How to know what size tires will fit?

[bobcat_fisherman]

How do you tell what size tires will fit on your truck without test fitting them? I currently run 305/70/17 Nitto Terra Grapplers but want to get GoodYear Duratracs. They don't make that exact size. The tire shop by me can order them but don't have them in stock. How do I know which tires to order that will fit my truck?

 

Pic with Nittos. I don't think I want to go wider but I don't want to be too skinny either.

What sizes do they have?

With a 285 or 295 in similar height you should be fine

315/70R17 will be a little taller and wider. But it is the closest youre going to get unless you go to something like a 285/70R17

 

Those 2 are your options with the Duratrac with a 17"

Would 285's be a lot smaller that my tires?

About an inch in height and .75 inch in width

Get 33's

Get 33's

They don't make the duratracs in a 33 for a 17in wheel.

The 285 is basically a 33. It measures 32.71x11.22 the 315 is 34.36x12.40

If that size isn't what you want, there are lots of other options for tires. That aren't Goodyears.

I have 305/70/17 nitto terra grapplers right now. They're boring as hell but I want a different tire. I do a lot of driving so not a mud terrain. They don't seem to make much in a 305. I'll probably just go down to a 285. I was just worried I'd lose a little height of my truck going to a smaller tire. I'll lose about an inch in overall truck height, right?

Playing around with a metric tire calculator it looks like if I go to a 285/70 its a smaller tire but if i go with a 285/75 its the same height as mine now but a little narrower.

What about the Nitto TRAIL Grappler 295/70-17. Should be just a bit smaller but with a more aggressive look.
