Rim/ Tire Question
 

Hi

I know,it is a stupid question,but about Tires and Rims I really have no clue.

I bought the Car with 2 sets of wheels.

one set (which is mounted on the car) Workhorse LT245/75 R16 Tires

the Set with original factory Rims:P265/75 R16

I like to put the P265/75 Tires on the Rims which are actually mounted on the car.

Possible?

I know,stupid question but the Man at Goodyear had no clue or het didnt wanna help:p

Yes. If stock size for your "car" is 245's then upsizing to a 265 will throw your speedo off by roughly 2 miles per hour.

yeah,that I know,but my speedo doesnt work so No problem..

question was more,if I can mount bigger tires on the Rims on which are the Workhorse Tires are mounted right now. (I think they arent the stock tires)

Phil,

The key to putting larger tires on, is not over doing it.
When you put a much wider tire on a narrower rim, the sidewalls are not vertical, which is where they were intended to be run at. This makes things seem a little wobbly when you run standard pressures in them. If you try to raise the pressure to get away from the wobble, they wear out in the center of the tread and really loose when breaking and cornering.

From your post, I can't figure just what's OEM and what's not, but...
Your 245/75/16 are about 7.2" wide.
Your 265/75/16 are about 8.0" wide.

That's not excessive IF you have OEM Rims and they were 7" wide.

The rule of thumb is that the Tire is not more than 1/2" narrower, or
not more than 1" wider than the rim.

You could break down one of the Tires, and measure the Rim Width just to make sure just how wide the rims actually are.

Let's start with all the info. What size are the rims that the 265's are mounted on now? What size are the rims that you wish to add these tires too? What kind of "car" are we talking about? Why would you think it wouldn't work if the "car" in question came with these wheels when you bought it? A 265 vs. a 245 is only one step up on the size chart. Other than being roughly 1" taller and less than 1" wider it will not make much difference unless you trying to mount these on a 4-5" rim.

Phil, just a side comment here, until you can get back with more info...

I'm two blinks short of being a fanatic, about getting the right tires on the right rims. One thing I've found over the years, that most times the qualifications for hiring a Tire Salesman in any given store, is that they have worked at Burger King or Jack in the Box for at least one week before getting fired because of incompetence.

So, I'm totally applauding that guy you talked to at Goodyear for being honest ! That'd be a shop I'd return to, after I got some solid info from a knowledgeable/trusted source.

And by the way...
The only stupid questions, are the ones that go unasked.
