Hey all. I want to mount a tire on my stock spare rim that will be the same diameter as my 285 75 R16's. What is the correct tire for the same diameter on the stock rim? Don't care about width.

TIA

Aren't your stock wheels 16"?? Why not just mount a 285??

Maybe I don't understand!!:confused:

It does on a NBS 1/2 ton, but I have never tried it on a 3/4 ton.

Sorry guys maybe I wasn't clear. I have aftermarket rims on the truck that are the proper width for 285 75 16's. I just want a tire that will fit on the narrower stock spare rim that's the same diameter and the proper width.

Spare

This is a 305-50-20, 32" tall, in the spare space. Also notice the rearend cover is larger. The tire has to be held back against the hitch. Make sure your new rim alows the holder on the cable to go in the reciever and catch. See the other pictures in 305-50-20 on stock 2500HD. Try to match what you have, rim and tire, for a spare. Used is OK

Ok, we are getting closer. I will be using the STOCK spare tire rim.

I have a 285/75r16 on the stock spare (steel)wheel, fits like a glove.

Would there be any issues towing with this wheel tire setup? I have heard of some shops that won't even mount this setup for you.

I don't have any problems with mine (BFG 285/75R16) and I tow a 12000# toy hauler, have towed our cattle trailers and even a small building. To me it feels better with bigger tires, extra cushion; load rating is higher than the stocker's too.

285's fit just fit on a stock 16X6.5 wheel. No worries!

A 235/85x16 is about the same height as a 285/75x16, but it is made for a 6.5wheel. Most 235/85x16 are E rated so you will have no problems towing with them. I think that is really the answer you were looking for.

you'll never get anything bigger than a 30" dia. tire up there if you have a real hitch (read: not the junk stock hitch -:t ).

265/75-16 Dueler will not go up with a Putnam XDR. I suspect the same is true for the Reese Titan. ;)

and of couse this is with a stock rear cover...

A 255/85/r16 is almost exactly the same diameter as a 285/75/16. I actually have BFG 295/75/16 ATs on my truck and run a BFG 255/85/r16 MT for the spare. I prefer to run a narrower spare so that it does not hang down so much when it is stowed. Plus the 255 tire is much cheaper than either a 285 or a 295 sized one.

I have a 285/75R16 BFG M/T under there as my spare. Fit up there easily. I think that's a 32" tire IIRC.

That's exactly what I was looking for! I think I'll go with the 255/85 16's. closer to the diameter of 285's

Thanks

I am a purty strong advocate of correct wheel size for a given tire, but you would only be using it until you could fix the flat...right? May not be an issue just to get out of a perdicament. However, I think the 255/85/16 is purty close to the 285 in height and requires a wheel width of 6.5" - 8", which means you have no issues towing or otherwise. I looked on Tire rack and the BFG 255 (aggressive tread) is just 33.3 inches tall, and the Dunlop 255 (looks more like an all-season tread) is 32.8 inches tall. Both have a 3000lb carry weight rating. So, you could see what your tire height is and choose the closest one. Remember a 1/10 or two is no big deal as air pressure could vary your tires by that much. Good luck.
