Tire clearance issue
My 67 truck got a hand me down wheels and tires from my 2005 truck! the wheels are 16X8 and the tires are 285/75/16 on all corners on the stock height. I like the shape and the stance but the front tires on both side hit the corner (the red arrow in the pic) when turning. I was wodnering if this is an alignment issue (which my truck needs one) or the combination is just too big for the stock height. Is triming the corners somethig which people do in this case?
Thanks

Re: Tire clearance issue
Probably just a combination of tire size and wheel offset. I had the same issue when I first put wider wheels & tires on my K20 many years ago. These trucks being what they now are, I would not advise doing what I did. Grabbed my trusty hacksaw and notched the corners off that area of the fenders. Just an old work truck after all....

Re: Tire clearance issue
I have 285s on my 68 GMC and they clear without any issues. Looks like we have the same rims. I'm still running the drums, are you?

Re: Tire clearance issue
I have swapped to disc brake many years ago.
I am assuming I have too much caster?!

The tire being almost 33" tall is pushing it @ stock heights.

I don't know if you have, and there is no guarantee, but new front springs might cure it. 55 year old springs tend to sag a little.... I trimmed the fenders on my '70 Longhorn 4x4. It had new springs but it had 20" wheels & tires on it. I welded small pieces of metal over the opening that the cut created and you couldn't even see it.... LockDoc

Re: Tire clearance issue
if cutting the fender is not something you (I would not) want to do...install a coil spring spacer. A 1/2" spacer nets 1" IIRC (2 x the thickness of spacer)
That should raise the fender higher than the crown of the tire way it sits now |
