Power King Towmax tires

I would love to chat with yall more about your tire issues I have had my Raptor 300MP for under 3 years and have blow 2 tires now. I always have them
Properly inflated cold at 80psi and I blew the right front in October of 2014 and the left front yesterday. Both have occurred while traveling at 60 mph or less. My camper stays parked on a concrete slab when not in use and moved and used monthly. So no dry rot no visible issues when checked before or at any point during a trip. I would say the tires have maybe 6-7k miles on them if that. I am curious as to what you had blow ( ie location of the tire on the trailer) and what brand tire. I have Power Kings. I and wondering if this is a tire issue or a design flaw with the 300MP that keystone is responsible for. Either way I am at the point to where I am going to hold both parties responsible. 1 keystone has been notified by varies parties over the years and continued to use these tires and 2 there seems to be more of and issue than just on raptor toy haulers so the tire company know they have an issue. I am also going to contact the NHTSB regarding this matter

Welcome to the forum. From your posts, I'd gather that you are frustrated with the Chinese tires installed on your RV. Many other members share your frustration. If you open the forum section titled "Tires, Tires, Tires!" you'll find 14 pages of threads concerning tires. Of those 14 pages, the subject of nearly half those threads is the reliability of the Chinese tires that RV manufacturers install on RV's. It's not just Keystone, rather virtually every manufacturer uses similar tires.

Take a few minutes (it'll probably be an all nighter) and review some of the threads concerning tire reliability, maintenance, storage and member's perspectives on ST tires.

I see all these threads about tires but my question is does anyone take there camper in to have the axles aligned. I bought my camper and took it to alignment shop and the we're out of alignment by a lot . I'm not sure all the blame can be put on the tires . Bad alignment leads to tire wear, heat build up which in the end equals blown tires . Just my opinion

First thing I did to my new fifth wheel was to replace the Towmax "blow max". I went with Maxxis 8008 tires. I have had no trouble with them. Have them on the RV, boat trailer and cargo trailer. I have the Mor/Ryde LRE 4100 suspension so having it aligned just anywhere is out of the question.

That's what I did after considering the possibilities with the OEM Chinese tires. Peace of mind has resulted.

They may well be junk waiting to blow. But, really many people driving all type of vehicles with all types of tires have flats and or blow outs. I know due to seeing, helping, being dispatched to them and hearing other police almost daily going to people with flat tires. Much needs to be known with regarding to why and most times all we know is a tire blew. Lets say you checked the psi everyday as you should before travel and it was always 80psi. How was the tread, do you check it before travel, look for splits, goose eggs etc. what was the wt. on each axle and tire. Than remember the trailer tires track outside of the TV tires and go over other parts of the road as do the TV tires. When we hit anything with the TV tires we know right away due to the sound of debris stuck in a tire. We cannot hear that on trailer tires. We can feel the TV shift wt with a flat, maybe not so on the trailer. It is easy to drive for miles on a low trailer tire and not know it. Getting a TPMS system to help find out what's happening will help. Along with proper tire inspections. Some tires maybe be junk but, most (about half all come from China) so I am not convinced that it's always the tires to blame.

Look at it from the Thor/Keystone point of view. The tires are manufactured according to industry accepted standards and they are DOT approved. Thor would gain very little by installing highly regarded Maxxis tires as standard equipment. If Thor installs Maxxis tires as standard equipment, raises the base price by $500, then loses a sale to Forest River because they were $500 cheaper; and the buyer couldn't have cared less about the tires. We complain about the Chinese tires, but my Maxxis were made in Thailand.
As owners we can either go to a higher regarded tire (Maxxis), or a tire that has a much higher rated load capacity than is needed; G rated for 16" wheels. That opens the can of worms of wheel capacity and another drain on the bank account.
So what did I do? Got the Montana home and ordered Maxxis from Discount Tire. Sold the BlowMax's to a neighbor for a stock trailer.

My 300MP came with similar tires. They were terrible. I replaced mine after just 3 trips. The tires bulged with 80 psi with an empty trailer. The dealer got me on those. Replaced mine with Taskmaster Provider F385's. 235 85 16 G rated tires. Rated at 4080 lbs at 110 psi. These tires are much appropriate for the 300MP. Discount Tire has a great deal in these right now. Good luck

My life experiences show gearhead got it right. This is what I found. Every Vehicle I ever purchased from Nissian, Ford, Chev that had factory tires were only OK. The local tire shop always has better tires. All the OSP game vehicles are SUVs or P/Us. When they come to the office as new, off go the factory tires for better ones. Other wise you blow out cheap tires on lousy roads. And those vehicles are not used like your normal vehicle. Patrol cars come with some great tires that I doubt others buy to to high prices and no need for high speed rating. Why would RVs be any different. If I wanted a Airstream, say 28ft. retails over 90,000 bucks new according to the adds, maybe they have premium tires, I do not know because I am not in that market.

My last three Ford pickups came with Michelin tires.....I'm betting GMC and Dodge came with the same or equal Goodyear ......

Talking

Luckily, I had only two near misses with the original tires, One tire leaking was caught in plenty of time to pull over by my Tire Minder TPMS. During an annual state inspection, Inspector noticed bands on tire were starting to go. Tires had near 9K miles on them. Inspector had to show me a few times where the problem was by rotating it before I noticed it. I do not think I would have picked that up.

That was enough for me and after reading various comments from this forum decided to replace all of them with Carlisle Radial Trail ST235/85R16 F rated tire, 3960 at 95 PSI.

Jim, If those same tires can be purchased at a tire shop, than I would think their are better than some I have had say, Toyos that came on a new vehicle that NO tire shop had or could get. I found out when Elk hunting and putting a hole thru the thin side wall. That was a few years ago. The last new truck tires were as I recall named steel tex. They were ok but, not great.

Just a factual note; The power King Towmax ST235/80R16E tires have 100# more load capacity per tire then the Maxxis ST235/80R16E with both at 80 psi.

CW, I don't quite understand your comment about the Towmax tires. Are you promoting them, or just stating what the manufacturer claims? I think we've pretty well determined over many conversations on this site and a number of others that the Towmax tire is garbage.

You can check NTSB complaints here:
http://www-odi.nhtsa.dot.gov/owners/SearchSafetyIssues

Interestingly enough TowMax shows 11 complaints - all fairly recently... Probably worth checking complaints on the OEM tires.
