235 tire width ... go with 40 or 45 high ??
In other words, when choosing between these two, which is correct for a 7.5" rim on a SRT-4 ?
235/40R17 or 235/45R17 ? One is 1/2" taller than what I am now using, and one is 1/2" shorter.
Thank you

I'd try to get the one closest to the stock size to keep the speedometer correct....
My $0.02

Thank you everyone. I'm going with the 45, as it throws the speedo off by almost 2mph less than the 40 will, and offset isn't an issue.

How exactly is a 40 series tire wider than a 45 series tire? Just curious!

It was kinda vague...
I prefer the lower profile cause it makes the tire look wider. It's like comparing a 235/40/20 on 20x8 rim to a 235/40/17 on a 17x8 rim. It's the same width, but with the lower height it "looks" wider...
...just me though...

this is an easy one. the 235/40 can not be safely used on a 7.5" wide wheel.
