Considering 2nd spare tire

[chaps2018]

We have had our share of blow outs. Immediately after getting back on the road our first priority is to get the tire repaired/replaced so we are not stranded (yes we have good sams ers).

We are considering getting a 2nd spare.

Question do you guys —- how many times have you lost two tires in one day?

I haven't lost two tires at once, but I'm about to get a second spare for an upcoming trip to Texas this fall. Hopefully I won't need either spare , but if I do I have it.

How about one on one day and one the next day!

Lost two tires in two miles,had to leave the fifth wheel on the highway to get tires. I have two spares now.

If you have a failure doing highway speeds where the tire comes completely apart before you get stopped, chances are the adjacent tire on the same side will fail in the near future. Has happened to me multiple times with several different types of trailers.

Would I carry two spares? I have two spares, but I only carry both when we are going far into the backcountry on long dirt roads. Otherwise, it just takes up too much room.

And yep, we lost three tires in one day. 18 month old OEM tires that were well maintained. That was a long day.

Had a massive blow out and the other tire on the same side just went totally flat. Had to call our road side service company and had them bring out two tires.

I think a more important addition is adding a Tire Pressure Sensor Monitor (TPSM) to your rig. Most blowouts are due to under inflation and the TPSM will alarm and prevent these kind of catastrophic, dangerous and RV damaging events. Since I have installed them, they give me a peace of mind that i never had before. How many times do you feel something different while driving? Is that the road or is it my tires? With the TPSM I look up at my green LED and i know that all my tire pressures are within the alarm limits I set. If any of my 6 tires (rear axle is a dually) drops below 50 PSI, then I get an audible alarm and a red LED. I am able to pull over in time to prevent a blowout and overheated shredded tire that would have definitely happened without the TPSM alarm.

So to the answer on the 2nd spare tire. The probability of you getting 2 flat tires very close together is very improbable.... UNLESS your are doing some high risk bad road driving. For example... I would never do the 120 miles of dirt road with razor sharp rocks of the Denali highway in Alaska without a 2nd spare tire. Or any serious off road driving in remote areas. But for normal highway driving, I do not think a 2nd spare is necessary. Yes there is always the possibility of road debris causing multiple tire failures, but not probable.

Haven't had a flat on my trailers -ever- well over 25 years.
My current rig is pushing 20000 mi on original tires.
I always have a large safety margin maximum load rating vs actual cat scales weight.
If you ask folks who've had problems you get skewed results compared to overall actual % of total RVers.

I just had to blowouts during the same trip. 90 miles apart. Only had one spare! Second blowout damaged the wheel also. I had to unhitch and leave the RV on the side of I-45. Not much around but the next town had a tractor supply. $185 bucks later I had a wheel and tire that would fit. Getting a replacement wheel delivered next Wednesday. I will not have to spare tires/wheels. Hard lesson learned

On a trip with my bother and his family. He lost 3 tires within 150 miles. A 3 hour trip home took almost 8 due to the number of pitstops (literally). Tires were brand new... First trip out.... Bad batch failed in 100* weather.

We have 2 spares now.

Dan,
What brand of tires do you run on?

[Life is great]

I blew 2 tire twice! I will always care 2 with me at all times from here on out.

I have carried a second tire non-mounted tire, for extra insurance.

Very good point, I should’ve mentioned that I use the TireMinder smart TPMS. The main reason I got the TPMS in the first place is that while I’m pulling my rig with the 1 ton Dually I can’t “feel” when I have a flat on the trailer.

I got to a point where I was almost afraid to look at somebody passing me for fear that I will get the crazy waving and pointing at my wheels.

Can't hurt.


I see a trailer at the storage yard where I keep mine that has two spares on his back bumper.


Now that you bring it up, I might start doing that too.


For regular flats, I carry tire in a can for short jaunts to a tire shop.


I did carry two spares on an alumnum boat trailer before as we used to tow long distances to far away lakes.

The tires that came on my current rig are 3 years old and have ~ 20,000 miles on them.
They still have good tread well above the "wear indicators".
They are TaskMaster Provider ST Radials.
According to the Taskmaster website they supply 40% of the towable market.
Provider ST Radial - Taskmaster
Donno if that's true or not.

My particular tires are
ST 225/75-R 15
Load Range D Speed rated M - 81 MPH
Load capacity 2540 x 4 = 10,160 Lbs
My rig at the CAT scales ready to camp ~ 6800 Lbs.
Safety margin ~ 3360 LBS
(About 67% of max)

We towed across AZ and NM and OK this summer at temps well above 100 at speeds 65-75 depending on how fast the trucks were running.

I'm very happy with them and they are on the rig just through the luck of the draw- what came on the rig.
IF I can find them I will definitely buy them again when the time comes.

When I bought my trailer I immediately replaced the China bomb tires with Goodyear Endurance tires. I got a couple of rims and mounted two of my China bombs to use as spares and I just leave them in the back of my truck. And if all else fails, I also have the spare that came with my trailer. So, three spares for me. I wasn't taking any chances when I pulled my trailer from Arizona to Alaska. Replacement tires and places that fix tires are far and few on the Alaska Highway. I'd rather have too many spares and not need them than have too few spares and need more.
