Stock Tires
Is it possible for me to use any of these tire sizes you mentioned:
255/65/17
235/75/17
265/70/17
275/70/17 with my current 235/70/17(stock I now believe) tires? Will they fit on my rim? Also my truck is a 4x2. When I plug my numbers in an online calculator on what I can put on my rim its either: P255/70R-17 or P255/65R17. The first size makes sense but this second one quoted is my "optimal" size but its height is shorter
The tire store recommended these:
Yokohama Geolandar A/T-S:

FS, so any change in the tire side warrants a recalibration? Im glad to see that its not expensive
That was me that did the sticker, and yes, it's a 4x4.
The stock size I had before the change, were 255 70 17's, so going to a 275 70 17 only put my speedometer out roughly 3%. I have a calculator here to figure it out, but I'm lazy, and to the best of my recollection, that was what I figured out before buying that size. I didn't get the PCM flashed for the correction, but I can live with driving at 100 km's knowing I'm actually doing 103 km/h.
That was why I went with a 275, because it was close enough without having to worry about recalibration, it really won't hurt my gearing, and they're a good bit beefier than the stockers.
I'm not sure if they'd work with a 4x2, but I suspect they would work fine. You'd be jumping from a 235 to a 275 with the same sidewall, so the diameter would be jumping up quite a bit. You'd need a recalibration, unless you already have a tuner.
As for all those tire sizes, play with this calclator. It's fun.

My first new replacement set of tires were Cooper ATR.
Coopers are very good tires. I'm sure there are some that dislike Coopers like other brands.
Anything would have been better than the Continentals that were on it when I bought my '04 F150.
1950-F-1
1996 Ranger
2004 F-150
You won't find many compliments from people that have those tires! I don't know why Ford puts P rated tires on a full sized pickup truck. LT tires should be standard IMO.
