correct way.

the 235/45-17 has an overall diameter of 25.3" so, you would need a 265/40-17 which has an overall diameter of 25.4" and remember the 265 needs a minimum of a 9.0" wide wheel

here's a quick link to a tire search

hmmm....

Well, I thought about the rim size too and remembered I only have 17x8... I was trying to wait for info, but then I noticed a nail in my other tire and upon gettin that out I saw the tire was really damaged and needed to be replaced ASAP. So I went on and bought two new tires for the back, but I went with the 255/40/17s. Is that okay?? I do plan to get 17x10 on the back soon and then I'll go with the 265s or whatever. I hope I didn't do something stupid and put myself in danger on the road. Thanks for any info.

the 255/40-17 is recommended for a minumu wheel width of 8.5" so you will most likely see excessive wear in the middle section of the tire unless you run a very low preassure which will inturn lower the load capacity of the tire and could cause failure
