Tire/Rim size important?

Stock tires on my '04 2500hd are Lt245/75 R16 on a 6-5/8" wide rim.

I would like to put Goodrich All Terain T/A 265/75 R16 tires on these rims but the 265 tire specs call for a rim 7" - 8" wide.

the difference in tire diameter between these tires is 1.2".

I'd like to install the larger tires but wonder if there would be a serious or significant safety/performance problem because of mounting them on the smaller rims? I suspect I should just go with a stock size tire but I have seen this very combination (265 on a stock rim) on the road and it looks pretty good.

I would never go narower than the recomended rim width! The 'wander' experienced could get pretty bad and dangerous! I suggest going no narower than a 7inch rim(inside of bead lip to inside of bead lip is where it is measured) with an 8inch being allot better.

My personal preferance is to run a rim no narrower than the tread width. I have gotten the best tread wear, handling, and traction doing so.

What truck came with 10inch wide wheels from the factory??? I have seen

9.75 wheels on 70's camper specials.

Also, you would tear a 215 up if you mounted it on a 10inch wide wheel! Barely over 8inch sidewals on a 7inch wheel and under 7 inch tread width... THAT is begging for a blow out!!!

I can tell you with absolute certainty that:

A 1970 Chevelle SS 454- LS6 and LS7 came with ten inch wide rear rims.

From the factory? Chevelle Rallys is what it had and if memory serves, they were 7inch...maybe 8. Factory 10inch though, never heard of it in all my years!

I have never come across a FACTORY LS7 Chevelle anywhere! in person, on the net, any of my GM Gurus, or in any publications. I have heard that an LS7 could be purchased from a dealer and installed in '70, but as a factory option...?

If you can prove either of these, I would appriciate it!

I personally rode in 2:

Returning Viet Nam Vets, ordered them as they were "Shorting" I think the LS7's were COPO cars, but the LS6's had the 10" rear wheels, I worked on these cars when they were new.

So in other words you cant prove they were factory, but maybe dealer installed?

I'd have to travel back in time:

But they were the 70 Chevelle wheels, Spoked steel.

Maybe they were widened by a vendor?

I have been doing some more digging to try to prove you right and me wrong...nothing either way yet. This might wind up being unresolved. Oh well...

There were and still are a lot of wheel wideners:

The 70 LS6's and only 2-1970 LS7's I worked on, had 10' rims.

We put N-60-15's on them in 1974.
