Spare Tire Question

A few months ago I upgraded my worn out stock tires (I think they were 245/?/16) with BFG K02 265/75/16 All-Terrains and replaced my stock wheels with TRD Beadlock ones. When doing this I completely forgot about the spare. So not knowing anything about this kind of stuff, do I need to replace my spare tire with another 265/75/16 BFG? I would assume so since they are wider then the original. And if I do can I put the "new spare" BFG on the original wheel?
When you stop laughing at my questions I would appreciate your response.

 

Yeah it will fit. Back to lmao

 

Only of you use it in 4x4 iv your running 2wd and open diffs itll be fine

 

It's a legit question. You don't really need to put on a matching spare. There's not enough difference to cause a problem, even if you drive a hundred miles on the spare.

 

I agree with @Pigpen, but really you could go either way. For some, it's nice to have the matching spare because they add it to their tire rotation. But you wouldn't be doing that with a mismatched rim. The spare is really there for emergencies. If you primarily drive on the street, I'd say what you have is fine. May want to reconsider if you plan a long road trip. If you off-road however, I'd suggest a spare that at minimum matches the size, preferably the tread pattern too. If you have to rely on that thing to get you back to civilization, you'll want to ensure it's capable.

 

BTW - where did you end up buying your TRD Beadlocks from? I'm considering those wheels as well.

 

thanks for all the info everyone. Since most of my driving is just road and mountain road I will leave it as is. I got my TRD Beadlocks from the local Toyota dealer. I know what you are thinking but they gave me a really good deal since I know them well and cook BBQ for them.

 

The spare you have now is very close to the diameter of your new tires. Most of the difference is in the tire width.
I think the difference in diameter/circumference is like 3% of 245/75 vs 265/75. Pretty negligible, especially with open diffs and in an emergency situation.
For me personally, it wouldn't be worth my time/money to update the spare.

 

I have upgraded to 17” 4Runner trail rims on my TRD OR which had 16s, so facing the same issue.

Tire calculator says my new setup is 31.6 inches in diameter, stock wheels were 30.6 inches.

Is one inch difference enough to justify a bigger spare?

 

How long do you plan on using that spare before buying another tire? Six months or a week until the new tire is installed? If the former, then I would get a matching spare. Not worth it if the latter.

 

Not for me.

 

As others have said, you're fine as is. When you replace the tires you're running now, have them mount the best one to your spare.

 

Actually what I'm thinking is "Damn". That's about the only place I've found them and was hoping you had some secret hookup.

 

Many cars have doughnut spares that are smaller than the original tires. Not an issue for short periods as the diffs can make up the difference. However, if running off road away from civilization it is something you should consider, to get a more durable spare tire to more closely match whatever you are running on your other wheels.

You can buy the TRD beadlock wheels online:

You're 100% on point

 

Having a TRD Bead lock spare easily adds 100 horsepower

 

For awhile I had 11 stock steelies, all with the same load E 33" tire on them (Toyo M55). I gave away a set of 4 tires that were pretty worn - 2 of those had wheels on them. I'm down to 9 now. 4 with fresh studded, siped tires for winter (Dean Backcountry MT). 4 that are wearing down that I run in summer. Also, one as my spare. Those 5 are still the M55s.

 

I do recommend at least practice dropping your spare if you have never done it just to check the condition and most importantly, the air pressure.. Not the easiest initial process but the first time I dropped the spare after purchase, it had only 5psi of air and the sidewall had pressure grooves from contact at the frame due to low psi. I check the psi now every 6 mos and tire has to be dropped for that due to the valve stem being on the inside.

 

You can flip the spare tire so the valve is reachable from underneath the truck. Also, you could go the cheapo route I did and replace your 245 spare with a used 265 for about $20-$30 installed/out the door but check date on tire and make sure you’re not getting a tire that’s incredibly old. I had to look through quite a few at the used tire place to get a good dated one with similar and deep enough tread pattern, but it was worth it.

 

Turn the tire over.

Or use a valve extender.
