Trailer tire pressure

14 posts in this topic

Does anyone know for sure what smaller trailer tires should run for pressure. I picked up some Carlise 4.80 x 12 rim and tire for my boat trailer this weekend and there was a sticker saying to inflate to 60lbs. cold.(this is what the side wall says is the max pressure) Am I crazy thinking that this is way too high? Any good advice is appreciated. It seems I can only get a few thousand miles out of these tires before they are shot.

I was wondering that about my snowmobile trailer. Should I run at max pressure all the time? Load or no load, cold/warm?

Smaller tire diameters need higher pressure to dissipate the heat generated by speed and heavy loads. There have been past threads questioning the quality and durability of Carlisle tires.

I always fill to recommended pressure. I have noticed that, as IFallsRon says, they get hot if underinflated.

Inflate them to the max tire pressure as displayed on the side wall.

Go to the max pressure, even if empty. 60lbs is normal.

Oh, that's why my trailer tires always very hot even after a short trip. I thought my truck's tire needs only 33 lbs, why my trailer tires said 50 lbs, LOL.

Do 60 pounds of pressure, unless you want to blow out your tires.

A more complex answer just to throw a wrench in the machinery...

Every tire has a pressure vs load capacity. Now, for some it's very hard, if not darn near impossible to find this data, but that is where the most correct inflation pressure comes from.

Too much air and the the ride is overly rough and can be damaged by shocks/impacts, too low and the tire runs hot, harder to pull, etc.

Here is an example from Goodyear. You find the tire style, size, load rating and then you get the tire load vs. pressure details. So, if you know the weight of the trailer and load, you can then determine the "optimum" inflation pressure - again, provided you can locate the load table.

Another point I see often ignored with trailer tires is the maximum speed rating. I see many trailers with 8 or 10 in. tires being towed down the interstate at 75-80 mph. These tires are probably rated for 55 mph max. Some of the 8" are only rated for 45 mph. Part of this is because of bearing speed. That small trailer tire is turning more than 4 to 1 compared to your trucks tire. Lots of extra rpm there. If that tire is soft (low air), all the extra sidewall deformation will really generate heat too.

I think that I will stick to the 60lbs. Thanks for all the insight. Also, have any of you found a good durable tire like this if the Carlisle isn't very good???

Carlisle is the low end, Good year are a good brand but not easy to find

Are Carlisle tires really as bad as I am hearing and reading on different forums? I have a set on my Eagle trailer now that are 3 yrs old but look to be in good condition with about 4500 miles on them. Is it true that a lot of them are re-treads? Pretty close to switching them out for Goodyear Marathons.

Carlisles.. are round and they roll. They dont last very long and there has been way too many issues with them. Some due to operator error(tire owner), and way too many other problems just because they are a poor quality tire, but they are economical and popular because of it. I think all trailers that have 12" and 8" wheels come with Carlisle tires standard... because they save the manufacturer money, and they are readily available.. not because they are a decent tire(they are not). Its similar to the Firestone situation with Ford in the past, and notice most light trucks had Good Year Wrangler RTS tires on them for a long time? Manufacturers put tires on that are cheap.

If you are stuck buying Carlisle because of availability, buy more tire than what you need(higher load range) and you shouldnt have so many problems, but they will not last as long as a quality tire. Keep your tire properly inflated to max pressure(usually somewhere between #40-#80 psi).

Over loaded tires are going to be a problem no matter what brand they are.

      Just started playing with these this week as a friend has been have goos luck all summer with them on the Cass lake chain. I have not any success yet but not real sure on the best way to use them with my set this week.  My friend searches pods of fish out with electronics then spot locks and vertical jigs. I have no electronics or spot lock so I have been control drifting and jigging.   My questions...   Is there a depth they work better in, shallow vs. deeper?   Better vertically jigged vs trolled vs casted and jigged?   prime colors? of course my be lake dependent.   typically, aggressive jigging vs subtle jigging?   Thanks for tips

      Yes, insured. I will ask the adjuster, thanks.

      Thanks cliff and lb I have actually had better luck with the puppet minnows from northland but I have mainly jigged them vertically definently is a fun way to fish

      I've been trolling at about .5mph while using a jigging rap. This way one guy can still drag a lindy. I keep the front hook intact but my boat has contributed about half a dozen to the lake so far this summer. Im still working on getting the hang of it. If I know I'm in a rough area I will attempt to keep the jig from hitting bottom which still seems to be effective. I did pick up a couple off brands that don't have a front hook that I want to try. This is just what I have been toying around with, I'm definitely not an expert at it.

      Hi Everyone, a couple of questions, I know there is free public boat ramp in Stillwater just above the lift bridge. Is there another public boat ramp further down river? I thought I read somewhere that Beanies is or was becoming a free public boat launch. Is that the case? Also, I am thinking of heading there on Monday to try my luck. Any tactics/depths/areas that have been producing for anyone?

      I would call the catfishing this week seasonal.  It is a pretty normal bite for a period of lower water and heat.  The catfish are in post spawn and spread out in their summer haunts.  The more aggressive fish are in the deeper water in the middle of the river.  As usual stay on the move and keep the bait fresh. Bait does not seem to matter still but people with frogs are saying they are getting their better hits with them.

      Wildlife artists can submit entries for the 2018 Minnesota Trout and Salmon Stamp through 4 p.m. Friday, July 28, according to the Department of Natural Resources.  2017 Trout and Salmon Stamp Competition
      First Place: Timothy Turenne Anglers can purchase the trout and salmon stamp validation with their fishing license for an additional $10. For an extra 75 cents, purchasers can receive the pictorial stamp. It is also sold as a collectible for $10.75. Revenue from stamp sales is dedicated to trout and salmon management and habitat work. Trout or salmon must be the primary focus of the design, though other fish species may be included in the design if they are used to depict common interaction between species or are common inhabitants of Minnesota’s lakes and rivers. Brook trout designs are not eligible this year. Artists are prohibited from using any photographic product as part of their finished entries. Winning artists usually issue limited edition prints of the artwork and retain proceeds. Judging will take place Thursday, Aug. 3, at DNR headquarters, 500 Lafayette Road, St. Paul. For more information and contest guidelines, visit mndnr.gov/stamps, or call the DNR Information Center at 651-296-6157 or 888-646-6367. Discuss below - to view set the hook here.

      It was a main lake break line that went from 18' and dropped into around 30'.  Just a sand transition into mud.   The fish we kept were loaded with small perch and crayfish.

      For winter jigging with Raps I cut off both front and rear hooks and upgrade one size on the middle treble hook. Cliff
