I've starting doing some research regarding upgrading my rims and tires. I do want to go a little bigger on the tires than the Michelins that came stock, but I want to still carry a spare in the stock location. Anyone know what the max diameter is for the stock spare hanger?

 

now theres something I havent seen asked before. . . .

 

I'd have to look at mine again (I last looked back in Oct) but I don't recall there really being any extra room for a bigger tire, but I could be wrong.

 

I figure that I can at least go up to the 265/70s that I believe were optional, wasn't sure about anything beyond that. I'm not really fond of the spare in the bed method, but if I have to, I guess I can.

 

Yes 265/70/17 came stock on my 06 and I also think you could put a 265/60/17 under it and be OK its the bigger diameter that I'm not sure will fit under the truck.

 

Mine came with the 245/70s. 42k on them and they still have probably 50-60% tread left. But man, these things get no traction in the snow or off road.
So, i figure if I'm wanting sometime this year to get something for better traction I might as well go up a size or three

Figured fitting anything too much under the bed was a long short, but never hurts to ask.

 

I was able to fit a 305 65 R17 if that helps.

 

I have a 285 70R 17 for my spare. Still room to go up atleast one more size. Possibly two sizes.

 

That's one thing I never did and I hope I don't regret. I never put a newer / bigger spare tire under there. Right now I'm running the 17" 265's, and my spare is the old 16" 245. I guess it's kinda like having a doughnut spare.
