Spare Tire Question

[Farmer Fran]

Was that goofy full-sized spare on a proper full-sized rim, so you only had to replace the tire, and then it became a useful replacement?

.

'To answer your question, from my memory NO!

I did not pay that much attention, I just dropped it to make sure if I need to replace it could do it in a pinch. Including all the jack points and where everything was located. My opinion unless you call someone like AAA or such it is a good idea to know how to replace a tire in an emergency, but that is a different thread. OH, and checked the pressure. Because not towing it would have been "fine".

This all said, going on memory I had the 22s on my Limited and this was a smaller rim (not overall diameter tire) and the tire was way skinnier. - remember on my memory.

Now my guess, all RAM trucks (less the special ones) have the same 32" radius overall and the same size brakes so no matter the rim this tire would work across the board.

For my situation I would have needed a fancy rim under the and thinking about it that might not have worked.

My car has fix-a-flat in the trunk LOL!

Are you talking about a specific model? I have a 2023 2500 that came with 17" wheels.

I also have a 5th gen power wagon with 17" wheels. I just put 35x12.5 x17 Pro Comp mud terrains with no problems.

I'm referring specifically to the 5th gen 1500. 18" is the minimum wheel diameter to clear the brake calipers. My OEM 18" wheels had about 1/4" clearance between the rim and brake caliper.

The newer HD trucks are 4.5 gen trucks (5th gen body (cab and bed), 4th gen everything else) so will support a 17" wheel.

I'm thinking you meant diameter, not radius.

And assuming you're specifically talking about 5th gen 1500's, your guess is incorrect. Rebels come with 33" diameter tires.

Everyone seems to have their own definition of what a truck is. While I agree that no pick up should come with a temporary spare, I don't agree that the spare tire that comes with it defines whether or not it's a truck LOL. It's easy enough to replace the spare with the tire/wheel of your choice.

Sadly, that is true in this day and age in so many ways. Nothing is what it seems anymore as the traditional definition of many things is not as it once was.

Not really sure what this has to do with anything but that’s quite incorrect… the 2019+ HDs have 4th gen cab and bed shells, everything else has been redesigned. That said I have no idea about the wheel sizes on them.

Thanks for the correction - I edited my post to reflect your info.

Thinking about new tires on my 2019 RAM 1500 and am happy with ride and performance on the original tires and plan to get identical replacements. I have never had a flat and assume the spare is identical with the original four tires. Since the spare is underneath the frame and never receives UV light or direct heat from the sun; is there any reason not to use it when replacing the tires, thus saving the cost of one tire?

I'd replace those tires with Pathfinders A/T from Discount Tire. They are great tires, good price, wear exceptionally well, have great traction, etc. I have these on three different pickups and would not trade them for anything. Spare question is you should take it down, check it out and put at least the regular poundage of air into it. cheers

I had to buy a full size spare to replace the temporary spare that came with my 2019 Limited 1500, which had everything except the 'hundred speaker upgraded sound system'! I needed to buy a new rim and tire for it... but it does fit where the original spare goes! I do a five tire rotation each time, too.

4 yrs old , I would keep the spare where it’s At . Air it up .

As far as putting a 4 yr old tire on the road , not a chance .
