What size tire is allowable?

[Homer Ferreyra]

Does any one know what is the rule of thum for chosing tire size.



I know the comments about keeping the stock size intended, so just skip that comment. I have 265 75r16 and they seem to be rubbing. I bought the truck with these tires. I really like the way they look but it looks like I will have to lose them. The noise is driving me up the wall.

Is it true that you can go one size up or down?



Any suggestions?

It looks like the previous owner of your Trac put on some larger tires. The stock tire size either 255/70R16 or a smaller size (it escapes me at the moment). Some people have had no rubbing with the 267/75R16 tires if the tread is not aggressive. You've got three options I guess:

1. get a set of 255/70R16 tires

2. Trim the plastic in the rear wheel wells where the tires are rubbing

3. Do a torsion twist / spring shakle lift to get some extra clearance.



I'd suggest number 3, but that's just me.

You're already up a size. If you get the torison bars turned up an inch or so, they shouldn't rub on the front. Mine don't. Stock size, mostly, is 255/70-16 which is shorter than what's on it now.

I have 265/65-17 with almost no rubbing initially. The rubbing I had was on a protrusion of the inner fender that I fixed by heating it and flattening. Prior to the fix, it would rub only with almost full steering wheel turn and when hitting a bump, but not always - very minimal.



Edit:

I should have noted that the tires are on 17x8" with 3.5" backspace, which pushes the centerline out .5" (without a spacer). 3.75" backspace would have worked too.

Thanks everyone good responses and information. I found out that I can use spacers that will push it out the tire a bit stopping the rubbing and increasing the turning range. I think however, that I may just give in and scale down back to the stock size tires.
