Just wondering what the most common tire size would be on semi and trailers and grain trucks. I blew a tire on the semi last week, and of course nobody does service calls in that area, but that’s a different story, and after I limped it about 40 miles to the next town with a tire shop the guy said he didn’t have any 24.5 drive tires. He had a used one at least. He said he didn’t stock that size because they aren’t that common anymore. Then the shop in town had to order a full set when I got them changed because they didn’t have any in stock, but he said that his brand was out of stock but usually tried to keep a couple around. Are 24.5’s becoming rarer or is it just that everything is getting so expensive that they just don’t want to be sitting on extra inventory?
And on a different note but still tire related, there was a 800/70R38 at the tire shop and was told the price was close to $8000. Have been looking around for a tractor and some have that same size, are they that much better than triples? At close to $60,000 to replace a set on a tractor it sure weighs on what a guy wants to pay for a used tractor. That’s about twice the cost of doing a set of triples.

Tire shops around here seem to have sets of 24.5 and 22.5 tires. Never been a problem to get that I know of. Put a set of 24.5 on our one truck in the fall and he had 2 or 3 sets in stock.
Those bigger tractor tires are getting ridiculous in price. Last time we were doing some pricing the 800s weren’t much more then a set of triples to replace.

Here they have both sizes as well, I think in part because some oilfield companies spec their trucks that way and forestry logging trucks are running high axle weights off road and the spill over effect of those used trucks into the local market. However I get the impression that a lot of super b trailers are going to have 22.5 and while its being spec'd that way its also a bit cheaper and the custom guys are always looking for the lightest rig so they can haul more. Transport trucks and trailers across Canada and the US, I believe that is a 22.5 world although not just the 11R size but metric aspect ratio sizes that fit the 22.5 rim. So I think we tend to be in somewhat of a bubble in parts of western Canada with higher usage of the 24.5 and more likely an issue to find supply of elsewhere. Interestingly in Australia from anyone I have asked, no one has seen a 24.5 as 22.5 seems to be the the size used.

Holy $hit , that much for a tractor tire ?
I am buying a pair of back scrapper tires that are coming off a jumbo jet liner ! Yep , 1500 bucks a piece plus install. I have to verify but these have super high ply rating. I thought he said 28 .
This is an old Allis chlamers scrapper from the fifties, still sporting the original tires. One blew out last year .
I tell you , the tires made now are a joke compared to back in the fifties with real rubber and good construction .
I actually liked 24.5 tires on the trailer . Gave a bid more clearance for the auger hopper .
Even my John Deere drill tires are on back order till July ! Good thing I have spares !
I can get galaxy brand tires instead of fire stone but I find galaxy tires don’t hold air !!!! That’s a big draw back !

22.5 would be more common on newer trucks, but as noted lots of 24.5 tires still in Western Canada.
Tires are definitely a consideration when buying something, I bought a Bourgault 6700 tank and it uses goofy rear dual tires that are a 650/75R34 and super uncommon....$7500 per tire and those tanks are getting to the age where they are failing. At least tires are a write-off so a deal on a used piece that needs tires might be better than a more expensive machine with good tires. At least if a guy puts a new set on you know where you stand and should be good for awhile. This has been my strategy lately, but I have a real good tire shop and they like trade-ins as some guys just want a cheap used tire to get them going.

Speaking of truck tires, I'm seeing more and more of these large singles on trailers, and even for drive tires on the odd truck. What is the benefit of running these tires? Biggest downside I see is when you get a flat, you are not going anywhere. At least if one of the duals fails a guy can still limp the rig somewhere just like kevlar did. I'm thinking traction would be worse too, but maybe I need to be educated.  |

I think they're lighter then a set of duals. My uncle tried putting them on their tandem and it got stuck easier

Lighter and better mileage. But you’re stuck on the side of the road when you get a flat.

Normally see the big singles on LTL carriers who basically are all hiway running with van trailers. As Meskie said they use them for better mileage.

I don’t think you’ll see as many around here, more of a southern thing running on interstate highways. I know of a couple guys that tried them but only once. If you’re lucky you’re only stuck somewhere with a flat, if it’s on the side of the highway you have a flat, need a new tire, and a new rim because 9 times out of 10 it will be screwed by the time you get pulled over.

I remember close to 20 years ago that I ran across up in the Yukon, he had converted his small single axle mack truck to big singles for the rear and he had just sold his towing company in northern BC. I questioned him about the issues of having a flat and and being screwed as there is no way to limp ones self along but he seemed to think they were great. I believe he was using that truck to tow a fifth wheel trailer.
A friend of mine years back in working for a well known large oilfield service company, they tried a truck with big singles and not sure if they actually got it up here or not but he said it was a scary mess on a winter road and I've forgotten the details but the short answer seemed to be that there was no way they were going to be using wide singles on their oilfield trucks up here. I could be wrong but have gotten the impression Europe is where the idea got going as I've seen video of trailers with them over there for sure.

When we were in Germany a few years ago all the trucks we saw had super singles on them.

Definitely guys with the super singles on super B trailers over here.
Do they have the same weight rating as the regular duals? I thought I heard that they have a lighter weight rating.
