Re 17"/18" descrepancy, see above reply. If I can get it to 270 or 275, that'd be ideal. I'll measure it. Thanks...

 

Just get another set of 265/70/17s then. They’re one of the most popular tire sizes and there will be a lot of tire choices.

 

2wd or 4wd ?

 

Sorry, I thought I posted that. It's 4WD. I'm still looking for clarity on the 270/275 footprint option. Thx!

 

You will likely not even visually notice a difference with those. A 285/65/17 would give you the same diameter that you have now and would be almost an inch wider.

Not sure what your goal is here. Let us know and we can help you.

Please keep in mind, with popular tire sizes you have many brands and styles to choose from. Less popular in between sizes will have a lot less to choose from.

 

Thanks, 2008_XL. Again, the Hankook Dynapros (that I thought were original issue, they might be as the spare is the same tire) are old enough that I'm beginning to see small cracks between the treads. The Window sticker says the originals were 235's, but I can't know if they were swapped/upgraded by the original dealership or a subsequent owner. I'm trying to find the sweet spot in terms of traction without paying any more of a MPG penalty than necessary. I'm looking at 285/70R/17's now. Walmart says they won't fit, but many online sources say a stock '07 XLT Extended Cab 6' bed/4x4 will accommodate them, no problem.

I found a set of TravelStar Ecopaths 285/70R/17's that look pretty tempting as I'll have to buy five in order to replace the spare. The reviews look pretty good but I've never owned a set.

 

If traction and MPG are of concern, a wider tire is going to give you the opposite of what you’re after.

A skinnier tire will usually have better traction, and the taller and wider you get, the lower your MPG’s will be.

The door placard on the drivers door jamb will tell you exactly what tires the truck uses. I’d suggest going with the OE size for what you’re after.

 

@RickTM Have you looked at Michelins? I hear those are aight.

 

I agree with regard to the effect on fuel efficiency, but not on traction. Michelin has priced itself out of consideration. I think I have what I need now in terms of advice. Thanks, gents.

 

Not on traction? You put more weight on a narrower tire and get better traction. It’s simple.

It’s not my opinion, it’s a fact.

Hope you find what you need.
